The cell wall is a non-starch polysaccharide and consists of various bioactive moieties. In addition, it has many functional and nutraceutical properties. The main purpose of this present research was to extract the cell wall from different cereal bran and to characterize it for nutritional and bioactive properties. In addition, the effects of the cereal bran cell wall (CBCW) on functional and rheological properties of wheat flour were elucidated. For this purpose, the cell wall was extracted from different cereal bran (maize, oat, and wheat) via an enzymatic method and characterized for its monosaccharides and phenolic acids contents. Additionally, the rheological properties of wheat flour with the addition of CBCW were determined using the farinograph and mixograph. The results showed that the cell wall contents in oat bran (43.31 ± 1.41%) were higher than those in wheat (41.53 ± 0.09%) and maize bran cell walls (37.31 ± 1.05%). The maize bran cell wall has higher arabinose, xylose, galactose, and glucuronic acid contents, followed by oat and wheat bran cell walls. Furthermore, the oat bran cell wall contained higher total phenolic acid contents as compared to maize and wheat bran. Nevertheless, the ferulic acid content was high in the maize bran cell wall. Moreover, incorporation (2%) of CBCW significantly improved the rheological properties of wheat flour. The water absorption (66.04 ± 0.23%), dough stability (4.54 ± 0.6 min), peak height (66.02 ± 0.03BU), and mixing tolerance index (70.02 ± 0.07%) were high in wheat flour with the addition of oat bran cell walls followed by wheat and maize bran cell walls. Furthermore, the dough development time (6.75 ± 0.25 min) was the highest in the control sample and the lowest mixing time was observed in C4 (5.41 ± 0.12 min), while the softness of dough (139.4 ± 0.02%) was decreased more significantly through the oat cell wall than wheat and maize. Conclusively, CBCW contained different bioactive moieties that have numerous positive effects on the rheological and functional properties of wheat flour.

Much recent researches have demonstrated that the quality of freshly-harvested wheat could be improved during postharvest maturation by determinating the rheological properties. However, this process is time-consuming and complex. This study aimed to provide a rapid and convenient method for predicting wheat quality during postharvest maturation by use of GlutoPeak device. Farinograph and Extensograph were used to determine the rheological properties of four wheat samples (WT1, WT2, WT3, WT4) stored under different conditions (WT1: 15 °C, 50% RH; WT2: 20 °C 65% RH; WT3: 28 °C 75% RH; WT4: 35 °C 85% RH) for a total of 10 weeks, and GlutoPeak test was used to determine the gluten aggregation properties of the four samples. Correlation analysis was also conducted between the rheological properties and the gluten aggregation properties. Results of rheological properties showed that all Extensographic properties (dough extensibility, resistance, maximum resistance and area) of the four samples increased along with the storage time, and the Farinographic properties (water absorption, dough development time, dough stability time, and farinograph quality number (FQN)) had the same tendency, indicating that the rheological properties were improved considerably with storage time extending. The GlutoPeak curves revealed that Peak Maximum Time (PMT), Brabender Equivalents Maximum (BEM) and Energy to Maximum Torque (EnMT) of wheat flour of the four samples varied greatly, particularly the PMT and EnMT of the samples WT3 and WT4 increased remarkably. Results of correlation analysis showed that EnMT had significant correlation with water absorption and area (P

This assay was performed to select chemical compounds and rheological parameters for the prediction of the bread volume and crumb firmness of breads made with a blend of wheat flour-fine bran, using multivariate analysis. Two main factors were used, the source of fine bran and the particle size of fine bran. The experiment consisted in a completely random design, in a 2 × 3 factorial arrangement, the statistical analysis shown that the particle size of fine bran influence almost all the analytical variables. In addition, discriminant analysis was performed to analyse which rheological parameters and chemical components show the greater influence on dough behaviour and bread quality. Biaxial extensional viscosity, farinograph consistency, dough development time and stability were the main rheological parameters that govern the specific volume and crumb firmness and, were both closely related to the fibre, protein and starch content in the flour-fine bran blends. Particle size-genotype interaction has a significant influence on gelatinisation enthalpy and biaxial extensional viscosity that change the bread volume and the crumb firmness. The simplicity of linear equation of five independent variables to predict bread quality with high levels of accuracy could be advantageous in both basic research and the routine quality control of wheat mills.

The enrichment of semolina bread with prebiotic ingredients such as β-glucans may exert health-promoting effects. This work presents the results of a general recipe development aimed at improving the nutritional value of bakery products. In this study, increasing amounts (0%, 2%, 5%, 7%, and 10%) of thin bran or barley flour were added into re-milled durum wheat semolina to prepare breads. The technological quality of doughs and breads was investigated. In general, the Farinograph water absorption of flour and dough stability increased with increasing inclusion levels of barley flour or thin bran (up to 73.23% and 18.75 min, respectively), contrarily to the increase of dough development time only in barley inclusion (4.55 min). At the same time, the softening index decreased for almost all of these, except for 2% of thin bran or barley flour inclusion. At Mixograph, mixing time increased (up to 5.13 min) whilst the peak height decreased. The specific volume and hardness of loaf differently decreased for almost all thesis (ranges 12.6–24.0% and 39.4–45.5%, respectively). The other quality parameters remained unchanged compared with semolina bread. After baking, β-glucan levels increased differently at all the inclusion levels (2.35-fold, on average). The breadcrumb color was deep brown, while the crust became lighter in color. The breads contain β-glucans even at low percentages of barley/bran inclusions while maintaining their technological performance. In conclusion, the results show an interesting potential of barley flour or thin bran as ingredients in breadmaking to increase the β-glucans daily intake, but further investigations are needed to achieve improved quality features.

Jakost pšeničnog brašna uobičajeno se ispituje pomoću različitih uređaja za određivanje reoloških svojstava, a jedan od najzastupljenijih je Brabenderovov farinograf kojim se mjeri otpor tijesta na miješanje i gnječenje u mjesilici uređaja. U svijetu postoji nekoliko standardnih metoda za provođenje farinografskih ispitivanja (ISO, AACC, ICC), ali niti jedna od njih ne predviđa upotrebu površine farinografske krivulje kao parametra za evaluaciju kvalitete brašna. U ovom radu se ispitala povezanost površine farinografske krivulje i ostalih farinografskih parametara, zatim ekstenzografskih pokazatelja kvalitete, kao i udjela proteina te vlažnog i suhog glutena. Ispitivanje je provedeno na 66 različitih sorti ozime pšenice, a površina farinografskih krivulja određena je primjenom računalnog programa za analizu slike ImageJ. Utvrđeno je da postoji statistički značajna korelacija između površine krivulje i udjela vlažnog glutena, farinografskog kvalitetnog broja i stupnja omekšanja te energije i rastezljivosti tijesta određenima ekstenzografom. S obzirom na dobivene rezultate može se zaključiti da se mjerenjem površine farinografske krivulje mogu uspješno odrediti kvaliteta i pecivna svojstva brašna. The strength of wheat flour is commonly tested using various devices to determine its rheological properties. One of the most commonly used devices is the Brabender Farinograph, which measures the resistance of the dough during mixing and kneading in the mixer of the device. There are several standard methods for performing farinograph tests worldwide (ISO, AACC, ICC), but none of them provides for the use of the farinograph curve area as a parameter for evaluating flour quality. In this study, the relationship between farinograph curve area and other farinograph parameters as well as extensographic quality indicators, protein content, and wet and dry gluten content was investigated. The study was conducted on 66 different winter wheat cultivars and the area of the farinograph curves was determined using the ImageJ computer program for image analysis. It was found that there was a statistically significant correlation between the curve area and wet gluten content, farinograph quality number, degree of softening, and energy and extensibility of the dough, which were determined using the extensograph. The results suggest that by measuring the farinograph curve area, the quality and baking properties of flour can be successfully determined.

Mealworms (Tenebrio molitor) are protein-rich edible insects that have been regarded as novel food ingredients. In this study, high-gluten wheat flour was formulated with dried mealworm powder at various levels (0%, 5%, 10%, 15%, and 20%) to study its influence on the pasting, farinograph, and extensograph properties and microstructure of the dough. A subsequent decrease in the pasting parameters was observed due to starch dilution. The water absorption, dough development time, and dough stability time decreased gradually from 71.9% to 68.67%, 13.6 min to 10.43 min, and 14.1 min to 5.33 min, respectively, with the increase in the substitution of mealworm powder from 0% to 20%. The farinograph characteristics corresponded to a weak gluten network formed through the dilution of gluten by the replacement of wheat flour with a non-gluten ingredient. The stretch ratio of the high-gluten dough increased gradually from 4.37 (M0) to 6.33 (M15). The increased stretching resistance and extensibility of the dough with 5% and 10% mealworm powder indicated that mealworm powder can act as a plasticizer in the gluten network, which might contribute to the decreased strength and increased elasticity and flexibility of the dough network. The bread made with three different baking methods showed similar increases in specific volume and decreased hardness up to the 10% substitution level, owing to the increased elasticity and flexibility of the dough. The GB/T 35869-2018 Rapid-baking method, GB/T 14611-2008 Straight dough method, and automatic bread maker method exhibited the highest specific volumes of 3.70 mL/g, 3.79 mL/g, and 4.14 mL/g when the wheat flour was substituted with 10% mealworm powder. However, 15% and 20% mealworm powder substitution markedly reduced the bread quality owing to the dilution effect and mealworm powder phase separation. These results provide a perspective on the relationship between the rheological properties of mealworm powder-substituted high-gluten dough and application suggestions for insect food development in the food industry.

This study was carried out to examine the utilization of garden cress seeds gum(GCS gum)and Arabic gum in processing pan bread. Rheological properties of dough, physical properties, sensory properties, color parameters, texture profile analysis and bioactive compounds(total phenolics content(TPC)and total flavonoids content(TFC))were determined. Extracted GCS gum and Arabic gum were used to prepare pan bread at the rate of 0.1% GCS gum and 3% Arabic gum.The pan bread samples were prepared by partially replacing the wheat flour by 5, 10, 15, 20 and 30% of garden cress seed flour(GCS flour).Results of farinograph and extensograph indicated that addition of Arabic gum with the concentration of 3% improved stability,elasticity and degree of softness in compare with those of control and GCS gum samples. Also,results of physical properties namely weight,volume, specific volume, density, height and index to volume showed that pan bread samples with GCS and Arabic gum 5% were nearly in the same values with control sample. Results of bioactive compounds also showed that addition of GCS gum and Arabic gum increased the amount of TPC and no significant difference observed in TFC.When, DPPH% assay in all pan bread samples was increased in compared with the control one. All pan bread samples didn't show observed changes up to 5 days of storage under different storage conditions(room and refrigerator temperatures).Spoilage was pointed out by black, gray, brownish yellow and green coloration on the pan bread samples. It is recommended that addition of 0.1% GCS gum and 3% Arabic gum improved pan bread properties.

The paper is devoted to solving the problem of the nutritional and biological value of rye-wheat bread by enriching it with non-traditional local plants raw materials – linseed flour and rice husk fiber. Rice husks are rarely used in bakery production, and in most cases remain unprocessed. However, this research defined the right ways for using them and set as a preliminary work in this field. The study has been carried out in two stages: firstly, linseed flour was added to the rye-wheat bread recipe in an amount of 5; 10; 15; 20% to the weight of wheat flour. Secondly, dietary fiber was added to these experimental samples, prepared from rice husks without removing amorphous silicon dioxide in an amount of 0.3; 0.5; 0.7% to the total mass of rye-wheat flour. The optimization of the ratios of the flour components with a simplex-lattice design was carried out and the rheological measurements of dough and bread were conducted on the farinograph and Chopin alveograph. The study results experimentally found that mixtures of rye-wheat flour and linseed flour with the addition of fiber as “medium in strength” give bread with sufficient volume. The recipe optimization parameters indicated that rational percentage of fiber and linseed flour up to 0.5% and 15%, respectively allows increasing the nutritional and biological value of finished products, improves the crumb structure, gas-holding and water-holding capacity of bread, which in turn prevents the stale process and thereby increases the shelf life of finished products. The obtained results allow us to suggest that, this recipe optimization model could be used in further research, as studies in this direction are limited

Adding oat products to composite mixtures during baking increases the biological value of a new product. The purpose of the current study was to assess the biochemical properties of grain of the naked oat varieties ‘Baget’ and ‘Bekas’, to establish the rheological parameters of dough mixtures obtained by mixing white oat flour and whole grain flour with high-quality wheat flour according to the farinographic analysis. The introduction of oat products into the mixture affects the structural and mechanical indicators of the dough and can improve or worsen the quality indicators of bakery products. It is the decoding of the diagrams (Brabender farinograph, Chopin alveograph, etc.) that satisfy the questions related to the study of dough, with the characteristics of the physical properties of dough. There has been established a high nutritional grain value of the naked oat varieties (whole grain and white flour), when the protein percentage was on 5.3–7.6% more than in wheat flour and oil content was almost 6–5 times higher, which indicated great opportunities for using this grain crop in bakery. The study of the rheological parameters of dough showed that in composite mixtures the type of ingredients (whole grain flour, white flour) and the proportion of naked oats products (10, 20, 30%) differently affect the physical properties of dough, i.e. in relation to premium wheat flour, dilution of dough increases on 40–140 u.f., resistance of dough to extension (stability) reduces on 2.5–6.0 min and valorigraphic number reduces on 10–36 u.v. When mixing with white oat flour compared to whole grain, the physical properties of the dough are characterized by the best indicators, however, the introduction of whole-ground oat flour in the mixture retains all the benefits of oat grain. There were no significant differences between the naked oat varieties ‘Baget’ and ‘Bekas’ in the effect on the rheological parameters of the dough. When using oat flour in mixtures, there was identified a tendency to deterioration of the physical properties of dough, the differences were significant in terms of the resistance of dough to extension (stability) and valorigraphic number.

This research aimed to study the effect of addition moringa and turmeric powders on some properties of pan bread. Moringa and turmeric powders were added with the ratio of 5%, wheat flour and oat flour in order to prepare coloured pan bread. Chemical composition, mineral content, antioxidant activity, rheological properties and staling rate of pan bread samples were studied. Obtained results indicated that addition of moringa powder increased the amount of protein, ash, crude fibers, minerals and antioxidant activity in prepared pan bread samples. While, the carbohydrates content decreased in compared with those of control samples. Rheological properties also resulted that addition of Moringa and turmeric powder negatively influnced on some farinograph parameters (water absorption, arrival time, and dough development time and dough stability) and extensograph parameters (elasticity, extensiblity, proportional number and energy of dough). Staling rate results showed that there was gradual decrease in all fortified pan bread samples for freshness up to 48 hours of storage in compared with those of control sample, also, an observed decrease in staling rate after 48 hours of storage of all pan bread. Sensory evaluation results indicated that there was an enhancment in all nutritional value, the acceptability properties of all pan bread samples.

A low carbohydrate and high fat (LCHF) flour was developed by combining almond flour, desiccated coconut flour, defatted soya flour, dry gluten powder, psyllium husk and skimmed milk powder. Determination of rheological, bread making, nutritional, and staling characteristics of LCHF flour in comparison with wheat flour (WF) was studied. The results showed that LCHF flour had lower amylograph pasting temperature (31.6 °C), peak viscosity (200 BU), farinograph dough stability (0.8 min), and bread volume (315 ml) compared to WF (61.0 °C; 782 BU; 8.7 min; and 525 ml) respectively. The use of additive mixes such as fungal alpha-amylase, sodium stearoyl-2-lactylate and xanthan gum, improved the volume and texture of the LCHF bread. Scanning electron microscope images showed little or no presence of starch granules in LCHF dough and bread. Differential scanning calorimetry studies indicated that, during storage (1–5 days), the enthalpy for gelatinization of endotherm starch increased (0.71–3.40 j/g) in WF bread, however, in LCHF bread this increase was lesser (0.53 to 2.2 j/g) indicating slower staling rate in LCHF bread. The LCHF bread showed lower carbohydrate (13.7%), in-vitro starch digestibility (17.3%) and staling rate, higher protein (22.51%), fat (11.01%), and medium-chain fatty acids than WF bread (51.9%; 38.2%; 12.57%; 3.78%) respectively. The results showed that the developed product would be beneficial for people suffering from diabetics and obesity.

Seaweeds are considered a promising ingredient to use in developing novel food products, due to their nutritional composition and richness in bioactive compounds. The aim of this work is to investigate the effect of four seaweeds (Chlorella vulgaris CH, Laminaria ochroleuca KO, Ulva spp. SL, Arthrospira platensis SP) enrichment (1%, 2.5%, 4%, flour basis) on technological performance and nutraceutical prospective of soft wheat bread. To do this, dough rheological properties measured by means of farinograph and consistograph parameters, baking response (loaf volume, colour, and porosity), and nutraceutical potential of bread (total soluble phenolic compounds, pigments, and antioxidant activity) were evaluated. Algae addition significantly decreased water absorption and development time, except to SL, and increased stability up to 2.5%, and tenacity for KO. In terms of bread properties, the specific volume was positively affected by SP addition, while negatively by KO enrichment; the porosity enhanced especially for SP and CH. Then, bread crumbs and crusts showed a darker and greener colour, especially for green algae. All seaweeds enriched breads showed significant higher phenolic compounds, chlorophylls a and b, and yellow pigment. At last, SP, SL, and CH at 4% level pointed out the highest antioxidant capacity. Our results suggested that the four algal biomasses could be a suitable ingredient in bread making, also in a perspective of a healthier and sustainable diet.

The impact of cottonii (COT, Kappaphycus alvarezii) and spinosum (SPI, Eucheuma denticulatum) flour (1–10% w/w) on rheological properties of wheat (WHE) and quality of bread was investigated. Wheat-COT and WHE-SPI had higher water absorption capacities, dough development times, dough stabilities and farinograph quality numbers than WHE dough. Extensograms of composite dough were largely similar to those of WHE at the same incubation times. Dough energy decreased whereas elasticity ratio (ratio of maximum resistance to extensibility) increased when incubation time was increased from 45 to 135 min. Wheat-COT and WHE-SPI had lower pasting temperatures but higher peak, final, breakdown and setback viscosities than WHE flour. Specific volume of bread containing COT (5% w/w) or SPI (7.5% w/w) was not different (p > 0.05) from that of WHE bread. Crumb texture properties of these composite breads were also largely similar to those of WHE bread. The physical properties of WHE dough and bread were influenced by gluten, whereas those of WHE-COT and WHE-SPI were influenced by gluten in addition to κ-carrageenan in COT and ι-carrageenan in SPI. Protein, ash and dietary fibre contents increased (p

The effect of partial replacement of wheat flour (72% extraction) by different levels (3%, 6%, 9%, and 12%) of sugar beet pulp (SBP) on rheological properties of the dough and quality characteristics of the flat bread produced were investigated. The results showed that SBP contained 7.61% moisture, 6.04% ash, 10.50 Crude protein, 17.55% Crude fiber, 0.53% fat, and 57.77% total carbohydrates. The rheological properties (Farinograph and Extensograph) of the dough were tested. The addition of SBP to wheat flour increased water absorption, mixing time, development time, dough weakening, and decreased dough stability. The addition of SBP also caused an increase in dough resistance to extensibility, proportional number, and a decrease in dough extensibility. On the other hand, the results indicated that values A.W.R.C. decreased as storage periods were increased, but the addition of SBP led to increase in the bread's freshness and reduce the decreasing rate during storage periods. Also, the blend of SBP with wheat flour in the bread decreased the acceptance of its sensory properties by the human members. it can be concluded that it is possible to produce acceptable flat bread fortified with up to 6% of SBP. Finally, the addition of SBP to wheat flour improved rheological properties of dough and improved flat bread quality.

The aim of this study was to assess the potential of different seed flours for cake making and to determine the effect of substitution of wheat with the seed flours on dough rheology and shelf life of the cakes. Composite flours were produced by substituting wheat flour with graded levels (5%, 10%, and 15%) of apricot seed flour (ASF), sour cherry seed flour (CSF), pomegranate seed flour (POSF), and pumpkin seed flour (PUSF). Farinograph was used to determine the effect of seed flour substitution on techno-functional attributes of wheat flour. Cake batter samples were characterized in terms of pH, density, viscosity, and volume of cakes. The shelf life of cake samples was monitored using quality parameters such as moisture, water activity, hardness, and elasticity. Correlation between farinograph characteristics and cake properties were also analyzed. Farinograph characteristics showed that dough prepared with seed flours have higher stability with lower softening degrees. pH and density of batter were not significantly (p > 0.05) affected, while viscosity varied significantly (p 0.05) change. Throughout the storage period, water activity and moisture loss of cakes substituted with the seed flours did not differ significantly (p > 0.05) from the control (100% wheat cake). Texture analysis showed that softer cakes were produced with seed flour substitutions especially when CSF was used. The increase in firmness and elasticity loss was lower in substituted cakes compared to control. The results could have important implications for the valorization of seed flours to produce functional baked products with high protein content.

The core objective of current research was determined to nutritional and bioactive profile of maize bran (MB)‐enriched flour in relation to its end‐use product quality. Furthermore, rheological properties of MB‐enriched flour at different levels (5%, 10%, and 15%) were explicated through farinograph and mixograph. Moreover, bread was prepared with the addition of MB‐enriched flour and was characterized for nutritional and textural properties. Results showed that MB‐enriched flour having high water absorption and water retaining potential up to 4%–7% as compared to wheat flour (WF). Moreover, dough height gradually decreased with the addition of MB due to water‐binding ability of bran which causes a decrease in gas retention during fermentation. This resulted in bread volume decrease (4%–7%) as compared to WF. Furthermore, the moisture content and hardness increased with the addition of MB. The water activity of bread slightly increased with the addition of maize bran after 4‐day storage. Conclusively, MB‐enriched flour improved nutritional, textural, and sensorial properties of final product., Maize bran‐enriched flour is rich source of nutritional and bioactive components. Maize bran‐enriched flour bread has high dietary fibers than wheat flour bread. MB‐enriched flour bread explicated high score of sensorial overall acceptability.

The chemical composition of 4 spring wheat species was analyzed: einkorn (Triticum monococcum) (local cv.), emmer (Triticum dicoccon) (Lamella cv.), spelt (Triticum spelta) (Wirtas cv.), and common wheat (Triticum aestivum) (Rospuda cv.). Mean emmer and einkorn yield was significantly lower than that of common wheat. The analyses of the wheat grain included the content of total protein, crude ash, crude fat, crude fibre, carbohydrates, phosphorus, potassium, magnesium, calcium, copper, iron, manganese, and zinc. The grains of the tested ancient wheats were richer in protein, lipids, crude fibre, and crude ash than the common wheat grains. The significantly highest levels of crude protein, ether extract, and crude ash were found in einkorn. As the protein concentration in the grain increased, the calcium, magnesium, and potassium levels increased, and the zinc and manganese levels decreased. Genotypic differences between the studied wheats were reflected in the concentrations of the minerals and nutrients, an observation which can be useful in further cross-linkage studies. Dough made from common wheat and spelt flour showed better performance quality classifying it to be used for bread production. In turn, flour from emmer and einkorn wheat may be intended for pastry products, due to short dough development time and constancy as well as high softening.

The aim of the study was to estimate the technological value and chemical composition of new common wheat cultivars. The experimental material consisted of grain and flour obtained from 5 cultivars of common wheat, registered in 2017-2019, donated by Plant Breeding Strzelce - IHAR Group Ltd., Co., and harvested in years 2017-2018. The physical characteristics of the grain were determined: milling yield, falling number, gluten content, Zeleny sedimentation index as well as farinograph analysis and laboratory baking were performed. Furthermore, the content of grain nutrients and dietary fiber was determined. Significant differences between cultivars in terms of technological parameters and chemical composition have been demonstrated. The protein content in the grain was in the range of 13.3-15.2%, and the amount of gluten in the range of 28.6-36.8%. The cultivars were characterized by low alpha-amylase activity with an average falling number value 331s. The average water absorption of flour was 62.1%, and the volume of obtained bread was in the range 318-381cm3. The bread of best quality was obtained from the Wilejka cultivar, that was also the richest source of protein. The average dietary fiber content from two years of research was 10.8%, including 7.7% of non-starch polysaccharides (NSP), of which 5.8% of the insoluble fraction (I-NSP) and 1.9% of the soluble fraction (S-NSP). The richest source of dietary fiber was the spring wheat Alibi. The tested cultivars were characterized by high technological value and very good chemical composition and can be recommended for use in the food industry.

Mealworm (Tenebrio molitor L.) is a type of edible insect rich in protein that has become popular as a protein-alternative ingredient in flour-based products to improve the nutritional properties of baking products. The mealworm powder substitution affected the pasting, farinograph, extensograph properties of wheat flour and the texture, nutritional, and sensory properties of the resulting soda biscuit. The pasting parameters (peak viscosity, trough viscosity, breakdown viscosity, final viscosity, and setback viscosity) and the water absorption decreased with the increased mealworm powder substitution level, which was ascribed to the dilution effect of mealworm powder. The farinograph parameters remained similar up to 15% substitution level. The extensograph results showed that mealworm powder substitution decreased the elastic properties of wheat dough as indicated by the consistently decreased extensibility, stretching energy, and stretching resistance, resulting in a significantly decreased baking expansion ratio of the soda biscuit. The protein, lipid, and dietary fiber content of the biscuits increased accordingly with the increased mealworm powder substitution level. The protein content of the soda biscuit was gradually increased from 9.13/100 g for the control (M0) to 16.0/100 g for that supplemented with 20% mealworm powder (M20), accompanied with the significantly increased essential amino acid content. Meanwhile, the fat and dietary fiber content of M20 exhibited 20.5 and 21.7% increase compared to those of M0. The score of the sensory attributes showed no significant difference up to 15% substitution level. The results demonstrated the 15% mealworm powder substitution level would not significantly affect the farinograph property, microstructure of wheat dough, and sensory acceptability.

The present study designed to establish the diosgenin profile from eleven different Indian varieties of fenugreek, and subsequently develop powder from the best stage and variety to prepare diosgenin fortified bread. The seeds, sprouts and leaves of different fenugreek varieties were analyzed for the diosgenin using HPLC. The content of phenolics and flavonoids also estimated and assessed for its antioxidant capacity using phosphomolybdate, DPPH and FRAP. Among eleven varieties screened for diosgenin and the other compounds, tender leaf of Kasuri methi (KS) variety showed the highest content of diosgenin (466.89 ± 0.32 mg/100 g FW), phenolics (58.54 ± 2.70 mg/100 g FW) and flavonoids (1104.16 ± 43.70 mg/100 g FW) followed by Pusa Early Bunching (PEB) (444.18 ± 0.36 mg/100 g FW) and Early Bunching (EB) (409.45 ± 0.42 mg/100 g FW). Among three stages, seeds found to be a better total antioxidant, DPPH scavenging, and reducing ability. Further, based on the results, bread fortified with 1.5% KS leaf powder is found to be optimal which also has significant diosgenin content (268.91 mg/100 g DW). And the effect of KS leaf powder on amylograph and farinograph characteristics of wheat flour and quality characteristics of bread showed promising results of acceptance.

Enzymes are useful to modify wheat proteins to preserve the gas better and to correct the rheological properties of the dough of weak flour and bread. Gluten proteins are highly impacting the quality of various gluten-based products, and transglutaminases (TGs) leading to the strengthening, stability and constancy of the dough as well as the improvement of the volume, texture and storage time of the bread. In the present study, the effect of transglutaminase enzyme on physicochemical and rheological properties of 18% wheat flour was examined as well as polymerization were achieved at the optimum mixing time. The use of transglutaminase (TG) has grown in popularity as they promote specific cross-linking between residues of glutamine and lysine in proteins and significantly increased the dough water absorption compared to the control sample. The results of bread staling evaluation by a instrumental or by instron method showed that the required amount of compression of bread was significantly lower than other treatments during the third and fifth days (P

Breadmaking quality of wheat flour (Triticum aestivum L.) depends not only on the genotype but also on the availability of nitrogen, and wheat protein composition is important for understanding the biochemical basis of wheat quality. The objective of this study was to evaluate the effect of nitrogen availability on flour protein fractions, to analyze their distribution and relationship with bakery quality. We worked with ACA 315 cultivar, where different application rates and timing of nitrogen nutrition were tested. Flour protein fraction composition was quantified following two protocols. Nitrogen application affected glutenin concentration and protein fraction composition favoring polymeric proteins and increasing polymeric/monomeric proteins ratio, however, increase of flour polymeric proteins did not resulted in improved rheological properties. The nitrogen added in this experiment in the differen experiments was not enough to obtain good quality bakery flours. Low protein values were obtained in grain, low gluten concentration and the dough had low W value and high P/L, being very tenacious and no very extensible. Due to low grain protein concentration farinograph parameters could not be interpreted since, under these conditions they are overestimated. These results show that not only genotypic genetic information, should be considered, also gene expression regulation in response to environmental factors, such as nitrogen availability. Therefore, genotype should continue to be studied, both at the level of variation allelic individual and in combination of different alleles of grain reserve proteins. It is also necessary to incorporate in future studies amount and timing of nitrogen application and other nutrients, such us S, in order to obtain better quality bakery flours in La Pampa province.

The study aimed to evaluate the physicochemical and rheological properties of flour samples for six commercial Egyptian bread wheat (two commercial varieties namely Giza-168 and Gemmeiza-11, and four promising lines namely L84, L148, M10, and M34). The sample of M10 which induced/mutated by gamma radiation at dose 350 Gy, showed the best physicochemical and rheological properties, i.e., ash, protein, wet gluten, gluten index, falling number, extraction percentage, and Zeleny value were 0.63, 14.1 %, 36.4 %, 87%, 567 sec., 83.8% and 58 %, respectively. The farinograph parameters water absorption (65.8%), dough development time (11 min) and dough stability (10.8 min) were significantly (P < 0.05) higher in M10 compared to all other samples under study. Furthermore, alveograph parameters showed the highest tenacity (142 mm), dough extensibility (107 mm) and dough deformation energy (499 10-4J). Thus, the promising sample induced via gamma radiation (M10) was the best for parameters in bread making.

Superior bread-making quality is required before breeding lines can be commercially classified. In South Africa, breeding lines together with a quality standard from five environments must be submitted for quality analysis for three consecutive seasons before such lines can be classified for commercial use. Breeders depend on falling number and mixograph analysis to indicate which breeding lines must be selected for submission. Time availability determines whether whole flour or white flour will be used for this quick screening process. During the classification process, the lines have to adhere to 11 primary quality criteria, which include hectolitre mass, falling number, grain and flour protein content, flour yield, flour colour, farinograph water absorption, alveograph stability/distensibility ratio, alveograph dough strength, loaf volume and corrected loaf volume. The aim of this study was to compare flour obtained from three different milling procedures, by using six selected Mixsmart parameters as indicators of the primary classification criteria for commercial cultivar release, to determine whether faster milling procedures such as a hammer mill or Junior Quadrumat mill will give the same results as the currently used Buhler mill. Seed of ten genotypes from two environments was used. There were sufficient correlations between the Mixsmart parameters and primary quality criteria, for selection of the best potential breeding lines, whether whole flour, white flour from the Junior Quadrumat mill or flour from the Buhler mill was used. Linear discriminant analysis confirmed that no differences existed between the three milling procedures for mixograph analysis as indicator of quality.

Farinograph and mixograph-related parameters are key elements in wheat end-products quality. Understanding the genetic control of these traits and the influence of environmental factors such as heat stress, and their interaction are critical for developing cultivars with improved for those traits. To identify QTL for six farinograph and three mixograph traits, two double haploid (DH) populations (Yecora Rojo × Ksu106 and Klasic × Ksu105) were used in experiments conducted at Riyadh and Al Qassim locations under heat stress. Single nucleotide polymorphism (SNP) markers were used to determine the number of QTLs controlling these parameters. The genetic analysis of farinograph and mixograph-related traits showed considerable variation with transgressive segregation regardless of heat stress conditions in both locations. A total of 108 additive QTLs were detected for the six farinograph and three mixograph traits in the Yecora Rojo × Ksu106 population in both locations under heat treatments. These QTLs were distributed over all 21 wheat chromosomes except 3A. Similarly, in Klassic × Ksu105 population, there were an additional 68 QTLs identified over the two locations and were allocated on all chromosomes except 1D, 2A, 6A, and 6D. In population (Yecora Rojo × Ksu106), the QTL on chromosome 7A (Excalibur_c62415_288) showed significant effects for farinograph and mixograph traits (FDDT, FDST, FBD, M × h8, and M × t) under normal and heat stress condition at both locations. Interestingly, several QTLs that are related to farinograph and mixograph traits, which showed stable expression under both locations, were detected on chromosome 7A in population (Klassic × Ksu105). Results from this study show the quantitative nature of the genetic control of the studied traits and constitute a step toward identifying major QTLs that can be sued molecular-marker assisted breeding to develop new improved quality wheat cultivars.

This research aims to study the effect of replacing fat with avocado puree or powder on the sensory, rheological, physical and chemical properties of the cup cake. Results of sensory evaluation of cup cake samples which prepared from avocado puree or powder showed no significant differences at (P

The aim of study to produce high quality, nutritional value, sensory and rheological properties toast bread from doum fruit powder DFP and wheat flour WF. Four toast were prepared; by substituting wheat flour with 0, 10, 20 and 30% by doum fruit powder (DFP). The chemical, caloric value, physical and sensory properties of toast bread were studied. The results showed that addition of DFP to WF at different proportion due to an increase in water absorption (%), dough softening (B.U), dough development (min) and water holding capacity. Meanwhile, extensibility(mm) decreased in all doughs of DFP (10, 20 and 30%). Energy was decreased by addition of DFP at levels of 20 and 30% of DFP were (15 and 20 cm2), respectively. The results showed that increasing the levels of replacement increased ether extract, ash and crude fiber contents in prepared toast bread compared with control. Minerals of the prepared toast bread showed an increased in Ca, K, Mg and Fe while slightly decreased in P and Mn with increasing the proportions of replacement. The sensory evaluation results showed a significantly increase in the taste, odor, crumb grain and crumb texture by increasing the DFP substitution comparing with control. Meanwhile, crust color, appearance and overall acceptability decreased than control.

Chinese steamed bread (CSB) accounts for 30% of the wheat end‐use in China. CSB was studied as a platform for fiber and protein enrichment, employing corn distillers dried grains. Food grade distiller's grain (FDDG) processed from co‐products from the corn ethanol industry was used as the enrichment ingredient. Since CSB uses a lean formula with little or no added sugar or fat, it relies entirely on fermentation and steaming for flavor and texture development. FDDG was used to replace 0%–25% all‐purpose flour (APF) in CSB formulations. Effects of FDDG on dough properties and quality of CSB were evaluated by instrumental (Farinograph, Mixolab, and Texture Analyzer), nutritional, and sensory methods. Protein and dietary fiber contents showed significant increases to 18.8% and 15.3%, respectively, for 100 g of steamed bread (25% FDDG db). Fiber in 100 g of fresh FDDG CSB ranged from 2.8 to 7.7 g. FDDG fortified doughs demonstrated higher water absorption, while dough development time, dough stability, and dough extensibility decreased significantly with partial APF replacement. FDDG contributed to increased hardness and adhesiveness in the CSB. Crumb analysis revealed reduced number of gas cells at higher FDDG substitution. FDDG enrichment reduced brightness (L*) of flour blends and CSB. Rheological and sensory analysis showed an upper level of FDDG substitution of 15% was acceptable without detriment to dough functionality, texture, and taste., This study provides compositional and food functional attributes of Chinese steam bread fortified with a high protein and high fiber ingredient. Distillers dried grains (38% protein and 40% dietary fiber) from corn was developed for food‐grade application and enrichment of steamed bread.

Background Grain milling might be the oldest manufacturing process in the world, and many techniques are currently used in the food industry. The two predominant methods used in wheat milling are stone milling and roller milling. The selected technique significantly influences flour quality, dough rheological properties, and bread characteristics. Choosing the most suitable method is essential; therefore, here we summarise the advantages and disadvantages of each technique and suggest specific improvement strategies. Scope and approach The first aim is to summarise current knowledge regarding the effects of stone milling and roller milling on wheat flour quality, dough rheology, and bread characteristics. The second aim is to propose specific strategies to improve the two techniques. Key Findings and Conclusions This review highlights the importance of selecting the most suitable technique. Stone milling has a few, clear advantages. These include: ease of use and the simplicity of the system; higher concentrations of macroelements, microelements, and polyphenols in flour; increased whole wheat bread volume; and popularity with consumers. Roller milling, on the other hand, also has advantages. These include: greater efficiency and flexibility; less heat generation; and better dough rheological performance. This review has not declared a “winner”, as both techniques have advantages and disadvantages. The optimal milling system is a function of the aim to be achieved, bearing in mind business needs and product demand.

Flat bread is a popular staple food consumed in India prepared from whole wheat. This research is an attempt to add peanut (Arachis hypogaea) flour (10–40%) prepared by processing the peanut meal in wheat flour to enhance bioactive constituents, textural and nutritional properties of the resultant flat bread. Stickiness and spreadability of dough was slightly increased with increasing levels of peanut flour (PF). Flat bread substituted with PF exhibited significantly higher total phenolic content and total flavonoid content, antioxidant activities by scavenging DPPH and ABTS free radicals than control. Farinograph, textural and sensory assessment of flat bread, recommended substitution of 30% PF. Flat bread prepared from this level of PF had superior protein (22.89%), ash (9.34%), fat (3.52%) and mineral content. An enhanced in vitro protein digestibility (85.73%), higher dietary fiber content (8.60%) and lower glycemic index (42.39) were recorded as compared to that of control flat bread. The microstructure of flat bread containing 30% PF showed disrupted gluten matrix with protein aggregates whereas in case of control flat bread aggregates of starch granules overlapping one another were observed. The X-ray diffraction spectra showed V-type polymorphism with one diffraction peak at 2θ = 20.1°, displaying a lower degree of crystallinity.

Einkorn flour, rich in proteins, carotenoids, and other antioxidants, generally has poor breadmaking value. In this research, the composition and technological characteristics of the flours and breads of two elite einkorns (Monlis and ID331) and a bread wheat (Blasco), cropped in four different environments, were evaluated. The einkorns confirmed better flour composition than bread wheat for proteins (on average, 16.5 vs. 10.5 g/100 g), soluble pentosans (1.03 vs. 0.85 g/100 g), and yellow pigment (10.0 vs. 1.0 mg/kg). Technologically, they had better SDS sedimentation values (89 vs. 66 mL), lower farinographic water absorption (52.6 vs. 58.8%), and a similar development time, stability, and degree of softening. Viscoelasticity tests showed lower storage and loss moduli and more prevalent elastic behaviour for Blasco, while rheofermentographic tests showed an anticipated development time (120.8 vs. 175.0 min), higher maximum height (73.0 vs. 63.0 mm), and superior retention coefficient (99.1 vs. 88.7%), but a lower CO2 total (1152 vs. 1713 mL) for einkorn doughs. Einkorn breads were bigger than the control (736 vs. 671 cm3); crumb pores percentage was similar, but medium-size pores were scarcer. Finally, a 52-h shelf-life trial demonstrated that einkorn bread had a softer texture, maintained for a longer time, and a slower retrogradation than the control. Therefore, choice of appropriate varieties and process optimisation allows the production of excellent einkorn breads with a superior nutritional value and longer shelf life.

The introduction of new high-yielding wheat cultivars and the intensification of high year-to-year variability require an additional update of information about environmental effects on main wheat quality parameters lacking for newly released cultivars in Serbia. This study aimed to determine the effect of growing seasons on the technological properties of new Serbian wheat cultivars and examine the relationships among the quality traits in different growing seasons. The experiment was set up in three growing seasons (2016-17, 2017-18, and 2018-19). A total of 13 recently developed wheat cultivars in Serbia and the five most widespread local cultivars were evaluated to compare differences in end-use quality. Also, the influence of climatic conditions on technological quality was examined and relations among them. Modern Serbian cultivars have improved grain yield but lower technological quality than the widespread Serbian cultivars. Changes in farinograph resistance and degree of softening were related to the differences in growing seasons, cultivars, and their interaction, while growing seasons had the highest effect on bread volume and extensograph parameters energy and ratio resistance, and extensibility variation. Moreover, a strong positive correlation was found between protein content, sedimentation value, wet gluten content, water absorption with extensograph extensibility, and negative correlation with the second parameter of extensograph, resistance ratio, and extensibility. Highlights- The modern wheat cultivars showed improved grain yield but lower technological quality than widespread cultivars.- The growing seasons had the highest effect on bread volume and extensograph properties.- Grain yield was negatively related to protein content and bread volume.

The use of different protein sources in cereal products does not only aim to enrich them with proteins, but also to improve their protein quality, especially concerning the lysine content, the limiting amino acid in wheat flour. As an alternative to enrichment, protein isolates become viable because they provide protein content and quality. However, that the addition of protein sources to wheat flour greatly affects its rheological properties. Thus, the objective of this study was to evaluate the empirical rheology of wheat flour doughs substituted by pea (PPI), soybean (SPI), and whey (WPI) protein isolates, comparing the behavior of these three sources in order to predict the best application. Of all the isolates, PPI seems to have interfered less in the rheological profile of pure flour. WPI caused major changes, while SPI remained intermediate, but closer to PPI. Concentrations of PPI and SPI up to 10% and WPI up to 5% did not greatly modify the viscoelastic profile of the dough, which would allow the use of these mixtures in the production of breads, while higher concentrations would be more suitable for the manufacture of molded biscuits, in which the formation of a protein network is not necessary.

Rheological characteristics, i.e., farinograph and extensograph test in dough, specific-volume, hardness, sensory-properties, and the physicochemical-properties of toast-bread containing four levels (0-15%) of Portulaca oleracea leaf-powder (PLP) based on flour weight were determined. The water absorption and development-time of the dough sample increased with the addition of PLP. The increase in the PLP content in the dough sample from 10% to 15% showed significant differences in dough-stability. The energy and extensibility of dough increased for 5 and 10% and then decreased for 15% PLP substitution levels at dough resting time 45, 90, and 135 minutes after production. The specific-volume decreased and the pressure force reversely increased stepwise by 5 up to 15% dosage. Sensory-evaluation indicated that 10% of PLP in the bread is the most acceptable-level, more enriched-bread variants were less acceptable mainly owing to having less significant colour and sensory indices (p < 0.05), meanwhile dough water-absorption and specific-volume had no significant difference compared to less enriched bread samples (p > 0.05). As expected, the colour changed, too, from light brown (the control) to dark green (for 15% the PLP in bread). The moisture, dietary-fiber, protein, ash, and fat content significantly increased in the toast-bread, reflecting the enhancement levels.

Patients are at risk of malnutrition as a result of their, disease and the treatment. Support and intervention Nutrition is important for those patients. The aim of this study was to formulate and evaluate types of biscuits formed from mixture of oat flour, wheat germ, flaxseed, pomegranate peel and wheat flour with different percentages for supporting nutrition for patients. Methods: by using :oat flour, wheat germ, flaxseed, pomegranate peel and wheat flour and their blends for production of biscuits from functional flour blend suitable for nutritional support for patients. Biscuit made of 100% wheat flour was prepared for control sample. For all chemical composition, starch gelatinization, diffraction scanning colorimetry (DSC), colour attributes and sensory properties of biscuits were studied. Oat flour was added to wheat flour at 10, 20, 30, 40 and 50% level. Results: Farinograph parameters showed that water absorption was increased as the percentage of oat flour increased in wheat flour. Diffraction Scanning Colorimetry and Visco-amylograph parameters were significantly affected. Results also showed that Hunter colour parameters (L*, a* & b*) of biscuits were darker as mixing level of oat flour increased, but sample which contained oat flour, wheat germ, flaxseed and Pomegranate peel had an excellent nutritional values and (good) acceptable characters that made it to be suitable for patients for support their nutritional defects due to the treatments( chemo & radiotherapy) with difficulty in having their nutritional requirements. It could be concluded that: oat flour + wheat germ+ flaxseed + Pomegranate peel could be used with wheat flour to formulate biscuit characterized with its good sensorial properties, higher nutritive value, in addition to their positive effect on the rheological characteristics.

BACKGROUND The effect of polyphenol addition on dough mixing properties and flour functionality was examined using flours from different wheat varieties. RESULTS Both the mixograph and farinograph experiments showed that polyphenol addition affected dough stability and optimum mixing time. These effects were most apparent in hard wheat flour with the addition of catechin. Water absorption was dependent on wheat variety (P

The purpose of this study was to investigate the effects of reconstituted whole wheat flour (WWF) particle size on flour characteristics and northern-type steamed bread (NTSB) quality. In this study, hard white (HW), hard red winter (HRW), and hard red spring (HRS) wheat classes, and four different bran particle size distributions [D(50) values of 53 μm, 74 μm, 105 μm, and 125 μm] were blended at a ratio of 85% refined flour + 15% bran to create reconstituted WWF and make reconstituted WWF NTSB. Farinograph water absorption and water solvent retention capacity (SRC) increased as bran particle size decreased. Flour and dough strength tests such as lactic acid SRC and Farinograph and Mixolab development time and stability did not show any clear trends with bran particle size. HRW WWF tended to be the exception as Farinograph development time and stability generally increased as particle size increased. Resistance to extension increased as bran particle size decreased for HRW WWF and increased as particle size increased for HW and HRS. These differences in WWF dough rheology trends were likely due to differences in gluten characteristics between the classes. The results showed that larger particle sizes (105 μm and 125 μm) were more conducive to achieving desirable whole wheat NTSB specific volume, color, and texture.

Fusarium head blight (FHB) is one of the major threats for wheat production worldwide. It reduces yield, quality, and feeding value of wheat grains. In addition, mycotoxins produced by Fusarium pathogens can have a negative effect on livestock and human health. The aim of this study was to assess changes in technological quality traits and end-use quality of winter wheat varieties after artificial inoculation with Fusarium spp. over three years. Differences in dough development duration and extensibility were measured as the means of relative reductions due to different environments and varieties’ characteristics. Differences in dough softening during kneading were determined as the means of relative increases due to FHB inoculation. In addition, dough had reduced strength, was stickier, and therefore was more difficult to handle, due to a decrease of the average energy value and resistance to extension in FHB-inoculated wheat, compared to naturally infected plants. Dough development time, stability, and resistance usually varied in a similar way, with FHB-resistant varieties showing a good response to FHB inoculation and maintaining good quality. Increasing the level of Fusarium spp. contamination in more FHB-susceptible wheat varieties worsened their technological quality, primarily, the sedimentation value and the gluten index, and hence had a negative effect on the rheological properties.

The objectives of this study were to investigate soft wheat quality traits with fertilizer management practice in southern region of the Huaihe river in Jiangsu province, and to suggest quality selection parameters in soft wheat breeding. Fifteen high quality soft wheat varieties or advanced lines were grown at three environments with the combination of location and year. High-molecular-weight glutenin subunits (HWM-GS) of tested genotypes were identified. Kernel hardness, grain and flour protein content, wet gluten content, ash content, Zeleny sedimentation value, parameters of farinograph, mixograph, and rapid viscocity analysis (RVA), solvent retention capacity (SRC), gluten protein quantification, and cookie quality were investigated. No sample met the national soft wheat quality standard (GB/T 17320-2013, GB/T 17893-1999) for protein content, wet gluten content, and farinograph stability, few samples met the standard for sedimentation value, and all samples exceeded the standard for kernel hardness and farinograph absorption. Kernel hardness, ash content, and RVA parameters were not significantly associated with cookie quality parameters. Zeleny sedimentation value, absorption and stability of farinograph, peak time and right of peak slope of mixograph, water SRC, sodium carbonate SRC, lactic acid SRC, glutenin/gliadin ratio, unextractable polymeric protein (UPP), and %UPP were significantly correlated with cookie diameter, with r = –0.657, –0.601, –0.617, –0.659, –0.676, –0.857, –0.726, –0.616, –0.546, –0.541, and –0.637, respectively ( r ≤ –0.520, P r ≤ –0.652, P

Mixtures of refined wheat flour (RWF) with flours from different sources could impact the functional qualities and shelf life of wheat-based products. Storage stability is one of the most critical factors for tortilla quality. Tortillas made from yam (Dioscorea sp.) wheat composite flours were characterized. RWF was substituted with 5%, 10%, 15%, and 20% of fermented yam flour-brown (FYF) and unfermented yam flour-white (UYF). Farinograph water absorptions of UYF-composite flours (65.5% - 77.1%) were significantly (P < 0.05) higher than FYF-composite flour absorptions (60.5% - 61.5%). During storage, moisture contents of composite flour tortillas increased while the RWF-tortilla decreased. Tortilla from FYF-composite flour exhibited greater strength (3.1 N at day zero on average) compared to UYF-composite tortillas (2.1 N at day zero on average), while UYF-composite flour tortillas had good extensibility and rollability properties. The properties and composition type and ratios of flour blends affected tortilla quality during the storage period. The substitution of RWF with 15% or 20% UYF would be more suitable for making tortilla with improved properties compared to that of FYF.

Physiochemical and rheological properties of local wheat cultivars were studied to determine and develop their relationship to baking quality of white layer cake. The investigation carried out via studying four different wheat cultivars (Adana, Sham 6, Tamooz 2, and Slemani 2), and comparing to a locally produced flour (from Sulaimani Cereal Milling Company) as control. According to physical parameters, the highest value were obtained by Slemani 2, and in terms of falling number control also recorded the highest. In regards to chemical composition (such as; Protein, Fat, Ash, and Moisture) the greatest values were reported by (Tamooz 2, Sham 6, Adana, and Slemani 2) respectively. Nevertheless, rheological characteristics for farinograph in terms of (water absorption, developing time, stability, and tolerance mixing index), the highest values were achieved by (Tamooz 2, Adana, Control, and Sham 6), respectively. While for amylograph characteristics the highest values were recorded in Slemani 2, and Control in terms of (pasting temperature, and peak viscosity) respectively. The gluten yield parameters tested for gluten index, and dry gluten in which the results obtained for Control, and Sham 6 were the greatest. For physical characteristics of the white layer cake the Control achieved the highest value for volume index, symmetry index, and specific volume. Finally, the Control and Adana have scored the highest values for sensory evaluation. In general, the best white layer cake quality was obtained from the Control, Adana, and Sham 6, hence the protein quality and quantity have great influence on the end product.

The physicochemical and cooking properties of wheat starch isolated from alkaline yellow dough treated with sodium carbonate (Na2CO3; 0–3.2 g/100 g) were investigated. With increasing Na2CO3 addition, swelling power increased from 7.28 to 10.70 g/g. X-ray diffraction showed no changes in crystalline patterns while the relative crystallinity decreased from 30.11% to 23.13%. Differential scanning calorimetry results suggested that alkaline salt shifted the gelatinization peak of starch to higher temperatures. The values of pasting viscosity and pasting temperature in alkali-treated starch increased and decreased, respectively. Farinograph results revealed the strengthened structure of dough with alkali-treated starch that was manifested by an increase in the dough development time and dough stability time. Cooking loss and rehydration values of noodles prepared from alkali-treated starch increased by 42% and 36%, respectively. The results suggested that Na2CO3 affected starch crystalline structure, swelling power, gelatinization, pasting properties, starch-gluten interactions and cooking characteristics of noodle products.

The grain industry occupies an important position domestically and globally as it has a major role in the daily diet of all individuals. Therefore,this study aimed to improve and change rheological properteies of wheat flour (type Sakha 94) using some enzymes as well as investigate the effect of adding these enzymes on making of balady bread with sensory evaluation of final product.The results of this study showed crude protein content was 12.98 and 11.98% for Egyptian wheat (Sakha 94) and wheat flour (72% ext.), respectively. Also, the results showed that the whole wheat grain and wheat flour contain 27.2 and 30.4% wet gluten, respectively. Gluten index recorded 73.32 and 84.6%. Also, results showed increasing dry gluten in wheat flour to be 12.6%. The rheological tests is carried out using the farinograph, extensograph, mixolab and alveograph. All characteristics were improved especially with the blend coded (X1) which consists of 10 ppm glucose oxidase and 3 ppm α-amylase, whereas the dough giving the highest value of stability andresistance after adding this enzymes. The results of sensory evaluation of balady bread indicated that this mixture was the best addition used. Thus, It could be concluded that the addition of enzymes remained as good Organoleptic attributes for balady bread with the third day as well as fifth day compared with control sample and all treatments.
