The purpose of the study was to create the coating with the synergetic essential oils mix for bread to replace the usual plastic package with an environmentally friendly and mold resistant option. Different mixtures efficiency was analyzed and compared. 3 pairs of essential oils containing citral-eugenol, citral-thymol and carvacrol-thymol were selected for the experiment part. 3 types of bread were compared and the most susceptible to fungi was selected for further studies. 3 coatings were made of divergent essential oils blend, containing the required concentration of constituent, and soy wax. These coatings were applied to the carton’s box inner surface for antifungal properties and reduced air permeability. Samples of bread were kept in 4 packages: an original plastic bag, paper box with one wall coating, all inner surface coating and without any coating. These packages were compared to each other by lost weight amount and textural parameters before and after storing. This was done to find out that the coating helps to retain moisture in the product. 2 layers of the coating were applied for the last part of the experiment where citral-thymol and carvacrol-thymol coatings were effective to inhibit mold activity. Coating without bending edges covered, accurate synergistic concentrations and sensory analysis performance should be considered as an opportunity for future research., Tyrimo tikslas – sukurti dangą su sinergetiniu eterinių aliejų mišiniu duonai, kuri pakeistų įprastą plastikinę pakuotę ekologiška ir atsparią pelėsiams. Išanalizuotas ir palygintas skirtingų mišinių efektyvumas. Eksperimentinei daliai buvo atrinktos trys poros eterinių aliejų, kurių sudėtyje yra citralio-eugenolio, citral-timolio ir karvakrolio-timolio. Tarpusavyje buvo palygintos trys duonos rūšys ir labiausiai imli pelėsiams atrinkta tolesniems tyrimams. Trys dangos buvo pagamintos iš skirtingų eterinių aliejų mišinio, turinčio reikiamos koncentracijos sudedamųjų dalių, ir sojų vaško. Dangos buvo užteptos ant kartoninės dėžutės vidinio paviršiaus, siekiant suteikti priešpelėsinių savybių ir sumažinti oro pralaidumą. Duonos mėginiai buvo laikyti keturiose pakuotėse: originaliame pastiko maišelyje, popierinėje dėžutėje, padengtoje danga ant vienos sienos, vidinio paviršiaus ir be dangos. Šios pakuotės buvo palygintos tarpusavyje pagal prarastą svorį ir tekstūros parametrus prieš ir po laikymo. Buvo išsiaiškinta, kad danga padeda išlaikyti drėgmę gaminyje. Paskutinėje tyrimo dalyje dėžutės buvo padengtos dviem sluoksniais, kuriame citralio-timolio ir karvakrolio-timolio dangos veiksmingai slopino pelėsių aktyvumą. Dangos padengimas išvengiant lenkimo briaunų, tikslių sinergetinių koncentracijų užtikrinimas ir juslinės analizės atlikimas turėtų būti apsvarstyti metodai kaip ateities tyrimų galimybėmis.

Remains of ancient dishes can contribute significantly to the knowledge of past dietary habits, adding cuisine as the “missing link” between crop and consumption. Charred and fragmented archaeological remains of processed cereal preparations, while long having been neglected as a find category, bear large potential for analysis just as entire archaeological “bread loaves” do. The submitted work aims at providing a set of methods suitable for the analysis and interpretation of such finds. After the introduction to the theoretical framework of the research questions, basic processes in food transformation are laid out with a particular focus on their consequences for the raw material’s tissue and cell structures. Likewise, major factors affecting the deposition, preservation, and recovery of cereal-based foodstuffs are discussed, particularly highlighting the destructive potential of flotation. The historical overview of the field of ancient bread research together with its consecutive chapter gives an evaluation of previous analytical approaches and a methodological “state of the art” as suggested by the applicant, pointing out possibilities and limitations encountered in the identification and quantification of ingredients and in the observation of possible traces of food transformation processes. The thesis concludes with highlighting possible strategies for finding answers to the initial questions by giving suggestions for modelling chaînes opératoires of archaeological food remains, and for the construction of comprehensive typologies within this complex find category.

- Abstract
Background/objectives: Gluten-free diet is the lifelong therapy for patients with coeliac disease. A wide range of gluten-free products (GFP) is available, which mimics the characteristics of their gluten-containing counterparts (GCC). The aim of this study was to compare the macronutrient and dietary fibre composition of GFP and GCC currently available in Spain., Subjects/methods: A cross-sectional study analysing the nutritional differences between 621 GFP and 600 GCC based on labelling information was conducted. Food items were categorized in one of 14 food groups. The first six ingredients were noted for each food item. A linear regression model was used to explain differences in nutritional composition between GFP and GCC and three independent models were created for bread, pasta and biscuits., Results: Results showed that GCC had higher protein content than GFP, especially in flour, bread, pasta and pizza. Bread had higher total and saturated fat contents in the GFP in which palm oil was the main fat used. Flours and starchy ingredients used in GFP formulation were mainly rice and corn flours and corn starch, and palm oil was the most commonly used fat., Conclusions: In conclusion, GFP cannot currently be considered as equivalent substitutes for their GCC. The reformulation of the GFP with more healthy ingredients and ingredients is encouraged, using a healthy oil, pseudocereals and whole flour.

How to avoid the "Jesus multiplying bread and fish" myth and "Münchausen baron bootstrap" legend in individual bibliometric indices: a simple bimedian method applied to Italian ASPA academic members Dear Editor in Chief, Over a decade ago we assessed the status of the bibliographic indicators of ASPA members (Pulina and Francesconi [10]) and since then much water has passed under the bridge of bibliometric science. Based on the weak or null correlation amongst the indicators above discussed, I have developed some bimedian graphs that can help to discriminate high shared authorship and high self-citation ratio as the worse position in the bibliometric space of the scientific careers of academic ASPA members. Conclusions The ASPA community exhibits a good scientific performance with high values of the main bibliometric indicators, obviously greater for the older compared to the younger scientists, with a limited number of co-authors per paper and a low degree of self-citations.

Summary Efficient phosphate (Pi) uptake and utilisation are essential for promoting crop yield. However, the underlying molecular mechanism is still poorly understood in complex crop species such as hexaploid wheat. Here we report that TaPHT1;9‐4B and its transcriptional regulator TaMYB4‐7D function in Pi acquisition, translocation and plant growth in bread wheat.TaPHT1;9‐4B, a high‐affinity Pi transporter highly upregulated in roots by Pi deficiency, was identified using quantitative proteomics. Disruption of TaPHT1;9‐4B function by BSMV‐VIGS or CRISPR editing impaired wheat tolerance to Pi deprivation, whereas transgenic expression of TaPHT1;9‐4B in rice improved Pi uptake and plant growth. Using yeast‐one‐hybrid assay, we isolated TaMYB4‐7D, a R2R3 MYB transcription factor that could activate TaPHT1;9‐4B expression by binding to its promoter. Silencing TaMYB4‐7D decreased TaPHT1;9‐4B expression, Pi uptake and plant growth.Four promoter haplotypes were identified for TaPHT1;9‐4B, with Hap3 showing significant positive associations with TaPHT1;9‐4B transcript level, growth performance and phosphorus (P) content in wheat plants. A functional marker was therefore developed for tagging Hap3.Collectively, our data shed new light on the molecular mechanism controlling Pi acquisition and utilisation in bread wheat. TaPHT1;9‐4B and TaMYB4‐7D may aid further research towards the development of P efficient crop cultivars.

Phenolic compounds of breads added with turmeric at different concentrations (A: 0, B: 1.25, C: 2.5, D: 5 and E:10%) and radiated by UV-C (I. 0, II. 15, III. 30 and IV. 60 s), have been evaluated by HPLC (High-performance liquid chromatography). It is shown that: (i) UV-C radiation modifies the content of phenolic compounds as a function of the percentage of addition of turmeric and the exposure time. There were significant differences (ρ ≤ 0.05) in the concentration of phenolic acids of the turmeric bread (TB): 0 s (sinapic, chlorogenic, protocatechuic), 15 s (chlorogenic, ferulic, protocatechuic, p-hydroxybenzoic, gallic), 30 s (chlorogenic and gallic) and 60 s (chlorogenic). (ii) In TB without radiation appeared, the sinapic, beta resorcylic, syringic and ferulic acids. In the radiation of bread at 15 s, the phenolic acids chlorogenic, ferulic, protocatechuic, p-hydroxybenzoic, gallic, had the highest concentration in the breads added with turmeric at 10% (0.02 μg mL−1), 10% (0.38 μg mL−1), 1.25, 2.5, 5% (0.39 μg mL−1), 10% (1.06 μg mL −1) and 0% (1.10 μg mL−1). (iii) There was a degradation of phenolic acids due to UV-C radiation at 30 and 60 s. At 15 s radiation, sinapic, beta resorcylic, syringic and ferulic acids were not detected in turmeric breads from breads added with turmeric at (1.25, 1.25, 0 and 0%). In radiation at 60 s, beta resorcylic, syringic and ferulic acids were not detected in any bread added with turmeric. In addition, measurements of proximate chemistry, color, sensory analysis, and number of fungal colonies were performed. It is important to mention that the sanitary quality is improved by both UV-C radiation and turmeric. However, the highest results in sanitary quality improvement were due to turmeric.

paper packaging ,bread ,essential oil ,antifungal - Abstract
One of the main concerns in the world is health. The expansion of the food industry has also led to an increase in human morbidity. Therefore, nutrients, especially food additives, started to be more closely controlled after the emergence of scientifically proven threats. Even though these substances are strictly observed to ensure appropriate quantities and materials are used, consumer opinion is still negative towards them. Another crucial problem is the environment. Plastic waste generated in greater vast each year is accumulating and taking more and more space not only on land but also in water and even air. This is because plastic is cheap, strong and quickly made material leading to being the main type of packaging nowadays and creating this loophole situation. By combining naturally occurring substances, new packaging can be created to have the needed qualities. The purpose of the study was to create the coating with the synergetic essential oils mix for bread to replace the usual plastic package with an environmentally friendly and mould-resistant option.

The purpose of this paper is to evaluate from a nutritional, phytochemical, and rheological point of view different varieties/lines of oats cultivated in Romania. In this sense, the proximate composition (proteins, lipids, mineral substances, starch, and carbohydrates), the total polyphenols content (TPC) of individual polyphenols and macro and microelements of 20 oat varieties/lines were determined. In order to evaluate the potential for use in the flour industry (pasta, bread, and biscuits)., a variety of oats with optimal nutritional properties and active principles was used to obtain oat/wheat composite flours in different proportions (10–30% oat flour) and subjected to rheological analysis using the Chopin Mixolab test (Chopin Technologies, Paris, France) The results showed a protein content between 14.36–17.08%, lipid content between 6.01–9.03%, starch between 44.13–52.95%, total mineral substances between 0.93–1.65%, carbohydrates between 65.16–69.32% and energy value between 389.81–409.86 kcal/100 g. The TPC content varied between 614.76–1244.58 µgGAE/g, and the average values of individual polyphenols were between 1.87 μg/g (rosmarinic acid) and 28.18 μg/g (gallic acid). Regarding the macroelements content, potassium (K) was the major element (203.19 μg/g), followed by calcium (Ca) (181.71 μg/g) and magnesium (Mg) (105.79 μg/g). The level of microelements varied between 3.02 μg/g for nickel (Ni) and 60.25 μg/g for iron (Fe). Multivariate data analysis PCA was used to correlate the obtained data. The rheological analysis using the MIXOLAB system proved that, from the point of view of technological properties, composite flours from a mixture of 10–30% oat and wheat flour are the best for obtaining biscuit dough, compared to pasta or pan bread. Following the study and based on nutritional, phytochemical and rheological results, line 2511 was selected as optimal for use in obtaining hypoglycemic flour foods for people with diabetes.

BAKED products ,MANUFACTURING processes ,BREAD ,NUTRITIONAL value ,LENTILS ,RAW materials - Abstract
Bakery products, especially bread, exist in many homes worldwide. One of the main reasons for its high consumption is that the main raw material is wheat, a cereal that can adapt to a wide variety of soils and climates. However, the nutritional quality of this raw material decreases during its industrial processing, decreasing the value of fibers, proteins, and minerals. Therefore, bread has become a product of high interest to increase its nutritional value. Due to the high consumption of bread, this paper provides a general description of the physicochemical and rheological changes of the dough, as well as the sensory properties of bread by incorporating alternative flours such as beans, lentils, and soy (among others). The reviewed data show that alternative flours can improve fiber, macro, and micronutrient content. The high fiber content reduces the quality of the texture of the products. However, new processing steps or cooking protocols, namely flour proportions, temperature, cooking, and fermentation time, can allow adjusting production variables and optimization to potentially overcome the decrease in sensory quality and preserve consumer acceptance.

The goal of this research was to evaluate a polymeric system, including biopolymers, as a multi-component material coating on paperboard for bread. The main aim of the research was to create a humidity-controlling packaging material. This means that the packaging material should contain filler which will absorb water or water vapour from the bread. The ideal packaging should have high barrier qualities against water vapour, enabling the possible release of water from the product (to maintain proper humidity inside the packaging). The preliminary storage tests made of the bread confirmed that the freshness of a product kept in a climatic chamber in RH = 70% was the highest. To summarise, the obtained packaging should maintain the required humidity (in the case of bread, the optimal humidity is 70%) within the packaging to keep the bread fresh after more than 72 h of storage. A "sandwich" form of (multilayer) packaging was indicated as a solution to this problem. The main objective of this packaging was to obtain two paper layers and one starch layer to increase water absorption from the bread. It was also important to obtain a thin, external hydrophobic layer to decrease the water vapour transmission rate of the packaging (WVTR). A number of ''sandwich" packaging types were prepared, consisting of two sheets of paper with an external aquaseal coating and an internal starch coating (with a NaCl filler). The covered ''sandwich" papers were then used to create packaging that could be used for the bread storage tests. The study results confirmed that the bread stored for 72 h in the "sandwich" packaging was found to be fresher than the same product stored in commercial paper packaging. [ABSTRACT FROM AUTHOR]

According to the US Department of Energy, succinic acid (SA) is a top platform chemical that can be produced from biomass. Bread waste, which has high starch content, is the second most wasted food in the UK and can serve as a potential low cost feedstock for the production of SA. This work evaluates the environmental performance of a proposed biorefinery concept for SA production by fermentation of waste bread using a cradle-to-factory gate life cycle assessment approach. The performance was assessed in terms of greenhouse gas (GHG) emissions and non-renewable energy use (NREU). Waste bread fermentation demonstrated a better environmental profile compared to the fossil-based system, however, GHG emissions were about 50% higher as compared to processes using other biomass feedstocks such as corn wet mill or sorghum grains. NREU for fermentative SA production using waste bread was significantly lower (~ 46%) than fossil-based system and about the same as that of established biomass-based processes, thus proving the great potential of waste bread as a valuable feedstock for bioproduction of useful chemicals. The results show that steam and heating oil used in the process were the biggest contributors to the NREU and GHG emissions. Sensitivity analyses highlighted the importance of the solid biomass waste generated in the process which can potentially be used as fish feed. The LCA analysis can be used for targeted optimization of SA production from bread waste, thereby enabling the utilization of an otherwise waste stream and leading to the establishment of a circular economy.

Introduction: Bread is an unavoidable food ingredient in Iranian meals. Given the relationship between salt and baking soda and several diseases, this study aimed to investigate the role of bread and its effect on increasing additives (salt and baking soda) and comparing them to standards. Methods: In this cross-sectional study, all bakeries (95 bakeries) of Garmsar county were selected and sampled from consumed bread (Taftoon; 125, Barbari; 168, Lavash; 48 and, Sangak; 22 samples) and were sent to the Food and Drug Laboratory. The samples were tested according to the National Standards of Iran (No. 2628) method. Descriptive statistics and dispersion, Skewness and Kurtosis, and Spearman correlation were used to evaluate the results. The outcomes of the measures were analyzed using Excel and SPSS software version 22). Results: Comparison of the results of this study with Iranian standards showed that 16.3 and 66.7% of all bread samples, respectively, had the amount of salt and pH in the range of national standards. Barbari had the highest mean salt intake (1.47 ± 0.37), and Lavash had the highest mean pH (6.13 ± 0.36). Significant and reverse correlation was observed between salt intake and pH in Barbari (p = 0.041, r = -0.158) and lavash (p = 0.022, r = - 0.329) samples. The results also showed that the type of additive to increase yeast activity was different according to the type of bread. Conclusions: Bread can play a significant role in increasing the intake of salt and baking soda daily. As a result, bread is a potential source of these additives, and it is recommended that the amount of these substances be controlled to prevent a variety of diseases associated with salt and baking soda.

Crop height (Ht), heading date (Hd), and grain yield (GY) are inter-related in wheat. Independent manipulation of each is important for adaptation and performance. Validated quantitative trait loci (QTLs) for all three co-locate on chromosome 3A in the Avalon×Cadenza population, with increased Ht, Hd, and GY contributed by Cadenza. We asked if these are linked or pleiotropic effects using recombinant lines, and showed that Ht and Hd effects are independent. The Chinese Spring equivalent to the newly defined Ht interval contained a gene cluster involved in cell wall growth and displaying high levels of differential transcript expression. The Hd locus is larger and rearranged compared with the reference genome, but FT2 (Flowering Locus T2) is of particular interest. The Hd effect acted independently of photoperiod and vernalization, but did exhibit seasonal genotype×environment interaction. Recombinants were phenotyped for GY in replicated field experiments. GY was most associated with Cadenza alleles for later Hd, supporting physiological studies using the same lines proposing that ‘late’ alleles at this locus increase spike fertility and grain number (GN). The work has uncoupled height from heading and yield, and shown that one of very few validated GY QTLs in wheat is probably mediated by phenological variation., There are only three validated wheat yield QTLs. Here, one of them was genetically dissected. This showed that the physiological basis of the yield effect is likely to be phenological.

The topic of this paper is an exploration of Romanian and English proverbs and phraseological expressions from the lexical domains of health and food. In terms of linguistic richness, these lexical units are unique cultural expressions conceptualizing peoples' socio-cultural mentalities, while also contributing to the development of sociolinguistic competence. The paper focuses on using paremiology in foreign language classes and also explores suitable teaching strategies and types of activities that may be adapted according to the level of study and the learners' interests. Therefore, the relevance of specialized language courses - including such terminology - in higher education is an attractive educational tool which has the potential to bring learners from different countries together in intercultural environments. Thanks to the simple manner in which proverbs render deeper cognitive aspects of reality, these are also unique tools of expressing socio-cultural and linguistic specificities, while also enriching the cultural experiences the students share with other learning co-participants.

The objective is to verify if gluten-free (GF) and gluten-containing (G) breads differ in their sodium content and lipid profile. Samples of GF (n = 20) and G (n = 14) sliced white sandwich bread of commercial brands most frequently consumed in Spain were collected. The fatty acid (FA) composition and the contents of sodium, fat, cholesterol and phytosterols were determined. Sodium, fat and cholesterol contents were significantly higher in GF bread. The FA composition also differed, while G breads declared in most instances the use of sunflower oil as fat ingredient and presented a higher polyunsaturated FA percentage; GF breads declared a wide variety of fats and oils as ingredients (coconut, palm, olive, sunflower, etc.) which was reflected in their FA profile. Cholesterol content was higher in GF bread because five samples declared the use of whole egg, while G samples did not include any egg product in their formulas. Phytosterol content was higher in G bread but its variability was greater in GF bread. In conclusion, nutritional quality of GF bread varied depending on the ingredients used and might be lower than that of G bread. However, these differences in composition could be reduced or eliminated through changes in the formulation of GF bread. Moreover, the comparison of the results obtained in our laboratory for fat and salt content with the declared contents on the labels showed a much higher deviation for GF samples and it can be concluded that the quality of the nutritional information declared was lower in GF samples.

Increased dosage of TB1 reduces height and stem internode length in bread wheat without affecting coleoptile length., Regulation of plant height and stem elongation has contributed significantly to improvement of cereal productivity by reducing lodging and improving distribution of assimilates to the inflorescence and grain. In wheat, genetic control of height has been largely contributed by the Reduced height-1 alleles that confer gibberellin insensitivity; the beneficial effects of these alleles are associated with less favourable effects involving seedling emergence, grain quality, and inflorescence architecture that have driven new research investigating genetic variation of stem growth. Here, we show that TEOSINTE BRANCHED1 (TB1) regulates height of wheat, with TB1 being expressed at low levels in nodes of the main culm prior to elongation, and increased dosage of TB1 restricting elongation of stem internodes. The effect of TB1 on stem growth is not accompanied by poor seedling emergence, as transgenic lines with increased activity of TB1 form longer coleoptiles than null transgenic controls. Analysis of height in a multiparent mapping population also showed that allelic variation for TB1 on the B genome influences height, with plants containing the variant TB-B1b allele being taller than those with the wild-type TB-B1a allele. Our results show that TB1 restricts height and stem elongation in wheat, suggesting that variant alleles that alter the expression or function of TB1 could be used as a new source of genetic diversity for optimizing architecture of wheat in breeding programmes.

In order to improve the quality of whole wheat steamed bread, in this paper, stone-ground whole wheat flour with low-temperature and low-speed milling was selected, and the natural pigment of pumpkin flour was utilized to study the effect of the addition of pumpkin flour on the whole wheat flour-wheat flour mixture, and the effects of the addition of whole wheat flour, the addition of pumpkin flour, the addition of yeast, and the fermentation time on the sensory, specific volume, and chromaticity of the whole wheat steamed bread. On this basis, the sensory score was used as the response value, and the Box-Behnken experiment was used to optimize to obtain the optimal formulation of whole wheat steamed bread and the nutritional characteristics of whole wheat steamed bread were analyzed. The results showed that the influence of each factor on the sensory scores of whole wheat steamed bread was in descending order: the amount of whole wheat flour added, the amount of yeast added, and the amount of pumpkin flour added. The optimal formulation of whole wheat steamed bread was 55% wheat flour, 45% whole wheat flour, 10% pumpkin flour, 2% yeast, and fermentation time 40 min. The sensory score of whole wheat steamed bread prepared under this formulation was 97.23, which was similar to the predicted value of 97.81. The moisture content of pumpkin whole wheat steamed bread under the optimal formulation was 44.86%, the polyphenol content was 5.47 mg/g, and the flavonoid content was 2.57 mg/g. The steamed bread under the formulation had a golden color, and prominent aroma, fluffy and tasty, and possessed the unique flavors of pumpkin and whole wheat. It provides a useful reference for the deep processing and comprehensive utilization of pumpkins. [ABSTRACT FROM AUTHOR]

Bakery products are a common medium for fungal growth due to their high-water activity and nutrients availability. The application of lactic acid bacteria (LAB) isolated from wheat bran or other cereals has shown great potential in controlling the growth of spoilage fungi, guarantee quality and prolong the shelf life of bakery products. This study outlines the antifungal, technological, functional and safety properties of autochthonous LAB microbiota isolated from type 0 soft wheat sourdough fermentation. Antifungal activity of 77 LAB belonging to Lactiplantibacillus plantarum and Lacticaseibacillus casei species isolated from spontaneous sourdough fermentation was tested in vitro against 16 spoilage fungi. Our findings demonstrated that the antifungal activity, enzymatic and safety properties of LAB isolates vary strain-dependently. Four LAB isolates (Lp. plantarum A16, A25, B11, and B15) showed the best traits, in particular strong antifungal activity and good capabilities to produce exopolysaccharides from different carbon sources in vitro. Care should be taken when using Lp. plantarum A310 and B18 and Lc. casei A23, as starter cultures, since these isolates exhibited a multiple antibiotic-resistance. Here we showed the promising potential of different LAB isolates as bio-preservative agents and to provide new insights regarding their prospective use as starter cultures to guarantee safety and palatability.

Objective:The objective is to analyse Danish consumers’ attitudes to buying food with reduced salt content.Design:The study is based on a comprehensive store intervention that included 114 stores belonging to the same supermarket chain. Three different salt claims were tested for 8 weeks on six test products within the categories bread, cornflakes and frozen pizzas. Scanner data were supplemented with 134 brief interviews with consumers in nine selected stores.Setting:Stores spread across Denmark.Participants:Consumers who buy food in the stores.Results:Statistical regression analyses of the scanner data indicated that none of the three claims significantly affected demand for any of the test products. The interviews confirmed that many consumers were more focused on other elements of the official dietary advice than reduced salt consumption, such as eating plenty of vegetables, choosing products with whole grains and reducing their intake of sugar and fat.Conclusions:Overall, both the scanner data and the interviews pointed in the same direction, towards the conclusion that salt content is often a secondary factor when Danish consumers make dietary choices.

In this work we explored the potential of several strains of Kazachstania unispora to be used as non-conventional yeasts in sourdough fermentation. Properties such as carbohydrate source utilization, tolerance to different environmental factors and the performance in fermentation were evaluated. The K. unispora strains are characterized by rather restricted substrate utilization: only glucose and fructose supported the growth of the strains. However, the growth in presence of fructose was higher compared to a Saccharomyces cerevisiae commercial strain. Moreover, the inability to ferment maltose can be considered a positive characteristic in sourdoughs, where the yeasts can form a nutritional mutualism with maltose-positive Lactic Acid Bacteria. Tolerance assays showed that K. unispora strains are adapted to a sourdough environment: they were able to grow in conditions of high osmolarity, high acidity and in presence of organic acids, ethanol and salt. Finally, the performance in fermentation was comparable with the S. cerevisiae commercial strain. Moreover, the growth was more efficient, which is an advantage in obtaining the biomass in an industrial scale. Our data show that K. unispora strains have positive properties that should be explored further in bakery sector. Graphic abstract

Efforts to increase global food supply through increased productivity and intensity of cropping are well documented. However, the literature on measurement of food losses and wastage and techniques to reduce them is scanty. This study aimed at providing credible evidence on the levels of food losses and wastage at each node along the entire wheat value chain in Jordan - from farm to fork. The “life cycle of food” approach, along with standard protocols developed in line with international initiatives led by the World Resources Institute (WRI) were used for physical measurements and estimation of losses at each node. Our results show that 34% of the total wheat supply in Jordan (both from local production and imports) is lost or wasted – costing the country about US$105 million per year, which is also associated with high levels of losses in natural resources. We found that postharvest losses are more important in Jordan where, at a level of 12.95%, wastage during consumption by households ranks first. Households reported that 67% of the household food waste was fed to animals. This means Jordan is losing 43% and 48% respectively of total protein and energy for every 1US$ spent on bread that is fed to animals instead of barley. These results call for a concerted effort by individuals, civic societies, NGOs and the government towards awareness raising and measures targeting reduction of wastage, especially during consumption. The Government of Jordan has recently reviewed the subsidy on bread, raising hopes that it will reduce consumption losses.

Objective:The present study aimed to evaluate the effect of mandatory iodine fortification of bread on the iodine status of South Australian populations using newborn thyroid-stimulating hormone (TSH) concentration as a marker.Design:The study used an interrupted time-series design.Setting:TSH data collected between 2005 and 2016 (n 211 033) were extracted from the routine newborn screening programme in South Australia for analysis. Iodine deficiency is indicated when more than 3 % of newborns have TSH > 5 mIU/l.Participants:Newborns were classified into three groups: the pre-fortification group (those born before October 2009); the transition group (born between October 2009 and June 2010); and the post-fortification group (born after June 2010).Results:The percentage of newborns with TSH > 5 mIU/l was 5·1, 6·2 and 4·6 % in the pre-fortification, transition and post-fortification groups, respectively. Based on a segmented regression model, newborns in the post-fortification period had a 10 % lower risk of having TSH > 5 mIU/l than newborns in the pre-fortification group (incidence rate ratio (IRR) = 0·90; 95 % CI 0·87, 0·94), while newborns in the transitional period had a 22 % higher risk of having TSH > 5 mIU/l compared with newborns in the pre-fortification period (IRR = 1·22; 95 % CI 1·13, 1·31).Conclusions:Using TSH as a marker, South Australia would be classified as mild iodine deficiency post-fortification in contrast to iodine sufficiency using median urinary iodine concentration as a population marker. Re-evaluation of the current TSH criteria to define iodine status in populations is warranted in this context.

Shortbread biscuits have become one of the most desirable snacks in all population groups but due to its high fat content it is searching for new solutions of fat reduction such as the use of carbohydrate-based fat mimetics. However, the thermal processing of food containing lipids in the presence of certain carbohydrates can contribute to the formation of toxic compounds or alter its levels. Therefore, the aim of the study was to evaluate the use of inulin and pectin gels as partial fat replacers (10–40%) in classical shortbread biscuits in a view of the changes of 3-monochloropropane-1,2-diol ester (3-MCPDE) and glycidyl ester (GE) levels after baking, and also after a two-months storage. The experiment showed that the amount of inulin gel higher than 10% promoted the endogenous formation of 3-MCPDE probably due to the higher amount of Maillard products formed in the biscuits, but after two months the levels decreased and were comparable with those transferred from shortening. Pectin did not demonstrate such phenomenon, owing to the presence of bound water in gel. Glycidyl esters were partially decomposed during baking and also during storage, particularly in the samples with the addition of pectin gel, which presumably caused by low stability of GE under acidic conditions resulting from the occurrence of galacturonic acid in pectin.

The article presents the results of research on the peculiarities of proofing and baking bakery products using a steam-convection oven for continuous proofing and baking. The aim of the work was to develop recommendations for setting parameters for production of bakery products in the steam-convection oven at continuous proofing of dough pieces and bakery products. For control samples baking the author used a proofing box for final proofing and a convection oven. The analysis of the structural and mechanical properties of crumb was made using device “Strukturometer-1”, and loss of weight after baking was measured using standard methods. Intensity and color uniformity of crust were determined applying an ingenious method using flatbed scanner. Automatic recorder monitored the temperature in the baking chamber and inside the baked dough pieces. To determine the changes in product volume and proportion of the formed crumb during baking process, an original optical method was used. As a result of the research the author determined that there is a dependence of the dynamics of baked dough pieces quality indicators on proofing and baking parameters. It is shown that the main differences are observed during the first baking period. The detected regularities are associated with smooth heating of the steam-convection oven baking chamber and high relative humidity of the medium at the beginning of baking process. When using a steam-convection oven, the crusts had uneven color which is obviously due to condensation of a large amount of moisture on the surface during the initial baking period and, consequently, different rates of heating of individual parts of the crust. By the moment when baking process was over control samples and developed samples had insufficient differences concerning structural, mechanical and physicochemical parameters. It was determined that in case of continuous proofing and baking in steam-convection oven it is necessary to extend the baking process and increase dough humidity compared to traditional baking method.

ObjectiveTo simulate effects of different scenarios of folic acid fortification of food on dietary folate equivalents (DFE) intake in an ethnically diverse sample of pregnant women.DesignA forty-four-item FFQ was used to evaluate dietary intake of the population. DFE intakes were estimated for different scenarios of food fortification with folic acid: (i) voluntary fortification; (ii) increased voluntary fortification; (iii) simulated bread mandatory fortification; and (iv) simulated grains-and-rice mandatory fortification.SettingEthnically and socio-economically diverse cohort of pregnant women in New Zealand.ParticipantsPregnant women (n 5664) whose children were born in 2009–2010.ResultsParticipants identified their ethnicity as European (56·0 %), Asian (14·2 %), Māori (13·2 %), Pacific (12·8 %) or Others (3·8 %). Bread, breakfast cereals and yeast spread were main food sources of DFE in the two voluntary fortification scenarios. However, for Asian women, green leafy vegetables, bread and breakfast cereals were main contributors of DFE in these scenarios. In descending order, proportions of different ethnic groups in the lowest tertile of DFE intake for the four fortification scenarios were: Asian (39–60 %), Others (41–44 %), European (31–37 %), Pacific (23–26 %) and Māori (23–27 %). In comparisons within each ethnic group across scenarios of food fortification with folic acid, differences were observed only with DFE intake higher in the simulated grains-and-rice mandatory fortification v. other scenarios.ConclusionsIf grain and rice fortification with folic acid was mandatory in New Zealand, DFE intakes would be more evenly distributed among pregnant women of different ethnicities, potentially reducing ethnic group differences in risk of lower folate intakes.

- Abstract
Flour products played a vital role in the global diet structure. With the increasing demand for dietary health and food standardization, the staple food of flour products made from coarse grains due to its unique flavor and rich nutrition has become a trend and is favored by consumers. However, the lack of gluten protein in the raw materials prevented the formation of a stable gluten network structure, leading to the deterioration of the quality of flour products. Ultrasonic treatment, as an innovative food processing technology, generated energy during the action of ultrasonic waves that had a positive impact on the texture, organizational structure, or flavor characteristics of food. That was of great significance for improving food production efficiency, improving food processing quality, and extending food shelf life. This article applied ultrasonic technology to the processing of flour products from the perspective of promoting fermentation and improving production efficiency of flour products. The cavitation effect of ultrasound promoted the formation of gluten network structure, improved the rheology properties of dough and the quality of flour products by promoting protein cross-linking, improving the foaming and emulsifying stability of gluten protein, and promoting the growth and reproduction of yeast. All reviewed studies indicate that ultrasound would be a promising technology for producing high-quality surface products under appropriate conditions., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Author(s).

This paper investigates the addition of lecithin‐emulsified black seed oil (BSO) nanoemulsions (LNEO) and whey protein isolate‐stabilized Pickering emulsions (WPEO) to soy protein isolate (SPI)‐based films and their effect on improving the shelf life of bread slices. The half‐life of antioxidant activity, water vapor permeability, biodegradability, density, color difference, and film thickness significantly increased (p <.05) when BSO was added. However, the incorporation of BSO significantly reduced the solubility, tensile strength, strain to break (except for WPEO), and transparency (p <.05) of the samples. The interaction between SPI film and BSO‐loaded nanocarriers, as well as the morphological properties of films, was evaluated using FT‐IR and FE‐SEM. SPI‐based films containing LNEO‐5% and WPEO‐5% were selected based on their mechanical and barrier properties. The effect of films on the shelf life of bread slices was investigated for 17 days of storage. LNEO samples obtained the most acceptable results in the bread in terms of sensory evaluation and color properties. According to the results, bread slices packed in SPI film containing LNEO‐5% showed no signs of mold growth until the 17th day of storage, whereas the sample packed in a low‐density polyethylene bag began to corrupt on the 6th day. This study highlights the potential of BSO‐loaded SPI films as a novel active packaging for the bakery industry. [ABSTRACT FROM AUTHOR]

The paper describes the possibilities of designing breads and pastries produced according to a basic recipe from wheat or wheat-rye flour to improve their nutritional potential. The basic principle is the partial replacement of wheat or rye with non-bakery raw materials, which are valued thanks to the content of beneficial components. In this way, it is possible to create diverse products with the potential for positive effects on consumer health. However, the application of such raw materials affects the technological parameters of composite flours and subsequent intermediates of the production process, and it also changes cost items and, consequently, the production price of the products. Therefore, efforts should be made to find the right balance and recommend procedures and recipes that allow the final product to be prepared with the required quality and an affordable price. In our research, the additions of various non-bakery ingredients were verified, and the presented results show how these ingredients affected the selected rheological properties of the dough, and how these changes in the basic recipe affected the costs of the final product. During the experiments, the following raw materials were added: spelt wheat flour, amaranth flour, flour from selected legumes (common bean, broad bean, chickpea, lentil) and lyophilised homogenized red fruits (elderberry fruits, blackcurrant fruits, black chokeberry, and serviceberry fruits, or in the case of elderberry also flowers). The addition of these non-bakery ingredients, depending on the amount of their addition, changed both the water absorption and the rheological properties of the dough (dough development time, dough stability), or baking loss or bread yield. Non-bakery raw materials increase the financial cost of innovative products, and the question arises as to how willing consumers are to pay extra for such foods with added nutritional value. Nevertheless, we believe that designing and producing modern foods with nutritional benefits to meet the demanding needs of modern consumers has a promising future. [ABSTRACT FROM AUTHOR]

Functional nutrition is a concept of nutritional science for which it has been proven to have special health effects, so the constant innovation of functional products contributes to the development of the modern food industry. The paper examines the influence of the addition of Inulin HPX on the sensory quality of bread in order to obtain a new functional product that can improve the nutrition of the population, as well as the catering offer of the destination. Different proportions of Inulin HPX in the amount of 0%, 7.5% and 15% were used for the production of bread dough, as a substitute for part of the flour in the basic raw materials. The goal of the research was to analyze the impact of the functional component Inulin HPX on the sensory (volume, texture, color, smell and taste) and nutritional properties of bread, as well as the acceptance of the new functional product by consumers through a demand survey in the territory of the city of Kotor, Montenegro. Based on the test results, the bread with the functional component of 7.5% Inulin HPX has the best sensory characteristics and a high level of acceptance by consumers. This pilot study can serve as a basis for the marketing of a new functional product on the market of Montenegro intended for consumers who care about healthy lifestyles. One of the conclusions is that it can be a part of improving the menu of restaurants that promote healthy food, but also catering establishments within the framework of wellness and health tourism in Montenegro.

Summary Awns, bristle‐like structures extending from grass lemmas, provide protection against predators, contribute to photosynthesis and aid in grain dispersal. In wheat, selection of awns with minimal extension, termed awnletted, has occurred during domestication by way of loci that dominantly inhibit awn development, such as Tipped1 (B1), Tipped2 (B2), and Hooded (Hd). Here we identify and characterize the B1 gene. B1 was identified using bulked segregant RNA‐sequencing of an F2 durum wheat population and through deletion mapping of awned bread wheat mutants. Functional characterization was accomplished by gene overexpression while haplotype analyses assessed B1 polymorphisms and genetic variation.Located on chromosome 5A, B1 is a C2H2 zinc finger encoding gene with ethylene‐responsive element binding factor‐associated amphiphilic repression (EAR) motifs. Constitutive overexpression of B1 in awned wheat produced an awnletted phenotype with pleiotropic effects on plant height and fertility. Transcriptome analysis of B1 overexpression plants suggests a role as transcriptional repressor, putatively targeting pathways involved in cell proliferation. Haplotype analysis revealed a conserved B1 coding region with proximal polymorphisms and supported the contention that B1 is mainly responsible for awnletted wheats globally. B1, predominantly responsible for awn inhibition in wheat, encodes a C2H2 zinc finger protein with EAR motifs which putatively functions as a transcriptional repressor.

Context: Considering the importance of bread as a staple food in many countries around the world, including Iran, Objectives: This study aimed to assess the nutritional values (i.e., protein content, fat content, carbohydrates, vitamins, minerals, and antioxidant activity) of quinoa-wheat bread compared to simple wheat bread. Methods: A search was conducted in electronic databases, including PubMed, Scopus, and Web of Science, as well as Google Scholar search engine. After screening the title and full-text of the articles, data were extracted by two independent researchers; a third researcher interfered in case of disagreement. Keywords, including "Chenopodium quinoa", "Quinoa", and "bread", were obtained from the MeSh database and the manuscripts of related articles. All papers written in English language, which were published before March 2022, were selected for this review. Results: Among 159 initially extracted articles, 38 were selected by screening the titles and removing duplicates and irrelevant papers. Eleven articles were finally included in this review. Overall, the results showed significantly higher protein, fat, and fiber content in quinoa-wheat bread compared to simple wheat bread. Conclusions: Based on the results, the addition of quinoa flour could promote the health benefits of bread by increasing the protein, lipid, fiber, and micronutrient contents. It is suggested to optimize the nutritional value of the Iranian's staple food by adding quinoa flour to wheat bread. [ABSTRACT FROM AUTHOR]

Black and green olive pulp was added to wheat bread formulation at different levels (5, 10, 15%) with the aim to improve its nutritional value by enhancing the phenolic content and antioxidant capacity. Additionally, the effects of the fortification with olive pulp on the physical characteristics, staling rate and overall consumer acceptability of the formulated breads were explored. Both olive pulps exhibited significantly higher antioxidant activity than refined wheat flour. Baking imparted an impressive increase in TPC, TFC and antioxidant activity of breads as revealed by comparison of experimental with theoretical values but returned significant differences only in the case of TPC when a two-tailed t-test for paired data was applied. Texture measurements showed a substantial increase in hardness with storage along with decreasing loaf volume and increased density. Hydroxytyrosol was the major phenolic compound of fortified breads followed by tyrosol. Olive pulp could be incorporated in a bread formulation without interfering with the general sensory acceptability.

Starch based gluten-free bread (formulations containing mixture of corn and potato starch with hydrocolloids) are deficient in nutrients and do not contain health promoting compounds. Therefore they could be supplemented with raw materials rich in such components, especially antioxidants. Among them pseudo-cereals, seeds, fruits and vegetables are often applied to this purpose. Potato pulp produced by processing red fleshed (Magenta Love) and purple fleshed (Violetta) varieties could become a new innovative substrate for gluten-free bread enrichment, because of high levels of endogenous polyphenols, namely flavonoids, flavonols, phenolic acids and especially anthocyanins with high antioxidant potential, as well as dietary fiber. Study material consisted of gluten-free bread enriched in the pulp. Dietary fiber, acrylamide content and antioxidant and antiradical potential of the bread were determined. Sensory evaluation included crumb elasticity, porosity and other characteristics, taste and smell. Among all analyzed gluten-free breads, the sample containing 7.5% share of freeze-dried red potato pulp Magenta Love was characterized by high content of phenolic compounds and dietary fiber, pronounced antioxidant activity, low levels of potentially dangerous acrylamide and good physical and sensory characteristics. Therefore such an addition (7.5% Magenta Love) could be recommended for industrial production of gluten-free bread.

- Abstract
A cross-sectional study was applied to investigate the influence of food systems and food environments on food choices and nutrition transition of households in Limpopo province, South Africa. A sample of 429 households was systematically selected using a paper selection draw from three districts. This paper determines the association among food systems, food environments, food choices, and nutritional measurements of the respondents. A validated questionnaire was used. Most of the respondents responsible for food procurement were females (80.4%). There was a significant association ( p < 0.001) between proximity to food stores and dietary diversity of the households. Staple foods such as bread, maize, rice, samp, and mealie rice were available in almost all surveyed households (95.6%). More than half of the households (59.8%) had home gardens in their yards. Almost half of the households (48.4%) had a low Dietary Diversity Score. The study further revealed that 46.0% of households were food secure. Over a third (36.2%) of the respondents were obese, and 32.5% were diabetic. The mean total blood cholesterol was 3.69 ± 0.74 mmol/L. A high percentage of both females (89.6%) and males (91.5%) had normal hemoglobin levels. Almost half of the respondents had normal systolic blood pressure levels (45.6%), and nearly a quarter had high diastolic levels (21.4%). The 25 coping strategies were applied during food shortage periods. Even though the food environments provided both obesogenic and protective foods, the consumption of unhealthy foods was high.
