- Abstract
Summary Porang tubers (Amorphophallus oncophyllus) are one of the Araceae family plants, which naturally contain resistant starch (RS). The RS is able to provide health impacts such as reducing the glycaemic index (GI), preventing the formation of gallstones and cardiovascular disease, and increasing mineral absorption. This research aims to improve the RS and prebiotic properties of porang flour through physical, chemical, enzymatic and microbiological modifications. Research methods include modification with physical treatment of autoclaving‐cooling one and two cycles (AC‐1S and AC‐2S), microwave‐cooling (MWC), heat moisture treatment (HMT), annealing (ANN), chemical treatment with acid hydrolysis (HA), enzymatic treatment with pullulanase debranching (DP) and microbiological treatment with combined heating and cooling fermentation (FAC). The results showed that physical, chemical, enzymatic and fermentation modification techniques increased the characteristics of RS and the prebiotic properties of porang flour. The best modification method for porang flour was obtained in the DP treatment with the morphological characteristics of sharp‐surfaced granules, total starch 39.81%, amylose content 3.73%, amylopectin content 36.08%, reducing sugar content 16.31%, power digestibility 43.81%, very rapidly digestible starch (VRDS) 8.59%, rapidly digestible starch (RDS) 11.08%, slowly digestible starch (SDS) 23.60%, RS 56.73%, resistance to gastric acid 98.60%, lactic acid bacteria (LAB) viability 11.87 log cfu/ml, prebiotic effect 3.07, prebiotic index 2.46 and prebiotic activity 1.77.

BACKGROUND RESULTS CONCLUSION Fern root starch has a high percentage of amylose and has great potential for application in the field of slow‐digesting foods. Clarifying the effect of treatment conditions on fern root starch is key to achieving industrialized production of fern root resistant starch. In the present study, fern root starch was treated by the autoclave‐enzymatic method with pullulanase, glucoamylase and mixed enzyme.The content of resistant starch in fern roots treated with mixed enzyme was the highest (24.07 ± 1.11%), which was approximately 320% times that of the native starch, had the best water‐holding capacity (151.08%), vital transparency and freeze–thaw stability. By contrast, the solubility, swelling and viscosity were lower than natural starch. In addition, mixed enzyme shows a denser structure, and the crystal form changes from C‐type to V‐type, with a high relative crystallinity and significantly enhanced thermal stability.After mixed enzyme combined with autoclave treatment, the content of resistant starch in fern root was greatly increased. The modified starch molecules did not produce new functional groups, which made the crystal structure of starch molecules more compact, and resistance to enzymatic hydrolysis and high temperature thermal stability were significantly enhanced. This provides a positive reference for further in‐depth study of fern root starch, improvement of utilization value, development and innovation of new food health products, and diabetes treatment. © 2024 Society of Chemical Industry.

Resistant starch from plantain (Macho Musa paradisiaca L.) and banana (Roatan Musa sapientum L.) varieties was chemically modified by crosslinking using epichlorohydrin (EPI). These modified starches were subjected to in vitro digestibility studies using the Englyst method to determine the content of rapidly digestible starch (RDS), slowly digestible starch (SDS) and resistant starch (RS). The thermal stability of these crosslinked starches was evaluated by gelatinization and retrogradation analyses, and their enthalpies were determined using differential scanning calorimetry (DSC). Additionally, their functional properties were evaluated. Chemical modification with EPI significantly increased the RS content in both starch varieties compared to that in native starch. The enthalpy and gelatinization temperature decreased in the EPI-modified starches of both varieties, indicating lower thermal stability during the gelatinization process compared to that of native starch. In general, both varieties of crosslinked plantain starch had lower viscosity (0.43 Pa*s) than did native starch (0.58 Pa*s). The results indicates that this starch crosslinked with EPI constitutes an alternative for use in food for people with health problems such as high cholesterol levels or postprandial insulin concentrations.

Summary: The existing literature on resistant starch analysis in Australian foods has predominantly relied on older testing methods. Thus, our study aimed to address this gap by assessing the resistant starch content of selected Australian foods using the validated Association of Analytical Chemists 2002.02 testing method. Forty commonly consumed and available foods were tested in duplicate. The resistant starch content of foods varied from 0 to 13.72 g/100 g. Foods with the highest resistant starch were Hi‐maize flour pancakes, red kidney beans, Lebanese bread, and Cornflakes cereal, which ranged from 2.30 to 13.72 g/100 g, respectively. The lowest resistant starch foods included beetroot, rice crackers, All Bran cereal, and Nutri‐grain cereal, which ranged from 0 to 0.04 g/100 g, respectively. This is the first known Australian study to evaluate the resistant starch content of foods using the AOAC 2002.02 method. This data can be used to assess resistant starch consumption in the Australian population, inform gut microbiome research, and guide clinical practice recommendations for fibre intake.

Microalgal biomass for biofuel production, integration into functional food, and feed supplementation has generated substantial interest worldwide due to its high growth rate, non-competitiveness for agronomic land, ease of cultivation in containments, and presence of several bioactive molecules. In this study, genetic engineering tools were employed to develop transgenic lines of freshwater microalga Chlorella vulgaris with a higher starch content, by up-regulating ADP-glucose pyrophosphorylase (AGPase), which is a rate-limiting enzyme in starch biosynthesis. Expression of the Escherichia coli glgC (AGPase homolog) gene in C. vulgaris led to an increase in total carbohydrate content up to 45.1% (dry cell weight, DCW) in the transgenic line as compared to 34.2% (DCW) in the untransformed control. The starch content improved up to 16% (DCW) in the transgenic alga compared to 10% (DCW) in the control. However, the content of total lipid, carotenoid, and chlorophyll decreased differentially in the transgenic lines. The carbohydrate-rich biomass from the transgenic algal line was used to produce bioethanol via yeast fermentation, which resulted in a higher ethanol yield of 82.82 mg/L as compared to 54.41 mg/L from the untransformed control. The in vitro digestibility of the transgenic algal starch revealed a resistant starch content of up to 7% of total starch. Faster growth of four probiotic bacterial species along with a lowering of the pH of the growth medium indicated transgenic alga to exert a positive prebiotic effect. Taken together, the study documents the utilization of genetically engineered C. vulgaris with enriched carbohydrates as bioethanol feedstock and functional food ingredients. [ABSTRACT FROM AUTHOR]

- Abstract
Background and Objectives: Starch modification using heat‐moisture treatment (HMT) has been proven to influence starch functionality and nutritional properties as it can increase resistant starch content and reduce the glycemic index (GI). This study aims to determine the nutritional and functional properties of infrared (IR)‐ and microwave (MW) heat‐moisture‐treated (HMT) white and red non‐tannin, and red tannin sorghum meals with the aim of further reducing the estimated GI. Findings: All treated meals had significantly (p <.05) lower pasting peak viscosity than the untreated samples, possibly due to aggregate formation observed under the light microscope, restricting the starch from swelling to form a high‐viscosity paste. There was a decrease in the percentage of starch hydrolysis between the sorghum types and a further decrease after HMT treatment. A significant difference was observed in the protein digestibility between the sorghum types, but not between the treatments. Conclusion: HMT with IR and MW further reduced the starch digestibility, possibly because of changes in the starch molecular configuration. Significance and Novelty: This study suggests that the changes in the starch functionality and nutritional properties of the HMT‐treated sorghum meals can potentially be useful in the development of lower‐GI sorghum foods. The results also differentiate the characteristics of sorghum types. [ABSTRACT FROM AUTHOR]

Arabinoxylan (AX) and resistant starch (RS) are essential components of dietary fiber, that affect the nutritional value, health benefits, and end-use quality of wheat. Fully understanding their genetic basis is crucial for enhancing wheat quality through marker-assisted selection or other means. In this study, a genome-wide association study of AX-related traits i.e., total-arabinoxylan (TAX), water-extractable arabinoxylan (WEAX), and water un-extractable arabinoxylan (WUAX) of whole wheat flour (WWF) and refined wheat flour (RWF), as well as RS content was conducted using 205 elite wheat varieties (lines) with a composite map (24,355 SNPs) constructed with 90 K single nucleotide polymorphism (SNP) arrays. The broad-sense heritability (H
2 ) of RS was 48.50%, whereas that of AX-related traits ranged from 55.66 to 77.23%. A total of 115 loci for RS and AX related traits, comprising 322 marker-trait associations (MTAs), were identified on all 21 chromosomes across four environments, explaining 5.52–12.40% of the phenotypic variance. Among them, 19 stable loci were significant in two or more environments, including one for RWF-TAX, six for RWF-WEAX, four for RWF-WUAX, three for WWF-TAX, two for WWF-WUAX, and three for RS. Furthermore, 17 co-located chromosomal regions related to the measured traits were stably detected in multiple environments. These findings may be used for further research and to improve wheat quality in wheat breeding programs. [ABSTRACT FROM AUTHOR]- Published

CHEDDAR cheese ,FAT substitutes ,HYDROCOLLOIDS ,GUAR gum ,DAIRY processing - Abstract
This study aimed to investigate the physiochemical properties, techno-functional attributes, and proteolytic impacts of incorporating different hydrocolloids as fat substitutes in low-fat cheddar cheese. The effects of hydrocolloids (gums) and dietary fiber, both individually and in combination, were studied for the production of low-fat cheddar cheese with the same textural and functional attributes as full-fat cheese. Physicochemical, techno-functional attributes, organic acid, and proteolysis analyses were performed at 0 and 90-day storage intervals. The results of different combinations were compared with positive (4% fat) and negative (2% fat) controls, and it was observed that using fat replacers improved the textural and functional properties of low-fat cheddar cheese. A significant difference was observed in the meltability and flowability of low-fat cheese samples with different analytes. The proteolysis pattern in low-fat cheese also differed from that of its full-fat counterpart. Three treatments were considered the best: T2 (guar gum at 0.45%), T6 (guar gum, inulin, and resistant starch at 33%), and T7 (all analytes at equal concentrations). The findings revealed that hydrocolloids notably improved the texture, meltability, and sensory characteristics of low-fat cheddar cheese. Additionally, SEM images revealed that the microstructure variations can be attributed to changes in the hydrocolloids water retention and fat content. The Pearson correlation coefficient revealed relationships between different functional properties, contributing to understanding how hydrocolloids as fat replacers impact the overall quality of low-fat cheddar cheese. This study offers useful information for the dairy sector to manufacture low-fat cheeses that have enhanced customer acceptance and provide nutritional advantages. [ABSTRACT FROM AUTHOR]

Previous studies have modified rice's resistant starch (RS) content by mutating single and double genes. These mutations include knocking out or reducing the expression of sbe1 or sbe2b genes, as well as overexpressing Wx
a . However, the impact of triple mutant sbe2b/sbe1/OE-Wxa on RS contents remained unknown. Here, we constructed a double mutant with sbe2b/RNAi-sbe1, based on IR36ae with sbe2b, and a triple mutant with sbe2b/RNAi-sbe1/OE-Wxa , based on the double mutant. The results showed that the amylose and RS contents gradually increased with an increase in the number of mutated genes. The triple mutant exhibited the highest amylose and RS contents, with 41.92% and 4.63%, respectively, which were 2- and 5-fold higher than those of the wild type, which had 22.19% and 0.86%, respectively. All three mutants altered chain length and starch composition compared to the wild type. However, there was minimal difference observed among the mutants. The Wxa gene contributed to the improvement of 1000-grain weight and seed-setting rate, in addition to the highest amylose and RS contents. Thus, our study offers valuable insight for breeding rice cultivars with a higher RS content and yields. [ABSTRACT FROM AUTHOR]- Published

Resistant starch (RS) is a fraction of starch not digested and absorbed in the small intestine, and it is fermented by the intestinal microbiota in the colon, thereby influencing many health benefits. Legumes such as beans, lentils, and chickpeas are rich in fermentable dietary fiber, and RS can be included in this fiber group. These legumes are not considered a "typical" source of starch and have not been extensively studied as a source of RS. There are still insufficient data on modern non-thermal methods like high-pressure processing (HPP) and combining this method with refrigerated storage. The study aimed to investigate and compare the effects of HPP and HPP combined with refrigerated storage on the RS content of legumes, particularly white beans, green lentils, and chickpeas. Different pressure levels and processing times were used to evaluate changes in RS content and to assess the total fiber content and fiber fraction of the tested legumes. Our study showed that the increase in pressure and pressurization time affected changes in the RS content of the examined legumes. Furthermore, the cooling process of previously pressurized samples resulted in a significant increase in RS content. [ABSTRACT FROM AUTHOR]

Due to the requirements for quality testing and breeding Tartary buckwheat (Fagopyrum tartaricum Gaerth), it is necessary to find a method for the rapid detection of starch content in Tartary buckwheat. To obtain samples with a continuously distributed chemical value, stable Tartary buckwheat recombinant inbred lines were used. After scanning the near-infrared spectra of whole grains, we employed conventional methods to analyze the contents of Tartary buckwheat. The results showed that the contents of total starch, amylose, amylopectin, and resistant starch were 532.1–741.5 mg/g, 176.8–280.2 mg/g, 318.8–497.0 mg/g, and 45.1–105.2 mg/g, respectively. The prediction model for the different starch contents in Tartary buckwheat was established using near-infrared spectroscopy (NIRS) in combination with chemometrics. The Kennard–Stone algorithm was used to split the training set and the test set. Six different methods were used to preprocess the spectra in the wavenumber range of 4000–12,000 cm
−1 . The Competitive Adaptive Reweighted Sampling algorithm was then used to extract the characteristic spectra, and the prediction model was built using the partial least squares method. Through a comprehensive analysis of each parameter of the model, the best model for the prediction of each nutrient was determined. The correlation coefficient of calibration (Rc) and the correlation coefficient of prediction (Rp) of the best models for total starch and amylose were greater than 0.95, and the Rc and Rp of the best models for amylopectin and resistant starch were also greater than 0.93. The results showed that the NIRS-based prediction model fulfilled the requirement for the rapid determination of Tartary buckwheat starch, thus providing an effective technical approach for the rapid and non-destructive testing of starch content in the food science and agricultural industry.

Probiotics and prebiotics have gained attention for their potential health benefits. However, their efficacy hinges on probiotic survival through the harsh gastrointestinal environment. Microencapsulation techniques provide a solution, with resistant starch (RS)-based techniques showing promise in maintaining probiotic viability. Specifically, RS-encapsulated probiotics significantly improved probiotic survival in gastric acid, bile salts, and simulated intestinal conditions. This study investigated the effects of a resistant-starch-encapsulated probiotic cocktail (RS-Pro) in the context of 5-fluorouracil (5-FU) chemotherapy, which frequently induces microbiota dysbiosis and intestinal mucositis. Female BALB/c mice were divided into three groups: a 5-FU group, a 5-FU+Pro group receiving free probiotics, and a 5-FU+RS-Pro group receiving RS-encapsulated probiotics. After 28 days of treatment, analyses were conducted on fecal microbiota, intestinal histology, peripheral blood cell counts, and body and organ weights. It was revealed by 16S rRNA MiSeq sequencing that 5-FU treatment disrupted gut microbiota composition, reduced microbial diversity, and caused dysbiosis. RS-Pro treatment restored microbial diversity and increased the population of beneficial bacteria, such as Muribaculaceae, which play roles in carbohydrate and polyphenol metabolism. Furthermore, 5-FU administration induced moderate intestinal mucositis, characterized by reduced cellularity and shortened villi. However, RS-Pro treatment attenuated 5-FU-induced intestinal damage, preserving villus length. Mild leukopenia observed in the 5-FU-treated mice was partially alleviated in 5-FU+Pro and 5-FU+RS-Pro groups. These findings suggest that RS-Pro may serve as an adjunct to chemotherapy, potentially reducing adverse effects and improving therapeutic outcomes in future clinical applications.

Common bakery and many other cereal products are characterised by high glycaemic index values. Given the increasing number of people suffering from type 2 diabetes at a very young age, technological approaches to reduce the glycaemic index of cereal products are extremely important. In addition to increasing the dietary fibre content, either by using wholemeal flours or flours with added fibre from other sources, practices leading to an increase in resistant starch content are also of great interest. This review summarises the most important technological processes used to reduce the glycaemic index of bread and other bakery products. The summarization shows that the potential of various technological processes or their physical and physicochemical modifications to reduce the glycaemic index of common bakery products exists. At the same time, however, it has been shown that these processes have not been sufficiently explored, let alone applied in production practice. [ABSTRACT FROM AUTHOR]

The development of Green banana (GB) starch in prebiotic foods to address health problems such as diabetes. It is modified by phosphate cross‐linking to increase the resistant starch content, improve functional properties, and reduce digestible starch consumption. The starch is modified using a mixture of sodium trimetaphosphate (STMP) and sodium tripolyphosphate (STPP) with 6 to 12 wt%ratios in the presence of sodium sulfate. The results showed an increase in phosphorus content from 0.18% to 0.45% corresponding to the increase in sodium trimetaphosphate/sodium tripolyphosphate ratios. Resistant starch reached 60 wt% after increasing the concentration of phosphate agent above 10 wt% and rapidly digestible starch decreased significantly. Accordingly, the physicochemical properties of starch changed significantly. Phosphate cross‐linking led to disruption of the crystalline structure of starch granules and fragmentation, reducing enthalpy and increasing gelatinization temperature. The oil and water absorption and freeze‐thaw stability of treated starch increased. While water absorption and solubility index of starch decreased significantly as the result of phosphate cross‐linking. Modified starch is used for the production of rice noodles. From 10 to 30 wt% of 10P modified starch mixed, cooking fracture rate is not more than 10% and resistant starch content is over 41 wt%. [ABSTRACT FROM AUTHOR]

Resistant starch has gained substantial attention in recent years due to its potential health benefits. Among the various sources of RS, legumes have appeared as a prominent and promising contributor. Legumes like beans, lentils, and chickpeas, comprise a unique composition that promotes the resistant starch formation during cooking and processing. The review begins by presenting an overview of resistant starch and its classification based on its structure and digestibility. The mechanisms by which legume‐based resistant starch impacts human health are discussed, including its potential role in controlling postprandial glucose and insulin responses, improve satiety, boost colonic health, and influence lipid metabolism. The promising role of resistant starch from legumes in controlling chronic diseases like obesity, cardiovascular disorders, and type 2 diabetes is also explored. This review briefly covers the recent advancements in regulating the starch biosynthesis pathway through the utilization of RNA interference (RNAi) and CRISPR/Cas9 techniques. In summary, the association between resistant starch and legumes offers a compelling pathway to enhance human health and mitigate the risk of chronic diseases. Legumes as a regular part of the diet can be a viable and effective approach to augment resistant starch intake and harness its potential health‐promoting effects. [ABSTRACT FROM AUTHOR]

AMYLOSE , *CORNSTARCH , *GENETIC variation , *ANALYSIS of variance - Abstract
Amylose and resistant starch (RS) possess numerous industrial applications and health benefits. However, maize grains possess low amylose (<35%) and RS (<5%). To date, no information is available on the genetic variability of amylose and RS in subtropical maize. Here, 21 hybrids developed using half‐diallel mating design are evaluated for starch parameters at three locations. Analysis of variance (ANOVA) revealed a minor contribution for environments for amylose and RS. Amylose (22.2%–49.1%) and RS (1.02%–23.9%) showed wide variation among the hybrids. The experimental hybrids possessed significantly higher amylose (38.1%) and RS (20.9%) over the check hybrids (amylose: 29.1%, RS: 2.3%). PUSA‐AML‐H12, PUSA‐AML‐H18, and PUSA‐AML‐H16 are observed to be the most promising hybrids. Amylose and RS are positively correlated (r = 0.45), while total starch (TS) is negatively correlated with RS (r = −0.53). PMI‐AML‐147, PMI‐AML‐149, and PMI‐AML‐146 are the best general combiners for amylose and RS. Pusa‐AML‐H1, Pusa‐AML‐H12, and Pusa‐AML‐H5 emerged as the best specific combiners for amylose and RS. Both additive and nonadditive variances are important for amylose and RS. This is the first study of amylose and RS in a subtropical maize background, which could be significant in improving amylose and RS. [ABSTRACT FROM AUTHOR]

- Abstract
Chemically modified mandua starch was successfully synthesized and applied to coat mesalamine-loaded matrix tablets. The coating material was an aqueous dispersion of mandua starch modified by sodium trimetaphosphate and sodium tripolyphosphate. To investigate the colon-targeting release competence, chemically modified mandua starch film-coated mesalamine tablets were produced using the wet granulation method followed by dip coating. The effect of the coating on the colon-targeted release of the resultant delivery system was inspected in healthy human volunteers and rabbits using roentgenography. The results show that drug release was controlled when the coating level was 10% w/w. The release percentage in the upper gastric phase (pH 1.2, simulated gastric fluid) was less than 6% and reached up to 59.51% w/w after 14 h in simulated colonic fluid. In addition to in vivo roentgenographic studies in healthy rabbits, human volunteer studies proved the colon targeting efficiency of the formulation. These results clearly demonstrated that chemically modified mandua starch has high effectiveness as a novel aqueous coating material for controlled release or colon targeting. [ABSTRACT FROM AUTHOR]

RICE , *GENETIC variation , *GERMPLASM , *RED rice , *HAPLOTYPES , *AMYLOSE - Abstract
The increasing incidence of diabetes and obesity poses a major threat to global human health worldwide. Increasing the consumption of resistant starch (RS) foods could reduce the occurrence of these chronic diseases.Accurate identification and screening of germplasm resources with high RS content is the initial step in breeding efforts, and Yunnan Province is recognized as the largest center of genetic diversity in Chinese rice varieties. However, there is a lack of systematic studies of genetic variation and evolution of RS content in rice landraces within this region. Here, we selected the SSIIIa gene as the subject that affected the content of RS in rice endosperm and analyzed its natural variation in 93 rice landraces in Yunnan province. Analyses of gene sequence information demonstrated that the 93 landraces were divided into 11 haplotypes and 10 protein types. Evolutionary analysis revealed that indica and japonica rice in these landraces appeared to have experienced different evolutionary. Among these haplotypes, the H4 haplotype exhibited the highest genetic similarity to the two Oryza rufipogon of Yunnan, and the content of RS was significantly higher than other haplotypes. Furthermore, association analysis identified 9 SNPs that consistently correlated with RS content, and revealed several new mutation sites. In addition, haplotypes with high RS content generally had higher amylose content and lower gel consistency. These results provided important experimental evidence for the utilization of high RS germplasm, and also lay the groundwork for further genetic research on the process of RS formation.

Physical techniques are widely applied in the food industry due to their positive impact on food quality and the environment. Temperature differences can effectively modify starch, but the resulting changes in starch structure and quality remain unclear. In this study, the corn starch was processed with high temperature, low temperature, and temperature difference (TD), including high temperature before low temperature (H-L) and low temperature before high temperature (L-H). The results showed that high temperature induced the umbilicus to concave inward shape and sharply decreased the amylose content, while low temperature increased the surface micropores and reduced the A-chain. TD reduced the fluorescence intensity and increased the clearness of the growth ring. TD elevated the relative crystallinity (RC), short-range order, A/B
1 chains, hydrolysis parameters, and resistant starch (RS), and reduced amylose content, B2 /B3 chains, and viscosity. Moreover, the corn starches treated by H-L had lower amylose content and higher RC, 1047/1022, A-chain, and RS than those treated by L-H. Overall, high temperature degraded the amylose and low temperature destroyed the amylopectin. During the TD, H-L can accelerate the starch molecular rearrangement more than the opposite temperature treatment order. These results will help produce novel starches for better food applications.

- Abstract
Intricate ecosystem of the human gut microbiome is affected by various environmental factors, genetic makeup of the individual, and diet. Specifically, resistant starch (RS) is indigestible in the small intestine but nourishes the gut microbiota in the colon. Degradation of RS in the gut begins with primary degraders, such as Bifidobacterium adolescentis and Ruminococcus bromii. Recently, new RS degraders, such as Ruminococcoides bili, have been reported. These microorganisms play crucial roles in the transformation of RS into short-chain fatty acids (SCFAs), such as acetate, propionate, and butyrate. SCFAs are necessary to maintain optimal intestinal health, regulate inflammation, and protect against various illnesses. This review discusses the effects of RS on gut and highlights its complex interactions with gut flora, especially the Ruminococcaceae family. [ABSTRACT FROM AUTHOR]

Compared with the wheat steamed bread, this article was to explore the quality (color difference, structure, texture, sensory evaluation, etc.) and physiological activity (antioxidant properties, in vitro digestive characteristics and glucose production index) of the steamed breads with different ratios of black rice spent grains (BRSG). The results showed that BRSG had significant effects on the specific volume, color difference, structure and texture of steamed bread (P<0.05). When the BRSG addition amount was 5%, the BRSG steamed bread had better morphology and odor and taste and more popular than those of wheat steamed bread. The polyphenol content (0.066-0.088 mg/g), flavonoid content (0.266-0.379 mg/g), DPPH radical scavenging rate (25.1%-70.4%) and ABTS+ radical scavenging rate (37.4%-71.6%) of BRSG steamed bread increased significantly (P<0.05) with the increase of BRSG addition. Meanwhile, BRSG could improve the content of resistant starch in steamed bread, when the addition amount was 15%, the content of resistant starch increased by 1.49 times, which could be suitable for the preparation of resistant starch products. In addition, it could lower the glycemic index and apply to the preparation of auxiliary hypoglycemic products. [ABSTRACT FROM AUTHOR]

Food envy is a feeling of isolation experienced by diabetic and obese individuals who have dietary restrictions that prevent them from eating their preferred starchy foods. This can lead to feelings of exclusion and exacerbation in social situations. The psychological strain and emotional toll of avoiding certain foods due to medical restrictions can have negative effects on a person's health, including a higher risk of eating foods to fit in with society and worsen their medical conditions. Rice and yam are popular foods in South Eastern Nigeria, but there is limited information on cooking methods to increase the resistant starch. This lack of information can lead to frustration and feelings of deprivation, making it harder for individuals to adhere to their dietary restrictions. Limited food options may result in nutrient deficiencies, compromising their overall health and well-being. This study aimed to study the effect of different cooking methods, namely conventional and steaming methods, and different cooling methods at room temperature and in the fridge on the resistant starch contents as well as the non-resistant starch contents of rice and yam. The result showed the highest increase in resistant starch of rice (from 1.24 ± 0.42a to 7.41 ± 0.32b) and the highest decrease in the non-resistant starch (from 86.97 ± 2.58a to 36.87 ± 4.87b) when cooked by steaming method and cooled in the fridge at 4 °C for 12 hours. The cooking methods only had a significant increase in the resistant starch of yam only when cooked by conventional boiling method and cooled at room temperature (2.00 ± 0.53a to 5.28 ± 0.18b), though all the cooking methods generally had a decrease in the non-resistant starch contents of yam except the conventional boiling method when cooled at room temperature (84.53 ± 2.60a to 82.55 ± 5.12a).

Abstract Resistant starch from plantain (Macho Musa paradisiaca L.) and banana (Roatan Musa sapientum L.) varieties was chemically modified by crosslinking using epichlorohydrin (EPI). These modified starches were subjected to in vitro digestibility studies using the Englyst method to determine the content of rapidly digestible starch (RDS), slowly digestible starch (SDS) and resistant starch (RS). The thermal stability of these crosslinked starches was evaluated by gelatinization and retrogradation analyses, and their enthalpies were determined using differential scanning calorimetry (DSC). Additionally, their functional properties were evaluated. Chemical modification with EPI significantly increased the RS content in both starch varieties compared to that in native starch. The enthalpy and gelatinization temperature decreased in the EPI-modified starches of both varieties, indicating lower thermal stability during the gelatinization process compared to that of native starch. In general, both varieties of crosslinked plantain starch had lower viscosity (0.43 Pa*s) than did native starch (0.58 Pa*s). The results indicates that this starch crosslinked with EPI constitutes an alternative for use in food for people with health problems such as high cholesterol levels or postprandial insulin concentrations.

Abstract The ever‐increasing ranges of starch applications have been restricted by some of its inherent adverse characteristics like retrogradability, gel opacity, low resistibility to variations of pH, and elevated shear/temperatures. Starch modification through various physical, chemical, and enzymatic methods has been proposed as the most mature platform to tackle such drawbacks. Along with their outstanding potential in enhancing the starch's technofunctional characteristics, physicochemical modifications could remarkably customize starch nutritional/digestibility attributes. For instance, physical modifications could remarkably change starch digestibility by manipulating the granular architecture while chemical approaches change it by altering the chemical structure of starch molecules, making them unrecognizable to digestive enzymes. Such alterations could even be more challenging upon applying a combination of starch modifications. The changes in starch digestibility through its modification via single, double, and multiple modifications have been overviewed in this review.

Variations of processing rice into cooked rice had long been developed. One of the rice products that had been widely circulated in the community was savory rice. Savory rice with an instantization processed was more practical in serving. This research aimed to determine the physical, chemical, functional, and sensory characteristics of instant savory rice compared to instant white rice. The stages of processing instant savory rice included washing, soaking, cooking, freezing, and drying. The freezing process was carried out at -20 °C for 24 h. The drying process for instant savory rice used a fluidized bed dryer for 3 h. Instant white rice was used as a control. The porosity level of instant savory rice was lower than instant white rice as indicated by the yield (95.77%), bulk density (0.57 g/mL), rehydration time (14.34 min), rehydration ratio (2.86), expansion volume ratio (2.26), and water absorption capacity (69.50%). Instant savory rice contained moisture content (8.48%), ash content (3.93%), fat content (5.56%), protein content (7.54%), and starch digestibility (54.84%) which was higher than instant white rice. Instant savory rice had carbohydrate content (82.97%), amylose content (32.39%), amylopectin content (46.59%), starch content (79.98%), and resistant starch content (1.90%) lower than instant white rice. In terms of sensory test results revealed that instant savory rice after rehydration was preferred by consumers compared to instant white rice regarding color, aroma, taste, texture, and overall with a score of 5.39-5.84.

Abstract This review covers the significance of green banana resistant starch (RS), a substantial polysaccharide. The food industry has taken an interest in green banana flour due to its 30% availability of resistant starch and its approximately 70% starch content on a dry basis, making its use suitable for food formulations where starch serves as the base. A variety of processing techniques, such as heat‐moisture, autoclaving, microwaving, high hydrostatic pressure, extrusion, ultrasound, acid hydrolysis, and enzymatic debranching treatments, have made significant advancements in the preparation of resistant starch. These advancements aim to change the structure, techno‐functionality, and subsequently the physiological functions of the resistant starch. Green bananas make up the highest RS as compared to other foods and cereals. Many food processing industries and cuisines now have a positive awareness due to the functional characteristics of green bananas, such as their pasting, thermal, gelatinization, foaming, and textural characteristics. It is also found useful for controlling the rates of cancer, obesity, and diabetic disorders. Moreover, the use of GBRS as prebiotics and probiotics might be significantly proved good for gut health. This study aimed at the awareness of the composition, extraction and application of the green banana resistant starch in the future food products.

Abstract The aim of this study is to increase the functionality of rice starch by modifying matcha tea extract and to determine the effect on some physicochemical properties and starch digestibility. According to the data analyzed, treatment with matcha extract was effective in increasing the nutritional value of native rice starch. At the highest level of extract addition, total phenolic and flavonoid content reached 129.54 mg/100 g and 40.16 mg/100 g, respectively, as no phenolic or flavonoid content was detected in control. In addition, the highest DPPH and FRAP values were determined to be 296.62 μmol TE/100 g and 814.89 mg/100 g, respectively, at the highest extract addition level. Treatment with matcha extract significantly reduced the eGI of native rice starch from to 94.61 to 64.63, while resistant starch was increased from 0.90 to 33.43%. According to the physiochemical analysis, there was a positive correlation between the extract ratio and the water‐holding capacity of rice starch due to the high hydrophilic capacity of the phenolic compounds. In addition, the solubility and swelling power of starch were increased by treatment with matcha extract, but high temperatures had a negative effect on these physicochemical properties.

Abstract The immediate and well‐documented benefits of carbohydrate restriction include improved glycemic control in individuals with diabetes mellitus. Starch, a significant source of carbohydrates, is categorized as rapidly digestible, slowly digestible, or resistant starch (RS). RS, which is a non‐viscous fermentable fiber, has shown promise in animal studies for antidiabetic effects by improving glucose metabolism. Although the exact mechanism by which RS affects glucose metabolism remains unclear, it is expected to positively impact glucose tolerance and insulin sensitivity. The fermentation of RS by colonic microbiota in the large bowel produces short‐chain fatty acids, which exert multiple metabolic effects on glucose regulation and homeostasis. Moreover, RS may influence glucose metabolism via bile acid modulation, independent of its fermentation. Diets rich in RS could aid in blood glucose homeostasis. However, it is uncertain whether they can alter the metabolic pathology associated with glucose regulation. In essence, RS has the potential to lower postprandial glucose levels similarly to a low‐glycemic index diet. Yet, its efficacy as a medical nutrition therapy for type 2 diabetes needs further investigation. To confirm the role of RS in glycemic control and to possibly recommend it as an additional dietary approach for people with type 2 diabetes mellitus, a well‐designed, large‐scale intervention is required.

Starch is a natural plant raw material applicable in many areas of industry. In practice, it is most often used in a modified form, i.e., after various treatments aimed at modifying its properties. Modifications of native starch enable producing resistant starch, which, as a prebiotic with confirmed health-promoting properties, has been increasingly used as a food additive. The present study aimed to determine the effect of roasting retrograded starch with the addition of anhydrous glucose at different temperatures (110, 130 or 150 °C) and different times (5 or 24 h) on the modified starch's properties. The results of high-performance size-exclusion chromatography coupled with refractive index detector (HPSEC/RI) analysis and the changes observed in the solubility of starch roasted with glucose in DMSO, as well as in its other properties, confirm the changes in its molecular structure, including thermolytic degradation and the ongoing polymerization of starch with added glucose.

Summary: Resistant starch (RS) has been shown to manipulate food digestion and nutrient metabolism as well as being important in promoting gut health. However, the presence of RS varies across diverse food systems depending upon process conditions. To investigate this, chickpeas, potatoes, arrowroots, unripe bananas and oats were subjected to boiling and pressure cooking at various cooking durations and the RS% was determined. After 45 min of boiling and 15 min of pressure cooking, RS% of chickpeas increased by ~29% and ~41%, respectively. Increasing the cooking time, together with boiling and pressure cooking, led to higher RS% in chickpeas, mainly due to the retrogradation of starch after gelatinisation. In contrast, boiling and pressure cooking led to a reduction in RS% for potatoes, arrowroots, unripe bananas and oats, while a further decrease was encountered with the increase in processing time. After 45 min of boiling, RS% of potatoes, arrowroots, unripe bananas, and oats were reduced by 58%, 22%, 80% and 70%, respectively. After 15 min of pressure cooking, RS% of potatoes, arrowroots and unripe bananas were reduced by 41%, 22% and 83%, respectively. This was mainly due to the disruption of the ordered structure of starch molecules during thermal processing in the presence of water. This study clearly elucidates the impact of boiling and pressure cooking on RS% as a function of processing time and type of RS source. [ABSTRACT FROM AUTHOR]

LEMON juice , *STARCH , *CITRIC acid , *SUSTAINABLE chemistry , *ESTERIFICATION , *SOCIAL acceptance , *FOOD industry - Abstract
The application of chemical operations in food processing, in which pure chemical compounds are used to modify food ingredients, often raises social concerns. One of the most frequently modified dietary substances is starch, e.g., E1401–E1404, E1412–E1414, E1420, E1422, E1440, E1442, and E1450–E1452. An alternative solution to chemical treatments seems to be the use of raw materials naturally containing substrates applied for starch modification. Heating starch with a lemon juice concentrate can be considered a novel and effective method for producing starch citrate, which is part of the so-called "green chemistry". The modified preparations obtained as a result of potato starch esterification with natural lemon juice had a comparable degree of esterification to that of the esters produced with pure citric acid. In addition, the use of the juice doubled their resistance to amylolytic enzymes compared to the preparations made with pure acid. Replacing citric acid with lemon juice can facilitate the esterification process, and the analyzed properties of both types of modified preparations indicate that starch esters produced with pure citric acid can be successfully replaced by those produced using natural lemon juice, which may increase the social acceptance of these modified preparations.

Tubers are domestic commodities that contain carbohydrates. This commodity can be used as a functional food ingredient which was previously only used as an energy source. This occurs due to a need for more information regarding the functional properties that can be utilized from these tubers. Therefore, this article was created to provide information that apart from being a source of energy, this tuber can also offer health benefits. This research method is based on literature studies from journals and other scientific literature. From searching the literature, it turns out that functional properties come from tubers, and processing can maintain and even increase this functional value. The functional compounds contained in tubers are bioactive compounds. Some of the bioactive compounds found in tubers include saponins, bioactive proteins, phenolic compounds, glycoalkaloids, phytic acid, carotenoids, and ascorbic acid. These compounds are generally found in tubers that have not been specially cultivated by the community, including dyscorea, colocasia, or maranta. One of the processing methods that can be carried out to improve the functional properties of tubers, especially starch, resistant starch is the use of modification and Microwave Assisted Extract (MAE).

This review covers the significance of green banana resistant starch (RS), a substantial polysaccharide. The food industry has taken an interest in green banana flour due to its 30% availability of resistant starch and its approximately 70% starch content on a dry basis, making its use suitable for food formulations where starch serves as the base. A variety of processing techniques, such as heat‐moisture, autoclaving, microwaving, high hydrostatic pressure, extrusion, ultrasound, acid hydrolysis, and enzymatic debranching treatments, have made significant advancements in the preparation of resistant starch. These advancements aim to change the structure, techno‐functionality, and subsequently the physiological functions of the resistant starch. Green bananas make up the highest RS as compared to other foods and cereals. Many food processing industries and cuisines now have a positive awareness due to the functional characteristics of green bananas, such as their pasting, thermal, gelatinization, foaming, and textural characteristics. It is also found useful for controlling the rates of cancer, obesity, and diabetic disorders. Moreover, the use of GBRS as prebiotics and probiotics might be significantly proved good for gut health. This study aimed at the awareness of the composition, extraction and application of the green banana resistant starch in the future food products. [ABSTRACT FROM AUTHOR]

Common cooking methods were used to prepare basmati rice products, including boiling 1 (boiling by absorption), boiling 2 (boiling in extra amount of water), frying, and pressure cooking. The cooked rice was held at various temperatures and times as follows: it was made fresh (T1), kept at room temperature (20–22 °C) for 24 h (T2), kept at 4 °C for 24 h (T3), and then reheated after being kept at 4 °C for 24 h (T4). The proximate composition, total dietary fibre, resistant starch (RS), and in vitro starch digestion rate of products were examined. The effect of RS on blood glucose and lipid profiles was measured in humans and rats, including a histopathological study of the liver and pancreas in rats. The basmati rice that was prepared via boiling 1 and stored with T3 was found to be low in glycaemic index and glycaemic load, and to be high in resistant starch. Similarly, in rats, the blood glucose level, cholesterol, triglycerides, and LDL were reduced by about 29.7%, 37.9%, 31.3%, and 30.5%, respectively, after the consumption of basmati rice that was prepared via boiling 1 and stored with T3. Awareness should be raised among people about the health benefits of resistant starch consumption and the right way of cooking. [ABSTRACT FROM AUTHOR]

There is a growing demand from consumers on functional food and beverages. Potential probiotics such as L. lactis could be incorporated into food and beverages as a value-added ingredient. However, sufficient viable cell counts are required to be present in the food or beverages products to confer health benefits to hosts. Therefore, this study aimed to encapsulate food-grade recombinant L. lactis NZ3900 in 1:1, 2:1, and 3:1 ratio of sodium alginate-resistant starch matrix using co-extrusion technique and evaluate its storage stability in coconut water. All the microbeads were spherical with size ranged from 528.33 to 560.67 μm. The microbeads with 2:1 ratio sodium alginate-resistant starch had the highest microencapsulation efficiency (91.1%) and highest survivability (78.4%) after 6 h of simulated sequential digestion. After 4 weeks of storage, L. lactis microbeads had higher survivability in coconut water with 11.4 log
10 CFU/g and lesser reduction in total soluble solids than free cells. There was no significant difference (p > 0.05) between the coconut water with free cells and microbeads in terms of pH, titratable acidity, and viscosity after 4 weeks of storage. At the end of the storage, the coconut water with microbeads had pH 3.9, 0.32% malic acid, 5.4 °Brix, 1.4 cP of viscosity, and total colour changes of < 1.26. This study shows that co-extrusion technique with sodium alginate-resistant starch matrix are suitable for the formation of L. lactis microbeads. Moreover, the stability of the L. lactis microbeads in coconut water showed its potential to be marketed as a functional isotonic beverage. [ABSTRACT FROM AUTHOR]- Published

In vitro gut models allow for the study of the impact of molecules on human gut microbiota composition and function without the implication of the host. However, current models, such as the Simulator of Human Intestinal Microbial Ecosystem (SHIME®), are expensive, time-consuming, and require specialized personnel. Homemade in vitro models that lessen these issues have limited evidence of their humanlike functionality. In this study, we present the development of a low-cost and easy-to-use bioreactor with the proven functionality of human microbiota. In our model, we evaluated the capability of replicating human gut microbiota growth and the response of the human bacterial community to a prebiotic, resistant starch, particularly resistant starch type 2 (RS2). Our bioreactor produced an environment that was stable for pH, temperature, and anaerobic conditions. The bioreactor consistently cultivated bacterial communities over a 48 h time period, replicating the composition of the gut microbiota and the associated metabolite production response to RS2, in line with prior human studies. In response to the RS2 prebiotic, we observed an increase in Bifidobacterium adolescentis and Bifidobacterium faecale and an increase in the production of the short-chain fatty acids such as acetate, propionate, and isobutyrate. Taken together, these data demonstrate that our low-cost and user-friendly prototype bioreactor model provides a favorable environment for the growth of human gut microbiota and can mimic its response to a prebiotic.

In this study, chestnuts were processed into flour, and the obtained chestnut flour (CF) was passed through a sieve with an aperture size of 212 µm. Then the physicochemical properties, digestible and resistant starch contents of CF1 (<212 µm), CF2 (≥212 µm), and commercial chestnut flour (CCF) were determined. It was found that CCF had the highest values in terms of proximate composition, total soluble polyphenol content (891.25 mg GAE/100 g), and antioxidant activity (ABTS: 1552.11 mg TE/100 g, DPPH: 2003.01 mg TE/100 g). On the other hand, CF1 was superior in terms of resistant starch content (39.31 g/100 g, dw) (p < 0.05). The resistant starch content of CF1 was approximately 1.5-fold and 3-fold higher than CCF and CF2, respectively. Furthermore, the rapidly digestible starch content of CF1 (2.1 g/100 g, dw) and CF2 (0.93 g/100 g, dw) was quite lower than CCF (12.64 g/100 g, dw) (p < 0.05). Moreover, CF1 exhibited lower (p < 0.05) water, alkaline water, and sodium carbonate retention capacities, which make it a potential good flour for cookie and cracker production. In contrast, CF2 could be evaluated as a good ingredient for noodle-type foods due to its lower water solubility index. Considering the least gelation concentrations of samples, it was seen that CF1 (% 10) could also be valorized as a thickening or gelation agent in the food industry, as well as CCF (% 6).

In this study, we investigated the structural properties and digestibility of wheat starch treated with octenyl succinic anhydride (OSA). For the experiment, the samples were reacted with 2, 4, 6, 8, and 10% OSA (pH 8.5–9.0) for 2 h. A light micrograph showed that there was no difference in the morphology and Maltese cross between native and OSA-treated starch. The X-ray diffraction (XRD) patterns of the native and OSA-treated starches showed typical A-type diffraction. In addition, the Fourier transform infrared (FT-IR) spectrum showed a distinct carbonyl peak at approximately 1730 cm
−1 , indicating the stretching vibration of the C=O bond of the ester group. The degree of substitution (DS) and content of resistant starch (RS) increased with increasing concentrations of treated OSA because of the increase in ester bonds. In particular, RS was thermostable compared to the RS content in uncooked and cooked starch. Blood glucose levels and response in vivo decreased as the OSA concentration increased. Treatment of wheat starch with 8% OSA concentration produced 35.6% heat-stable resistant starch. These results suggest that starch modified with OSA can be used to produce functional foods for diabetes. [ABSTRACT FROM AUTHOR]- Published

To enhance the resistant starch (RS) content of corn starch, in this work, carboxymethyl chitosan/corn starch/sodium alginate microcapsules (CMCS/CS/SA) with varying concentrations of SA in a citric acid (CA) solution were designed. As the SA concentration increased from 0.5% to 2%, the swelling of the CMCS/CS/SA microcapsule decreased from 15.28 ± 0.21 g/g to 3.76 ± 0.66 g/g at 95 °C. Comparatively, the onset, peak, and conclusion temperatures (T
o , Tp , and Tc ) of CMCS/CS/SA microcapsules were higher than those of unencapsulated CS, indicating that the dense network structure of microcapsules reduced the contact area between starch granules and water, thereby improving thermal stability. With increasing SA concentration, the intact and dense network of CMCS/CS/SA microcapsules remained less damaged after 120 min of digestion, suggesting that the microcapsules with a high SA concentration provided better protection to starch, thereby reducing amylase digestibility. Moreover, as the SA concentration increased from 0.5% to 2%, the RS content of the microcapsules during in vitro digestion rose from 42.37 ± 0.07% to 57.65 ± 0.45%, attributed to the blocking effect of the microcapsule shell on amylase activity. This study offers innovative insights and strategies to develop functional starch with glycemic control properties, holding significant scientific and practical value in preventing diseases associated with abnormal glucose metabolism.

Emulsified meat products contain high animal fat content, and excessive intake of animal fat is not good for health, so people are paying more and more attention to reduced-fat meat products. This study investigated the impact of varying proportions of pork back-fat and/or resistant starch on the proximate composition, water and fat retention, texture properties, color, and rheology characteristic of pork batter. The results found that replacing pork back-fat with resistant starch and ice water significantly decreased the total lipid and energy contents of cooked pork batter (p < 0.05) while improving emulsion stability, cooking yield, texture, and rheology properties. Additionally, when the pork back-fat replacement ratio was no more than 50%, there was a significant increase in emulsion stability, cooking yield, hardiness, springiness, cohesiveness, chewiness, and L* and G' values (p < 0.05). Furthermore, resistant starch and ice water enhanced myosin head and tail thermal stability and increased G' value at 80 °C. However, the initial relaxation times significantly decreased (p < 0.05) and the peak ratio of P
21 significantly increased from 84.62% to 94.03%, suggesting reduced fluidity of water. In conclusion, it is feasible to use resistant starch and ice water as a substitute for pork back-fat in order to produce reduced-fat pork batter with favorable gel and rheology properties.
