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.","PeriodicalId":501569,"journal":{"name":"Starch","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140046350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fourier transform infrared spectroscopy (FTIR) shows that the esterification reactions between OSA and the two starches are successful, and the substitution effect of OSA‐modified <jats:italic>A. squarrosum</jats:italic> starch (OSA‐AS) is better than that of OSA‐modified quinoa starch (OSA‐QS). X‐ray diffraction (XRD) analysis shows that OSA modification does not alter the crystal type of the starch particles. OSA modification increases the particle size and hydrophobicity of both starches, and the particles of OSA‐AS are smaller than that of OSA‐QS, which corresponded to the fact that N‐AS possesses a smaller particle size compared to native N‐QS. OSA‐modified starches are arranged at the interface of oil–water to stabilize the emulsion. The OSA‐AS displays better performance of stabilizing emulsion than OSA‐QS. The Pickering emulsions formed by all OSA‐modified starch samples are mainly elastic gel‐like emulsions.

The substitution of wheat flour by type I and type II complexes increases and decreases the lightness of wheat noodles, respectively. The cooking loss of noodles increases with increasing addition of complexes, which is due to the destruction of gluten networks. Textural analysis shows that type I complexes, and to a lesser extent type II complexes, reduced the hardness and increased the elasticity of cooked noodles. Noodles made with type II complex are more resistant to amylolysis than those made with type I complexes, probably due to the less susceptibility of more crystalline type II complexes to amylolysis. From this study, it is concluded that starch‐lipid complex, as a new kind of clean‐label starch with promising functionality, can be used to improve the quality and nutrition of starchy foods.","PeriodicalId":501569,"journal":{"name":"Starch","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140018253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Below the gelatinization temperature, the apparent activation energy and the frequency factor decrease with increasing rice‐particle diameter. The water sorption mechanisms of both types of rice appear to be the same in terms of the enthalpy–entropy compensation effect.

Corn starch is oxidized by hydrogen peroxide (with Cu(II) or Fe(II) ions as catalysts) in the ultrasound field. Changes in starch structure are identified based on determinations of the carboxyl, carbonyl groups, copper, iron content, molecular characterization by GPC, crystallinity, gelatinization characteristics, and surface area. Functional properties are determined based on analysis of color parameters, water binding capacity, solubility in water, and pasting characteristics. It is found that the effectiveness of the starch oxidation under ultrasound is affected by the presence and type of catalysts. The content of metal incorporated into starch during oxidation is approximately 15% lower when an ultrasound treatment is applied. When starch oxidation is assisted with ultrasound, the metal incorporation preferentially occurs in the pores and holes of the grain. Starches oxidized in the presence of Fe(II) and Cu(II) catalysts can be successfully used not only as thickeners in food industry but also as metal carriers in many industries.","PeriodicalId":501569,"journal":{"name":"Starch","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140006420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results reveal that the addition of DOPs can significantly enhance the thickness, swelling ratio, tensile strength, elongation at break, and thermal stability of the films (<i>p</i> < 0.05) whereas the water solubility and water vapor permeability are decreased. Fourier transform-infrared (FT-IR) spectroscopy results reflect interaction of chemical groups and bonds between SA and DOPs. The result of scanning of electron microscopy (SEM) indicates smooth for SA-DOPs films while control film exhibits rough. The SA-DOPs films exhibit potential antioxidant effects on 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radicals. Furthermore, the composite films exhibit remarkable inhibition of the growth of <i>Escherichia coli</i> and <i>Staphylococcus aureus</i> (<i>p</i> < 0.05). In addition, the SA-DOPs coatings can effectively reduce weight loss, inhibit polyphenol oxidase activity, extend the shelf life of the grapes at room temperature (25 ± 1 °C) for 14 days.
