However, maximum restriction in swelling power (2.54 %), solubility (2.47 %), moisture content (1.96 %), water absorption capacity (1.41 g/mL) is observed in heat moisture treated (HMT) starch. These HMT modified starches can be used in the manufacturing of baked and dairy products having reduced glycemic index, can be used as a packaging material for coating of fruits and vegetables.

MicroDSC results show that compared with D‐glucose (Glc), D‐fructose (Fru), and Suc, Alu does not significantly increase the gelatinization temperatures of the starch suspensions. Alu decreases water activity in the same degree as Fru in wheat, tapioca, corn, normal rice, and glutinous rice starch gels but not potato starch gels. Alu has a stronger suppression effect on recrystallization of normal and glutinous rice compared to potato, wheat, and tapioca after 14‐day storage of 2% starch pastes at 4 °C.

The extrusion conditions completely destructure both the HAC and waxy starch granules and the resulting materials are evaluated using SEM, XRD, FT‐IR, FTIR‐m, and TGA. The HAC‐CFA materials are shown to contain AIC having 61 V type helical structure between amylose and the CFA that are confirmed by XRD and IR spectral analysis. By TGA, extruded HAC materials containing 15% CFA are shown to have excess CFA present in addition to formed AIC. In contrast, the WC is shown not to form AIC with the CFA and only trap the CFA within the starch matrix.

This study examines two milling methods for RS3: shear milling (SM) and vibration milling (VM). Manual milling (MM) is used as a control. The particle size, morphology, crystallinity, gelatinization characteristics, and in vitro digestibility of milled RS3 are analyzed. The particle size of the VM-samples ranged from 71.92 to 107.69 µm, which is lower than SM-samples. Scanning electron microscopy shows that SM-RS3 appears as pellets, while VM-RS3 is mostly coarse flakes. From the results of RVA and DSC, VM destroys more starch than SM. The crystallization peak of VM-samples disappears, and the retention of SM-samples is well. The values of R 1047/1022 and R 995/1022 cm<sup>−1</sup> indicate that the crystal order and double helix structure of RS3 are destroyed after multiple VM shocked compared with SM. In vitro digestion experiment, resistant starch content of SM-samples is about 30%, while VM-samples are much less than SM. These findings suggest that the choice of milling methods has a significant impact on the structure and physicochemical characteristics of RS3, and it is an important step in preparing RS3.","PeriodicalId":501569,"journal":{"name":"Starch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140322335","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}

Two stages of experiment are as follows: 1) verifying the results of the meta-analysis of corn starch and flour modification by annealing method and 2) analyzing their physicochemical properties. As a result, annealing significantly improves RS content in both groups, reaching 14.18% in annealed corn flour (AF) (compared to 3.27% in native corn flour (NF)) and 21.87% in annealed corn starch (AS) (compared to 3.82% in native corn starch (NS)). The present work also confirms that the treatment unaltered birefringence properties of all samples. Moreover, pasting properties of corn starch and flour demonstrate remarkable changes. The peak viscosity of AS and NS is higher than AF and NF. In addition, gelatinization seems to occur at similar temperature, but needs extra time for starting gelatinization.

Based on the single factor tests and response surface analysis, the optimum conditions for the treatment of MF are determined as follows: pullulanase 62.6 U g−1, autoclaving 21.3 min, HMT at 100 °C, and 30.4% water content for 6.0 h. Under these conditions, the yield of RS in the flour reaches 77.42%. P‐HMT causes protein denaturation, starch gelatinization, and flour clumps in MF, facilitating starch recrystallization and interactions among short‐chain starch, monomeric proteins, and lipids. All these findings are further confirmed by the conversion of starch crystal from A‐type to B+V‐type, the improvement of starch short‐range molecular order, and the presence of more binary/ternary complexes in treated flour. In brief, the starch digestion resistance improvement in the treated flour is attributed to the recrystallization of short‐chain starch and interactions between starch and protein/lipid.","PeriodicalId":501569,"journal":{"name":"Starch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140322367","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}
