Article Abstract
This study prepared complexes using corn starch and white kidney bean protein (KBP) and its hydrolysates (KBPH60 and KBPH180, hydrolysates derived via enzymatic hydrolysis for 60 and 180 min, respectively) through heat-moisture treatment (HMT). The impact of HMT on the structure, physicochemical properties, and in vitro starch digestibility of these KBP/KBPH-starch complexes was systematically analyzed. Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) results showed that KBP and its hydrolysates stabilized the starch structure weakened by HMT through hydrogen bonding, promoting a more ordered crystalline arrangement and decreasing starch digestibility. Scanning electron microscopy (SEM) confirmed that HMT promoted the encapsulation of starch granules by KBP/KBPH, acting as a barrier to amylase. Both HMT and KBP/KBPH inhibited starch gelatinization, reducing paste viscosity and disrupting the starch gel network. This increased free water content and softened gel texture. HMT intensified these effects, increasing resistant starch (RS) content. KBPH, particularly HMT-KBPH180-S (heat-moisture treated complex of KBPH180 and corn starch), exhibited a pronounced inhibitory effect on starch digestibility, yielding the highest RS content. These results provide new insights into regulating starch digestibility and stability through protein hydrolysates and HMT, laying a theoretical foundation for the developing functional foods with low digestibility.

The anti-digestive properties of cross-linked starches are essential for the development of low glycemic foods. Dynamic digestion modeling simulates the human digestive process more accurately and is an effective tool to study its anti-enzymatic mechanism. The structural evolution characteristics and the generation rules of sugar derivatives of lotus seed cross-linked starch with low, medium, high cross-linking degree (LS-2CS, LS-6CS, LS-12CS, respectively) were studied and compared during in vitro dynamic simulation digestive system.

Chestnut (Castanea mollissima Blume) is a nutritionally dense food, notably rich in starch, making it an important natural source of carbohydrates and energy for human diets. However, its high content of rapidly digestible starch (RDS) limits its use in low-glycemic-index (GI) food products. This study developed a synergistic bioprocess combining Lactobacillus plantarum fermentation and pullulanase-catalyzed debranching to enhance the nutritional and structural characteristics of chestnut powder.

Islet transplantation offers a promising therapeutic strategy for type 1 diabetes patients with inadequate glycemic control or severe complications. Islet encapsulation using biocompatible materials presents a potential solution to reduce immune rejection. This study fabricated and characterized Schiff base hydrogels (CMOCs) composed of varying ratios of carboxymethyl chitosan (CMCS) and oxidized carboxymethyl starch (OCMS).

The objective of this study was to evaluate the effects of forage fiber and starch sources replacement with delactosed whey permeate (DLP) on lactation performance and total-tract nutrient digestibility of high-producing dairy cows. Ninety-six multiparous Holstein cows (88 ± 36 DIM) and dietary treatments were randomly assigned to 12 pens of 8 cows for an 8-wk treatment period, after a 2-wk covariate period. Treatments were diets fed without DLP (CON), 5% replacement of corn silage with DLP (LCS), and 5% replacement of high-moisture corn with DLP (LHMC).
