Summary: Starch is an ideal wall material for controlled release in oral delivery systems, but its poor mechanical behavior and high water permeability can be improved by modifying its amphiphilic nature through the use of surfactants. This study found that non-ionic surfactants (such as Tween) generally reduced the viscosity of starch, while saturated medium-chain ionic surfactants (such as NaFA) greatly increased the viscosity and rheological modulus of starch, and both surfactants inhibited starch digestion.

Summary: This study investigated the contribution of molecular structure to the digestibility of jackfruit seed starches (JSS) using chemical surface gelatinization. The starches were subjected to varying degrees of gelatinization, and their structure features and in vitro digestion were studied. The remaining JSS granules exhibited a rough surface with a lamella structure, and the distribution of amylose content was slightly higher in the middle layer. The resistant starch content of JSS granules showed a decrease from the periphery to the core, consistent with the distribution of relative crystallinity. JSS granules with higher degrees of gelatinization exhibited lower gelatinization temperature and enthalpy.

Summary: The effect of chlorogenic acid (CA) on the dielectric response of lotus seed starch (LS) after microwave treatment was examined. The LS-CA complex showed more efficient microwave-energy-to-thermal-energy conversion efficiency than LS. LS-CA had better gelatinization and starch crystalline structure degradation compared to LS, leading to increased thermal stability. The presence of LS-CA complex improved the slow-digestion property of lotus seed starch by increasing resistant and slowly digested starch, and chlorogenic acid inhibited α-amylase activity to slow starch digestion.

Summary: The study investigated the effects of adding jicama non-starch polysaccharides (PEP-3P & PEP-6P) with different molecular structures on the structure, gelatinization properties, and in vitro digestibility of gelatinized oat starch (OS). The results showed that the addition of PEPs did not significantly affect the swelling power, solubility, crystalline shape, and apparent viscosities of the starch. However, it increased thermal resistance, gel strength, and the proportion of amorphous area, while decreasing the content of rapidly digestible starch (RDS).

Summary: The study found that longan seed polyphenols (LSPs) significantly suppressed blood glucose response in mice in a dose-dependent manner. By inhibiting the activity of alpha-amylase through hydrogen bonding and van der Waals forces, LSPs changed the secondary structure of the enzyme, leading to reduced enzyme activity. This suggests the potential application of LSPs as a hypoglycemic agent in functional foods.

Summary: In this study, complex gels of fermented indica rice starch (FIRS) and soybean protein isolate (SPI) were prepared to investigate the relationship between gel characteristics and digestive properties. The results showed that adding 9% SPI increased the resistant starch content and decreased the glycemic index of the system. Gel characteristics analysis revealed that adding SPI enhanced the gel strength of FIRS and improved its gelatinization stability. Rheological properties analysis indicated that hydrophobic, hydrogen bonding, and electrostatic interactions were at play between FIRS and SPI, with hydrophobic interaction being the most prominent. Furthermore, fractionation of SPI into its 11S and 7S globulin components demonstrated their different contributions to viscoelasticity and starch order.

Summary: The objective of this study was to compare the structural, thermal, rheological and digestive properties of highland barley starch (HBS) extracted by different methods. Ultrasound extraction led to lower molecular weight and higher content of damaged starch, while double enzyme extraction (DE) resulted in higher molecular weight and higher content of short amylopectin. DE extraction also showed the highest relative crystallinity and good short-range structure, leading to better thermal stability and higher values of G' and G''.

Summary: This study focuses on the low starch digestive properties of highland barley by examining its composition, starch structural orders, and kernel structure. Results show that blue varieties have poor chemical composition, lower starch crystallinity, and higher short-range structural order degree, but only slightly higher starch digestibility as flour. The starch digestibility of all varieties in chyme form is lower compared to flour, with blue highland barley chyme showing the lowest starch digestibility. Kernel structural analysis reveals that the blue highland barley kernel structure effectively inhibits digestion.

Summary: This study investigated the multilevel structures, thermal and digestion properties of litchi seed starches from six varieties, providing insights into their distinct characteristics and potential applications in various industries. The results showed that different varieties of litchi seed starch had similar appearances and crystalline structures, but varied in size distributions and gelatinization properties. However, variety did not play a major role in regulating the digestibility of cooked litchi seed starch.

The modified LSCNF exhibited higher viscosity and improved interfacial properties. The emulsions stabilized by LSCNF showed gel behavior and good recovery properties, making it a suitable fat replacement in biscuits to enhance the dough texture and inhibit FFA release during digestion.

Summary: Pomace, a by-product, can be improved by high pressure homogenisation (HPH), enzymatic hydrolysis (EH), and high hydrostatic pressure (HHP) modifications to enhance its functional properties as litchi pomace insoluble dietary fibre (LPDF). The modifications changed the microstructure of LPDF, resulting in more porous structures. HPH modification exhibited significant effects on water holding, water swelling, and oil retention capabilities of LPDF, as well as increased total phenol content and antioxidant activity. The modified LPDFs' diverse structural features and strong affinity contribute to its functional properties, such as starch digestion inhibition.

Summary: This study investigated the effect of insoluble dietary fiber (IDF) from wheat bran on starch digestion in vitro and explored the underlying mechanisms of IDF's inhibition towards a-amylase. The results showed that IDF significantly slowed down starch digestion and reduced digestible starch content. The enzyme inhibition kinetics revealed that IDF acted as a mixed-type inhibitor to a-amylase, binding to the enzyme and causing alterations in its secondary structure. This interaction hindered the enzyme's activity and prevented it from capturing substrates. These findings have implications for the use of IDF in functional foods for managing postprandial blood glucose.

Summary: This study aimed to explore the potential of GABA and fermented litchi juice enriched with GABA (FLJ) in protecting against obesity in a high-fat diet mouse model. Supplementation of GABA and FLJ showed an anti-obesogenic effect by reducing body weight gain, fat accumulation, and oxidative damage, and improving serum lipid profile and hepatic function. Sequencing of fecal samples indicated that GABA and FLJ intervention had different regulatory effects on gut microbiota dysbiosis induced by the high-fat diet.
