Summary: This study investigated the interaction between soybean protein isolate (SPI) and acrylamide (AA) and examined the effects of SPI on the release of AA during in vitro digestion. The results showed that AA could bind with SPI, altering the structure of SPI. The fluorescence of SPI was quenched by AA through static quenching. The main interaction forces between SPI and AA were non-covalent (van der Waals forces and hydrogen bonding) and covalent bonds. Additionally, the release of AA was significantly decreased due to its interaction with SPI under simulated gastrointestinal conditions. Different treatments of SPI, such as thermal and ultrasound treatments, were effective in reducing the release of AA, while high pressure homogenization treatments were unfavorable.

Summary: The effects of oxidized SPI emulsions on in vitro gastric stability and pepsin diffusion were investigated. The results showed that protein oxidation increased droplet size and decreased interfacial viscoelasticity. Pepsin diffusivity decreased due to the hindrance of oil droplets. After gastric digestion, protein hydrolysates formed a thick layer on the oil-water interface, reducing droplet size and free amino acid content. Protein oxidation affects interfacial protein adsorption and droplet distribution, impairing emulsion gastric digestion, which should be considered in the design of controllable delivery systems.

Summary: The study found that phosphorylation of SPI increased its apparent molecular weight and thiol content, but negatively affected gastrointestinal digestibility, especially gastric digestibility. On the other hand, glycosylation of SPI could inhibit aggregation and improve digestibility, with glucose-based glycosylation showing better performance in intestinal digestion.

Summary: This study explored the interaction between proteins and corn starch with different amylose contents, and the effects on their physicochemical properties and in vitro digestibility. The results showed that protein hydrolysate inhibited the in vitro digestion of normal corn starch and high amylose corn starch, but promoted the digestion of waxy corn starch. The different distribution of water molecules during gel formation caused significant changes in the microstructure of the three types of corn starch after freeze-drying.

Summary: The combination of plant protein and polyphenol compounds is an effective strategy to improve the stability of protein emulsions. This study focused on the interaction between soy protein isolate (SPI) and tannic acid (TA) and studied their physicochemical properties and application in O/W emulsions. The results showed that the main non-covalent interaction between SPI and TA was hydrogen bond and van der Waals force. TA improved the emulsifying ability and reduced the interfacial tension of SPI, resulting in a stable emulsion with inhibited lipid digestion and oxidation.

Summary: The research used an in vitro infant digestive static model to investigate the digestibility of whey protein isolate-lactose (WPI-Lac). The results showed that WPI-Lac was completely digested after 5 minutes of gastric digestion, while WPI was not digested within 60 minutes. The beta-lactoglobulin of WPI-Lac was found to be similar to that of WPI at pH 3.0. After 60 minutes of duodenal digestion at pH 6.5, WPI-Lac was completely digested, and the alpha-lactalbumin of WPI decreased. The peptides identified were similar to 2 kilodalton (kDa) in conjugated protein, indicating a high level of protein degradation due to hydrolysis.

Summary: Processed sheep milks, specifically those that have been homogenized and heated, form curds with looser and more fragmented structures compared to unprocessed milk. This accelerates curd breakdown, protein digestion, and the release of protein, fat, and calcium into the digesta. Further observations during gastric digestion include coalescence and flocculation of fat globules in homogenized milks.

Summary: Heteroprotein complexes are formed through electrostatic interactions in a purely aqueous environment. This study investigated the structural and functional properties of soy protein isolate/lysozyme (SPI/LYS) complexes. Electrostatic complexation increased the surface hydrophobicity of the complexes, but it did not decrease the enzyme activity of lysozyme. The complexes exhibited flocculated structures and high dilution and NaCl reduced their size.

Summary: The effects of oxidized SPI emulsions on in vitro gastric stability and pepsin diffusion were investigated. The results showed that protein oxidation increased droplet size and decreased interfacial viscoelasticity. Pepsin diffusivity decreased due to the hindrance of oil droplets. After gastric digestion, protein hydrolysates formed a thick layer on the oil-water interface, reducing droplet size and free amino acid content. Protein oxidation affects interfacial protein adsorption and droplet distribution, impairing emulsion gastric digestion, which should be considered in the design of controllable delivery systems.
