Milk protein sensitivity is a major challenge in infant feeding, especially for infants who cannot receive adequate breastfeeding. Hydrolyzed milk protein is a mainstream way to address this difficulty. The aim of this study was to assess the effect of differences in whey protein concentrate (WPC) source and the degree of hydrolysis on blocking allergy and to analyze the possible mechanisms by which hydrolyzed infant formula (IF) blocks allergy through colony-metabolism-immunity response.

Transglutaminase cross-linking is a novel and specific modification method for black bean protein isolate (BBPI). This article investigates the effect of transglutaminase cross-linking on the structure and emulsification performance of heated BBPI.

Scanning electron microscopy showed that some areas of PVA/FUC nanofibers encapsulated with LP69-2 were locally broadened. Attenuated total reflectance-Fourier transform infrared spectroscopy and X-ray diffraction suggested that LP69-2 and polyphenol were successfully encapsulated in PVA/FUC electrospun nanofibers.

Human milk oligosaccharides (HMOs) are an evolutionarily significant advantage bestowed by mothers for facilitating the development of the infant's gut microbiota. They can avoid absorption in the stomach and small intestine, reaching the colon successfully, where they engage in close interactions with gut microbes. This process also enables HMOs to exert additional prebiotic effects, including regulating the mucus layer, promoting physical growth and brain development, as well as preventing and mitigating conditions such as NEC, allergies, and diarrhea.

Multispectral techniques show that WPC80 binds to FA and LAP mainly through hydrophobic interactions, and that energy is transferred from WPC80 to FA and LAP in a nonradiative form (FA/LAP); The combination of FA/LAP resulted in a change in the conformation and secondary structure content of WPC80, an increase in the absolute zeta potential of the system, and a shift in the particle size distribution towards smaller sizes. The compound system exhibits strengthened antioxidant properties and favorable binding properties.

To fully understand and develop the functional properties of EPS and to study the effect of EPS molecular weight on yogurt and its mechanism, the physicochemical properties of high molecular weight EPS-LH43, medium molecular weight EPS-LH13, and low molecular weight EPS-LH23, as well as the gel properties and protein conformation of yogurt, were determined and analyzed in this experiment. The results indicate that EPS-LH43 and EPS-LH13 are both composed of mannose, rhamnose, galacturonic acid, glucose, and galactose.

The results revealed that intact cells (IC), cell-free supernatant (CFS), and cell-free extracts (CFE) had potent DPPH (1,1-Diphenyl-2-picrylhydrazyl radical), hydroxyl, and superoxide anion radical scavenging capacities, among which CFS was the best. At the genetic level, we identified a strong carbohydrate metabolism capacity, an EPS synthesis gene cluster, and five sugar nucleotides in E3.
