Potential Applications of Whey Protein Hydrolysates in Infant Formula Milk

Researchers from Ausnutria Dairy (China) Co. Ltd. have discovered that whey protein hydrolysates, industrial byproducts from the dairy industry, can enhance the bioactive potential of infant formula milk. The team, led by Yu Gao, incorporated whey protein hydrolysates into an existing milk powder formula, creating a new formula H. Through peptidomic analysis and mass spectrometry, they identified 126 bioactive peptides, including sleep-inducing, immune-modulatory, antimicrobial, and neuropeptides. These peptides bind primarily to their receptors via hydrogen bonding and hydrophobic interactions, highlighting the potential applications of whey protein hydrolysates in infant formula milk.
