Egg white peptides are a series of compounds composed of amino acids. In addition to their nutritional functions, they play an irreplaceable regulatory role in human physiological activities. Using bioengineering technology, various peptides extracted from natural proteins can be widely applied in pharmaceuticals, health products, and food to improve bodily functions, regulate physiological activities, and enhance the ability to prevent, resist, and recover from diseases from a nutritional perspective.

Albumin peptides are multi-component peptide substances extracted from high-quality natural proteins using directed enzymatic cleavage technology, with a molecular weight controlled below 2000D.

Regarding peptide absorption, in addition to the free amino acid transport system, the small intestine has a specific oligopeptide transport system. Recent experiments by Roberts PR have shown that small peptides (2–3 amino acids) and large peptides (10–15 amino acids) in the diet can be fully absorbed through the intestines and act as bioactive peptides, eliciting biological effects at the tissue level.
