Rapid Determination of Oligopeptides and Amino Acids in Soybean Protein Hydrolysates using High-Resolution Mass Spectrometry

摘要

Introduction - Soybean protein hydrolysates (SPHs), especially oligopeptides, have shown a variety of functional properties, including immunomodulatory and anti-oxidant effects. Soybean protein hydrolysate products have been used as functional ingredients in food, sports nutrition or clinical nutrition. However, the mixture is mostly undefined due to its complex nature, containing peptides and minor amino acids as well as small proteins.
