摘要
Phenolic compounds (PCs) are frequently present in foods. However, little is known about the effect of PCs on enzymatic digestion process of food proteins and their products. In this study, the effect of gallic acid (GA) on in vitro digestion of beta-lactoglobulin (beta-LG) was investigated as a model system for analysis of the interaction between PCs and food proteins. GA showed no effect on the initial rate of beta-LG digestion. However, after 1.5 h of digestion, the observed degree of hydrolysis of beta-LG was lower in the presence than in the absence of GA. The peptides released from beta-LG were characterized by LC/IT-TOF-MS and thirty peptides were identified. In particular, four new peaks were obtained following in vitro digestion of beta-LG in the presence of GA. Met(7), Met(24) and Met(145) in the peptides corresponding to these peaks were oxidized to methionine sulfoxide residues. (C) 2012, The Society for Biotechnology, Japan. All rights reserved.
