摘要
The in vitro fermentation selectivity of purified galactooligosaccharides (GOS) after their conjugation with bovine beta-lactoglobulin (beta-LG) via the Maillard reaction and a subsequent simulated gastrointestinal digestion was evaluated. Changes in human faecal bacterial populations, lactic acid and short-chain fatty acids after 10 h and 24 h of fermentation of the digested beta-LG:GOS conjugates revealed that this mixture of glycated peptides had a similar bifidogenic activity to the unconjugated GOS. These findings could open up new applications for Maillard reaction products in the functional foods field. (c) 2011 Elsevier Ltd. All rights reserved.
