In vitro evaluation of the effects of protein–polyphenol–polysaccharide interactions on (+)-catechin and cyanidin-3-glucoside bioaccessibility

The bioaccessibility of cyanidin-3-glucoside and (+)-catechin in model solutions when β-lactoglobulin (β-LG) and pectin/chitosan are present was investigated using anin vitromodel simulating gastrointestinal conditions.
