Impact of flavonol extracts derived from green tea or targeted flavonols as secondary ingredients on intestinal glucose transport.

ABSTRACT: The purpose of the current study was to examine the effect of adding secondary ingredients such as green tea derived water-soluble polysaccharides (GTP) and flavonol aglycone rich fractions derived from cellulase treated green tea extract (FVN) into catechin rich green tea extracts (GTE) on wheat starch digestion and intestinal glucose transport using in vitro digestion with Caco-2 cells. Co-digestion of wheat starch with GTE (16.88 g L^-1) or GTE + GTP + FVN (16.69 g L^-1) appeared to promote starch hydrolysis compared to control (15.49 g L^-1). In case of major flavonoids, addition of epigallocatechin gallate (EGCG), EGCG + myricetin (M) into wheat starch significantly increased the digestion of starch into glucose. Glucose transport rate decreased by 22.35%
