摘要：

The astringency in green tea primarily originates from gallate-type and non-gallate-type catechins. Epigallocatechin gallate (EGCG) is a gallate-type catechin, which has a strong astringency and is the most abundant catechin in tea. Unlike EGCG, epigallocatechin (EGC) has one fewer galloyl group on the C3 oxygen atom and exhibits a weaker astringency. Taking EGCG and EGC as representative catechins, this study investigated the effects of the galloyl group on their astringency. The interactions of EGCG and EGC with salivary proteins were qualitatively and quantitatively analyzed using fluoresce...
