Reduction of Catechin Astringency by the Complexation of Gallate-Type Catechins with Pectin [PDF]
Bioscience, Biotechnology, and Biochemistry, 2005 The reductive effect of pectin on tea catechin astringency was investigated by using a taste sensor system and (1)H-NMR spectroscopy. The sensor analysis revealed that the astringency of gallate-type catechins (EGCg and ECg) was reduced by the addition of pectin, whereas that of non-gallate-type catechins (EGC and EC) hardly changed.
