[Adsorption kinetic study of the interaction between human salivary alpha-amylase and the polyphenoles from the black/green tea].

OBJECTIVE To explore the driving force of the oral astringency produced by the interaction of theaflavin (TF) and epigallocatechin-3-gallate (EGCG) to human salivary a-amylase(HSA). METHODS The constants of the rate, equilibrium of reaction (k(a), k(d), K(A), and K(D)) and Langmuir, Freundlich adsorption isotherm (K(L), K(f), and Mm) were determined by… CONTINUE READING
