tea catechins may_differ_from_flavonol_glycosides_in Rough or puckering versus smooth or velvety astringency予備的
範囲: Artificial oil-body in-vitro assay
注記: The model is not a direct human demonstration of independent astringency subqualities.
Artificial oil-body surfaces differed after catechin versus rutin interaction and were interpreted as rough/puckering versus smooth/velvety astringency.
限界: In-vitro physical model does not directly establish human perceptual subqualities.
