Phenolic compounds comprise simple polyphenols together with
highly polymerized tannins. The former group includes benzoic
acid derivatives, monomeric flavanols, flavonols, and flavanones,
while the latter includes polymerized flavan-3-ols procyanidins).
Persimon tannins may be either of low molecular weight and
hence water soluble, and astringent, making the fruit not edible
at harvest time; or of high molecular weight and thus water insoluble,
and non astringent, making the fruit edible at harvest time
(Giordani, Doumett, Nin, & Del Bubba, 2011).
The persimmon fruit may be used for
