Yes, I've read that the puckery substance precipitates out when the
persimmon becomes ripe. What I'm wondering is whether the soluble puckery
substance cross-links something in your saliva with something in the
persimmon, producing an insoluble material that makes your mouth feel like
it's full of cotton. Polyphenolic substances such as tannins are known to
undergo cross-linking reactions like what I described. The ripe persimmon
may have something (enzyme, binding substance, ..?) that reverses the
reaction. Maybe someone at one of the agricultural universities (Purdue?)
would like to figure out what's going on.
