retrogradation
A reversal to a simpler form, such as a physical
reaction involving vegetable adhesives,
characterized by a reversion to a simpler
molecular structure. An example of retrogradation
would be a change in starch pastes from low to
high consistency upon aging, and, in extreme
cases, a separation of more-or-less solid gel from
the aqueous solution. (309 )
