The freezing rate plays an important role in the final quality of
frozen product, two opposite effects are observed. A high freezing
rate allows the formation of ice microcrystals, which do not affect
the gluten network integrity, which reduces physical damage
(disturbance and dehydration of gluten network) induced by
freezing, ultimately to the extent that the starch granules appear
to be associated with the network gluten (Angioloni et al., 2008).
Nonetheless, rapid freezing might fatally compromise the yeast
activity.
