Final freezing temperature had a greater effect than the freezing rate on frozen-dough stability. The major damage to frozen-dough stability seems to be the freezing of the yeast cell, but storage conditions also affect frozen-dough stability. In general, frozen dough were less stable if their storage temperature was lower than their freezing temperature. Thawing or partial thawing of frozen doughs followed by refreezing was harmful to frozen-dough stability.
