Olivera and Salvadori (2009), suggested that slow freezing
formed large size ice crystals causing the disruption of dough gluten
network during freezing. Meziani et al. (2012) shown the
dependence of fermentation activity and integrity of the gluten
network with freezing rate, which controls size and location of
ice crystals resulting in research of a compromise between freezing
rate nor too fast to reduce yeast viability, nor too slow to form large
ice crystals that could perforate gluten network.
