Most of these studies were interested to bread dough produced from a basic formula. This work is distinguished by the complexity of sweet dough formulation (high fat and sugar content) and use of cryogenic immersion to achieve freezing rates ultra-fast. These factors influence intrinsic dough properties. The milk and lipids contained in sweet dough which can contribute to cryoprotection,while sugar enhances yeast’s growth before freezing (Meziani et al., 2012; Wolt and D’Appolonia, 1984). To elucidate this point,frozen sweet doughs were prepared by in the same conditions
different freezing treatment. Similarly, use of natural additives like whey proteins, surfactants and enzymes are also gaining importance to control the water redistribution problems in the frozen doughs’ structures (Asghar et al., 2011). No study on freezing rate and formulation effect on sweet dough properties with complex recipe have been published. Kougelhopf matrix was chosen in this study for its manufacturing process similar to that of bread and complexity of its dough recipe.
