Abstract
Carrot (Daucus carota) antifreeze proteins have strong anti-recrystallization ability and potential uses in food industry. In this study, the effects of carrot concentrated protein supplementation containing 18.3% carrot antifreeze protein on the fermentation capacity of frozen dough were evaluated. Adding carrot concentrated protein to frozen dough increased the retention capacity of the dough, decreased mortality of the yeast, caused a thermal-hysteresis phenomenon during freezing–thawing cycle, and retarded the crystal forming. The application of carrot concentrated protein in frozen dough was proved to be a promising improver for the frozen dough fermentation.
