Optimization of rennet coagulation technology in the process of production of rennet casein

The effect of the amount of rennet added,rennet coagulation temperature and time on the technology of rennet casein were studied.The optimal rennet coagulation processing parameters of the production of rennet casein were determined by sensory evaluation on the process of coagulation.The results showed that the coagulation temperature and time have a significant effect on rennet coagulation status of rennet casein production.The optimal conditions of rennet coagulation were: the addition of rennet was 0.078%,the temperature of coagulation was 32 ℃ and coagulation time was 28 min.The physicochemical properties of rennet casein produced under this condition were similar to those of commercial rennet casein.
