The quality of frozen food relates to freezing processes, in which different methods have different freez-ing rate. Power ultrasound freezing is using ultrasound to assist food freezing by generate cavitations in the aqueous phase. High pressure method can greatly aid freezing process and improve product quality. The main advantage of high-pressure freezing is to form small and homogeneous ice crystals upon pressure release, and thus reduce the dam-age to the inner texture and structure of the food. The function of the antifreeze proteins is to lower the freezing tem-perature and suppress the growth of ice nuclei, thus inhibiting ice formation and altering the ice habit and growth rate.Ice nucleation active bacteria can reduce the degree of super cooling and catalyze ice formation. This paper overviews several freezing technologies such as ultrasonic freezing, high pressure freezing, and the methods of using antifreeze proteins and ice nucleus bacteria freezing proteins.
