Effects of different freezing rates on the freezing characteristics of Ctenopharyngodon idellus C. et V fillets;

Effects of different freezing rates on the physicochemical and sensory qualities of Silurus meridionalis fillets;

Effects of freezing rate and frozen stored temperature on freeze denaturation of Hypophthalmichthys molitrix muscle protein;

Applying to slow freezing and liquid nitrogen quick freezer by the fashion of spray and flowed state,the effect of freezing-rate on polyphenoloxidase(PPO) and peroxidase(POD) activity in Tricholoma matsutake was studied.

In order to maintain the freshness,color,deliciousness and flavor of foods,the carbon dioxide fast freezing machine has been developed on basis of liquid carbon dioxide spray refrigerating principle,and food may swiftly pass through the ice crystal band by using this machine.

It means that the fast freezing of this shaft is actual.
