摘　　要：冷冻是抑制食品腐败变质,延长食品保质期的有效手段。但传统冷冻方法易形成大而不规则的冰晶,导致食品品质的劣变。找到合适的冷冻方式抑制冷冻导致的食品品质劣变是食品冷冻行业亟待解决的问题。等容冷冻是一种新兴的冷冻技术,它利用等容环境中,冰晶的形成增加环境内压,降低液相的凝固点,使得液相处于过冷的环境中,抑制处于液相中的食品中冰晶的出现,降低冰晶生长对食品组织的破坏。该文对等容冷冻的设备、基本原理以及其在食品贮存方面的应用进行了综述,以期为等容冷冻在食品贮存中的应用提供参考。Freezing is an effective means of inhibiting spoilage and prolonging the shelf life of food products.However,traditional freezing methods are prone to the formation of large and irregular ice crystals,which can lead to the deterioration of food quality.Finding a suitable freezing method to inhibit the deterioration of food quality caused by freezing is a pressing issue for the food freezing industry.Isochoric freezing is an emerging freezing technology that uses an isochoric environment where the formation of ice crystals increases the internal pressure of the environment and lowers the freezing point of the liquid phase,leaving the liquid phase in a supercooled environment,inhibiting the appearance of ice crystals in the food in the liquid phase,and reducing the damage to food tissue caused by ice crystal growth.This paper reviewed the equipment,basic principles,and applications of isochoric freezing in food storage,to provide a reference for the application of isochoric freezing in food storage.
