影响肉类食品冷冻质量的若干因素

Research of Influence Factors of Freezing Meats' Quality

在不同冷冻条件下冷冻肉类食品均有不同的品质变化。冻结温度、冻结曲线、最大冰晶生成带速度、冷冻中的玻璃化转变以及转变温度都对食品组织结构、蛋白质冻结变性、食品外观、风味、营养等构成直接的影响。

The quality of frozen meat foods are subjected to various changes under different frozen couditions. The foods freezing time the freezing time-temperature curve, the fastest velocity of ice-crystal produce＇s zone, the glassy-transform and temperature-transform in freezing will have direct influence on food＇s structure,protein＇s freezing denaturation, apprearance ,flavor and nutrition.
