水果速冻保藏研究进展

Advances in the Studies of Quick-freezing and Frozen Storage of Fruits

综述了水果速冻和冻藏研究领域中,水果速冻分类方法;冷冻速率与细胞冰晶体的分布、大小和细胞结构变化的关系;冷冻-解冻和细胞结构变化的关系;与水果质量有关的酶活性变化,果肉色泽、风味和抗坏血酸的变化;低温玻璃化贮藏水果的优点以及水果速冻和玻璃化保存期间低温断裂的问题。

The subject in the field of quick freezing and frozen storage of fruits are discussed as follows: the classification of frozen fruits j the relationship between freezing rate and crystal distribution, size and structural changes of cells ;the relationship between freeze-thaw and structural changes of cells; the changes related to table quality of fruits in enzymatic activity of cells, coloration, texture, flavor and ascorbic acid of flesh; the advantage of glassy storage fruits. Finally, the freeze-cracking during ultra-freezing and glass frozen storage are reviewed as well.
