首先要防止速冻食品在保存过程中多次解冻，再冻结，这样会损坏食品的内部结构，食品的品质、口感、味道、营养就会下降，因此在保存过程中避免反复解冻，再冻结。其次尽量做到吃多少，加热多少。如果一次吃不完，放回冰箱再冻结，以后再加热，效果就更差。

The first thing is to prevent several times for thawing and freezing again, if not, the quality, taste and nourishrrent will be worse. So the better way to keeping is how much you want to eat, than how much you heated. If you put the left food to the refrigerator, it will break the food tasting.
