　　首先要防止速凍食品在保存過程中多次解凍，再凍結，這樣會損壞食品的內部結構，食品的品質、口感、味道、營養(yǎng)就會下降，因此在保存過程中避免反復解凍，再凍結。其次盡量做到吃多少，加熱多少。如果一次吃不完，放回冰箱再凍結，以后再加熱，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.
