2. The purchased frozen food should be stored in the freezer as soon as possible.

Before freezing food, you should wrap the food well, so as to keep the moisture and flavor of the food better, and then put the food into the freezer.

Tofu and fresh vegetables must not be put in the quick-freezing room, otherwise they will be frozen.

If you want to thaw frozen food such as fresh fish and meat, you can put it in the freezer a few hours before cooking. If you want to thaw food quickly, you can put these foods in plastic bags and brew them with tap water.

Generally speaking, food should not be frozen after it is completely thawed. If the food is still frozen hard or has ice crystals, it is not a problem to freeze it again. However, the quality and taste of this kind of food may be reduced, and it should be eaten as soon as possible because it cannot be preserved for a long time.
