What problems can arise with repeated freezing?
The biggest concerns when freezing thawed food are usually of a health-related nature: during the slow thawing and warming of food, it is possible for harmful germs to settle on the products. This can spoil the food and become a health hazard for those who eat it. Depending on the type of product, the risk of health damage from repeatedly defrosted food is relatively low.
The product groups described below vary greatly in terms of the germ contamination to be expected:
  • Prepared dishes (home-cooked or finished product).
  • Raw food.
  • Food consumed without previous cooking.

Does the product quality suffer during repeated defrosting?

The answer to this question is clearly yes. Freezing damages the cell structure of the food, which means that fruit, for example, is often mushy after thawing. This effect is intensified during the second freezing and re-thawing process, which is why the food often becomes unsightly. The taste of many products also suffers from repeated thawing.

Refreezing prepared dishes

Refreezing prepared dishes

No matter if you prefer a ready-made frozen dish or food prepared at home: You can easily refreeze leftovers from your already defrosted meals if the dish is reheated sufficiently before consumption. Possibly contained harmful germs are killed off in the oven, cooking pot or microwave, so there is no health hazard when eating. Before repeatedly freezing the food, you should make sure that it is not left unchilled for more than two hours. In this way you can additionally prevent the formation of germs. Please note that ready-made meals in particular lose a lot of their aroma during repeated thawing.

Refreezing raw food

Do you want to cook the defrosted food before eating it? Then there is no health hazard from repeated freezing. If you want to eat fruit or vegetables raw, it is important to make sure that no germs can settle on the food during the first and each subsequent thawing: The fruit or vegetables must always remain chilled, i.e. defrost in the refrigerator. Repeatedly thawed animal products should not be eaten raw due to the health hazard in case of germ contamination. Due to their high water content, the structure of most fruits and vegetables suffers so much that the rethawed fruits look unappetizing.

Refreezing unheated food

Frozen foods that are not heated before consumption must not be left unchilled for more than two hours if you want to freeze them again. Otherwise the risk of increased germ contamination is high. For the sake of your health, however, you should not refreeze such food, especially if it contains ingredients of animal origin (e.g. ice cream or pastries).
