NOTES ON FREEZING AND STORAGE

1.Follow storage times indicated by the frozen food

manufacturer. Make sure that the packaging is undamaged.

2.Save energy: minimize opening of the door by storing identical food items together.

3.Items suitable for freezing: meat, poultry, fresh fish,

vegetables, fruits, dairy products, bread, baked goods, pre- cooked meals.

4.Items not suitable for freezing: lettuces, radishes, grapes, whole apples and pears, fatty meats.

5.When you freeze food yourself, pack it in appropriate quantities. In order to freeze food right through do not exceed the following quantities to best preserve the quality:

-fruit and vegetables: up to 1 kg,

-meat: up to 2.5 kg.

6.Blanch vegetables after washing and cutting them. (2-3 minutes in boiling water; then quickly cool them down in cold water. When you use a steamer or microwave oven, follow the operating instructions).

7.Keep packs dry in order to avoid them freezing together.

8.Freeze fresh food separately from already frozen foods.

9.Do not salt or season fresh food or blanched vegetables before freezing. Other foods may be lightly salted or seasoned. The intensity of flavour of some spices can change.

10.Use materials or containers specially suitable for freezing in order to avoid loss of quality during defrost.

11.Write contents and date of freezing on the packs. Do not exceed the storage time indicated in order to preserve quality.

12.Do not freeze bottles or cans with carbonated drinks as they might burst.

13.Take out as much food as is immediately required for thawing. Prepare it as soon as possible after thawing.

WHEN PURCHASING FROZEN FOOD

1.Make sure that the packaging is undamaged (damage may have caused the food to deteriorate). Bulging packs or packs which are marked with liquid stains could have been improperly stored and may have been partially thawed.

2.Leave frozen food purchases until last and transport the items in insulated bags.

3.Place the items in the freezer as soon as possible.

4.Do not refreeze partially thawed food. Consume it within 24 hours.

5.Observe the date of consumption and storage information.
