The use of temperatures of -0.4°F (-18°C) or colder to store food means that the food can be kept for longer periods than when refrigeration temperatures are used. This is because the growth of bacteria, molds and yeasts are stopped, and chemical and physical reactions are severely restricted at such low temperatures.
Frozen Food Care
For Best Results:
- Choose only high quality foods that freeze well.
- Store at -0.4°F (-18°C) or colder. Take care to maintain this low storage temperature, eg try to avoid opening the freezer door unnecessarily. If your ice cream is soft you are running your freezer too warm.
- Leave space at the top of containers, glass jars or plastic bags containing liquids or semi-solid foods. These expand as they freeze. Usually 1 – 2” (20 – 50mm) head space is recommended. Seal. Ideally, remove all the air from the package after food is frozen.
- Packages or containers of solid foods should have the air removed from them and be sealed tightly before freezing.
- Use the ‘Fast Freeze’ function when freezing fresh food. This helps to speed up the freezing process, giving optimum freezing results. It is recommended that the function is activated approximately 2 hours before required.
- Freeze immediately or as quickly as possible. Freeze only small quantities of food at any one time. For best results we recommend that only 2.2lb (1kg) of food be frozen per 6.6gal (25L) or 0.88 cubic feet of freezer storage volume at any one time. (About 6.6lb (3kg) in small freezers and 8.8lb (4kg) in larger freezers). For faster freezing in ActiveSmart™ models, we recommend that fresh food is placed at the top of the freezer compartment close to the air vent.
- Thaw foods preferably in a refrigerator, or using a microwave oven or multifunction oven.
- Keep a constant turnover of food. Use older items of food first and do not exceed recommended storage times.
- Use good quality freezer proof packaging to maintain food quality.
- If food is only covered in plastic film place inside a freezer-proof plastic bag.
Recommended Freezer Storage Times
These times should not be exceeded.
|Months||Type of Food Stored|
|1||Bacon, casseroles, milk|
|2||Bread, ice cream, sausages, pies — (meat and fruit), prepared shellfish,oily fish|
|3||Non-oily fish, shellfish, pizza, scones and muffins|
|4||Ham, cakes, biscuits, beef and lamb chops, poultry pieces|
|6||Butter, vegetables (blanched), eggs whole and yolks, cooked crayfish, minced meat (raw), pork (raw)|
|12||Fruit (dry or in syrup), egg whites, beef (raw), whole chicken, lamb (raw), fruit cakes|
Meat, Poultry and Game
- Do not try to freeze more than 2.2lb (1kg) of meat per 25qt (25L) of freezer storage volume at any one time. Meat must be frozen quickly in order to maintain its texture.
- Do not stuff poultry before freezing.
- Red meat can be cooked from frozen, or from the partly or completely thawed states. Remember to allow extra cooking time if cooking from frozen.
- Always thaw poultry completely before cooking
- Fish is best frozen commercially. If, however, you do want to freeze fish at home, make sure the fish is very fresh and of high quality.
- Clean, scale and preferably leave whole. All fish should be wrapped in two layers of packaging as depending on the type of fish, odors and flavors can be readily transferred either to or from it. Seal well.
- For best results, cook from either the frozen or partly thawed state.
- Choose high quality, mature, and ready to eat fruit. Preferably select varieties recommended for freezing.
- Avoid unripe and over-ripe fruit.
- The way fruit is packed depends on how it is to be used. Fruits packed in syrup are ideal for desserts, whereas fruits packed without sugar are better used for cooking. Most fruits can be stored for 8 – 12 months.
- Most vegetables freeze well, although ‘salad’ vegetables lose their crispness. Other vegetables, eg celery, onion and tomatoes, should only be used in cooked dishes as they soften on freezing.
- Freeze only high quality, mature, ready-to-eat vegetables.
- Sort and discard any vegetables that are damaged.
- It is necessary to blanch most raw vegetables prior to freezing.
- Blanching involves a short cooking period during which vegetable enzymes are destroyed. If these enzymes are not destroyed they cause undesirable physical and chemical changes during freezer storage.
- Vegetables can be blanched in boiling water, steam or microwave oven. If using boiling water, boil vegetables for 2 – 4 minutes and cool quickly.
- In general, frozen vegetables are best cooked from their frozen state.
Prepared and Cooked Foods
Most cooked foods can be frozen but it is not recommended to freeze the following: Cooked egg white, custards, cream fillings and milk puddings, gelatin or jelly-like dishes, mayonnaise and similar salad dressings, meringue toppings. These tend to separate on thawing.
