Frozen goods is long stored and can help out in a situation, when there is no an opportunity to go shopping in shop. But not all products are subject to freezing as after defrosting they will be unsuitable in food.
Several decades ago hostesses could see a frozen goods only on counters of shops and then it was considered as an unusual innovation, and now each person can freeze products in the fridge. The principle of the majority of home freezers is identical, but there are rules of freezing of products which the hostess has to observe каждя.
Frozen goods has an expiration date
Though the expiration date of the frozen product usually surpasses an expiration date of storage fresh ten times, but nevertheless it is. Products which lie longer than the designated time have to be utilized, otherwise there is a risk to get poisoned. The maximum expiration dates for different products differ:
meat (pork, mutton, beef, horse-flesh) - about half a year; chicken entirely - about one year, parts - up to 9 months; ready-to-eat meals (including soups) - no more than 3 months; a fatty fish - up to 3 months, other - about half a year; mushrooms fresh - up to 8 months, boiled - about one year; seafood - 3-4 months; berries - about half a year; nuts - up to two years; greens - no more than a month; a bakery goods - no more than three months.
It is possible to freeze also vegetables with fruit, but they also have various periods of storage:
the majority of fruit and vegetables - about one year; tomatoes - up to two months; pepper - 3-4 months; apples - 4 months; apricots and peaches - 4-6 months; pumpkin - up to 10 months; cabbage, cucumbers, a celery - don't recommend to freeze.
In order that the expiration date of a frozen goods was maximum, it is necessary to maintain constant temperature in the freezer and not to allow even partial thawing. It is necessary to store products a la carte not to defreeze every time large volume.
To prolong meat periods of storage, it is necessary to freeze its dirty. Water reduces storage of meat products twice.
Before freezing chicken entirely, it is necessary to remove giblets as chicken and giblets have different periods of storage from her.
Package in which the frozen products will be stored has to be sealed.
In a frozen goods of a bacterium aren't destroyed
There is a myth that freezing is capable to kill pathogenic bacteria, but scientists disproved it long ago. On a surface of a fresh and frozen goods the same bacteria are found, only in the second case they become inactive. At long thawing of a bacterium we are capable to become more active and develop further, causing damage of a product.
In order that bacteria had less opportunities for development, it is necessary to defreeze products correctly. For this purpose the frozen products need to be got from the freezer, to put on a plate and to put on the lower shelf of the fridge before full defrosting. Such way is considered the safest. A defrosting in the open air not the best option as in this case bacteria, especially on meat, fish and a bird can become more active.
Frozen goods contains the same amount of vitamins, as fresh
One more popular belief - a frozen goods loses the most part of useful vitamins and substances. It is possible both to agree with it and to argue. For example, ""shock"" freezing (it is used on big productions) is really capable to destroy a number of useful substances, but not all. And here the home freezer keeps the majority of vitamins at all.
In order that products from the freezer were the most useful, it is necessary to buy them for freezing during a season (for example, winter fruit will be for certain full nitrates, and summer - no), and to defreeze by means of a steam bath, then with water the necessary vitamins and minerals won't leave.
Defrosted products can be frozen repeatedly
Repeated freezing isn't admissible as it not only is harmful, but also has strong impact on gustatory qualities of products. But there are situations when the defrosting occurs irrespective of the person (for example, at blackout in the house). It is in that case admissible if the product lay on air 2 hours before return to the freezer. An exception - meat, fish and a bird, these products is better to prepare at once.
It is possible to freeze not all products
It is considered that it is possible to freeze anything, but actually it not so. There is a list of products which can't be subjected to freezing:
- Shell eggs. In general eggs can be frozen, but only not in a shell as liquid in protein when freezing extends and the shell bursts from what when defrosting the pieces can get to a dish. Also there is no sense to freeze boiled eggs as they will become ""rubber"". It is the best of all to freeze fresh eggs, previously having broken them in a container.
- Dairy products. When freezing, milk, sour cream, mayonnaise, yogurts change the structure and when defrosting are displaced. It is possible to freeze such products in case further they aren't used in pure form.
- Ready food breaded. At a defrosting the breading crackling earlier will turn into unattractive unappetizing porridge.
- Watery fruit and vegetables. When freezing, liquid in these products crystallizes because of what when defrosting they will turn into inedible puree. Enter the list of such vegetables and fruit: squash, cabbage, cucumbers, pear, eggplants and some other.
- When defrosting, cheese will become friable and will begin to collapse on small pieces.
- Canned food. Liquid when freezing will extend that can cause explosion banks. It is necessary to remove after that long, and perhaps it is necessary to throw out other products which were near canned food.
- To hard alcoholic drinks in the freezer there will be nothing terrible, but here to champagne, beer, wine there can be the same, as to canned food.
- Boiled rice. If there was a large number of rice, then it is better to use it at once, but not to freeze as after defrosting it will turn into sticky porridge.
The freezer - the real rescue for hostesses. But it is important to know what products can be frozen and what it is impossible and also expiration dates of any given frozen goods.
