In order to avoid food spoilage, several basic actions should be performed that everyone needs to know about. After these manipulations, the food retains not only freshness, but also taste. The main rule, which is emphasized, is the observance of the required storage temperature of products. Nutritionists say that in order to comply with the principles of proper nutrition, food should be placed in the refrigerator in a certain way. And experts in the field of household appliances claim that each shelf provides suitable conditions for a particular category of products.
What is suitable for berries and vegetables?
Preserving vitamins in these products is an important task for any housewife, because not everyone knows what exactly is suitable for her set. Storage temperature for twigs of grapes, raspberries and currants, peaches, apricots, plums - from 0 to -2 degrees. Next come mushrooms, broccoli, beans, herbs, onions and cabbage, radishes and turnips, garlic. They will feel comfortable if the value does not go into minus.
Storage temperature from 0 to +3 degrees is suitable for such products:
- Cherry.
- Sweet cherry.
- Blueberries
- Oranges
- Tangerines.
- Kiwi.
- Beet.
- Zucchini.
Harvested spicy herbs may well be in the same storage conditions. A temperature of +3 0 C can be detrimental to avocados and cranberries. If for short-term storage, then they do not deteriorate and do not lose their qualities at indicators up to +6 degrees. But do not confuse the short-term storage procedure with several months.
Not every refrigerator has a lot of free space to keep everything you want. The storage temperature in this run from +12 to +17 is suitable for many exotic fruits - bananas, pineapples, coconuts. In addition, home cucumbers will not deteriorate if they are stored in the same way.
Temperature mode
They recommend sticking to the following range for products:
- From +12 to +14 0 C for basil.
- Lemon - from +5 to +12.
- Bell pepper - +8 to +11.
- From +7 to +13 - eggplant.
- Watermelon does not deteriorate to +20 degrees.
- Pomegranate and blackberry - from 0 to +7.
- Potatoes and tomatoes should not be kept in the refrigerator, they do not deteriorate and do not lose their quality to +21 degrees.
- A pear from the south may not deteriorate even at +5 0 C, but grown in other conditions should not be stored like that.
It is not always convenient to store such products in the cellars, because the temperatures there are high. So that berries and vegetables do not lose their qualities during freezing, it is worth adhering to a regime of -19 degrees. They can be stored for a long time, but each one will have to be periodically examined for damage, otherwise from one copy the entire stored volume will become unusable.
Frozen storage periods reach one year or more. But in other conditions, this period is reduced. Of course, with the right conditions, you can eat bought berries and vegetables for a month. Shelf life at temperatures below 0 will increase.
Mode
A correctly selected mode is undoubtedly important. It should be adhered to throughout the shelf life. For example, if you keep bananas at +20 0 a week, and then put them on the shelf in the refrigerator, where -1 0 , it is not a fact that they will look appetizing. All these nuances should be considered in advance so that berries, fruits and vegetables do not spoil.
What products should create the best conditions?
What storage temperature is suitable for meat? Freshness will be visible if, within 24 hours, this product is at a temperature of no higher than +3 degrees. When defrosting a large piece of pork, it’s easy to preserve its suitable qualities if put in a room with +7 0 C and left there for up to two days. At -18 0 C, meat is stored for up to one year and does not lose its properties. Two days at +3 0 C are reserved for sausages, sausages, smoked ham, boiled pork.
Experts believe that all sausages can be frozen, the shelf life reaches 10 days, but subject to a regimen of at least -11 0 C. Salo can lie in the freezer with simple rules:
- Hermetic packaging.
- Temperature is not lower than -20 degrees.
- Fresh.
In this case, within 9 months it will not lose its qualities. Storage at room temperature reduces the freshness of many products. Within three days at +7 degrees the following products will remain usable:
The meat of any bird will be stored for a long time if it is frozen in the refrigerator at -20 degrees.
But such force majeure, such as, for example, de-energizing the refrigerator, can happen. In this situation, the regime is violated and it is already difficult to talk about the permitted time and the possibility of use. Therefore, all products must undergo a visual inspection.
Milk products
Many families have such products on their daily diets, but what is the optimal storage temperature? One fact applies to all dairy products - they are perishable. Fresh milk, cream are stored at +6 no more than 7 hours. A boiled milk at +8 0 C for up to 24 hours. Dry milk products in sealed packaging will lie for about 5 months with a thermometer reading not higher than +2 ° . An open can of condensed milk should be consumed within three days, if in the refrigerator from 0 to +1 ° C.
Margarine and butter with positive indicators of 6, 7, 8 0 C will retain freshness for up to 7 days, in the freezer this period is 10 months. Ice cream does not lose its qualities, having lain for six months at -30.
Cheese is a unique product that is quite normally stored at + 10 ° C. Curd products should not be left warm, it is better to put in a refrigerator on a shelf with a temperature from 0 to + 1 ° C.
Based on this, the purchase should be guided by the date of manufacture. Any dairy products should not have a long shelf life, this indicates the presence of preservatives in the composition. Observing the storage regime, the risk of poisoning is minimal.
What happens to fish?
The consumption of fish and seafood benefits the whole body as a whole. But if the caught product is not stored properly, then it can be dangerous. Fresh fish should not lie in conditions above + 2 ° C, other indicators for it are not tragic, but no more than 48 hours.
When frozen, its shelf life rises at -17 ° C to 3 months, at -7 ° C - 14 days. When shopping, you should understand that this is a perishable product, so chilled options are not always contained in the right conditions. Smoked fish will lie for 72 hours or more, if the temperature is not above +1 ° C, and if it is frozen, then the period can be extended by 10 times. In this case, you need to properly remove the product from this state - thaw at +6 ° C.
By creating conditions from -3 to -6 ° C, you can save up to one month both whole carcasses and balyks of the following types:
- Cold smoked fish.
- Herring.
- Mackerel.
- Sigi.
Pickled products are good when conditions are created for it from 0 to -2, dried - 12 months at - 7 ° C. Some living inhabitants of the seas and rivers are stored for up to several days at + 3 ° C. Not all stores have this product that meets specified requirements. It is also worth visually assessing - frozen fish should not have a yellow coating. This sign can speak of old age and unsuitability of food, which is especially applicable to red varieties of sea inhabitants.
Often fish is sold in ice chips. Many people think that this is a fresh product, but this is not always the case. If the fish was frozen, after which it was removed from this state and laid out on ice, as if fresh, then it should not be stored for more than 48 hours. In addition, defrosting is unacceptable at temperatures above + 7 ° C. Before buying, it is worth clarifying all the details.
What should not be forgotten?
All products have their optimum performance and shelf life. Violating them, a person exposes his body to danger. If there is no confidence in the products in the store, you should refuse to purchase. Fresh chicken egg, placed in the refrigerator, where the temperature is -3 0 C, will lie for up to 6 months. Eggs are healthy, but you should not eat them raw anyway.
The big problem of bread is callousness, but if it is stored at -6 ° C, then the problem does not appear. Honey is a useful product, it will not lose this quality, remaining in conditions of + 10 ° C. But it should not just stand indoors. It is important to exclude direct sunlight from the best. It is optimal to store honey in a closed and dry place. If it is a can, then the lid should be closed. Then honey will retain its palatability and remain useful. Salads cannot be stored for more than 3 days at a temperature of +3 degrees.
Conclusion
So, we examined at what temperature you can store different foods. All products must be fresh from the start so that simple storage rules apply to them. Do not violate regimes and periods, otherwise there is the likelihood of food poisoning.
