What is the optimum temperature for the freezer?

European standards assume the presence of several types of freezers in the refrigerator. It is important for careful storage of products, and also matters from the point of view of energy conservation. Standards of the Russian Federation imply a temperature in the chamber from -18 to -24 degrees, the European approach is more correct.

Food Storage

Different temperature regimes can affect the quality and duration of storage of various products in different ways. Some products can maintain their suitability of consumption at different temperatures, for others the longevity directly depends on how the temperature in the freezer is set during storage. An example of the second type of product is margarine, which retains its properties from 10 to 90 days, depending on the temperature conditions of storage.

It is not difficult to calculate that for individual products lower temperatures significantly increase the shelf life. When purchasing large quantities of individual goods, it is advisable to organize the storage temperature as low as possible, for this you need large cold stores with an appropriate temperature. According to European standards, the temperature in the freezer is divided into the following classes:

• about 0 degrees( 0 stars);
• minus 6( 1 asterisk);
• minus 12( 2 asterisks);
• minus 18( 3 stars);
• below minus 18( 4 asterisks).

The presence of different cameras allows you to choose the refrigerator that best suits your needs. You focus on the classes of freezers, which helps to choose the optimal model for storing food.

Meat in the freezer

The overwhelming majority of food stored in the refrigerator compartment is meat. At temperatures below 14 degrees, the shelf life of meat products can reach up to six months. Meat dishes in the freezer class 4 stars can be stored for up to three months. The storage of frozen meat at a temperature of about 8 degrees below zero is reduced to one and a half weeks.

Achieving an optimal shelf life will help to achieve the correct temperature in the refrigerator compartment. If long-term storage of meat products is planned, the temperature should be below minus 14 degrees, and the class of the freezer can not be less than 3 stars. With plans for eating meat in a short time, a refrigerator compartment with a temperature of about 8 degrees below zero is quite suitable. It should be borne in mind that maintaining cold requires high energy costs, so it is necessary to calculate the economic feasibility.

Chicken eggs in the

refrigerator. The lower the temperature, the longer the shelf life of products. This rule is known to many, but in some cases it does not work, as is the case with the storage of chicken eggs. The optimum temperature for storage is the interval between 0 and minus 2 degrees, in this mode, eggs can store up to three months.

It is believed that an egg can be stored for a long time even at room temperature, but this is not always true. Chicken eggs often go dry, leading to an unpleasant odor. At low temperatures, such a product can simply burst, it is the temperature minus 2 degrees that is optimal. For the storage of this type of food suitable cameras class 0 stars.

Storage of fish products

Fish is more picky for the preservation of its taste. The best is the temperature in the freezer, corresponding to 3 asterisks. Different species of fish vary in shelf life, freshwater species can be stored for up to six months, sea - no more than four months. If the temperature in the freezer is about 10 degrees, the longevity of fish products is halved. The shelf life of finished fish products is reduced by half.

Medicines in the freezer

Certain types of drugs should be stored at low temperatures, not always conventional freezers meet all requirements. Specialized freezers have precise temperature control, noise and light alarms, and special operating modes. Such refrigerating chambers do not fall under the generally accepted classification, since there are many nuances of their work.

The cost of refrigerators with such cameras is much higher, but what other camera is capable of creating temperatures below 30 degrees. The quality of storage of medicines should be taken care of as much as possible; for areas with a hot climate, refrigerators with effective thermal insulation are better suited. Some medicines can be stored in conventional freezers, so buying a refrigerator with a special camera should be justified, not in all cases its use is justified.
