What is the best temperature for food refrigeration?

If it is just ordinary food refrigeration, the refrigerator of the general household refrigerator can meet the daily food refrigeration at a temperature of about 0 minus 15 degrees, and if there is too much food, the temperature can be lowered to minus 18 degrees.

Generally, it is best to control it at about 4 to 24, which can have the effect of refrigeration and freshness.

Generally, it is best to store food for about a week at about 15 degrees, and it will not be bad, and the freshness is very good.

Under normal circumstances, the temperature of the freezer should be set to minus 18 degrees, if there is less food, there is no need to freeze and keep fresh for a long time, in the case of ensuring that the food is frozen and fresh, the temperature setting can be adjusted higher, that is, the temperature of the freezer is set to minus 12 16 degrees, which is more energy-saving.

According to the stored food, the temperature of the refrigerated room in the box is appropriately selected, such as the refrigeration temperature of fresh meat and fresh fish is about -1, the refrigeration temperature of eggs and milk is about 3, and the refrigeration temperature of vegetables and fruits is about 5.

It should be noted that the number marked on the knob disc of the refrigerator thermostat does not refer to the specific temperature value in the refrigerator, but only indicates the degree of low temperature, and the larger the general indication number, the lower the temperature in the refrigerator. According to the temperature needs of the stored food and the ambient temperature, the rotating disk of the thermostat can be rotated to adjust the temperature in the refrigerator to meet the requirements.

Related Notes:

Food refrigeration is a storage method that maintains the quality of food at refrigeration temperature (above freezing) after it has been cooled. There are two methods of refrigeration: air refrigeration and modified atmosphere refrigeration.

Air refrigeration method: The process effect of food air refrigeration mainly depends on the storage temperature, air humidity and air flow rate. Storage temperature is the most important factor in the refrigeration process, which refers not only to the temperature of the air in the cold storage, but more importantly to the temperature of the food.

The relative humidity of the air has a direct impact on the shelf life of the food, too high will lead to condensation on the surface of the food, too low will lead to the evaporation of water in the food and wilting.

The principle of determining the air flow rate is to take away the heat generated by the food (biochemical reaction heat or respiratory heat, etc.) and the heat infiltrated by the outside world in time, and ensure that the indoor temperature is evenly distributed. Modified atmosphere refrigeration (CA storage method) refers to the method of using gas to adjust the environment to extend the storage and shelf life of food on the basis of refrigeration.

The principle is: in a certain closed system, the regulatory gas (high carbon dioxide, low oxygen) different from the normal atmospheric composition is obtained through various adjustment methods, so as to inhibit the physiological and biochemical process of food deterioration caused by the food itself or the microbial activity process acting on the food. At present, the technologies used mainly include the refrigeration method of controlled atmosphere storage, the film closed gas regulation method and the vacuum storage method.

Summary. What is the temperature range of food freezing -18 -1, quick-frozen food (about -20 has a long shelf life) The quality of quick-frozen food will be relatively stable between -25 and -18. Food freezing refers to the process of freezing the liquid water in fish, meat and other foods into a solid state by means of low temperature.

It is a safe and healthy way to store it, which can effectively inhibit the growth and reproduction of microorganisms in food, prevent food from spoiling, and at the same time, it is easy to restore to its original state. However, the freezing method is not suitable for eggs, lettuce, canned food, and some sauce products, etc. At the same time, it should be noted that not all harmful microorganisms will die during the freezing process, and it is possible that they are sub-dead.

Hello, what is the best temperature for frozen food and seafood.

What is the temperature range of food freezing -18 -1, quick-frozen food (about -20 has a long shelf life) The quality of quick-frozen food digging chain belt will be relatively stable between -25 and 18. Food freezing refers to the process of freezing the liquid water in fish, meat and other foods into a solid state by means of low temperature. It is a safe and healthy way to store it, which can effectively inhibit the growth and reproduction of microorganisms in food, prevent food from spoiling, and at the same time, it is easy to restore to its original state.

However, the freezing method is not suitable for eggs, lettuce, canned food and some sauce products, etc. At the same time, it should be noted that not all harmful microorganisms will die during the freezing process, and it is possible that they are sub-dead.

1. The shelf life temperature of the conventional seafood stool is 0-10, which is used for short-term low-temperature refrigeration and turnover use; 2. Generally, the storage temperature of aquatic products and seafood in the freezer is -25 -35, which is used as long-term freezing; 3. The storage temperature of special types of seafood (tuna) is -60, which is also used as long-term freezing.

How many degrees below zero should I buy the freezer for cold chain food?

The temperature in the freezer compartment of the refrigerator is generally below -18 degrees. This sub-zero temperature is relatively fast when it is frozen, which is conducive to the freezing of fast food. The refrigerator freezer room plays a freezing role, the temperature is too low to freeze into ice, and the temperature is too high to play its role well, so the temperature of the freezer is kept at minus 18 degrees Celsius, so that the refrigerator is not easy to freeze and frost, and it can also maximize its energy efficiency.

What I want to ask is how many degrees below zero the freezer is bought, and whether the refrigeration effect of the freezer must be up and down.

The temperature of the freezer is generally about minus 18 degrees Celsius, which can be a good guarantee for the storage of food that needs to be frozen.

Summary. Different foods have different storage temperatures, choose the appropriate temperature according to the type of food, and the common storage temperatures are as follows:

1. The best refrigeration temperature of fresh fish is about -3 degrees Celsius, such as about -18 degrees Celsius, which can keep fresh fish for half a year.

2. Meat can be stored for one week when refrigerated at 2-5 degrees Celsius.

3. Barreled beer and bottled beer should be stored at 0-15 degrees Celsius, while bottled cooked beer should be stored at about 10-15 degrees Celsius.

4. The best temperature for refrigeration of fresh milk is 1-6 degrees Celsius, which can inhibit the reproduction of bacteria and prevent deterioration.

What is the temperature at which food is refrigerated?

Hello, I have seen your question and am sorting out the answer, please wait a while

The storage temperature of different foods is not the same, according to the type of food to choose the appropriate temperature, the common storage temperature is as follows: 1. The best refrigeration temperature of fresh fish is about -3 degrees Celsius, such as about -18 degrees Celsius, which can keep fresh fish for half a year. 2. Meat can be stored for one week when refrigerated at 2-5 degrees Celsius.

3. Barreled beer and bottled beer should be stored at 0-15 degrees Celsius, while bottled cooked beer should be stored at about 10-15 degrees Celsius. 4. The best temperature for fresh milk refrigeration is 1-6 degrees Celsius, which can inhibit the reproduction of bacteria and prevent deterioration.
