What is the best temperature for food refrigeration and freshness?

The refrigerator is the best tool for food preservation, and the temperature required for different foods is different, so the temperature of the refrigerator should be set according to the type of food stored. For example, green leafy vegetables 12 degrees, tropical fruits 10 degrees, cooked food 8 degrees, beer drinks 4 degrees, fresh meat 18 degrees, fish and shrimp 0 degrees, etc., in principle, have nothing to do with the season. When the temperature exceeds 30 degrees in summer, the design ability of the refrigerator is exceeded, and the set temperature should be adjusted a little higher to avoid serious freezing in the refrigerator due to the non-stop of the compressor, which is a dedication function to ensure the normal use of the refrigerator.

The refrigeration and preservation time of food should be controlled within a week, and the temperature should be controlled between zero and four degrees.

However, it is better not to buy too much food and store it for too long to avoid spoilage, which is not only bad for health, but also causes waste.

Hello, the temperature of food refrigeration is generally 5 10 degrees, but most of our household refrigerators are below 10 degrees, thank you.

**Uh, the general temperature of refrigeration and preservation is relatively close to 0 degrees, because it belongs to preservation rather than freezing, so it is generally about minus 2 degrees, if it is too low, it has been frozen, this depends on the length of your storage time, if the storage time is short, it can be around 0 degrees, and the temperature is slightly lower if the time is long. As long as it doesn't freeze.

Food refrigeration and preservation, it is best to keep it at about 5 degrees is the best, such a thermometer can ensure the freshness of the food, but also prevent the oxidation of the food, and can be taken out at any time to cook, can ensure its taste.

If the temperature is too low, some vegetables and fruits may freeze, and if the temperature is too high, the fruits will not be fresh.

The quality of quick-frozen food (around -20 has a long shelf life) The quality of quick-frozen food will be relatively stable between -25 and -18, and if it is higher than this temperature, the shelf life will be shortened accordingly, and the taste will also change. If the refrigerator at home does not reach -18, it is best to eat the quick-frozen food as soon as possible after opening, otherwise it is easy to spoil. 2. Fresh fish (-3 not easy to spoil) At this temperature, the fish is not easy to spoil, which can ensure its umami, but it should be eaten as soon as possible and should not be stored in the refrigerator for too long.

3. Meat (-18 is the most suitable) pork and beef should be frozen and stored in the environment of -18, which can maintain the integrity of the cell wall and is conducive to the retention of moisture. If refrigerated in -2 5 conditions, meat can last for up to a week. 4. The suitable storage temperature of vegetables (not lower than 0) cabbage, celery, onions, carrots, etc. is about 0; The best temperature for storing potatoes is 2 4, too high the temperature will sprout potatoes; Cucumbers, eggplants, tomatoes, etc., should be stored at a temperature of between; Pumpkin should be stored above 10; The best temperature for storing sweet potatoes (sweet potatoes) is 15 or more, and if the temperature is low, it will be stiff and inedible.

5. Dishes (4 cold dishes, 60 hot dishes) When the temperature of cold dishes is below 4, the best flavor can be presented; Hot dishes need to be kept at around 60. You can put the plate in the refrigerator for 3 minutes before serving cold dishes, or put the plate in the oven for 4 minutes before serving hot dishes, so that the dishes taste best. Hotel chefs generally do just that.

6. Fruits (different types, different temperatures) bananas are stored at about 13 is the most suitable; oranges are 4 5; Apples are -1 4 ; 10 13 for mango; papaya is 7; Lychee is 7 10, so lychee is not suitable for storage in the refrigerator.

1. The temperature of the refrigerator compartment of the general refrigerator can be kept at about 5-8 degrees, and the temperature of the freezer room is better at minus 18 degrees Celsius.

2. Because there will be temperature adjustment buttons 1-7 gears in the refrigerator compartment of the general refrigerator, the button can be adjusted to 2-3 gears in summer, and it can be adjusted to 6-7 gears in winter.

3. Mainly because the external temperature will affect the performance of the refrigerator, so that the differential shift makes the refrigerator have a good integration of the inside and outside. So it is appropriate to keep it around 5-8 degrees. The freezer temperature is related to the quality of the refrigerator itself and external factors.

Because the refrigerator is not prone to freezing and frosting, it can also maximize its energy efficiency.

4. The freezer compartment of the refrigerator plays a role in freezing, 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.

The refrigerator freezer is generally at a temperature of 2-8 degrees Celsius and is used to store fruits and vegetables. Keep the temperature of the food close to 0 degrees but not lower than 0 degrees, and maintain a certain temperature in the space, so that the food will last longer and the freshness will be better.

Vegetables: Green vegetables should be stored under the condition of no less than 0, otherwise the chlorophyll will be destroyed by freezing; Cucumbers, eggplants, and tomatoes should be stored at a suitable temperature of 7 10 If the temperature is too low, the taste will deteriorate, and it will rot after a long time; The most suitable storage temperature for potatoes is 2-4, higher than 4 easy to germinate; The pumpkin is about 10, and the sweet potato is more than 15, and the temperature is too low to cause coreing, so sweet potatoes should not be placed in the refrigerator.

Fruits: Fruits should only be refrigerated, not frozen. Apple 7 12 days; citrus 7 days; pears 1 to 2 days; tomato 12 days; Tropical fruits such as bananas, star fruit, lychee, longan, rambutan, guava, mangosteen, and dragon fruit should not be put in the refrigerator, otherwise they will get frostbitten.

Fruits such as strawberries, bayberry, and mulberries are best bought and eaten immediately, but if they are put in the refrigerator, they will not only affect the taste, but also be prone to mildew.

Dishes: Refrigerated leftovers are best left out overnight and reheated before eating for safety. Dishes that have not been "touched with chopsticks" can be left for 2 to 3 days.

Do not cook fish and meat for more than 3 days. It is important to note that dishes should be thrown away as soon as they have an abnormal condition such as an off-smell or a slippery surface.

Fresh fish: The best storage temperature for fresh fish is below -30, and the fish will not spoil easily within a year when stored at this temperature. However, the minimum temperature of the household refrigerator is -15 -20, and the meat quality of the fish will slowly change such as dehydration and decomposition, and it can generally only be shelved for about half a year.

If fresh fish can only be stored in the refrigerator for one day, pay attention to the fact that fresh shellfish such as clams and oysters should be placed in the refrigerator and should not be frozen to avoid freezing to death.

Meat: If you need to preserve chicken and duck meat for a longer period of time, it must be frozen. If refrigerated, it can only be stored for a maximum of 3 days.

If ham and bacon are placed in the freezer, the shelf life will be shortened, because the moisture in the ham forms fine ice particles at low temperatures, which accelerates the oxidation of the fat in the ham. Low temperatures also cause fat to precipitate out of ham and bacon, causing the meat to clump or loosen, affecting quality and flavor. Therefore, ham and bacon are best stored in a ventilated and cool place.

The temperature of food refrigeration and preservation is generally between 2 and 8, which can be fine-tuned according to the different ingredients.

In addition, the temperature of the upper layer of the refrigerator is low and the temperature of the lower layer is high, so you can choose the location where the ingredients are stored according to your needs.

It is better to refrigerate cooked food between 1 and 5 degrees, raw meat should be refrigerated at 1 to 2 degrees, cold-resistant vegetables should be refrigerated at 0 degrees to 1 degree above zero, and general vegetables are refrigerated at 5 to 15 degrees.

Food refrigeration and preservation should be based on winter and summer. Summer is best. 2 to 4 degrees. Room temperature is fine in winter, because the weather is cold in winter.

Different food freshness temperature requirements are different:

The best refrigeration temperature for fresh fish is minus 3 degrees Celsius.

Meat is refrigerated between 2 and 5 degrees Celsius and can be stored for up to a week.

Cask and bottled beer should be kept at 0 to 5 degrees, while bottled cooked beer should be kept at 10 to 25 degrees.

The best temperature for refrigeration of fresh milk is 2 degrees to 4 degrees.

Storing tea leaves at temperatures of minus 20 to 10 degrees Celsius can prevent deterioration of quality for a long time and keep vitamins from being damaged.

The optimal temperature for storing alcohol is between 5 degrees and 20 degrees.

The best temperature for grain storage: 8 degrees -15 degrees, which can prevent insects in the grain.

The best temperature for frozen fish: it is below minus 3 degrees, at this temperature the fish is not easy to spoil, and its umami can be preserved.

The best temperature to store eggs: below 15 degrees, eggs are not easy to spoil.

The best temperature for storing potatoes: 2-4 degrees, too high a temperature will germinate, and affect eating.

The taste of food varies greatly depending on the temperature. Each food has a relatively safe "body temperature" at which it can be shelf-lived for a long time while maintaining optimal nutrition and taste.

What is the best temperature for food refrigeration and preservation, depending on the type of food, the temperature required for different foods is different, and the best refrigeration temperature for fresh fish is minus 3 degrees; Meat is refrigerated between 2 and 5 degrees Celsius and can be stored for up to a week. Cask and bottled beer should be kept at 0 to 5 degrees, while bottled cooked beer should be kept at 10 to 25 degrees. The best temperature for refrigeration of fresh milk is 2 degrees to 4 degrees. Storing tea leaves at temperatures of minus 20 to 10 degrees Celsius can prevent deterioration of quality for a long time and keep vitamins from being damaged. The optimal temperature for storing alcohol is between 5 degrees and 20 degrees. The best temperature for grain storage: 8 degrees -15 degrees, which can prevent insects in the grain. The best temperature for frozen fish: it is below minus 3 degrees, at this temperature the fish is not easy to spoil, and its umami can be preserved.

Eggs: The best temperature for storage is below 15, and eggs are not easy to spoil. Fresh milk:

The optimal temperature for refrigeration is 2 4 . Fresh fish: The optimal refrigeration temperature is -3.

Frozen fish: The best temperature for storage is also below -3, at which the fish are not easy to spoil. Tea:

Storing tea leaves at a temperature of -20 to 10 can prevent quality deterioration for a long time and keep the vitamins from being damaged. Meat: the optimal temperature is 2 5 , under which conditions can be kept refrigerated for a week.

Potatoes: The best temperature for storing potatoes is 2 4, too high a temperature will sprout. Sweet Potato:

Optimum temperature 15

It is most suitable around 0-4 degrees. Because at this temperature the water does not freeze and maintains maximum density.

Case 5-15 degrees is the most suitable. The temperature range of the freezer compartment of the refrigerator is generally 4-24 degrees (18 degrees for three-star and 24 degrees for four-star stars), and the temperature range of the refrigerator is 5-15 degrees. When the mechanical thermostat is adjusted, the freezer and refrigerator temperatures change at the same time.

5-15 degrees is most suitable.

1. The temperature range of the refrigerator freezer is generally 4-24 degrees (18 degrees for three-star and 24 degrees for four-star), and the temperature range of the refrigerator is 5-15 degrees. When the mechanical thermostat is adjusted, the freezer and refrigerator temperatures change at the same time.

2. The refrigerator is a tool to provide food preservation, and the freshness temperature required for different foods is different, so the temperature of the refrigerator should be set according to the type of food stored. For example, green leafy vegetables 12 degrees, tropical fruits 10 degrees, cooked food 8 degrees, beer drinks 4 degrees, fresh meat 18 degrees, fish and shrimp 0 degrees, etc., in principle, there is no relationship with the season.

3. When the ambient temperature is higher than 30 degrees in summer, the set temperature should be adjusted higher to prevent the compressor from not stopping, resulting in serious freezing in the refrigerator, which is to sacrifice the function of the refrigerator to ensure the normal use of the refrigerator.

What is the best temperature for food refrigeration and freshness? The temperature of 5 7 degrees Celsius is the most suitable for food refrigeration and preservation, which can not only ensure the freshness of the food, but also ensure that the moisture is sufficient, and also ensure that the nutrients are not lost, which is the best temperature for cold preservation of food. However, refrigerated food should not be stored for too long, and it is best to eat as much as you want.

It is best to refrigerate and keep the temperature to about 10 degrees, and it can also play a special role in preservation.

The storage temperature is about 4 degrees Celsius. That is, the temperature range of the refrigerator cold room should be about 1 to 5 degrees. It will be adjusted according to winter and summer. This temperature is the best for keeping vegetables and other ingredients fresh.

The preservation of the refrigerator is generally about 4 to 5 degrees, when adjusting the refrigerator gear, it can be operated according to the seasonal changes, the refrigerator preservation usually has 0-7 gears, adjusted to 3 gears in summer, can be adjusted in 4 gears in spring and autumn, and adjusted to 5 gears in winter, these are more reasonable refrigerator temperature adjustment methods.

It is also necessary to pay attention to the adjustment of the thermostat in the refrigerator, for example, the temperature itself is relatively high in summer, and the temperature grade should be adjusted lower. The higher the number, the lower the temperature. The thermostat is between 1st and 3rd gear.

In winter, the temperature decreases, in order to achieve better preservation, you can adjust the number higher, such as to 4 or 5 gear.

What is the best temperature for food refrigeration and freshness? Food is refrigerated and preserved. It is usually between 2 and 6 degrees Celsius.

In this way, the food can be kept fresh. Not all foods are at this level. Some of them he had to see the instructions above.

Generally speaking. A lot of food is 2 to 6 degrees Celsius, the temperature is too low. It will freeze into ice.

If you open high, you won't keep it fresh.
