What is the safe storage temperature of different foods?

Food tastes very different at different temperatures. Every food has a relatively safe "body temperature". At this temperature, the shelf life of food is long, while maintaining the best nutrition and taste.

1, quick-frozen food (shelf life is about -20℃)

The quality of quick-frozen food is stable between -25℃ and-65438 08℃. If it is higher than this temperature, the shelf life will be shortened and the taste will change accordingly. If the refrigerator at home can't reach-18℃, it's best to open the frozen food and eat it as soon as possible, otherwise it will go bad easily.

2. Fresh fish (not easy to deteriorate at -3℃)

At this temperature, fish is not easy to go bad and its flavor can be guaranteed, but it should be eaten as soon as possible and not stored in the refrigerator for too long.

3. Meat (-18℃ is the most suitable)

Pork and beef should be frozen at-18℃, which can maintain the integrity of cell wall and is beneficial to the maintenance of water. If the meat is refrigerated at -2℃~5℃, it can be stored for up to one week.

4, vegetables (not less than 0℃)

The suitable storage temperature of Chinese cabbage, celery, onion and carrot is about 0℃. The best temperature for storing potatoes is 2℃ ~ 4℃, and potatoes will germinate if the temperature is too high. The suitable storage temperature of cucumber, eggplant and tomato is between 7.2 ~ 10℃. Pumpkin is suitable for storage above 10℃; The optimum storage temperature of sweet potato (sweet potato) is above 65438 05℃. If the temperature is low, it will become stiff and you can't eat it.

5, dishes (cold dishes 4℃, hot dishes 60℃)

When the temperature of cold dishes is below 4℃, it can present the best flavor; Hot dishes need to be kept at around 60℃. You can put the plate in the refrigerator for 3 minutes before cold dishes, or put the plate in the oven for 4 minutes before hot dishes, so that the dishes taste best. Hotel chefs usually do this.

6, fruit (different types, different temperatures)

The optimum storage temperature of bananas is about 65438 03℃. Orange 4℃ ~ 5℃; Apple is-1℃ ~ 4℃; Mango is10℃ ~13℃; Papaya 7℃; Litchi is 7℃ ~ 10℃, so litchi is not suitable for storage in refrigerator.

7. Fruit juice (8℃ ~ 10℃ is the most nutritious)

All kinds of fruit juices should be drunk at around 8℃ ~ 10℃. Once opened, the juice begins to lose its nutrition, so don't store it in the refrigerator for too long. The nutrition of aseptic juice made of citrus, grapefruit and pineapple can be preserved for 7 ~ 10 days.

8. Ice cream (-13℃ ~- 15℃) tastes good.

-13℃ ~- 15℃ ice cream tastes the most enjoyable. At this temperature, putting ice cream into your mouth will have the best taste and will not strongly stimulate your stomach.

9, soda (4℃ ~ 5℃ is the most thirst-quenching)

The best drinking temperature of soft drinks is 4℃ ~ 5℃. Soft drinks at this temperature are the most thirst-quenching and will not cause irritation to the stomach.

10, watermelon (the best taste is around 8℃)

The taste is purest at around 8℃. Many people are used to cutting watermelons and eating them in cold storage. In fact, after a long period of cold storage, a film will form on the surface of watermelon pulp, thus losing its taste, and the water in it is also easy to form ice crystals, which will irritate the throat or cause adverse reactions such as toothache after eating.

1 1, honey (with warm water)

Washing honey with warm water at 50℃ ~ 60℃ can retain the nutrition in honey to the greatest extent. Overheated boiling water not only changes the sweetness of honey and makes it sour, but also denatures enzymes in honey, produces excessive hydroxymethylaldehyde and destroys nutrients.
