Now have collected some refrigerator storage food issues, and which foods should not be placed in the refrigerator?

【 Fruits 】

Banana

If the bananas in 12 degrees centigrade of local storage, will make black rot of banana.

Fresh lychee

If the Lychee 0 ℃ environment places a day that will make their skin black, pulp turned sour.

Tropical fruit with the fear of low temperatures, is not suitable in the fridge, if refrigerated, it will "frostbite" fruit, so that it appears the epidermal SAG, dark brown spots, not only loss nutrition, but also easy metamorphic.

The immature fruits, it cannot be put into the refrigerator, it will be difficult to properly mature. The correct approach is to avoid light, cool and ventilate during storage.

【 Vegetables 】

Tomatoes

Tomatoes after freezing, the meat quality is vesicular, seem soft rot, or spallation phenomenon, there are dark spots on the surface, the Cook not cooked, fresh, serious then decay.

Cucumber green pepper

Cucumbers, green peppers stored in the refrigerator for a long time, the frozen "wound" – black, soft, turned sour.

President of hair sticking cucumber also. Because the temperature in the fridge for 4 ℃-General 6 ℃, and cucumber storage temperature is 10 ° c to 12 ° c, the green pepper is 7 ° c to 8 ° c and it would not be appropriate for a long time.

Leaf vegetables

Because it is easier to rotten cold storage. It is best not to put next to the refrigerator.

Chinese cabbage, celery, onion, carrot, suitable temperature: 0 ℃.

Cucumbers, eggplant, tomatoes and other suitable temperature:-10 ℃ 7.2 ℃.

Pumpkin appropriate at 10 ° c above.

【 Snacks class 】

Chocolate

Put the chocolate in the fridge out prone to surface after the Frost, not only lose the original mellow taste, but also conducive to the reproduction of bacteria.

Rui Li said that storing chocolate is the best temperature 5 ° c-18 ° c. Summer room temperature is too high, you can use plastic bags, sealed, and then placed in the refrigerator storage room for storage. Check out, don't immediately open and let it slowly at room temperature to be edible.

【 Food class 】

Ham

If the ham in the fridge cold storage, the water will freeze, fat precipitation, ham-caking or loose, meat quality, extremely easy to corruption.

Bread

Bread baking process, the flour of starch in the noncyclic Division is aging, and this is the bread and produce flexible and soft structure.

With the extension of the time, bread of amylopectin amylose portion slowly associating the soft bread becomes hard, this phenomenon is called "ripen." "Ripen" speed and temperature. In temperature (freezing point above) aging more rapidly, and the bread on the refrigerator, the hardened degree more quickly.

Fish should not be placed too long

Refrigerators should not be kept in fish for too long, cold temperature of household refrigerators to-15 ° c in General, the best refrigerators can only reach the-20 ° c, and fishery products, especially fish, the storage temperature is not up to-30 ° c below fish tissue occurs dehydration or other changes, such as frozen carp, long, prone to rancid fish, meat quality changes, inedible.

Therefore, the refrigerator storage of fish, time should not be too long.

【 Other 】

Traditional Chinese medicine

No place in a fridge, medicinal materials put into the refrigerator, and other food mix over time, not only various bacterial invasion of herbs, easily and easily gets wet, damaged the medicinal materials with pictures, so on a number of valuable medicinal materials, such as ginseng, ginseng and antler, tianma, etc., to be stored for a long time, can be placed in a clean glass bottle and then into moderation simmer the glutinous rice stir-fry yellowish tone, firm and dry cool place, the CAP sealing, shelve in cool and ventilated place.

Leftover cakes

Moon is made of flour, oil, sugar and nuts, and other ingredients, and after baking the refining of pastry.

Baking is not placed in the freezer storage. Although for some species of moon cake, put into the refrigerator can extend its shelf life time, but still affects its flavor. This is because the starch in the raw materials of moon cake in ripening after baking and become soft, but in low temperature conditions, aging of the starch will precipitate the aging water, becomes (that is "back to health"), the Moon become hard, taste worse.

Storage and frozen food, there are six major taboo:

1, hot food should never be put into operation in the refrigerator.

2. storage of food should not be too full, too tight, gaps, to the cold air convection, reduce unit load for long life, saving power.

3. mixed raw and cooked food is put together in order to maintain health.

According to food storage time, temperature requirements, the rational use of space inside, do not put the food is placed directly in the evaporator surface, to put it in jars, so as not to freeze in the evaporator, the inconvenience.

4, fish, meat and other foods can not handle it on the fridge.

Fresh fish, meat packing with plastic bags, storage in the refrigerator. Vegetables and fruits to the outer surface of the water to dry, put into a box at the bottom to zero temperature during storage.

5, not bottled liquid drinks into the refrigeration room to avoid Frost crack bottles.
