10 kinds of food can not be put into the refrigerator

When using the refrigerator, be sure to use common sense, not only to extend the life of the refrigerator, but also to eat fresh and healthy food. Now collect some questions that need attention when storing food in the refrigerator. Which foods can not be put into the refrigerator?

[Fruit]

Bananas: If bananas are stored below 12°C, the bananas will be black and rot.

Fresh Litchi : If Litchi is allowed to stand in a 0°C environment for a day, the skin will become black and the flesh will taste bad.

Tropical fruits: Due to the fear of low temperatures, it is not suitable for refrigerators. If it is refrigerated, it will “frost” the fruit, causing the skin to sag and dark brown spots, which will not only lose nutrition but also deteriorate. Unripe fruit, it can not put into the refrigerator, otherwise it will be difficult to mature normally. The correct method is to store light in a cool, ventilated place.

【Vegetables】

Tomato : After the tomato is frozen at low temperature, the meat is blister-like, which appears soft and rotten, or spalling phenomenon occurs, the surface has dark spots, boiled, no umami, and severe rot.

Cucumber and green pepper: cucumber, green pepper in the refrigerator for a long time, there will be frozen "injury" - black, soft, off taste. Cucumbers also grow long hair. Because the temperature stored in the refrigerator is generally about 4 °C to 6 °C, and the appropriate storage temperature of cucumber is 10 °C to 12 °C, green pepper is 7 °C to 8 °C, so it should not be stored for long. Suitable storage temperature for cucumbers, eggplants, tomatoes, etc. is between 7.2°C and 10°C

Leaf vegetables

Because it is easier to rot after refrigeration.

It is best not to put a refrigerator.

Cabbage, celery, onions, carrots and other suitable storage temperature is about 0 °C.

Pumpkin is suitable for storage above 10°C.

Snacks

Chocolate: After putting in the chocolate in the refrigerator, the surface is prone to white frost, not only losing the original mellow taste, but also conducive to the proliferation of bacteria. Li Li said that the best temperature for storing chocolate is 5°C-18°C. When the room temperature in summer is too high, it can be sealed with a plastic bag and then stored in a refrigerator freezer. When you take it out, don't open it immediately, let it slowly warm to room temperature before eating.

【Food category】

Ham: If the ham is stored in the refrigerator at low temperature, the moisture in the refrigerator will freeze, the fat will precipitate, and the ham will be agglomerated or loose. The meat will taste bad, and it will be easily corrupted.

Bread: In the baking process, the straight-chain starch fraction in the flour has aged, which is why the bread produces a flexible and soft structure. With the extension of the shelf life, the linear portion of the amylopectin in the bread slowly associates, and the soft bread gradually hardens. This phenomenon is called "changing." The speed of "changing" is related to temperature. At low temperatures (above the freezing point) the aging is faster, while in the bread freezer, the degree of hardening becomes faster.

Fish: can not put too long The fish in the refrigerator should not be stored too long, the refrigeration temperature of household refrigerators is generally -15 °C, the best refrigerator can only reach -20 °C, while aquatic products, especially fish, are stored If the temperature does not reach -30°C, dehydration or other changes will occur in the fish tissue. If the carp is refrigerated for a long time, it is prone to fish rancidity, meat quality changes, inedible. Therefore, the time for storing the fish in the refrigerator should not be too long.

【other】

Traditional Chinese medicine: Should not be placed in the refrigerator, herbs in the refrigerator, and other foods mixed for a long time, not only a variety of bacteria easily invade medicinal herbs, but also easy to damp, destroy the medicinal properties of herbs, so for some valuable herbs, such as Ginseng, pilose antler, gastrodia, codonopsis, etc. For long-term preservation, they can be placed in a clean glass bottle, and then put in the right amount of glutinous rice, stir-fry until dark yellow, put it in until it cools, put it tightly, put it aside. In a cool and ventilated place.

Moon cakes leftovers: Moon cakes are made from ingredients such as flour, oil, sugar and nuts, and are baked pastries. Baked foods should not be stored in the refrigerator. Although for some varieties of moon cakes, the refrigerator can extend the shelf life, but it will affect the flavor. This is because the starch in the raw materials of the moon cake is matured after being baked and becomes soft, and under the condition of low temperature, the matured starch will precipitate water and become aged (that is, “return to life”), causing the mooncake to change. Hard, bad taste.

There are six taboos for storing and freezing food:

Hot food can never be put into a running refrigerator.

Store food should not be too full, too tight, to leave gaps in order to facilitate the convection of cold air, reduce the unit load, extend the service life, save power.

Food must not be cooked and mixed together to maintain hygiene. According to food storage time, temperature requirements, rational use of space inside the box, do not put the food directly on the evaporator surface, to be placed in the container, so as not to freeze on the evaporator, inconvenient to remove.

Fresh fish, meat and other foods can not be put into the refrigerator without treatment. Fresh fish and meat are packed in plastic bags and stored in the freezer. Vegetables and fruits should be wiped dry on the outside surface, placed in the bottom of the box, to zero temperature storage is appropriate.

Do not put bottled liquid beverages in the freezer to avoid freezing the bottles. Should be placed in the refrigerator or door, with a temperature of about 4 °C is best stored.

Refrigerators that store foods should not store chemicals at the same time.
