Some difficult foods should not be placed in the refrigerator, and which foods should not be put in

Bananas: When stored in an environment below 12, it will make it black and rotten.

Cucumber: If left in the refrigerator for three days, the skin will become water-soaked and lose the flavor it holds.

Tomatoes: When frozen, some or all of the fruit will be soaked in water and soft and rot, showing brown round spots.

Bread: During the baking process of bread, the starch linear parts in the flour have aged, which is why the bread develops an elastic and soft structure. As the bread is left for a longer period of time, the amylopectin in the bread slowly associates, and the soft bread gradually hardens, a phenomenon called "aging".

The rate at which "aging" is temperature dependent. It ages faster at low temperatures (above the freezing point), while bread hardens faster when it is stored in the refrigerator.

Cucumber and green peppers: Cucumbers and green peppers that have been stored in the refrigerator for a long time will cause frostbite "injury" - blackening, softness, and taste. Cucumbers also grow sticky hair.

Because the temperature stored in the refrigerator is generally about 4 to 6, while the suitable storage temperature for cucumbers is 10 to 12, and green peppers are 7 to 8. Therefore, it is not suitable to exist for a long time.

Ham: If stored in the refrigerator, the moisture in it is easy to freeze, which promotes the oxidation of the fat in the ham, and the quality of the ham will be significantly reduced, so that the shelf life is greatly shortened. �

Chocolate: In summer, the indoor temperature is generally around 25, at this time, if the chocolate is taken out of the refrigerator, the surface of the chocolate will immediately frost, and after a long time, the chocolate will become mildew or insects due to moisture.

Leafy vegetables: It is best not to put them next to the refrigerator, otherwise they will rot.

Fresh vegetables should not be put in the refrigerator, if you put them, the vegetables are not as fresh as outside!

<> "Food that should not be put in the refrigerator Potatoes."

1. Fruits:

Bananas, lychees, unripe fruits.

2. Vegetables:

Tomatoes, Chinese cabbage, celery, potatoes, cucumbers, onions, pumpkin, green peppers, carrots.

3. Food:

Ham, candy, preserved fruits, bread, honey, tea, fish, pickles, milk powder, biscuits, yellow sauce, and coffee.

Biscuits, candies, honey, pickles, yellow sauce, preserved fruits, powdered foods, dried foods, etc., do not need to be put in the refrigerator. They either have very low water content and microorganisms cannot multiply; Or the concentration of sugar and salt is too high, the osmotic pressure is very high, there is very little free water, and microorganisms cannot multiply. Putting it in the fridge is a waste of electricity and takes up space.

Putting honey in the refrigerator will cause it to crystallize and precipitate glucose. This change does not affect the safety of honey, nor does it affect its nutritional value, but it only affects the uniformity of the taste. Dry products such as tea, milk powder, and coffee are put into the refrigerator, if they are not tightly sealed, the taste and moisture in the refrigerator will enter the food, which will not only affect the flavor, but also be easy to mold.

Some fruits and some fruits cannot be put in the refrigerator, such as mangoes, bananas and other tropical fruits, which are suitable for storage around 12, usually placed in a cool place at room temperature. If you put them in the refrigerator, they will be damaged by the cold air and spoil in advance. Starchy foods such as steamed buns, flower rolls, and bread, if you can't finish one or two meals, you can put them at room temperature.

Keeping them in the refrigerator will actually speed up the drying and hardening of these foods. If you want to store it for more than 3 days, it is best to wrap it and put it in the freezer, and take it out and microwave it to thaw it for 1 2 minutes when eating, and the taste is as fresh as ever.

Bananas and lychees in the refrigerator will accelerate spoilage, bread and cakes in the refrigerator will accelerate drying, and chocolate in the refrigerator for a long time will also cause a bad taste.

It is best not to put these few foods in the refrigerator, and learn early to benefit.

The refrigerator is to reduce the speed of various chemical reactions in food through an artificial low-temperature environment, which is conducive to preserving the quality of food. In ordinary life, frequent opening and closing of the refrigerator door can cause the temperature in the refrigerator to rise, and bacteria in the food will grow, and the refrigerator will also produce a kind of germs ———psychrophiles" that contaminate the food. This fungus can grow in a 0 4 environment, hide in a variety of foods such as meat products, dairy products, vegetables, seafood, etc., and multiply fastest at 4 6 hours, which is the temperature of the refrigerator room.

Therefore, the refrigerator should be cleaned and disinfected regularly, especially in summer.

It's important to note that not all food is suitable for fridge storage. Some foods are in the refrigerator, which will shorten the shelf life; Some foods can be stored for a long time without being kept in the refrigerator, such as biscuits, candies, honey, pickles, yellow sauce, preserved fruits, powdered foods, dried foods, etc. They either have very low water content and microorganisms cannot multiply; Or the concentration of sugar and salt is too high, there is very little free water, and microorganisms cannot multiply.

At the same time, tropical fruits such as mangoes and bananas are suitable for storage at about 12 years old, and they can be stored in a cool place at room temperature. If you put them in the refrigerator, they will be damaged by freezing and deteriorate prematurely.

I know bananas, chocolates, fresh lychees, tomatoes.

tropical fruits such as tomatoes and bananas;

Foods that are not perishable and do not need to be kept fresh.
