Which foods should be stored in ice?

Let me talk about the unsuitable ones, except for the unsuitable ones, you can put them...

Banana: If stored in an environment below 12℃, it will turn black and rot.

Fresh lychees: If left in an environment below 0 degrees for a day, the skin will turn black and the pulp will change flavor.

Cucumber: If placed in a refrigerator at 0°C for three days, the skin will become water-soaked and lose its flavor.

Tomatoes: After freezing, part or all of the fruit will become water-soaked and soft, showing round brown spots.

Bread: During the baking process of bread, the amylose portion of the starch in the flour has aged, which is why the bread has an elastic and soft structure. As the storage time increases, the linear part of the amylopectin in the bread slowly associates, making the soft bread gradually harden. This phenomenon is called "staleness". The speed of "aging" is related to temperature. It ages faster at low temperatures (above the freezing point), and bread hardens faster when placed in the refrigerator.

Cucumbers and green peppers: If cucumbers and green peppers are stored in the refrigerator for a long time, they will suffer from frostbite - turning black, soft, and stale. Cucumbers also grow sticky hair. Because the storage temperature in the refrigerator is generally around 4°C to 6°C, the suitable storage temperature for cucumbers is 10°C to 12°C, and the storage temperature for green peppers is 7°C to 8°C. Therefore, it should not be stored for a long time.

Ham: If stored in the refrigerator, the water in it will easily freeze, thus promoting the oxidation of fat in the ham, the quality of the ham will significantly decrease, and the retention period will be greatly shortened. ?

Chocolate: In summer, the indoor temperature is generally around 25°C. If you take the chocolate out of the refrigerator at this time, frost will form on the surface of the chocolate immediately. Over time, the chocolate will become damp and moldy. Change or get bugs.

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

Everyone likes to put food in the refrigerator to keep it fresh. Not all foods can be put in the refrigerator, especially the following common foods.

After tomatoes are frozen at low temperatures, their flesh becomes blister-like, soft and rotten, or spalled. There are black spots on the surface, and they are undercooked and have no umami flavor. In severe cases, they will rot.

If bananas are stored in a place below 12℃, they will turn black and rot.

If fresh lychees are left in an environment of 0℃ for a day, the skin will turn black and the pulp will change flavor.

After chocolate is refrigerated in the refrigerator, once it is taken out, a layer of white frost will form on the surface at room temperature, and it is easy to become moldy and deteriorate, losing its original flavor.

If ham is stored in the refrigerator at low temperature, the water in it will freeze, the fat will precipitate, the ham meat will become lumpy or loose, the meat will change flavor, and it will easily go rancid.

Bread: During the baking process of bread, the amylose portion of the starch in the flour has aged, which is why the bread has an elastic and soft structure. As the storage time increases, the linear part of the amylopectin in the bread slowly associates, making the soft bread gradually harden. This phenomenon is called "staleness". The speed of "aging" is related to temperature. It ages faster at low temperatures (above the freezing point), and bread hardens faster when placed in the refrigerator.

Cucumbers and green peppers: If cucumbers and green peppers are stored in the refrigerator for a long time, they will suffer from frostbite - turning black, soft, and stale. Cucumbers also grow sticky hair. Because the storage temperature in the refrigerator is generally around 4°C to 6°C, the suitable storage temperature for cucumbers is 10°C to 12°C, and the storage temperature for green peppers is 7°C to 8°C. Therefore, it should not be stored for a long time.

Leaf vegetables, because they rot more easily after being refrigerated.

Fresh juice will easily destroy its vitamins and other nutrients after freezing!

Stinky tofu can be stored in the refrigerator.

What foods should not be stored in the refrigerator

1. Bread should not be stored in the refrigerator

During the baking process of bread, the amylose amylose portion of the flour has been Aging, which is what gives bread its elastic and soft structure. As the storage time increases, the linear parts of the amylopectin branch in the bread slowly associate, making the soft bread gradually harden. This phenomenon is called "staleness".

The speed of "aging" is related to temperature. It ages faster at low temperatures (above the freezing point), and bread hardens faster when placed in the refrigerator.

2. Cucumbers and green peppers should not be stored in the refrigerator for a long time.

If cucumbers and green peppers are stored in the refrigerator for a long time, they will suffer from frostbite - they will turn black, become soft, and change their flavor. Cucumbers also grow sticky hair. Because the storage temperature in the refrigerator is generally about 4°C to 6°C, the suitable storage temperature for cucumbers is 10°C to 12°C, and the storage temperature for green peppers is 7°C to 8°C. Therefore, it should not be stored for a long time.

3. Bananas

Storing bananas at temperatures below 12°C will cause them to turn black and rot.

4. Tomatoes

After being frozen at low temperature, the meat of tomatoes will appear blister-like, soft and rotten, or may fall apart, with black spots on the surface, undercooking, and no umami flavor. , in severe cases it becomes rancid and rotten.

5. Ham

If the ham is stored in the refrigerator at low temperature, the water in it will freeze, the fat will precipitate, the leg meat will become lumpy or loose, the meat will change flavor, and it will be easily spoiled. .

6. Chocolate

After chocolate is stored in the refrigerator, once it is taken out, a layer of white frost will form on the surface at room temperature. Original flavor.

7. Fresh lychees

If fresh lychees are left in an environment of 0℃ for one day, the skin will turn black and the pulp will change flavor.

8. List of how long food can be stored in the refrigerator

9. Six taboos when using refrigerators

a. Hot food must not be placed in a running refrigerator.

b. Food should not be stored too full or too tightly. There should be gaps to facilitate cold air convection, reduce the load on the unit, extend the service life, and save electricity.

c. Do not mix raw and cooked food together to maintain hygiene. According to food storage time and temperature requirements, make reasonable use of the space in the box. Do not place food directly on the surface of the evaporator, but place it in a container to avoid freezing on the evaporator and making it inconvenient to take out.

d. Fresh fish, meat and other foods cannot be placed in the refrigerator without processing. Fresh fish and meat should be packaged in plastic bags and stored in the freezer. The outer surface of vegetables and fruits should be wiped dry, placed at the bottom of the box, and stored at above zero temperatures.

e. Do not put bottled liquid drinks into the freezer to avoid freezing and cracking the bottles. It should be placed in a refrigerator or on a door stop, and it is best to store at a temperature of about 4°C.

f. Refrigerators that store food should not also store chemicals.

In addition:

A. Cucumbers and tomatoes: Cucumbers are resistant to ethylene, and tomatoes contain ethylene. Putting the two together will cause cucumbers to deteriorate and rot.

B. Bread and biscuits: Biscuits are dry and have no moisture, while bread has more moisture. When the two are put together, the biscuits will become soft and lose their crispness, and the bread will become hard and unpalatable.

C. Rice and fruits: Rice is prone to heat. Fruits will easily evaporate water and dry up when heated. Rice will also absorb moisture and become moldy or infested with insects.

D. Fresh eggs, ginger, and onions: There are many small pores on the eggshell. The strong smell of ginger and onions will penetrate into the pores and accelerate the deterioration of fresh eggs. Over time, the eggs will deteriorate. Smelly.
