We all know.
Storing food in the refrigerator can prolong the shelf life.
Do you know?
Some foods are not suitable for storage in refrigerators.
Let’s take a quick look ~
Starch foods such as steamed bread, flower rolls and bread cannot be put into the refrigerator, which will accelerate the drying and hardening speed. If they cannot be eaten for a short time, they can be sealed and put into the freezing chamber for freezing.
In addition, bread and biscuits should not be stored together, as a result, the moisture in the bread will be transferred to the biscuits, making the biscuits soft and the bread hard, which is not good for both.
The best temperature for storing chocolate is 5 ℃ ~ 18 ℃. After the chocolate put into the refrigerator is taken out, the surface is prone to white frost, which not only loses the original mellow taste, but also facilitates the reproduction of bacteria. The optimal temperature for storing chocolate is 5 ℃ ~ 18 ℃.
Fish in refrigerators should not be stored for too long. The freezing temperature of domestic refrigerators is generally – 15 ℃, and the best refrigerator can only reach – 20 ℃; However, aquatic products, especially fish, will undergo dehydration or other changes when the storage temperature does not reach below – 30 ℃. For example, crucian carp is prone to rancidity and changes in meat quality after long-term cold storage, which is inedible.
The medicinal materials should not be placed in the refrigerator. If the medicinal materials are placed in the refrigerator and mixed with other foods for a long time, not only are various bacteria easy to invade the medicinal materials, but also they are easy to be affected with damp, thus destroying the medicinal properties of the medicinal materials.
Tomatoes after low-temperature refrigeration, the meat is blister – like, soft and rotten, or appear spalling phenomenon, with black spots on the surface, uncooked, no flavor, serious decay.
Cucumber, green pepper
Cucumber and green pepper will turn black, soft and sour when stored in refrigerator for a long time. Cucumbers also grow sticky hair. Because the temperature stored in the refrigerator is generally about 4 ℃ to 6 ℃, while the suitable temperature for cucumber storage is 10 ℃ to 12 ℃, green pepper is 7 ℃ to 8 ℃, so it is not suitable for long storage.
Green leafy vegetables
Green leafy vegetables placed in the refrigerator will not only rot the leaves faster, but also produce toxic nitrite due to the action of enzymes and bacteria.
The 10 kinds of food that should not be put in the refrigerator are the most. You may often put them in the first one.
If bananas are stored below 12 ℃, they will turn black and rot.
If litchi is left at 0 ℃ for one day, its skin will turn black and its pulp will turn sour.
Strawberry is stored in refrigerator, not only the pulp is foaming, the taste is greatly reduced, but also it is easy to mildew.
