Analysis:

Excuse me, landlord, is it inappropriate to put it in the refrigerator?

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

After tomatoes are frozen at low temperature, the flesh of tomatoes is blistered, soft and rotten, or cracked, with black spots on the surface, immature and tasteless, and even rotten in severe cases.

Bananas will turn black and rot when stored below 12℃.

Fresh Litchi If Litchi is left at 0℃ for one day, the skin will turn black and the pulp will go bad.

After the chocolate is put into the refrigerator, once it is taken out, it will form a layer of frost on the surface at room temperature, which is easy to go moldy and deteriorate and lose its original flavor.

Ham If ham is kept in the refrigerator at low temperature, the water in it will freeze, the fat will precipitate, the ham meat will agglomerate or loosen, and the meat will become stale and perishable.

Bread: In the baking process, the linear segment of starch in flour has aged, which is the reason why bread has elastic and soft structure. With the extension of storage time, the linear part of amylopectin in bread slowly associates, which makes the soft bread gradually harden. This phenomenon is called "aging". The speed of "aging" is related to temperature. At low temperature (above freezing point), bread will age faster, but after being put in the refrigerator, the degree of hardening will come faster.

Cucumber and green pepper: Cucumber and green pepper will freeze and "hurt" if put in the refrigerator for a long time-turn black, soften and taste bad. Cucumbers also have sticky hairs. Because the temperature of refrigerator storage is generally around 4℃ to 6℃, the suitable storage temperature of cucumber is 10℃ to 12℃, and the suitable storage temperature of green pepper is 7℃ to 8℃. So it shouldn't last long.
