Which foods should not be stored in the refrigerator?
Banana: Storage in an environment below 12 will cause it to rot black. Cucumber: Put it in the refrigerator at 0 degrees for three days, the skin will be water-immersed and lose its flavor. Tomatoes: After freezing, some or all of the fruits will be soaked in water and appear brown round spots. The meat is blistered, appearing soft and rotten, or spalling, with dark spots on the surface, uncooked, no umami, and severe rot. Cucumbers, green peppers: Cucumbers, green peppers in the refrigerator for a long time, there will be "frozen wounds" - black, soft, and taste. Cucumbers also have long hair sticks. Because the temperature stored in the refrigerator is generally about 4 to 6, and the suitable storage temperature for cucumber is 10 to 12, and the green pepper is 7 to 8. Therefore, it is not suitable for a long time. During the baking process, the amylose fraction in the flour has aged, which is why the bread produces an elastic and soft structure. As the prevention time prolongs, the linear chain of the amylose fraction in the bread slowly associates, and the soft bread gradually hardens. This phenomenon is called "changing". The speed of aging is related to temperature. In the low-temperature greenhouse, it is harder to make the bread in the refrigerator faster than the room temperature. Therefore, if it is stored for a short time, the bread should be placed at room temperature to prevent the bread from becoming hard. Leave the leftover mooncakes in the refrigerator. Moon cakes are baked and baked with ingredients such as flour, oil, sugar and nuts. Baked goods should not be stored in the refrigerator. Although for some varieties of moon cakes, putting in the refrigerator can extend its shelf life, but it will affect its flavor. In addition, Chinese herbal medicines should not be placed in the refrigerator. The medicinal materials are placed in the refrigerator and mixed with other foods for a long time. Not only are various bacteria easily invaded into the medicinal materials, but also easily damp and destroy the medicinal properties of the medicinal materials. Fresh lychee: Put it on for one day in an environment below 0 degrees, the skin will turn black and the flesh will taste. Leaf dish: Because it is easier to rotten after it is refrigerated. Fresh fruit juice: It is easy to destroy its vitamins and other nutrients after freezing! The suitable storage temperature for cabbage, celery, onions, carrots, etc. is about 0. Beer: If it is lower than 0, the appearance is turbid and the taste is not good. Therefore, beer should not be stored in the refrigerator any season. Do not put bottled liquid beverages into the freezer to avoid cracking the bottles. It should be placed in the refrigerator or on the door, and stored at a temperature of about 4 is the best. Pumpkins are suitable for storage at 10 or more. After the chocolate is refrigerated in the refrigerator, once it is taken out, a layer of hoarfrost will form on the surface at room temperature, which will easily become moldy and lose its original taste. If the ham is placed in the refrigerator at low temperature, the water will freeze and the fat will precipitate. The ham will be agglomerated or loose, and the meat will taste bad and it will be easily spoiled. Frozen foods should not be stored after thawing: Frozen foods bought from the market, meat, fish, chicken, duck, eggs, frozen vegetables, etc., should be processed as soon as possible after thawing, and should not be stored. If the storage time is too long, meat, fish, chicken, ducks, etc. will recover due to the vitality of bacteria and enzymes, not only can quickly degenerate and decompose proteins to cause deterioration, but also produce toxic histamine substances, which can cause food poisoning when eaten. Frozen vegetables are stored for too long, not only color change, nutrient loss, quality decline, but also very easy to rot and deteriorate, can not be eaten. When frozen meat, fish, chicken, duck, etc. are frozen, the tissue cells are destroyed by the action of water crystallization. Once thawed, the destroyed tissue cells will ooze a large amount of protein, which becomes a nourishment for bacterial reproduction. . Experiments have shown that freshly frozen mackerel, which has been frozen for 1 day, is kept at a temperature of 30 for 6 hours, which is twice as fast as fresh fish; the yolk is thawed at 18 for 2 hours, and the number of bacteria is increased by about 2 Times, after 8 hours, the number of bacteria increased by more than 50 times; the frozen fresh eggs were placed at 0~15 for more than 10 days, because the change of cold and hot temperature was too long, not only the egg membrane became loose, the egg white was thin. And it also occurs in the shell, yellow, and even mildew, smell, can not be eaten; frozen vegetables, especially in hot days, should not be stored, otherwise the green leafy vegetables will soon turn yellow, vitamin C is also easy to be destroyed. When the vegetables are placed at a temperature of 20, the decomposition loss of vitamin C is twice as high as that at a temperature of 6-8.
