It is common to use the refrigerator to store ingredients, but do you know which foods cannot be stored in the refrigerator? Look at the blacklist of foods that can cause cancer in the refrigerator, do you have these foods in your refrigerator? Cucumber cucumber in the refrigerator for a long time, will appear frozen “injury” – black, soft, tasteless. Cucumber will also grow hair sticky. Because the refrigerator storage temperature is generally 4 ℃ to 6 ℃ or so, and cucumber storage suitable temperature for 10 ℃ to 12 ℃, 7 ℃ to 8 ℃ for peppers, so should not be stored for a long time. Cucumber, eggplant, tomatoes, etc., the appropriate storage temperature of 7.2 ℃ to 10 ℃. Chocolate The chocolate put into the refrigerator after taking out, the surface is easy to appear white frost, not only lose the original mellow taste, but also conducive to the reproduction of bacteria. The best temperature to store chocolate is 5℃-18℃. In summer, when the room temperature is too high, you can first use plastic bags sealed, and then placed in the refrigerator freezer storage. When you take it out, do not open it immediately, let it slowly return to room temperature before eating. Bread During the baking process, the straight chain division of starch in the flour has aged, which is the reason for the elasticity and soft structure of the bread. As the bread is left for a longer period of time, the straight chains of the branched starch in the bread slowly join together, causing the soft bread to gradually harden, a phenomenon called “aging”. The rate of “aging” is temperature dependent. In the low temperature (above the freezing point) aging faster, and bread in the refrigerator, the degree of hardening comes more quickly. Fish can not be put too long refrigerator fish should not be stored for too long, home refrigerator refrigeration temperature is generally -15 ℃, the best refrigerator can only reach -20 ℃, and aquatic products, especially fish, in the storage temperature did not reach -30 ℃ below, the fish body tissue will be dehydrated or other changes, such as carp long time refrigerated, it is easy to appear fish body sour, meat quality changes, inedible. Therefore, the fish stored in the refrigerator should not be too long. Chinese medicine should not be placed in the refrigerator, herbs into the refrigerator, and other food mixed for a long time, not only a variety of bacteria are easy to invade the herbs, and easy to moisture, destroy the medicinal properties of the herbs, so some valuable herbs, such as ginseng, antler, asparagus, ginseng, etc., if you need long-term preservation, can be placed in a clean glass bottle, and then put the right amount of glutinous rice fried to dark yellow with a gentle fire, to be cooled into, the Seal the lid tightly and set aside in a cool, ventilated place.
