Five kinds of overnight dishes can't be eaten
"Overnight food" does not only refer to the food that has been put overnight. If it is put for more than 8-10 hours, it should be regarded as overnight. There are two reasons for the increase of toxic ingredients in food. The first is that the chemicals in food produce carcinogens, such as nitrite, which can not be removed even when heated. Another reason is secondary contamination by foreign bacteria when placed. The following vegetables are particularly harmful if kept for a long time.
Leafy greens are the most dangerous overnight. Generally, the nitrate content of stem and leaf vegetables is the highest, melon vegetables are slightly lower, and rhizome and cauliflower are in the middle. Therefore, if you buy a large number of vegetables at the same time, you should first eat leafy vegetables, such as cabbage, spinach, etc. If you are going to cook more vegetables and eat them hot the next day, you should try to do less stem and leaf vegetables and choose melon vegetables.
Overnight seafood damages the liver and kidney. Crab, fish, shrimp and other seafood will produce protein degradation products overnight, which will damage liver and kidney functions. If you buy too much, you can use fresh-keeping bags or boxes to pack the raw seafood, put it in the refrigerator for freezing, and cook it next time.
Half cooked eggs are susceptible to disease. Many people like to eat half cooked eggs with soft yolk. However, this kind of eggs are not completely sterilized. In addition, the eggs are rich in nutrition, which is particularly easy to breed bacteria. After eating, it will be dangerous. If the eggs are well cooked and properly sealed at low temperature, it's OK to eat them overnight.
Be careful of Tremella mushroom. No matter it is wild or cultivated tremella, mushroom, etc., it is easy to leave a lot of nitrate. If the time is really a little long, we can only bear to throw it away.
Don't put the soup in the metalware. It takes time and effort to cook soup. People often cook a big pot and eat it for several days in a row. If the leftover soup is kept in an aluminum or iron pot for a long time, harmful substances will be separated out. The best way to store the soup is not to put salt and other seasonings in the soup. When the soup is cooked, use a clean spoon to take out what you want to drink that day. If you can't finish it, it's better to use a tile pot or a fresh-keeping box to store it in the refrigerator.
