How to heat leftovers? The best time to store leftovers is not every other meal. The leftovers in the morning should be eaten at noon, and the leftovers at noon should be eaten in the evening. It's best to eat it in 5-6 hours. Because under normal circumstances, through the high temperature of 100 degrees Celsius heating, a few minutes can kill some bacteria, viruses and parasites. However, if the food is stored for a long time, the bacteria in the food will release chemical toxins, which can not be heated.
1. The packaged food needs to cool thoroughly before putting into the refrigerator.
This is because the hot food suddenly enters the low temperature environment, the food center is prone to qualitative change, and the hot gas brought in by the food will cause the condensation of water vapor, promote the growth of mold, thus leading to the mildew of the whole food in the refrigerator.
2. Packaged food must be returned to the pot.
The food stored in the refrigerator must be returned to the pot after it is taken out. This is because the temperature of the refrigerator can only inhibit the growth of bacteria, not completely kill them. If you don't heat it before eating, it can cause discomfort after eating, such as diarrhea or diarrhea.
3. The storage time of leftovers should not be too long.
The best time to store leftovers is not every other meal. The leftovers in the morning should be eaten at noon, and the leftovers at noon should be eaten in the evening. It's better to eat it in 5-6 hours. Because under normal circumstances, through the high temperature of 100 degrees Celsius heating, a few minutes can kill some bacteria, viruses and parasites. However, if the food is stored for a long time, the bacteria in the food will release chemical toxins, which can not be heated.
It's important to deal with the leftovers. Of course, it is best not to leftovers, according to the amount of rice under the pot. If it is left, the leftovers should be loose and put in a ventilated, cool and clean place to avoid pollution.
4. Vegetables should not be packed.
Because in the process of vegetable production, generally less salt is used. When a good vegetable is put under high temperature for a long time, a large number of bacteria will breed in the vegetable, and nitrate will be reduced to nitrite under the action of bacteria. Nitrite is easy to synthesize nitrosamine with amine in nature. Nitrosamine is a strong carcinogen. If we eat leftover vegetables for a long time, it is not good for our health. For example, if we eat salted vegetables for a long time, we will have a higher risk of gastric cancer.
After a long time of salting, the salt on the surface of the leftover vegetables will turn into nitrite when heated repeatedly, which is most likely to cause poisoning.
