Staple foods such as rice and steamed bread are best eaten the next day, because starchy foods are easy to breed staphylococci and aflatoxins. These harmful substances cannot be killed by high temperature heating. So, if you haven't finished eating for two days, don't eat any more, even if it doesn't look bad.

It's much easier to steam rice at home once. In addition to fried rice and porridge, you can also break the leftovers and add tofu and eggs to make rice paste tofu soup. In addition, rice can also be mixed with potatoes and minced meat to make dry fried meatballs.

Key points of leftovers storage-

1, leftovers need to be thoroughly cooled before they can be put into the refrigerator. This is because the hot food suddenly enters the low temperature environment, and the food center is prone to qualitative change. The hot air brought by the food will cause the condensation of water vapor, promote the growth of mold, and lead to the moldy food in the whole refrigerator.

2. Harmful bacteria in the air will attach to some high-protein and high-fat leftovers and reproduce within 2 hours. Under the action of bacteria, protein and fat will produce harmful substances, such as hydrogen sulfide, amines and phenols. It is harmful to human body. Therefore, leftovers should be put in the refrigerator within two hours after cooking and put in shallow containers to facilitate cooling.
