If the porridge is not finished at once, put the remaining porridge in a food packaging box, cover it with a lid or plastic wrap, and put it in the refrigerator for refrigeration. The cold storage temperature of the refrigerator is low, which can relatively slow down the deterioration speed of porridge. If the porridge is taken out of the refrigerator overnight, it can be eaten normally without foaming, odor, mildew and other deterioration phenomena. But before eating, it is necessary to heat the porridge overnight to avoid gastrointestinal irritation and abdominal pain caused by eating cold food.
If the porridge is stored in the refrigerator overnight, it is not sealed or the refrigerator door is not closed tightly, which may lead to the deterioration of the porridge stored in the refrigerator, or the porridge stored at room temperature for a long time before being put in the refrigerator has deteriorated, resulting in foam, odor and mildew. It is not recommended to eat deteriorated porridge, so it should be discarded in time to avoid bacteria and other pathogenic microorganisms stimulating the digestive system, causing abdominal pain, diarrhea and other discomfort, affecting health.
