Mushrooms belong to the fungus food, although it is fried can be eaten overnight, generally save in the refrigerator will not happen basically deterioration. But again to eat must be fully heated to do, because put the next day's meals are easy to breed bacteria, the gastrointestinal impact, and again heated food nutrients will be lost, the taste is not so good.

So I suggest that mushrooms fried or consumed on the same day is better.
