But most food has nitrite, content is very few, even if put grew to add nitrite content, also won't cause a harm to the person. Certain and vegetable, be like Chinese cabbage, the content of nitrite can increase many a little bit, reduce edible had better.
Dish of of the previous night of a lot of moment is to save undeserved metamorphism, eating the harm to the person just is terrible. Occasionally we had not become aware to taste badly, had happened character changeably, ate bad. So dish of of the previous night should last film or last the box is sealed, again freezer lasts, putting 10 hours is eatable.
