The shelf life of tofu is relatively short, depending on the temperature and how long it can be preserved. Generally speaking, in cold weather, tofu stored in the refrigerator for three days has not deteriorated and can be eaten.
However, in hot summer, tofu may go moldy and deteriorate in the refrigerator for three days, so try not to eat it. Tofu can be kept in the refrigerator for about two days at most in summer.
