How long tofu can be stored in the refrigerator depends on the specific storage method: put it directly in the refrigerator without any treatment, up to 2 days. If tofu is put in a dish with little salt water, it can be kept in the refrigerator for about 3 days. Tofu can also be stored for 3 days if it is directly sealed with plastic wrap and put in the refrigerator. If there is vacuum equipment at home, vacuum package tofu, and then put it in refrigerator for 7~ 15 days.

Tofu is a nourishing, heat-clearing and health-preserving food. Regular eating can tonify the middle energizer, clear away heat and moisten dryness, promote fluid production to quench thirst and clear the stomach. It is more suitable for people with heat constitution, bad breath, thirst, indigestion and fever. Modern medicine has proved that tofu not only has the function of increasing nutrition, helping digestion and stimulating appetite, but also is quite beneficial to the growth and development of teeth and bones. Tofu is sweet and cool, and has the effects of invigorating qi, harmonizing middle energizer, promoting fluid production, moistening dryness, and clearing away heat and toxic materials. However, although tofu is good, eating more has disadvantages, and excessive consumption will also endanger health.

For example, it causes indigestion, and tofu is rich in protein. Eating too much at a time not only hinders the absorption of iron, but also easily causes symptoms such as bloating and diarrhea. In particular, patients with gout eating tofu will aggravate the attack of gout: tofu contains more purines, and patients with gout with abnormal purine metabolism and patients with elevated blood uric acid concentration are prone to gout attacks, especially gout patients should eat less.
