The shelf life of honey is generally 18 months or 2 years, which is a kind of food with long shelf life. Expiration and deterioration are often closely related in everyone's impression, but honey expiration does not mean deterioration. Because honey is nectar or secretion of plants collected by bees, it is fully brewed. The water content of mature honey is less than 20%, and it also contains acidic substances and high concentration of sugar, which can inhibit the growth and reproduction of many bacteria. Therefore, if honey is well preserved, the storage time will exceed the shelf life, and it will not deteriorate after expiration.

Therefore, if the expired honey has not deteriorated, everyone can continue to eat it. However, if there is deterioration, slightly deteriorated honey also has many wonderful uses. If honey is heated to 60 degrees for half an hour, the yeast can be killed, the foam on it can be removed, and then it can be sealed and stored, which can be used for bathing and hair care. When taking a bath, apply the skin as emulsion, fully massage for 2-3 minutes, and then rinse off.
