1. Generally speaking, pure natural honey has a shelf life. According to national regulations, the shelf life of honey must be marked as two years. However, many honeys on the market are marked with 18 months. According to Chinese food safety standards (GB7718) stipulates that except for wine, vinegar, and solid sugar with a temperature of more than ten degrees, all other foods need to be marked with a shelf life. It can be seen that honey has a shelf life of two years, which is a food that is relatively resistant to storage. The shelf life is to ensure the honey’s shelf life. In terms of safety and quality, honey that has passed its shelf life is generally not edible.

2. Honey is actually an insulator for bacteria, but honey is hygroscopic. After it is opened, it easily absorbs moisture in the air, produces oxidation, and decomposes the sugar in it. This will cause the honey to deteriorate and cause wine to appear. It tastes bad and is basically no longer edible. Honey is rich in glucose and fructose and has very low water activity, which is not suitable for microorganisms to survive. Pure natural honey is acidic and bacteria cannot reproduce quickly, so honey can be stored for a certain period of time, but It won't take too long. If the temperature of storing bees is too high, the honey will deteriorate and become very thin. At this time, the nutritional value of the honey will become very low, and the taste will be very sour. Basically, it can no longer be eaten. Therefore, everyone should pay attention to the shelf life of honey and avoid eating expired honey.
