The shelf life of honey is usually 18 months.

Honey crystallizes at low temperatures. The part that crystallizes is glucose and the part that does not crystallize is mainly fructose. Honey should be stored in a cool place, preferably in the refrigerator, and should not be placed in direct sunlight, usually with a shelf life of 18 months.

Because honey is a weakly acidic liquid, it can react chemically with metals, and chemical reactions will occur when it comes into contact with metals such as lead, zinc and iron during storage. Therefore, non-metallic containers such as ceramics, glass bottles non-toxic plastic buckets and other containers should be used to store honey. National regulations for bottled honey shelf life of 18 months, but capped mature concentration of honey can also be preserved for many years. But eating honey fresh is good, because fresh honey is generally better color, aroma, taste and texture.

Honey and preservation methods:

1, heating to prevent fermentation

Hot summer, honey at room temperature is very easy to Ru fermentation. Found that this situation, you should be honey in a glass container, placed in a pot of water heated to 63 ℃ ~ 65 ℃, insulation for 30 minutes, you can stop the fermentation.

2, sealed preservation

Generally eaten at home honey are filling, eat a little bit to pour out a little bit, and then covered with a lid seal, this cover does not have any effective sealing measures, air and bacteria are easy to enter. So when choosing honey, you can either choose a small jar that you can eat in a few days, or buy a small bag and eat one bag at a time. If unfortunately you buy a large jar, it's okay to buy a roll of plastic wrap and just put the lid on first and then wrap the bottle with the plastic wrap after each serving.

3, ginger slices to prevent deterioration
