First, save the container.
The PH value of royal jelly is about 3.5 ~ 4.5. As a whole, it belongs to acidic viscous liquid and must not be stored in metal containers such as iron, aluminum and copper. The reason is that royal jelly will react with metals for a long time, which will affect the shelf life. It is best to choose non-toxic plastic bottles or glass bottles, and the containers should be cleaned, disinfected and dried before use.
Second, the low temperature environment
Temperature is an important factor affecting the shelf life of royal jelly. It is best to put royal jelly in the refrigerator for short-term storage, and in the freezer for long-term storage.
Third, avoid light.
Royal jelly is very sensitive to light, because light can promote the reduction of ketone groups and aldehyde groups in royal jelly, thus accelerating the deterioration of royal jelly and losing its edible value. Therefore, royal jelly must be stored in a dark environment, and it is best to choose brown and black glass bottles or milky non-toxic plastic bottles as storage containers.
Fourth, sealed preservation.
The air contains a lot of moisture and microorganisms, which are also important factors affecting the shelf life of royal jelly. Therefore, royal jelly must be sealed when stored, and it is best to seal the bottle mouth with beeswax for a long time.
