Preservation of bee pollen

　　Bee pollen needs to be dried, sealed or stored under freezing conditions, otherwise it will be easily damaged by insects and molds, which will reduce the nutritional value.

　　(1) Cold storage: put the bagged and sealed bee pollen into the cold storage, and the storage temperature is between - 1 ℃ and - 5 ℃. The ideal effect can be achieved. The effect of low-temperature storage will be better. Fresh bee pollen can be stored for several years in a cold storage, refrigerator or low-temperature freezer at - 18 ℃ to - 20 ℃, and will not deteriorate. The effect is basically the same as that of fresh bee pollen just harvested.

　　(2) Storage at normal temperature: if there is no condition but it can only be stored at normal temperature, the bee pollen must be dried, sealed with thick plastic bags, and stored under dry conditions with good ventilation. The dried bee pollen can also be put into the sterilized colored glass bottle. The bottle mouth is sealed with beeswax and can be stored for 6-12 months in the dark. Bee pollen can also be packed in cloth bags and packed in 1-3 layers of plastic bags, which can be stored for 2-6 months.
