Pollen storage and sterilization
Pollen storage methods: First, frozen storage: dry pollen before storage with a double plastic bag, and sealed bag mouth to prevent water absorption. For short-term storage, storage temperature is maintained at 0-5 °C; long-term storage temperature is maintained at -20 °C ~ -18 °C. Minimize the loss of protein and vitamins in pollen and avoid moldy worms. Second, the white sugar storage: prepare a small amount of pollen for their own consumption, in order to prevent pollen deterioration in the short term, can be mixed with white sugar, pollen, and then into the bottle compaction, and add 3 to 5 cm in the upper white sugar, sealed Bottle mouth, keep in dark place.
