The best way to store fresh ginkgo is refrigeration. If the indoor room temperature is above 27 degrees Celsius, it is useless to put ginkgo in the refrigerator. Because the refrigerator door is often opened, the room temperature will escape into the refrigerator, so it will still deteriorate. Therefore, it is the best choice to put ginkgo in the freezer. And ginkgo nuts can be kept fresh in the freezer.

2, canned preservation

Find several sealed glass bottles, pour the ginkgo into the bottles, and seal the bottle mouth, so that air and other bacteria can't touch the ginkgo. This storage method can also make the ginkgo stored for a long time.

3, vacuum bag preservation

If time permits, you can buy that kind of small air pipe for pumping air, and then buy that kind of plastic bag for storing food. After putting ginkgo into the plastic bag, use the small air pipe to pump all the air inside the plastic bag, and then seal the plastic bag.

Precautions for preservation of fresh ginkgo

In order to better store and keep ginkgo fresh, it is necessary to judge whether the peel of ginkgo changes from green to yellow and from hard to soft when harvesting, and the harvesting time should be sunny morning or cloudy day, and it is forbidden to harvest in rainy days to avoid rot during storage.

The suitable storage temperature of ginkgo biloba is 4℃, and attention should be paid to the stability of the storage temperature, the safe storage temperature should be controlled at1℃, and the fluctuation of the storage temperature should not exceed 2℃. Excessive temperature fluctuation will easily lead to mold growth, yellowing and deterioration. In order to delay the softening and wilting of ginkgo due to water loss, the relative humidity of ginkgo storage should be kept at 70%-80%. If the humidity is insufficient, you can spray water on the ground, and if the humidity is too high, you can also ventilate properly to keep the humidity in the warehouse stable.
