First pick out and throw away the spoiled and blackened edamame and other impurities, and then suck out the excess water of edamame, which can be put in plastic bags and stored in the refrigerator 1 month.

It can be preserved for half a year to one year, so that the preserved edamame can retain the fresh flavor to the maximum extent.
