1. Refrigerator storage: blanch cicadas in boiling water, then drain and store them in the refrigerator, which can be stored for several days without turning black.

2. Vacuum storage: cicada monkeys are treated with boiling water, drained, put into a vacuum device and exhausted, and can be stored for more than one month without turning black.

3. Spray freezing: After the cicada is cooked, spray a layer of cold boiled water after the surface is dry. After repeated several times, a thin layer of ice will form on its surface, which can be preserved for several months.

4. Salting: After the cicada is cooked, apply a layer of salt on the surface, and then put it in a fresh-keeping bag for freezing, which can be stored for several months.

Among the above methods, frozen storage in refrigerator and vacuum storage are the two most common methods.
