Soak silkworm chrysalis in salt water for 2 to 3 hours. Can play the role of sterilization and insecticidal. Then sealed with plastic bags and frozen in the freezer. If there are not many pupae, they can be frozen in a container filled with water. Thaw fully when eating and fry thoroughly when frying. Use a shovel to press the belly of the silkworm chrysalis and fry it thoroughly before eating.

Live silkworm chrysalis with cocoon, if the local temperature is around zero. Cicadas can be kept outdoors. If the local temperature is below 0 degrees, it is best to store it indoors without heating facilities. In addition, silkworm chrysalis can be cooked with boiling water and salt, cooled and quickly frozen in the refrigerator. The storage time will be longer, but the taste of frozen cicada pupa is not as good as that of fresh pupa.
