1. Silkworm pupae can be stored in the refrigerator. Remember to wrap it with plastic wrap before storage. If it is frozen in the refrigerator, it can be kept for about half a year. If the silkworm chrysalis is still alive, it will freeze to death in less than 2 hours in the refrigerator.

2. Preserve the silkworm chrysalis, or you can cook the silkworm chrysalis and preserve it after salting. This method should be stored at room temperature, but the storage time depends on the season. Generally speaking, 1~2 weeks can be preserved in autumn and winter, and 1 week can be preserved in spring and summer, which is the best before that.

3. Fresh silkworm chrysalis can be soaked in salt water for 2~3 hours before being stored in the refrigerator, which can play the role of sterilization and insecticidal. Because there may be tiny parasites in the forelimb nests and abdominal folds of silkworm chrysalis, it is safer to eat with salt and the storage time will be longer.

4. Silkworm pupae can be sealed with fresh-keeping bags or plastic bags, and then frozen in the refrigerator. After the silkworm chrysalis is frozen, it must be fully thawed before the next consumption. If you fry it, you must fry it thoroughly, especially the belly. You can press the belly of silkworm chrysalis with a shovel and fry it. You can't eat safely until your stomach is fried thoroughly.
