1. The black stuff inside the silkworm chrysalis can be eaten. The silkworm chrysalis itself is the intermediate process between silkworms turning into moths. Through the process of the moth breaking out of the cocoon, you can know that the black strips in the silkworm chrysalis are actually its "real body". The black shell of the silkworm chrysalis looks similar to that of the silkworm, which is the outer shell of the silkworm. Just the skin.

2. The white between the outer skin and the black strip is high-purity protein, which is the source of the aroma and nutrition of the silkworm chrysalis. The black strip is not feces, but the neuronal body of the silkworm. There will be no adverse reactions if eaten, and it is completely non-toxic. The black stuff inside is not spoiled, even if it is alive, it is there. It is just an organ in the body, which is okay. It is just like the digestive system in our body, it is not poisonous.
