Introduction

The black, paste-like substance in crab roe is actually the undeveloped shell of the crab and is edible. When eating crabs, always ensure the ingredients are fresh and avoid consuming spoiled or dead crabs.

For any parts whose edibility is uncertain, it's best to consult a professional or follow reliable recipes.

Generally speaking, the black paste-like substance on crab roe is actually the undeveloped shell of the crab and is edible. The detailed explanation is as follows:

During the growth process of crabs, their shells undergo multiple molts to accommodate body growth. The black, paste-like material on the crab roe is typically an incompletely shed or absorbed shell, which is a natural phenomenon in the crab's development. Although its texture may differ from that of a mature shell, it is essentially still part of the crab's body and may contain certain minerals and trace elements. It is non-toxic. Therefore, provided the crab is fresh and properly cleaned, this substance is safe to eat.

When consuming crabs, always ensure the ingredients are fresh and avoid eating spoiled or dead crabs. During preparation, thoroughly clean the crabs to remove unnecessary impurities and residues. For any parts whose edibility is uncertain, it is best to consult a professional or refer to reliable recipes for guidance.
