Introduction
In general, whether the black part on the edge of jellyfish head is edible depends on the preservation condition of the jellyfish and the nature of the black portion. When selecting jellyfish heads, choose those with thick flesh and a translucent appearance. After purchasing, promptly soak and rinse them in clean water to remove impurities and excess salt. For short-term storage, keep them refrigerated and consume within two days if possible.
Generally, whether the black part on the edge of jellyfish head is edible depends on the preservation condition of the jellyfish and the nature of the black portion. The specific analysis is as follows:
If the black portion on the edge of the jellyfish head is only a thin surface layer, and the overall texture of the jellyfish is firm and elastic, with no fishy or sour odors or other unpleasant smells, and there are no signs of stickiness or mold on the surface, this blackness is usually due to natural pigment deposition in the jellyfish itself or slight oxidation marks. After thorough washing, it is safe to eat and will not cause any adverse effects on the body.
However, if the black portion on the edge of the jellyfish head is thick, accompanied by soft, mushy texture that breaks apart easily when pinched, emits a strong fishy or rotten smell, or even shows visible mold spots or mucus on the surface, this indicates that the jellyfish has spoiled. In such cases, the black areas are most likely caused by mold growth or decomposition and must not be consumed, as doing so may lead to gastrointestinal discomfort.
When selecting jellyfish heads, choose those with thick, firm flesh and a translucent appearance. After purchasing, promptly soak and rinse them thoroughly in clean water to remove impurities and excess salt. For short-term storage, keep them refrigerated and consume within two days to prevent spoilage from prolonged storage.
