Abstract

Cancer pagurus is much appreciated in Southern Europe, where the muscle, hepatopancreas, and gonads are consumed regularly with peaks in summer and December. The elemental contents of C. pagurus edible tissues were analyzed in this study during the four seasons. Results indicate that the content varied with tissue, season, and sex. The hepatopancreas had more S, Cl, Ca, Br, Sr, Fe, Cu, Cd, and Pb, the gonads had a higher concentration of Na, and the muscle was richer in Zn. Autumn and winter corresponded to a high Mg, S, Cl, K, Ca, Fe, and Zn content in both the muscle and hepatopancreas. Female gonads had more Fe, Zn, As, and Se than males but less Ca, Cl, Br, and Sr. Regarding toxic elements for human consumption, the levels of As, Hg, and Pb found in all edible tissues pose minimal risks to consumers. However, Cd concentration in the hepatopancreas was always above the action limit. Therefore, we recommend moderate hepatopancreas consumption.

摘要

黄道蟹在南欧备受青睐，其肌肉、肝胰腺和性腺常被食用，夏季和12月食用量达到高峰。本研究分析了四季中黄道蟹可食用组织的元素含量。结果表明，含量因组织、季节和性别而异。肝胰腺含有更多的硫、氯、钙、溴、锶、铁、铜、镉和铅，性腺中钠的浓度较高，而肌肉中锌含量更丰富。秋季和冬季，肌肉和肝胰腺中的镁、硫、氯、钾、钙、铁和锌含量较高。雌性性腺中的铁、锌、砷和硒含量高于雄性，但钙、氯、溴和锶含量较少。就人类食用的有毒元素而言，所有可食用组织中发现的砷、汞和铅含量对消费者构成的风险极小。然而，肝胰腺中的镉浓度始终高于行动限值。因此，我们建议适量食用肝胰腺。
