【摘要】 就我国近海海带中砷含量、砷的存在形态及其毒性、国内外相关标准中砷的限量、砷检测方法及脱砷技术等5方面的问题,综合阐述并分析前人对海带中有害元素砷的研究状况。据此,并结合我们的工作,提出关于海带脱砷研究的现状、面临的问题及可能的前景:根据砷的价态、形态及毒性机理,海带中具有毒性的砷的形态为无机砷;我国国标(2005版)对干海藻无机砷的限量(≤1.5 mg/kg),而国产海带无机砷含量已超国标;提取分离技术是海带深加工产业的基石,此过程实际上富集了提取物中的砷,在国内外少有海藻提取物砷限量的背景下,建议参照国际食品添加剂标准中特定海带提取物中无机砷限量(≤3 mg/kg)。更多还原

【Abstract】 This review focuses on five aspects issues, namely, the arsenic content in Chinese kelp, the presence form and toxicity of arsenic, as well as the arsenic limit content, the method of detection arsenic, and the technology of removing arsenic in standards at home and abroad. The limit of inorganic arsenic in S. japonica is over the national standards for dried algae(≤1.5 mg/kg). In fact, inorganic arsenic is also accumulated while extracting target substance. Therefore, the limits of inorganic arsenic in the kelp extract should be referred to the international standards for food additives(≤3 mg/kg) due to lack of the standards on inorganic arsenic limit for extract of algae.更多还原
