中文摘要:

      海洋贝类由于滤食性特点而极易受到重金属的污染。近年来我国海洋贝类普遍出现重金属超标问题, 严重影响了我国贝类食品安全和出口贸易, 因此重金属的脱除技术逐渐受到重视。 本文综述了海洋贝类的污染 现状, 介绍了海洋贝类重金属脱除技术与方法, 包括活体贝类脱除法和蛋白酶解液脱除法, 同时对脱除技术的 未来发展进行了展望。

英文摘要:

      Marine shellfish are easily polluted by heavy metal because of its characteristic of filter-feeding. In recent years the problems of heavy metal over standard level polluting Chinese shellfish have emerged pre- valently, which has seriously affected the food safety and export trade of China. Thus, the removal technology of heavy metal is getting more and more concern. This review summarized the current status of cadmium pol- lution in marine shellfish, introduced cadmium removal technologies including live shellfish removal method and protease hydrolyzate removal method. At last the paper suggests a prospect of the development on removal technology.
