| 摘 要： | 为降低瘤背石磺(Onchidium struma)体内超标重金属铜和镉的含量,保证其食品安全,作者通过底泥添加木鱼石土(富含锌、硒等)、饲料添加蛋白核小球藻(Chlorella pyrenoidosa)粉以及维生素C对瘤背石磺体内Cd和Cu进行净化,探究不同实验组对瘤背石磺体内Cd和Cu的净化效果。结果表明,对照组单纯用玉米粉暂养对瘤背石磺重金属的排出有一定的效果,但远远低于试验组在底泥中添加木鱼石土、在饲料中添加蛋白核小球藻粉及维生素C的效果。在瘤背石磺产品生产过程中,通过在底泥中添加木鱼石土、在饲料中添加蛋白核小球藻粉及维生素C能高效地降低其体内重金属铜和镉的含量,达到可食用的目的,保证食品安全。

| Abstract: | In this study, the depuration of the exceeding Cd and Cu in Onchidium struma by adding Muyu-Stone rich in Zn and Se to the habitat sediment or adding Chlorella pyrenoidosa powder or Vitamin C in the feed was compared in order to find out the best one. The results showed that corn flour alone had certain effect on the discharge of heavy mental in control group, but it was far less than that of Muyu-Stone, C. pyrenoidosa powder or vitamin C in experimental group. The contents of heavy mental Cd and Cu in O. struma were efficiently reduced, so this method can be applied in the producing process to guarantee the food safety. |
