摘    要:我国是海藻生产大国,藻类是人们喜爱的健康食品.但新的海藻制品卫生标准和食品中无机砷检测方法标准实施后,依照该标准检测发现海藻中的无机砷超标问题十分严重.为探讨其原因,调查了国内外的紫菜、海带等产品总砷、无机砷含量,分析了不同收割期的鲜紫菜及其加工制品以及养殖区域水质中无机砷变化情况.结果发现:按新的卫生标准及其检验方法检测,海藻中无机砷普遍超标;紫菜中的无机砷与养殖区水质中无机砷含量的变化并非成线性关系;GB/T 5009.11中的两种测定方法对海藻中无机砷的检测结果有明显差异,不适用于海藻中的无机砷检测.

关 键 词:海藻  无机砷  检测方法

Abstract:China is a big country with seaweed production, and seaweed is the peoples favorite health food. However, since the new sanitation standard and testing standards were issued, in accordance with the new testing standards, we found that the over-standard of inorganic arsenic was very serious in the seaweed. In order to explore its cause, this paper surveyed the inorganic arsenic content of some seaweed products such as laver and kelp which come from home and abroad, and we also carried out tracking detection the determination of inorganic arsenic of the different harvest period fresh laver and the laver products, and aquaculture regional water. We found that in accordance with the new sanitation standard and testing standards, the over-standard of inorganic arsenic was a common problem; it was related to the inorganic arsenic content of aquaculture regional water, but not a linear relationship. In the experimentation, we used two methods of the GB/T5009.11 to determinate the inorganic arsenic in seaweed, the distinction of data was very greatly. And these two method were all not suitable to determinate the inorganic arsenic in seaweed.
Keywords:seaweed  inorganic arsenic  over-standard  research
