摘要
通过对鲜活水产品中甲醛本底含量的调查研究,为水产品质量安全的管理监督提供科学依据。运用乙酰丙酮分光光度法,先后对12种314个淡水鱼类样品、19种356个海水鱼类样品、9种147个虾蟹类样品、5种137个贝类样品和4种59个头足类样品共计1013个鲜活水产样品中本底甲醛含量进行了测定。研究结果表明,多数鲜活水产品中甲醛的本底含量处于低端水平;在调查的49个水产品样品种类中,龙头鱼、鳕、中国枪乌贼、口虾蛄、梭子蟹等种类甲醛本底含量较高;淡水鱼类样品中的罗非鱼甲醛含量要显著高于其它种类的淡水鱼类(P<0.05);不同类型的水产品之间甲醛含量也存在一定差异(P<0.05),具体表现为海水鱼类样品中甲醛含量最高,其次为头足类样品、甲壳类样品和贝类样品,淡水鱼类样品中甲醛含量最低。
In order to provide scientific basis for the management and supervision of fishery products＇safety,the background concentrations of formaldehyde in various fresh fishery products were investigated.The concentration of formaldehyde in 1013 fishery product samples,which including 314 samples of 12 species of freshwater fishes,356 samples of 19 species of marine fishes,147 samples of 9 species of crustaceans,137 samples of 5 species of shellfish and 59 samples of 4 species of cephalopods,were determined by acetylacetone spectrophotometric method.The results showed that most fresh fishery product samples have low formaldehyde contentration.In the survey of 49 species,bombay duck（Hacpodon neheceus）,cod（Cadous macrocephalus,Theragra chalcogramma and Miciomesistius poutassou）,squid（Loligo chinensis）,squill（Oratosquilla）and swimming crab（Portunus trituberculatus and Portunus pelagicus）had higher levels of formaldehyde in the background.While formaldehyde content in tilapia seemed to be significantly higher than other freshwater fish species（P 0.05）.Significant differences on types showed that the formaldehyde conerntration in marine fish samples were great,followed by samples of cephalopods,crustaceans and shellfish,however,samples of freshwater fish was in the lowest formaldehyde content（P 0.05）.
