摘要：

为估计渤海湾地区生鲜海产品甲醛本底值提供科学依据。通过测定渤海湾部分地区常见生鲜海产品中的甲醛含量，在秦皇岛港、唐山港、黄骅港三地港口随机采集渔船上的海产品4类23种共222份，其中鱼类7种，甲壳类6种，贝类8种，软体动物类2种。利用乙酰丙酮分光光度法测定甲醛含量。结果表明：海产品中均有一定含量的甲醛，均值为1.798 mg/kg。鱼类甲醛本底含量平均值为1.284 mg/kg，甲壳类甲醛本底含量平均值为2.950 mg/kg，贝类甲醛本底含量平均值为1.387 mg/kg，软体动物类的甲醛本底含量平均值为0.845mg/kg。海产品有一定的甲醛本底值,本研究为制定海产品中甲醛安全限量标准及食品卫生执法提供科学依据。

Abstract:

This paper was to find out the background concentration of formaldehyde in fresh seafood through determining the concentration of formaldehyde in usual fresh seafood in Bohai Bay region. [Methods] 222 samples of 4 kinds and 23 species were collected randomly from fishing vessels at Qinhuangdao Port, Tangshan Port and Huanghua Port in Bohai Bay Region from April 2011 to October 2011, which contained 7 kinds of fish, 6 kinds of crustacea, 8 kinds of shellfish and 2 kinds of mollusk. This paper was used acetylacetone spectrophotometry to determine the concentration of formaldehyde. The results showed that there was some content of formaldehyde in all fresh seafood, and the average value was 1.798 mg/kg. The background concentration of formaldehyde in fish was 1.284 mg/kg. The background concentration of formaldehyde in crustacea was 2.950 mg/kg. The background concentration of formaldehyde in shellfish was 1.387 mg/kg. The background concentration of formaldehyde in mollusk was 0.845 mg/kg. There was some background concentration of formaldehyde in fresh seafood. This investigation was to provide sciscientific basis for formulating the limit standard for formaldehyde concentration in seafood and enforcing the law of food hygiene.
