摘要
目的了解我国市售海产品及其制品中甲醛的含量。方法采集全国8个省（市、自治区）的农贸市场和大中小超市销售的6种常见海产品及其制品（冰鲜鱿鱼、水发鱿鱼、鱿鱼丝、海虾、虾仁和烤鱼片）,共计530份,采用高效液相色谱（HPLC）法检测甲醛含量。结果 6种海产品及其制品均检出甲醛,总检出率为40.57%,含量范围为0.00~950.00 mg/kg。其甲醛平均含量由高到低分别为鱿鱼丝、水发鱿鱼、烤鱼片、冰鲜鱿鱼、虾仁和海虾,检出率分别为52.78%、57.45%、42.50%、49.61%、23.08%和12.24%。结论不同种类海产品及制品中甲醛含量不同且差别较大,可能与其本底水平、甲醛自身变化规律或者后期违法添加有关。总体来看,甲醛含量〉100 mg/kg,尤其是超过200 mg/kg的产品,应引起关注。
Objective To understand the formaldehyde content of common seafood and its products from different provinces in China. Methods 530 samples from 6 kinds of common seafood and its products（ ice fresh squid,waterswollen squid,shredded squid,shrimp,shelled shrimp and grilled fillet） were collected randomly from rural markets and city supermarkets in 8 provinces,and the samples were analyzed by the determination of formaldehyde content in food-high performance liquid chromatography（ HPLC） method. Results The formaldehyde was detected in all 6 kinds of seafood and their products. The detection rate was 40. 57%,and the range of content was 0. 00-950. 00 mg / kg. The average content of formaldehyde in descending order were shredded squid,water-swollen squid,grilled fillet,ice fresh squid,shelled shrimp and shrimp,and the detection rate were 52. 78%,57. 45%,42. 50%,57. 45%,23. 08% and 12. 24%,respectively. Conclusion Formaldehyde contents were different in different kinds of seafood and their products,that may rooted in the formaldehyde baseline,its changing rule or illegal adulteration. Overall,it should be concerned if the formaldehyde content was above 100 mg / kg,especially above 200 mg / kg.
