| 摘 要： | 通过对56种海水鱼共计105个样品，16种淡水鱼共计19个样品的甲醛本底含量研究。结果发现，食用鱼类的甲醛本底含量不同且差异较大，海水活鱼与海水冷冻鱼的甲醛含量均显著高于淡水活鱼与淡水冷冻鱼（P〈0．01）；海水鱼中龙头鱼和鳕鱼类样品甲醛本底含量较高；大部分淡水鱼未检出甲醛；同一品种不同存活状态的鱼，其甲醛含量也不同，活体鱼中甲醛含量最低，冰鲜样品中甲醛含量最高，冷冻样品随着冻藏时间的延长甲醛含量呈现上升趋势。

| Abstract: | The intrinsic formaldehyde in 56 species of marine fish including 105 samples and 16 species of freshwater fish including 19 samples was studied. The results showed that the content of intrinsic formaldehyde was different in edible fish,and that the formaldehyde content was evidently higher in live and frozen marine fish than that in the freshwater fish (P<0.01).The intrinsic formaldehyde contents in Hacpodon neheceus and Cadous macrocephalus were higher especially,while no formaldehyde was detected in most freshwater fish. Fish in different existent states had different intrinsic formaldehyde,the live fish lowest,while the ice-stored fish highest. And the concentration of intrinsic formaldehyde in the frozen fish samples was increased as the storage time increased. |
