Abstract In cold smoked species of genus Coregonus, identified by molecular genetic analysis, contents of fatty acids and heavy metals and arsenic were measured. The highest content of sum of long-chain polyunsaturated fatty acids of omega-3 family (LC-PUFA), namely eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids, 6.53 ± 0.78 mg g−1 wet weight, was characteristic of tugun Coregonus tugun. This is the first quantitative estimation (mg LC-PUFA per g of product) of the nutritive value of smoked fish. Thus, to obtain a daily personal doze of EPA + DHA of 1 g, recommended for prevention of cardiovascular diseases, one needs to consume 153 g of the smoked tugun. Metals contents did not exceed standards for fish meat except Pb in least cisco Coregonus sardinella. Accordingly, values of hazard quotients, which estimate benefit-risk ratio of fish intake, indicate that most of the smoked fish species are safe product for human nutrition, except least cisco regarding Pb content.

西伯利亚七种熏鱼中omega-3多不饱和脂肪酸和重金属的益处-风险分析

摘要 通过分子遗传学分析鉴定了冷熏种Coregonus 中脂肪酸、重金属和砷的含量。omega-3 家族长链多不饱和脂肪酸 (LC-PUFA) 的最高含量，即二十碳五烯 (EPA) 和二十二碳六烯 (DHA) 脂肪酸，6.53 ± 0.78 mg g-1 湿重，是 tugun 的特征Coregonus tugun。这是对熏鱼营养价值的首次定量估计（每克产品中含有 LC-PUFA 毫克数）。因此，要获得 1 克推荐用于预防心血管疾病的 EPA + DHA 个人每日瞌睡，一个人需要消耗 153 克烟熏 tugun。至少cisco Coregonus sardinella 中的Pb 除外，金属含量没有超过鱼肉的标准。因此，危险商的值，
