国产与进口鱼油胶囊质量安全指标比较研究

Comparative study on quality and safety indexes of domestic and imported fish oil capsules.

以市售国产与进口鱼油胶囊为研究对象,通过对标签、感官、EPA和DHA含量、过氧化值和酸价、重金属等指标的检验分析,发现国产与进口鱼油胶囊均存在标签不规范、EPA和DHA的实际含量低于标示值、过氧化值和酸价超标等问题。进口鱼油中EPA、DHA、过氧化值和酸价的合格率分别为53.3%、60.0%、62.5%和77.5%,国产鱼油分别为77.8%、80.0%、90.0%和100%;研究中也分析了进口和国产鱼油胶囊中的抗氧化剂和金属元素含量水平,结果显示均合格。综合以上指标比较分析,国产鱼油较于进口鱼油,特征组分EPA和DHA实际含量的合格率更高,氧化水平更低,品质更优。

Through inspection and analysis of the label,sensory,EPA and DHA content,peroxide value and acid value,heavy metals and other indicators,it is found that domestic and imported fish oil capsules have problems such as nonstandard label,the actual content of EPA and DHA is lower than the marked value,peroxide value and acid value exceed the standard.The qualified rates of EPA,DHA,peroxide value and acid value in imported fish oil are 53.3%,60.0%,62.5%and 77.5%,respectively;while those in domestic fish oil are 77.8%,80.0%,90%and 100%,respectively.The contents of antioxidants and metal elements in imported and domestic fish oil capsules are all qualified.Compared with imported fish oil,domestic fish oil has higher qualified rate of EPA and DHA,lower oxidation level and better quality.
