魚肝油中維生素D3 、香精香料及重金屬的檢測(cè)方法研究
[Abstract]:Cod liver oil is a fatty substance extracted from the liver of fish such as cod and shark. It is rich in vitamins and unsaturated fatty acids. The quality of cod liver oil was evaluated in three aspects: the traditional method for the detection of cod liver oil vitamin D3 was complicated. A super high efficiency phase chromatography was established to detect the content of cod liver oil vitamin D 3. The samples were extracted directly by hexane. Waters 1-AA column was used with mobile phase of 80%CO2 and 20% methanol. The detection limit of the method was 1.2 mg/kg; and the quantitative limit was 5 mg/kg.. The average recoveries of vitamin D _ 3 were 89.1 and the relative standard deviation (RSDs) was 0.3-3.2. The method was simple and sensitive, and could be used for rapid determination of vitamins in cod liver oil. In order to cover up the fishy smell of cod liver oil, however, some flavours are harmful to human body. In this paper, gas chromatography-tandem mass spectrometry (GC-MS/MS) was used to establish a method for the detection of eight forbidden flavors in cod liver oil for the first time. Ultrasonic assisted extraction of n-hexane from samples was carried out and three common purification methods were investigated: improved QuEChERS method for solid phase extraction (SPE), membrane filtration purification method, and final determination of membrane filtration purification method. The method is sensitive, efficient and suitable for the determination of flavoring in cod liver oil. The heavy metal elements of Cu,As,Cd,Pb in cod liver oil were determined by inductively coupled plasma mass spectrometry (ICP-MS). The samples were treated with nitric acid and hydrogen peroxide. After microwave digestion, the contents of Cu,As,Cd,Pb were determined by ICP-MS. The ICP-MS method for the determination of heavy metals in cod liver oil samples was established for the first time. The method is sensitive and suitable for the determination of heavy metals in cod liver oil samples.
