摘要: 采用基质固相分散萃取法(MSPD)进行样品的净化,以稳定性同位素稀释技术结合气相-质谱法(GC-MS)的内标法定量测定氯丙醇,初步调查了我国市售水解蛋白(HVP)氯丙醇的污染水平。发现酸水解HVP产品氯丙醇污染严重,氯丙醇的典型代表3-氯-1,2-丙二醇(3-MCPD)的几何均数达到6.04mg/kg(以液体计),70%的样品3-MCPD含量超过10mg/kg。

Abstract: A survey was carried out to investigate chloropropanols contamination of the selected hydrolyzed vegetable protein (HVP)products in the retailer outlets in China with the stable isotope dilution technique coupled with gas chromatography-mass spectrometer. Results showed that levels of 3-monochloropropane-1,2-diol (3-MCPD) of HVP products are relatively high with a geometrical mean of 6.04mg/kg in liquid. Seventy percent of the products surveyed contained levels of 3-MCPD above 10mg/kg.

Key words: hydrolyzed vegetable proteins (HVP), 3-monochloropropane-1, 2-diol, contamination
