摘要
调查了我国市售酱油氯丙醇的污染情况,样品来自2003年全国污染物监测网和2004年卫生部健康相关产品卫生抽检。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3-氯-1,2-丙二醇(3-MCPD)含量。对3-MCPD污染水平与某些因素的关系作了探讨,结果表明,国家免检、HACCP认证、包装形式等因素与3-MCPD水平有显著性相关关系(P<0.05),而QS认证、IS09000认证、推荐与监制、铁强化、生产工艺、质量等级和抽样场所等因素与3-MCPD水平的高低没有显著性关系(P>0.05),说明QS认证、IS09000认证、推荐与监制等措施对氯丙醇降低的作用不明显。此外,来自餐饮业酱油的氯丙醇污染相对较高,值得进一步关注。
A survey was carried out to investigate chloropropanols contamination of soy sauces manufacturing the retailers in China. Determination of 3-monochloropropane-1,2-diol（3-MCPD）was carried out by a method with the stable isotope dilution technique coupled with gas chromatography-mass spectrometer. Results show that some factors, such as HACCP certification, national free-inspection and package method have significant effects on levels of 3-MCPD in soy sauces（P 〈0.05）. Other factors such as Certification of ISO9000 quality management system and national Quality Safety Label, iron fortication, the agency＇ s recommendation, manufacturing process, quality class and sampling place of soy sauces do not have significant relationship with levels of 3-MCPD, indicating that the above factors do not significantly decrease the level of 3-MCPD in soy sauces.
