【摘要】 <正>氯丙醇(chloropropanols,CPDs是丙三醇结构上的羟基被氯原子取代的一类化合物,包括3-氯-1,2-氯丙醇(3-MCPD)、2-氯-1,2-氯丙醇(2-MCPD)、1,3-二氯-2-丙醇(1,3-DCP)。食品添加剂和污染物联合专家委员会对CPDs进行了评价,发现3-MCPD危害广泛,可损害人体的肝、肾、神经系统等器官,因此制定3-MCPD的暂定每日最大耐受量(TDI)为2μg/kg。
【Abstract】 A new method for determination of 3-MCPD in powder condiments was established by GC - MS method using 1,4-butanediol as an internal standard.Samples were ultrasonically extracted by ethyl acetate, and cleaned up by dispersive solid-phase extraction(d-SPE) using octadecane sorbent(C18).Then the extract was derivatized with HFBI and detected by GC - MS.The detection limitation was 1.0μg/kg,and spiked recoveries ranged from 97%-102%with RSD of 2.1%-4.1%.
