摘  要:
本文建立了检测膨化食品中3-氯-1,2-丙二醇和1,3-二氯-2-丙醇含量的方法。采用乙醚索氏提取、甲醇净化,再经N,O-双(三甲基硅烷)三氟乙酰胺(BSTFA)衍生,毛细管气相色谱法分离,FID作检测器。方法检出限为0.01mg/kg,回收率85%~5%。

摘  要:
An improved method for determination of 3-chloro-1,2- propanediol and 1,3-dichloro-2- propanol in expanded foodproducts was presented. Chloropropanols were extracted with diethyl ether in reflux extractor, then purified with methanol incentrifuge tube. The identity of N,O-bis(trimethylsily)trifluoroacetamide derivatives was confirmed by capillary gas chromatog-raphy with flame ionization detection. The detection limit of the method was 0.01μg/g . Recoveries of chloropropanols rangedfrom 85 to 95% .
