Abstract: 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% .

Key words: expanded food products, chloropropanols, gas chromatography
