A method was developed for the separation and determination of ten preservatives including propionic acid (PA),sorbic acid (SA),benzoic acid(BA),dehydroacetic acid (DHA),methyl paraben (MP),ethyl paraben(EP),propyl paraben (PP),butyl paraben (BP),isopropyl paraben (IPP)and isobutyl paraben (IBP)in feeds within 7 min by gas chro-matography using DB-5MS capillary column with temperature programmed technology.The results showed that:the correla-tion coefficient of the ten preservatives was more than 0.9989,the average recoveries were between 81.5% and 90.0%, the detection limits were between 0.1 μg/mL and 5 μg/mL,the relative standard deviation (RSD) was less than 5.0%.
