| Abstract: | The detection methods for glycerin, propylene glycol and diethylene glycol in pet food by gas chromatography-flame ionization detection（GC-FID） were studied in this paper. We examined the effects of extraction reagent, extraction method and extraction time on test results. The detection method for glycerin, propylene glycol and diethylene glycol was established. The detection limit was 0.05,0.01 and 0.02 g/kg separately. The experimental results show that this method is convenient, rapid, accurate and economical. |
