method for analysis of the edible oil with crab taste by gas chromatography has been developed. The sample was directly introduced on a Silicone XE-60 capillary column . 25m×0. 25mm×0. 5μm, with a one-ramp temperature programming (hold 10min at 80℃, increased upto 180℃ at 20℃/min and then hold 20min) and detected by FID. For the component identification mass spectrometry was used. The above condition was chosen after in comparison with a PEG-20M column. 相似文献
