表面解吸常压化学电离质谱法快速筛查劣质食用油
Rapid Screening of Inferior Quality Oils by Surface Desorption Atmospheric Pressure Chemical Ionization Mass Spectrometry
摘要
Abstract
By using a home-made surface desorption atmospheric pressure chemical ionization source,illicit cooking oils and normal edible oils were directly analyzed by mass spectrometry without any sample pretreatment.The MS data were further analyzed using principal component analysis（PCA）.The SDAPCI-MS fingerprints of illicit cooking oils were different from those of normal edible oils.With the application of PCA,illicit cooking oils were successfully differentiated from normal oils.The method developed here is attractive by showing the advantages of no need for sample pretreatment,high sensitivity and high analytical speed（1.0 min per sample）,and thus provides a fast and effective method to screen illicit cooking oils for the sake of food safety.关键词
