Abstract:
A rapid method for authenticity detection of grapeseed oil was proposed based on Ion Mobility Spectrometry ( IMS) . After optimization, the inlet temperature was set at 170 ℃, drift tube temperature was set at 60 ℃. In this method, the oil sample was diluted in hexane (50-fold, V/V) and then directly analyzed in IMS. The detection time was 20 s. To establish an adulteration detection model, recursive Support Vector Machine ( R-SVM) was applied to classifying pure and adulterated grape seed oils. The result of 10-fold cross validation showed that the accuracy of discrimination was up to 91 . 2%. The results in study indicate that IMS method is a new, fast and convenient technique for the adulteration detection of edible oil.
