Researchers from the Swedish University of Agricultural Sciences (Uppsala, Sweden) and the University of Tabriz (Tabriz, Iran) developed a solid-phase extraction method to separate sterol oxidation products in food lipids for analysis by gas chromatography (GC) and GC–mass spectrometry. The method used 1 g of silica as the extraction medium. Both transesterified and cold saponified oil samples could be analyzed using the method. The method provided a high recovery of the sterol oxidation products from rapeseed oil and was tested and applied to various vegetable oils and hazelnut oil.
