The authors of this study (open access) have used gas chromatography with mass spectrometry in selected ion monitoring mode (GC/MS-SIM) to create a database that summarizes the occurrence and semi-quantitative levels of 150 sterols with 27–32 carbon atoms and 0–4 double bonds in 66 different vegetable oils and eight other matrices. They believe that this is the first time that such a comprehensive sterol database has been collated.
The paper includes a pdf Appendix file that lists all of the oil varieties and sterol markers in detail. This is an open-access resource for any analyst wanting to use sterols as varietal markers for edible oil identification.
The reference has been added to FAN’s searchable list of food authenticity databases.
