2-alkylcyclobutanones have been successfully used as chemical markers for irradiated foods. Unfortunately, most sample preparation, and isolation methods for these markers from their food matrices involve a long and very tedious clean-up regimen prior to analysis. A simple and rapid method for the isolation of these markers using carbon dioxide as a supercritical fluid is described for beef and chicken samples irradiated up to 8 kGy. Significant levels of both 2-dodecylcyclobutanone (2-DCB) and 2-tetradecylcyclobutanone (2-TCB) were extracted from all irradiated samples using carbon dioxide as a supercritical fluid, the method is proposed as an alternative to the florisil chromatography method currently in use.
