Research Abstract

Irradiation of fat containing food generates a family of molecules, namely 2-alkylcyclobutanones (2-ACBs). Absence of 2-ACBs was confirmed in non-irradiated nutmeg and cashew nut using high-resolution gas chromatography-mass spectrometry. 2-ACBs were detected in irradiated soybeans and cashew nut at 1 kGy or greater and identified in the irradiated nutmeg at 5 kGy or greater. Radiation production yields of these 2-ACBs were 1.1 to 3.8 nmole/ mmole precursor fatty acids, same order as animal foods. 2-DCB and 2-dDCB was found in irradiated nutmeg even after 30 weeks of storage.
These results indicate the usefulness of 2-ACBs as maker compound for the identification of irradiation history of food from plant origins.
