SYNTHESIS, CHARACTERIZATION, AND POTENTIAL USE OF 2-DODECYLCYCLOBUTANONE AS A MARKER FOR IRRADIATED CHICKEN

The synthesis and characterization of 2-dodecylcyclobutanone is described. Solvent extraction techniques for the isolation of this compound from irradiated minced chicken meat and its detection by selected ion monitoring are outlined. The compound was not detected in either raw or cooked nonirradiated minced chicken meat by the methods used, but its presence was confirmed in the irradiated samples. 2-Dodecyclobutanone was detectable for 20 days postirradiation. The dose (4.7 kGy) of irradiation applied was below the recommended upper limit for food (10 kGy), and this compound may have potential as a marker for irradiated chicken meat and for other foods containing lipid.
