Abstract

The objective of the intercomparison described was to examine the potential of using volatile hydrocarbons, including 2-dodecylcyclobutanone to detect freshly irradiated and stored chicken meat. Samples of chicken meat were irradiated at approximately 0.5, 3.0 and 5.0 kGy. Each laboratory analysed 15 samples one month after irradiation and a further 15 samples after storage for 6 months at -20 C. A total of 239 samples were analysed for the hydrocarbons while 134 samples were examined for 2-dodecylcyclobutanone. All samples given approximately 3.0 and 5.0 kGy were correctly identified using 2-dodecylcyclobutanone while 94 % of samples given about 0.5 kGy were correctly identified. There were no false positives. As for the hydrocarbons, the concentrations of 2-dodecylcyclobutanone varied from laboratory to laboratory. Nevertheless, 99 % of samples were correctly identified using 2-dodecylcyclobutanone.
