Abstract
Summary: Results are presented indicating a linear relationship between irradiation dose (10–60 kGy) and the quantity of 2‐dodecylcyclobutanone produced in irradiated frozen (‐46°C) chicken meat. 2‐Dodecylcyclobutanone was found in chicken meat sterilized (at ‐40°C) by gamma and electron beam irradiation 12 years previously and used for toxicity clearance. After freeze‐drying the irradiated chicken samples still contained 2‐dodecylcyclobutanone indicating that it was present in the diets tested. The compound was not detected in chicken meat sterilized by thermal processing 13 years ago. In addition, there was evidence that 2‐tetradecylcyclobutanone was also present in the irradiation sterilized samples.
