The food irradiation marker, 2‐dodecylcyclobutanone (2‐DCB), assayed by SPME provides a fast and simple method to estimate the irradiation history of fat‐containing food products. The SPME conditions were optimized to maximize the extraction of 2‐DCB from chicken jerky treats (CJT) irradiated at low (5 kGy) and high (50 kGy) doses. The extracted 2‐DCB was measured using GC‐MS in selected ion mode...
Abstract: The amount of irradiated beef in the U.S. market is growing, and a reliable, rapid method is needed to detect irradiated beef and quantify the irradiation dose. The official analytical method (BS EN 1785 2003) that has been adopted by the European Union is time consuming. The objective of this study was to develop a rapid method for the analysis of 2‐dodecylcyclobutanone (2‐DCB) in irradiated...
