Abstract
When triglycerides or fatty acids are irradiated, some of the major stable products formed are hydrocarbons with one less carbon than the parent fatty acids. These hydrocarbons are formed as the result of the loss of CO 2 via various free radical reactions. A procedure has been developed utilizing capillary gas chromatography (GC) to monitor the formation of these hydrocarbons in gamma-irradiated frog legs. Since frog legs contain large amounts of palmitic, stearic, oleic, and linoleic acida, the formation of the hydrocarbons (pentadecane, heptadecane, 8-heptadecene, and 6,9-heptadecadiene, respectively) from the decarboxylation of these fatty acids was monitored. The yield of these hydrocarbons was found to be linear with applied dose. A sample from a lot of imported frog legs that were believed to have been irradiated was also analyzed. The results obtained from the GC determination of the hydrocarbons compared favorably with those obtained by using electron spin resonance to monitor the free radicals trapped in the frog leg bone after irradiation.
