초록

This study was conducted to evaluate changes in the flavor patterns of gamma irradiated raw oyster and oyster cooking drip using an electronic nose, which consisted of a GC equipped with a surface acoustic wave sensor. The raw oyster was irradiated with 1, 2, 3, 4 and 5kGy, while the oyster cooking drip was irradiated with 10 and 50kGy. In the case of raw oyster, the intensities of peaks at retention times (RT) of 2.1 s and 6.8 s were increased, but the peak at a RT of 9.0 s was decreased depending on irradiation dose. In the case of oyster cooking drip, the intensities of peaks at RT 2.5 s and RT 4.1 s increased linearly, but at the peak at RT 5.1 s decreased as the irradiation dose increased. The total amount of flavor components measured in raw oyster increased, while that of oyster cooking drip decreased in response to irradiation.
