Screening Of Irradiated Tomatoes By Means Of An Electronic Nose

The use of an electronic nose for the investigation of gases produced by tomatoes is described. The tomatoes investigated were stressed by squeezing or irradiated. Altogether four classes were investigated; intact, stressed, irradiated and both irradiated and stressed. It was found that there were large differences in sensorsignal responses between stressed and unstressed tomatoes. Furthermore, the electronic nose could easily distinguish all four classes.
