Wheat grain was exposed to gamma ionising irradiation at selected doses between 0.05-10 kGy and microwave radiation from 45 to 180 sec. The sensory evaluation of a grain odour proved that both applied treatments, gamma and microwave irradiation, did not cause significant changes in the grain odour in comparison to control samples of grain with the exclusion of maximum irradiation dose 10 kGy, and maximum microwave heating time 180 sec. The results obtained after measurement of the grain reflected-light showed that gamma 60Co irradiation did not cause any changes in grain colour. The grain after microwave heating at 90, 120, 180 sec was characterised by significantly higher lightness (L*) value. The total colour difference (E) between microwave irradiated samples and the control ones was increasing gradually, with the increase in temperature.
