Gamma irradiation with dose levels

Gamma irradiation with dose levels 1, 2 and 3 kGy decreased the iodine value. The iodine value was 86.74 g/100 g oil at an irradiation dose level of 3 kGy as compared with the control (87.85 I2 g/100 g oil). The decrease in iodine value upon irradiation could be attributed to some loss in the un-saturated fatty acids of pistachio oil by radiation and the formation of peroxide compounds. These results are in agreement with the results obtained by several investigators. Afify et al. (2013) reported that a marked decreased in iodine value was noticed for irradiated soy bean seeds.
