Abstract

The effects of gamma irradiation on microbial load total aflatoxins and phytoconstituents content of Trigonella foenumgraecum have been studied Gamma irradiation at a dose of 25 kGy resulted in 2 log reduction of the total aerobic microbial count A complete sterilization was however observed at 10 kGy The total aflatoxin level decreased gradually with increase in gamma irradiation dose as compared to its unirradiated counterparts whereas the high performance liquid chromatography HPLC profile showed no change in the levels of phytochemicals up to the gamma irradiation dose of 10 kGy HPLC profiles however differed in peak areas and retention times of the components These results suggest that gamma irradiation at a dose of 50 kGy was very effective for microbial decontamination because it did not adversely affect the active components of T foenumgraecum
