Description
The effect of gamma irradiation on the quality of kareash cheese was evaluated. Egyptian kareash cheese were subjected to gamma irradiation at different safety doses beginning from 1 kGy to a maximum of 5 kGy . The physico-chemical composition as well as microbiological quality of kareash cheese samples was monitored before and after irradiation. Soluble nitrogen, salt as well as pH values were higher in cheese samples before irradiation in comparison with the irradiated groups. Irradiation reduced population of bacteria i.e. total colony count, Total yeast and mold count, aerobic spore former count, Coliform count, total Enterobacteriacae count and the effect was more pronounced at the highest dose (5 kGy). It could be concluded that increasing the dose of irradiation up to 5 kGy had high reduction percentages for bacterial count with no effect on either sensory or chemical characteristics. Our results suggest that kareash cheese manufacturer could use gamma irradiation to improve the safety of their product. (author)
