  γ-Irradiation is highly effective in inactivating microorganisms and enzymes activity in various foods and it offers a safe alternative method of food decontamination and maintaining quality. Water melon juice was exposed to γ- irradiation of 1, 3 and 5 kGy at room temperature (25 ± 1°C). With regard to colorimetric parameters the fresh water melon juice was lower than the irradiated samples. There was an improvement in the Hunter color value in irradiated water melon juice compared with fresh samples. The ascorbic acid, other antioxidants measured (DPPH, β-carotene asays, total phenols, flavonoids and antioxidant capacity) showed enhancement on expsoure to γ-irradiation. Microbial studies showed reduction in total bacterial counts in irradiated juice at 5 kGy. γ-irradiation improves microbial decontamination and antioxidant activity as well as .. View More»
