Gamma irradiation is highly effective in inactivating microorganisms in various foods and it offers a safe alternative method of food pasteurization. γ-Irradiation at various doses has no significant effect on the titratable acidity, pH, total soluble solids, sugars and organic acid contents of mango juice samples obtained from different cultivators. Irradiation at doses of 1kGy and above inhibited the growth of bacteria, yeasts and moulds in all the juice samples. The colour indices showed significant statistical differences among the control and irradiated juice samples. This study provides information on the possibility of application of irradiation for improving shelf-life and quality of mango juice.
