Almond, groundnut, pinenut and walnut, were radiated (0.25 kGy) after packing in coloured and clear polyethylene bags (0.04mm) and subsequently stored for 24 weeks at room (16-36℃) and low temperatures (10-20℃). The effect of these treatments on insect infestation and quality was studied. It was observed that radiation (0.25 kGy) treatment in combination with low temperature (10-20℃) completely checked the insect infestation of nuts during 24 weeks of storage. Peroxidation was higher in samples stored at room than at low temperature. Storage period had a marked adverse influence on sensory quality of nuts, however, samples kept at low temperature were comparatively rated higher.
