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.展开更多

The results showed that radiation dose of 1.0 kGy completely, inhibited insect infestation. Low dose radiation (0.25kGy) plus 20℃ and vacuum extended the storage life for 6 and 12 months in dry nuts and fruits respectively without affecting nutritional quality except ascorbic acid. Packaging in opaque pouches under vacuum proved better than other treatments in maintaining nutritional and sensoric quality.展开更多
