Not AvailableFresh dried and old dried sangari (Prosopis cineraria) were treated with 0, 2.5, 5.0, and 7.0 kGy of irradiation and subsequently stored at ambient temperatures. Proximate values and total bacterial counts were evaluated immediately after irradiation and at regular intervals of 1 month during 3 months of storage. No significant changes were found in moisture, fat, protein, ash and fiber contents. Total sugar content was increased in both control and irradiated samples possibly due to conversion of starch into sugars. Irradiation treatment reduces total bacterial counts of dried samples of both fresh and old dried sangari. However, a dose of 5.0 kGy completely decontaminated both sangari and there was no microbial growth in 5.0 kGy irradiated samples during the storage period. Irradiation at 5.0 kGy was enough to extend the shelf-life of dried sangari up to 3 months without any significant change in the nutritional qualities.Not Availabl

Not AvailableFresh dried and old (6–12 months) dried kachri (Cucumis callosus) were treated with 0, 2.5, 5 and 7 kGy of gamma radiation in a cobalt 60 gamma cell (GC-1200). The irradiated samples of kachri were stored at room temperature (28±2 °C). Total bacterial count and nutrient composition were evaluated immediately after irradiation and at regular intervals of 1 month during 3 months of storage. Results indicated that gamma radiation reduced the total bacterial counts of dried samples of both fresh and old dried kachri. Dose of 5.0 kGy was sufficient to eliminate total bacterial count and there was no microbial growth in 5.0 kGy irradiated samples during the storage period. No significant differences were observed in the proximate composition of both types of kachri at all irradiation doses. It was concluded that irradiation treatments of kachri improves keeping quality of both freshly dried and old dried Kachri.Not Availabl
