Present study was conducted to examine the effect of gamma radiation on nutritional quality and shelf life extension of peaches. Peach “Swat local variety No. 4” samples were radiated with Cobalt-60 Doses 0.25, 0.5 and 0.75 kGy and different parameters such as % age of weight loss, moisture loss, ash content, crude fiber, crude fat, total soluble solids (TSS), pH and titratable acidity were studied. It was found that 0.75 kGy was an effective dose to increase the shelf life of peaches to three weeks at refrigerated temperature. It was expected that this technique affect’s the Pakistan economy in a positive sense. Moreover, it could help to overcome quarantine barriers by enhancing lifespan of peaches.
