Abstract

Gamma irradiation with 5 KGY was suggested to increase the stability of ready to eat fish products during stargae . Bob Fish was pre­pared by frying, roasting after bran coating, roasting on spit using char­coal or cold smking. Irradiation caused negligible changes in the organo­leptic properties, and increased the shelf life at 4 °C, from 7 to 20 days, from 12 to 15 days , from 12 to 52 days and from 2 to 6 months for fried , spit roasted, bran coated then roasted and cold smoked samples respectively. Spoilage occurred when values of T. V. N., T. M. A., A. N. and T. B. A. were 25.00 - 33.46 mg/100 g, 5.82 -8.46 mg/100, 308­386 mg /100 g and 1.01 -1.37, respectively.
