In this study we evaluated the effects of gamma irradiation at doses of 0.0, 0.5, 2.0 and 4.0 kGy and
frozen storage as a combination process on improvement of turkey breast meat shelf life. The samples
were stored at 18 1C and were undergone microbial, chemical and sensory evaluation at 2-month
intervals. However, 4 kGy dose reduced the counts of mesophilic bacteria and coliform by more than 5
log units, while Salmonella was not detected. Irradiation of samples signi cantly increased peroxide
value but had no signi cant effect on total volatile nitrogen contents, while storage signi cantly
increased the peroxide value and total volatile nitrogen.
