In the present study the effect of electron beam irradiation on the quality characteristics of vacuum packaged headless vannamei stored at chilled condition was assessed by biochemical, microbial and sensory evaluation up to 28 days. The total volatile base nitrogen, peroxide value and thiobarbituric acid reactive substances
showed an increasing trend during storage.Non protein nitrogen content increased significantly in control
and 2.5 kGy treated sample .Texture analysis indicated that sample treated with 5.0, 7.5 and 10 kGy dose had
lower hardness and chewiness than 2.5 kGy treated and control. L value showed a decreased trend in all the samples during storage. Moreover, b and a value showed a gradual increase during storage. It was observed that aerobic plate count was lower in irradiated sample than control. Similar trend was also observed for
psychrophilic and pseudomonas count. There is significant reduction in lactobacillus count in the irradiated sample with respect to different doses during storage than control. Based on the microbial and sensory analysis control, 2.5 kGy irradiated sample had a shelf life up to 12th day, 15th day, respectively. However, 5kGy, 7.5 kGy and 10 kGy treated samples had a shelf life upto 23rd day.
