Abstract

The aim of the current study clarifies the effect of food irradiation as a preservation method on microbiological analysis and growth performance as well as genetic processes of Clariasgaripinus by estimating chromosomal aberration test in somatic cells and compare it with the effect of other food preservations such as preservation by freezing and preservation by thermal treatment on food. The results indicate that 25 and 35 kGy doses of gamma irradiation showed there were no growth in the total viable (mesophilic aerobic) plate counts and increased the shelf-life of samples compared with other preservation methods which used. There were no significant differences between irradiated and non-irradiated sample ingrowth Parameters. Higher dose of gamma irradiation was apparent that there were a significant (P < 0.05) decrease of the value of chromosomalaberrations.

Key words
