Gamma irradiation was used to reduce the N-nitrosamines in emulsion-type cooked pork sausage during storage at 4$^{\circ}C$. The sausage without ascorbate to maximize the N-nitrosamine formation and the sausage with 200 ppm sodium ascorbate were prepared, respectively. The sausages were aerobically or vacuum packaged and irradiated at 0, 5, 10 and 20 kGy. A statistically significant difference was not shown in N-nitrosodimethylamine (NDMA) and N-nitrosopyrrelidine (NPYR) levels in the sausage prepared with sodium ascorbate at 0 week, while the NDMA and NPYR reduction was observed after 4 weeks storage. The NDMA level in the sausage without sodium ascorbate and irradiated at 10 kGy or above reduced in aerobic packaging, while a dose of 20 key was needed in vacuum packaging. The N-nitroscpyrrolidine reduction was shown at 20 and 30 kGy-irradiation. The results indicated that gamma irradiation was effective to reduce N-nitrosamines level in sausage during storage.
