This study aimed to evaluate the effect of gamma irradiation on the nutritional composition, pH, and sensory quality of three vacuum-packaged eel products, namely smoked eel, unagi shirayaki, and unagi kabayaki. Gamma irradiation was carried out using a Cobalt-60 source at doses of 0 kGy, 1.5 kGy, 3 kGy, and 5 kGy. The evaluated parameters included moisture, protein, fat, ash, pH, color, and sensory attributes (appearance, odor, taste, and texture). The results indicated that gamma irradiation up to 5 kGy did not significantly affect the nutritional composition (moisture, protein, fat, and ash) or pH of the three eel products (p>0.05). However, higher irradiation doses tended to decrease panelists’ acceptance of sensory quality. Overall, the non-irradiated control (0 kGy) provided the best sensory quality, whereas irradiation at 3 kGy was considered the most feasible dose because it maintained nutritional composition and sensory quality at levels still acceptable to the panelists.
