Abstract: The effect of chilled pork treated with or without preservation solution, irradiation dose(1,2 and 3kGy)on the physicochemical and sensory characteristics of vacuum-packaged chilled pork stored at (4±1℃)for 21days were studied, in order to determine the best method of irradiation to extend shelf life of chilled pork. The result show: The chilled pork color is stable in the storage-life when the X-ray was 2kGy. The best method that can extremely extend shelf life of chilled pork is that the sample are treated with preservation solution, vacuum-package, 2.0kGy irradiation and refrigeration.

Key words: chilled pork, irradiation by gamma ray, physicochemical characteristics, sensory characteristics, dose
