摘要: 研究真空包装冷却猪肉经保鲜液处理和未经过保鲜液处理,再分别经1kGy、2kGy和3kGy低剂量辐照后的理化和感官特性变化,进而确定最佳的辐照处理方式以延长冷却猪肉的货架期。结果表明:经过2kGy辐照的处理组,在贮藏的过程中,鲜红色泽保持相对的稳定。冷却猪肉经过保鲜液处理+2kGy剂量辐照+冷藏(4±1℃),可以有效的延长冷却猪肉的货架期。

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.
