维生素C与异抗坏血酸钠对辐照盐水鹅品质的影响

Effect of vitamin C and sodium erythorbate on the quality of irradiated saltwater-stewed geese

摘要: 研究了添加维生素C与异抗坏血酸钠对盐水鹅真空包装制品经辐照处理后品质的影响。在盐水鹅中分别加入0.02%(w:w)的维生素C、异抗坏血酸钠两种抗氧化剂,作真空包装,经60Coγ射线以6kGy剂量辐照后,于25℃贮藏,对其Aw值、TBA值、POV值、酸价、TVBN含量进行序时检测。结果表明,相比对照组,盐水鹅的TBA值、POV值、酸价以及TVBN含量在辐照后28d内均显著降低(p<0.05),说明维生素C与异抗坏血酸钠在延缓脂肪氧化方面均效果明显;两者比较,异抗坏血酸钠的抗氧化效果优于维生素C。

Abstract: The effect of antioxidant vitamin C and sodium erythorbate on the quality of vacuum-packed irradiated saltwater-stewed geese was studied.Saltwater-stewed geese were added two antioxidants respectively, vitamin C (0.02%) and sodium erythorbate (0.02%) .The vacuum packaged samples were radiated by 6kGy 60Co-γ, then storaged at 25℃.The Aw value, TBA value, POV value, fatty acid value and TVBN content were analysed.The result showed that:TBA value, POV value, fatty acid value and TVBN content of saltwater-stewed geese decreased significantly (p<0.05) in contrast to the controls within 28d after irradiation, which meaned that each of two antioxidants could delay fat oxidation obviously, the antioxidant effect of sodium erythorbate was better than that of vitamin C.
