摘要: 对真空包装后的烧鸡采用低温(85℃、30min;90℃、30min;95℃、30min)和微波(900W、2min)两种方式进行二次杀菌处理,结果表明,低温水浴杀菌效果明显优于微波杀菌。低温水浴杀菌能显著降低烧鸡贮藏期间的菌落总数、TVB-N值、TBA值,减少烧鸡贮藏期间腐败,抑制贮藏期间脂肪氧化的产生,延长烧鸡保质期,但水浴杀菌对贮藏期间烧鸡的pH影响不大。综合考虑,实践上应选用85~90℃、30min的二次杀菌处理。

Abstract: The roasted chicken were treated with two-stage sterilization of low temperature-heat (85 ℃, 30 min; 90 ℃, 30 min; 95 ℃, 30 min) and microwave (900 W, 2 min) sterilization respectively after vacuum packaged. The results indicateed that the low temperature-heat sterilization is more effective than microwave sterilization. There is an obvious inhibition of the total viable counts, TVB-N value, TBA value and lipid oxidation of the roasted chicken with low temperature-heat sterilization during storage. The shelf life is extended, but there is no obvious variation of pH value of the roast chicken treated with two-stage sterilization of low temperature-heat during storage. For comprehensive consideration to selection of the sterilization condition, two-stage sterilization of low temperature-heat (85~90 ℃, 30 min) is suitable for roasted chicken.

Key words: roasted chicken, low temperature-heat sterilization, shelf life
