摘要: 对真空包装后的酱牛肉采用低温水浴杀菌和微波两种方式进行二次杀菌处理,结果表明,低温水浴杀菌效果优于微波杀菌。低温水浴杀菌能显著降低酱牛肉贮藏期间的菌落总数、TVB-N值、TBA值,减少酱牛肉贮藏期间腐败,抑制贮藏期间脂肪氧化的产生,延长酱牛肉货架期。综合考虑,实践上选用90~95℃、30min的二次杀菌处理。

关键词: 酱牛肉, 低温杀菌, 货架期

Abstract: Spiced beef was treated with two-stage sterilization of low temperature water bath and microwave respectively after being vacuum packaged. The results indicated that low temperature water bathing sterilization is more effective than microwave sterilization. There are obvious decreases of total bacterial counts,TVB-N value,TBA value and lipid oxidation of the spiced beef with low temperature water bathing sterilization during storage. And thus its shelf life is extended. In terms of comprehen-sive consideration,low temperature water bathing sterilization(at 90 ~95 ℃ for 30 min)is more suitable for prolonging shelf life of spiced beef in practice.

Key words: spiced beef, low temperature water bathing sterilization, shelf life
