摘要 【目的]介绍微波真空包装的组成、工作原理及结构,证明应用微波真空包装技术的优越性。[方法]以酱牛肉为材料,试验设3种
杀菌方式:微波真空包装 (2450MHz,有效杀菌时间180S);真空包装后高温杀菌(121oC、20min);真空包装后沸水杀茵(20min)。依据
感官品质评价、理化检验、食品物性学检验、微生物学检验等检测方法,对3种方式处理的酱牛肉,在品质及理化指标进行比较。[结果]
微波真空包装技术在杀菌的同时进行真空包装,避免了真空包装2次加热杀菌处理的不 良效果,且微波真空包装的酱牛肉各项指标均
优于其他2种包装处理方式,同时降低 了工艺成本,提高了生产效率。[结论]该研究为微波真空包装技术的在食品工业中的应用提供
了参考。
