摘要: 本实验通过研制了一种新型纳米包装材料,与普通包装材料相比,透氧量降低2.1%,透湿量降低28.0%。用纳米包装材料和普通聚乙烯材料包装酱牛肉,分别对其理化指标、感官指标和微生物指标进行分析。结果表明,在酱牛肉保鲜中,纳米材料能有效抑制酱牛肉中细菌的生长繁殖,降低挥发性盐基氮的产生,并延长了酱牛肉的保质期,很好的保存了产品的色泽和风味。

Abstract: A new fashioned nano-packing was developed for the preservation of food.The O2 and RH transmission rate of the packing decreased 2.1% and 28% compared with normal packing.Sauce beef was packed with nano-packing at room temperature for 28 days,Sensory quality,physical and chemical quality and micro indexes were analyzed to investigate the effects of nano-packing on preservation quality of sauce beef.The results showed that nano-packing could significantly inhibit the increasing of bacteria and volatile base nitrogen(VBN) of sauced beef compared with normal packing.Meanwhile,nano-packing could expand the shelf life of sauce beef,and maintain its colour and flavor.

Key words: nano-packing, sauce beef, preservation quality
