摘要:

为了改进酱牛肉的保鲜效果并延长其货架期,以真空包装为参照,探讨气调包装(5% O2+70% CO2+ 25% N2)对酱牛肉的保鲜效果。以细菌总数、硫代巴比妥酸反应物(TBARS)值、总挥发性盐基氮含量、pH值、 色差、风味为评价指标,比较酱牛肉真空和气调两种包装方式保鲜效果的差异。结果表明:在10 ℃贮藏18 d后,气 调包装组和真空包装对照组相比,其细菌总数降低2 个数量级,TBARS值降低了38.7%,挥发性盐基氮含量降低了 66.8%,且通过电子鼻主成分分析能将两种包装方式完全分开。表明气调包装更有利于酱牛肉的保鲜,可有效提高 其品质稳定性,并延长产品的货架期。

Abstract:

In order to preserve the quality of Chinese spiced beef and extend its shelf life, we compared the freshnessmaintaining
effects of modified atmosphere packaging (MAP, 5% O2 + 70% CO2 + 25% N2) and vacuum packing (VP) on
Chinese spiced beef, based on evaluation of the total bacterial count, thiobarbituric acid reactive substances (TBARS), total
volatile basic nitrogen (TVBN), pH, color and flavors. Results showed that when stored at 10 ℃ for 18 days, the total
bacterial count of the MAP group was reduced by two orders of magnitude, TBARS by 38.7% and TVBN by 66.8%
in comparison with the VP group. Principal component analysis (PCA) of electronic nose data showed that the two
packaging methods could be completely discriminated from each other. It can be concluded that the MAP is more
beneficial to the preservation of Chinese spiced beef, which is manifested by improving the quality and stability and
extending the shelf life of the product effectively.

Key words: Chinese spiced beef, preservation, modified atmosphere packaging, vacuum packaging, electronic nose
