摘要:

以新鲜猪肉为原料,研究食盐、复合香辛料、料酒添加量作为正交试验因素的生鲜调理猪肉在MAP包装条件下的感官卫生指标的变化。结果表明:生鲜猪肉调理后菌落总数、pH值有显著下降(P<0.05),在4℃贮藏过程中,这两个指标均逐渐上升,至5d时,达到国家二级生鲜猪肉标准水平。红度值(a*值)逐渐下降,货架期(5d)内仍在可接受范围内。食盐与复合香辛料以及料酒含量对菌落总数的影响有显著交互作用(P<0.01),综合菌落总数和pH值为目标函数的回归优化结果,最终得出配方为食盐1.8%、复合香辛料1.5%、料酒8%。

Abstract:

This study aimed to investigate the effect of three marination ingredients including salt, composite spices and cooking
wine on the sensory and microbial quality of modified atmosphere packaged (MAP) fresh pork meat during storage at 4 ℃. Results
showed that fresh pork exhibited a significant reduction in total bacterial count and pH after marination (P < 0.05). During storage at
4 ℃, gradual increases were observed for these two indicators and on the 5th day, they met the national standards for level 2 of fresh
pork. Red value gradually decreased but it was still acceptable within the shelf life (5 days). There were significant interactions among
salt, compound spices and cooking wine concentration on total bacterial count (P < 0.01). According to comprehensive regression
analysis of pH and total bacterial count, the optimal maridate consisted of salt 1.8%, composite spices 1.5% and cooking wine 8%.
