The aim of this study was to evaluate the effect of three different strains of lactic acid bacteria (LAB) starter cultures: (KC-13100) (PP), (KCTC-21004) (LP1), and (KCTC-13093) (LP2) on the physicochemical and microbiological characteristics, and sensory quality of dry fermented sausages after 21 days of drying and ripening period. Treatments added with PP and LP2 strains showed a significant higher (p<0.05) LAB and total plat counts, and water activity (a) of all three treatments was below 0.85 after the completion of the ripening process. A significant variation (p<0.05) in pH values of treatments was exhibited due to the difference in acidification capacity of the LAB strains: LP2<PP<LP1. Treatments had significant difference (p<0.05) in the thiobarbituric acid reactive substances (TBARS) content, in the following order: LP1>PP>LP2. Substantial variations (p<0.05) in shear force values were detected amongst three batches (LP2>LP1>PP). In sensory attributes, PP treated samples had significantly higher (p<0.05) color and overall acceptability scores. The current findings proved how important the optimal assortment of starter culture. Inoculation with PP produced importantly beneficial effects on sensory quality improvement of dry fermented sausage.
本研究的目的是评估三种不同的乳酸菌(LAB)发酵剂菌株:(KC - 13100)(PP)、(KCTC - 21004)(LP1)和(KCTC - 13093)(LP2)在干燥和成熟21天后对干发酵香肠的理化和微生物特性以及感官品质的影响。添加PP和LP2菌株的处理组显示出显著更高(p<0.05)的乳酸菌和总平板计数,并且在成熟过程完成后,所有三种处理的水分活度(a)均低于0.85。由于乳酸菌菌株的酸化能力不同,处理组的pH值存在显著差异(p<0.05):LP2<PP<LP1。处理组在硫代巴比妥酸反应性物质(TBARS)含量上有显著差异(p<0.05),顺序如下:LP1>PP>LP2。在三个批次中检测到剪切力值有显著变化(p<0.05)(LP2>LP1>PP)。在感官属性方面,PP处理的样品在颜色和总体可接受性评分上显著更高(p<0.05)。目前的研究结果证明了发酵剂菌株最佳组合的重要性。接种PP对干发酵香肠的感官品质改善产生了重要的有益影响。
