摘要: 以模仿葡萄球菌(Staphylococcus simulans)NJ201接种发酵香肠为实验组,自然发酵香肠为对照组,测定香肠的pH值、色差、质构、过氧化值(peroxide value,POV)、硫代巴比妥酸反应物(thiobarbituric reactive substances,TBARS)值、羰基含量、总巯基含量、挥发性风味物质的种类和含量,探究S. simulans NJ201对发酵香肠品质及氧化稳定性的影响。结果显示:在香肠发酵成熟过程中,接种S. simulans NJ201能够显著降低发酵香肠的pH值(P<0.05),改善香肠的色泽与质构特性;实验组香肠的POV、TBARS值及羰基含量显著低于对照组(P<0.05),总巯基含量显著高于对照组(P<0.05);实验组香肠的挥发性风味物质种类及含量均高于对照组。综上,接种S. simulans NJ201能改善发酵香肠的口感并增强风味,有效降低发酵香肠脂肪氧化和蛋白质氧化程度,提高发酵香肠的氧化稳定性。

Abstract: Fermented sausages were manufactured with Staphylococcus simulans NJ201 as a starter, and naturally fermented sausages were used as a control. The pH, color parameters, texture, peroxide value (POV) and thiobarbituric acid reactive substances (TBARS) value, protein carbonyl content, total sulfhydryl content, and volatile flavor composition in fermented sausages were measured to explore the effect of S. simulans NJ201 on the quality and oxidative stability of fermented sausages. The results showed that inoculation with S. simulans NJ201 significantly lowered the pH value of fermented sausage during its fermentation and maturation (P < 0.05), and improved the color and the texture characteristics. The POV, TBARS value and protein carbonyl content of the inoculated group were significantly lower than those of the control group (P < 0.05), whereas the sulfhydryl content was significantly higher than that of the control group (P < 0.05). The number and amount of volatile flavor substances in the inoculated group were higher than those in the control group. In summary, inoculation with S. simulans NJ201 can improve the taste and enhance the flavor of fermented sausages, effectively inhibit fat oxidation and protein oxidation and increase the oxidative stability of fermented sausages.

Key words: Staphylococcus simulans NJ201; fermented sausages; lipid oxidation; protein oxidation; volatile flavor compounds
