The effect of Juniperus communis L. essential oil (JEO) addition at concentrations of 0.01, 0.05 and 0.10 µL/g on pH, instrumental parameters of color, lipid oxidation (2-Thiobarbituric acid reactive substances (TBARS)), microbial growth, texture and sensory attributes of dry fermented sausages produced with different levels of fat (15 and 25%) and sodium nitrite (0, 75 and 150 mg/kg) was assessed. Reduced level of sodium nitrite (75 mg/kg) in combination with all three concentrations of JEO (0.01–0.10 µL/g) resulted in satisfying physico-chemical (color and texture) properties and improved oxidative stability (TBARS < 0.3 mg MDA/kg) of dry fermented sausages produced with 25% of fat. However, sausages produced with 0.10 µL/g of JEO had untypical flavor. No foodborne pathogens (Escherichia coli, Listeria monocytogenes, Salmonella spp. and sulfite-reducing clostridia) were detected in any sample throughout the storage period (225 days). The results of this study revealed significant antioxidative activity of JEO and consequently its high potential as effective partial replacement for sodium nitrite in dry fermented sausages.

面向更健康肉类产品的新配方:杜鹃花精油作为干发酵香肠中亚硝酸钠的替代品。

分别以0.01、0.05和0.10 µL / g的浓度添加杜松香精油(JEO)对pH,颜色的仪器参数,脂质氧化(2-硫代巴比妥酸反应性物质(TBARS)),微生物生长,质地的影响评估了不同脂肪含量(15%和25%)和亚硝酸钠含量(0、75和150 mg / kg)生产的干发酵香肠的感官属性。亚硝酸钠(75 mg / kg)的减少与三种浓度的JEO(0.01–0.10 µL / g)的结合使用,可达到令人满意的物理化学(颜色和质地)特性并提高了氧化稳定性(TBARS <0.3 mg MDA /公斤)干发酵香肠,脂肪含量为25%。但是,以0.10 µL / g的JEO生产的香肠具有不典型的味道。没有食源性病原体(大肠杆菌单核细胞增生李斯特菌沙门氏菌。在整个存储期间(225天)中,任何样品中都检测到了硫酸盐和还原亚硫酸盐梭状芽孢杆菌。这项研究的结果表明JEO具有显着的抗氧化活性,因此,它具有作为干发酵香肠中的亚硝酸钠的有效部分替代品的高潜力。
