Effect of Bunium persicum essential oil, NaCl, Bile Salts, and their combinations on the viability of Lactobacillus acidophilus in probiotic yogurt

The probiotic yogurt, with additional essential oil researches, has increased recently. Bunium persicum Boiss is a critical medicinal wild growing plant in Iran dry areas. In this study, Lactobacillus acidophilus was exposed to stress B. (BEO), NaCl, bile salts, and their combinations by 50 minimum inhibitory concentration (MIC) then inoculated the yogurt samples, which were stored at 4°C for 28 days. Indepen-dent parameters article are BEO 500 1000 ppm that physicochemical, sensory properties, L. of viability samples assessed within time. A steady increase syneresis percent-age acidity observed, while pH values reduced all samples. survival decreased during storage time treatments. addition, scores showed reduction trend rate bacteria also impacted redox potential. Increasing oxidation resuscitation potential increasing hydrogen peroxide due metabolic activity among factors reduce population storage. most under compared other treatments may be slight changes period than Generally, it can argued usage BEO, salts MIC 50% refrigerator 21 days provided suitable environment transmission acidophilus, as recommended consumer and, therefore, current results confirmed addition these materials improved physicochemical characteristics yogurt.
