Abstract:

Statement of the Problem: Increasing the survival of probiotic bacteria and improve the hygienic quality of dairy products using natural preservatives is widely accepted today, It has long been recognized that some essential oils (EOs) have antimicrobial properties and that they can be used as food flavoring agents or preservatives, and for medicinal purposes. However, to establish the usefulness of natural preservatives, they must be evaluated alone and in combination with other preservation factors (such as probiotic bacteria) to determine whether there are synergistic effects and to devise effective combinations. In this study the effect of Teucrium polium, cumin and Mentha longifolia L. EO on Lactobacillus casei survivability and flavor characteristics of yoghurt, cheese and ayran were studied. Methodology & Theoretical Orientation: M. longifolia L. (0, 50, 150 and 300 ppm), T. polium (40, 60 and 80 ppm) and M. longifolia L. (50, 100, 200 and 300 ppm) EOs and Lactobacillus casei (108-109 CFU�?mL) were used in cheese, yoghurt and ayran, respectively, viability of L. casei and organoleptic properties of these dairy products samples were analyzed during storage period. Findings: The survival of L. casei decreased throughout the storage period. Nevertheless, probiotic dairy products and treatment containing medium concentration EOs (T. polium: 60 ppm, M. longifolia: 150 ppm in yoghurt and 200 ppm in ayran) had the highest (P<0.05) viable count of probiotic bacteria. But the lowest concentration of these EOs was the most appropriate treatment (P<0.05) in sensory assessment. Conclusion & Significance: Based on our results, dairy products such as yoghurt, cheese and ayran can be a very suitable food product to carry relevant probiotic bacteria while adding certain herbal EOs.
