minimum inhibitory concentrations (mic) of some essential oils and citric acid were determined against two micro-organisms associated with spoilage of orange juice (saccharomyces cervisiae and leuconostoc mesenteroids) and against four unidentified microorganisms isolated from citrus surface and spoiled orange juice. mic for limonene were obtained less than 5% w/v aqueous against saccharomyces ...

Natural compounds including essential oils (EOs) are used to inhibit the pathogenic bacterial growth in foods. The objective of this study was to investigate the combined effect of Trachyspermum ammi EO and propolis ethanolic extract (PEE) on some food pathogenic bacteria. In this study, the effect of T. ammi EO and PEE at different concentrations, individually and in combinat...
