Occurrence and growth of fungi may cause spoilage and reduce dramatically quality and safety of white cheeses. A considerable interest both in the industry and scientific research has developed on the preservation of foods by the use of essential oils (EO) to effectively retard fungi growth and mycotoxin production. Therefore, the aim of this work was to investigate the chemical compositions and antifungal properties of several Iranian EOs against fungi contaminating Iranian white cheese. In this study, the EOs including Trachyspermum ammi, Satureja hortensis and Mentha piperita were used. The chemical compositions of EOs were characterized using GC-MS. Antifungal properties of EOs against isolated fungi was determined by disk diffusion agar, minimum inhibitory concentration (MIC), and minimum fungicidal concentration (MFC). According to the results from disk diffusion tests, the most sensitive fungi against all EOs was Trichoderma harizanum. In this regard, Paecilomyces variotii, Aspergillus niger, and Aspergillus oryza were highly resistance against all EOs. Also, The results of MIC and MFC indicate that the most sensitive fungi to all three EOs of T. ammi, S. hortensis and M. piperita was T. harizanum with MIC values of 0.281, 0.250 and 0.562 µL/mL, respectively, and its MFC values was 0.562, 0.562 and 1.125 µL/mL, respectively. Also, among the studied EOs, T. ammi and S. hortensis showed the highest antifungal activity, while M. piperita showed lower antifungal properties in compared to the other two EOs. Based on the results, it can be said that S. hortensis and T. ammi EOs have good antifungal activities and can be used in food industries, medical pharmacology, health affairs, and antifungal elements.
