There is currently a very high demand for all forms and preparations of medicinal plants worldwide. Accordingly, hops has been drawing significant attention in recent years. Hops is a medicinal plant with various applications in traditional medicine. In the present research work, antifungal effect of hops flower ethanolic extract on S. cerevisiae and some bread spoilage molds (Aspergillus niger, A. flavus, Penicillium chrysogenum, P. citrinum, Rhizopus oryzae and Rhizomucorspp. ) was investigated. The antifungal effect was determined by using broth dilution susceptibility test. Results showed that the ethanolic extract of hops flower had the ability to prevent mold growth on bread samples. Inhibitory concentration of the extract was in the range of 1.875 to 3.3 mg/ml. The extract had no effect on Saccharomyces cerevisiae in the concentrations of 0-15 mg/ml. It was concluded that ethalonic extract of hops flower has remarkable negative effects on food spoilage mold growth, especially bread spoilage molds. To apply this extract as a natural food preservative, further researches are required.
