Abstract

The antifungal activity of essential oil of Rosmarinus officinalis L. and its impact in saving dates has been studied. R. officinalis L. provided a yield of 1.8% essential oil. The antifungal activity of this oil was tested against seven fungal strains isolated from dates and wheat. All fungal strains were inhibited at low concentration of 1/1000. The inhibitory effect of this oil on fungal growth suggests prospects for its application in the food industry. The microbiological analyses of dates showed the existence of a fungal flora dominant by Penicillium and Aspergillus. Besides, the influence of the addition of R. officinalis L. and/or its essential oil on the physico-chemical and microbiological quality of dates showed a decrease in humidity, the pH, increase in the acidity and a reduction of the microbial flora. On the other hand, the results of the sensory analyses showed the acceptability of dates preserved with the powder of R. officinalis.
