Synergic Effect of Cinnamaldehyde and Eugenol Against Aspergillus niger on Surface of Tomatoes

The inhibitory effect of the combination of cinnamaldehyde and eugenol, at a ratio 1:1 of against Aspergillus niger, was tested at different concentrations (10-100 µg/ml) o­n malt extract agar (MEA) and o­n the surface of tomatoes. The minimal inhibitory concentrations (MIC) for A. niger at 25 °C o­n MEA and o­n the surface of tomatoes were 30 µg/ml and 20 µg/ml, respectively. Combination of cinnamaldehyde and eugenol reduced the percentage of decayed tomatoes. Tomatoes treated with 20 µg/ml of cinnamaldehyde and eugenol at a ratio of 1:1 appeared to be free from any fungi o­n the surface, for at least 21 days under storage conditions of 20°C and 90%RH. Therefore, combination of cinnamaldehyde and eugenol could be an alternative to chemicals for control of postharvest spoilage fungi o­n fruits or vegetables.
