Résumé

Waste water samples collected from a cinnamon bark oil distillery, was extracted and analysed by gas chromatography. The major constituent of the extracted oil solution was cinnamaldehyde (66.21%). Previously isolated and identified fungal pathogens causing anthracnose and crown rot of Embul banana were treated in vitro with oil extract. The oil was fungistatic and fungicidal within the range of 0.64-1.00 mg/ml. Spraying Embul banana with emulsions of the oil extract prior to storage, controlled crown rot enabling banana to be stored for up to 14 days at ambient temperature (28 plus or minus 2 °C) and 21 days at 14 °C; 90% relative humidity in modified atmosphere. A standard fungicide, benomyl treatment and control were included. There was no detrimental effect on the physico-chemical properties such as percentage weight loss, fruit firmness, pH, total soluble solids and titratable acidity due to treatment with oil extract. The evaluation of organoleptic properties showed higher acceptability of oil-treated banana.
