Odour-active compounds in papaya fruit cv. Red Maradol

Application of solid-phase microextraction and simultaneous distillation-extraction combined with GC-FID, GC-MS, aroma extract dilution analysis, and odour activity value were used to analyse volatile compounds from papaya fruit cv. Red Maradol and to estimate the most odour-active compounds. The analyses led to the identification of 137 compounds; 118 of them were positively identified. Twenty-five odorants were considered as odour-active compounds and contribute to the typical papaya aroma, from which ethyl butanoate, benzyl isothiocyanate, 1-hexen-3-one, (E)-β-ionone, and methyl benzoate were the most odour-active compounds.
