Esters were the most abundant compounds of the aroma volatiles from fresh papaya fruit, with methyl butanoate (48%) as major constituent. Products of benzyl glucosinolate degradation were identified, but no benzyl isothiocyanate was found.\\ | Esters were the most abundant compounds of the aroma volatiles from fresh papaya fruit, with methyl butanoate (48%) as major constituent.

Methyl butanoate, ethyl butanoate, 3-methyl-1-butanol and 1-butanol were found to be the major volatile components of fresh papaya fruit. The esters of lower fatty acids were considered to contribute much to the typical papaya flavour. \\ | Methyl butanoate, ethyl butanoate, 3-methyl-1-butanol and 1-butanol were found to be the major volatile components of fresh papaya fruit.

- | Aroma extract dilution analysis (AEDA) and odour activity value (OAV) determination were applied to estimate the most odour-active volatile compounds from papaya fruit cv. Red Maradol. Overall, esters were the dominant class of constituents. 3-Methylbutanal (0.4mg/kg), methyl butanoate (2.3mg/kg), 3-methylbutan-1-ol (0.8mg/kg), ethyl butanoate (0.8mg/kg), methyl hexanoate (0.3mg/kg), limonene (0.3mg/kg), benzyl isothiocyanate (0.2mg/kg) and some fatty acids and their correspondend esters like dodecanoic acid, tetradecanoic acid, ethyl tetradecanoate, | + | The volatiles of different cultivars of Carica papaya fruits were extracted using liquid-liquid-extraction and stirbar-sorptive extraction (SBSE). Character impact compounds which contribute to the aroma impression were characterized by GC-O, identification and semi-quantification were accomplished with GC-MS. The aroma patterns differ significantly between the genotypes resulting in very different sensory qualities. Especially the existence and content of terpenes show a high variability. A huge number of compounds |

The mustard oil liberated enzymatically on maceration of the fruit seeds in water or an organic solvent, is benzyl isothiocyanate (0.2-0.5%).
