Abstract : Cultivars Tommy Atkins and Keitt (the main cultivars grown in Florida) were analysed for volatile aroma components. Seven new constituents were identified. The 2 cultivars gave similar results, monoterpene hydrocarbons being the major group of volatiles (> 90%) and car-3-ene the most abundant component (> 60%) present. Results were compared with those already documented for other cultivars, and wide variation in the major monoterpenes detected was demonstrated. Volatiles of under- and overripe fruits (cv. Keitt) were compared with those of the fully ripe fruit. The concentrations of sesquiterpenes increased and those of esters decreased during ripening. Various new components, all alcohols, were detected in the overripe fruits. The effects on the volatile constituents of storing sliced fruit at 10° and -15°C are also reported. Aroma deteriorated during storage at 10°, but freezing maintained the volatile composition close to that of the ideal fruit.
