Both ethyl ester and alcohol contents were higher in fruits of cv Mirado when compared with cv Rony. All the pre-treatments caused a decrease of ethyl esters, while alcohols remained stable in cv Mirado and in DIS pre-treated fruits of cv Rony, and increased in the air dehydrated fruits of cv Rony (Figs.5and6). Duringthe freezing process there was an increase of alcohols in both cultivars, with the exception of the DIS-treated fruits of cv Rony, while there was no modification of the ethyl ester content. The aroma compounds analysed decreased during the four months of frozen storage, independently of the cultivar and the pre-treatment
(data not reported).
