| Abstract:
The effect of normal atmosphere storage at O°C on volatiles was studied in peaches (cvs. Redhaven and Glohaven) and nectarines (cv. Maria Laura) picked at the commercial harvest. Volatiles were analysed by dynamic headspace/cGC and GC/MS analyses. Qualitative and quantitative volatile compositions were markedly different among cultivars; at harvest, Redhaven produced the highest amount of total volatiles, total lactones, terpenoids, benzaldehyde and esters, while Maria Laura showed the lowest amount of these compounds. Total volatiles increased during storage in Glohaven, while they decreased in Redhaven and Maria Laura. Terpenoids and esters were the major class of compounds in Maria Laura nectarines at harvest and after storage, while lactones were the principal components in Glohaven and Redhaven peaches. Glohaven peaches had better storability, while Maria Laura nectarines, even being less flavoured, always emitted terpenoids and esters, responsible for the floral characteristic of its aroma. | |
