  • Title: Effect of storage on some volatile aroma compounds in fresh-cut cantaloupe melon.
    Author: Lamikanra O, Richard OA.
    Journal: J Agric Food Chem; 2002 Jul 03; 50(14):4043-7. PubMed ID: 12083880.
    Abstract:
    Changes in volatile aroma constituents of fresh-cut cantaloupe melon with storage were determined by headspace solid-phase microextraction gas chromatography-mass spectrometry. The compounds isolated from the fruit immediately after cutting were predominantly aliphatic and aromatic esters. Storage of fruit at 4 degrees C caused a considerable decrease in concentration of esters and synthesis of the terpenoid compounds beta-ionone and geranylacetone over a period of 24 h. This change in the volatile profile with storage is consistent with that of a stress-induced defense response in the cut fruit as an adaptation process to tissue exposure and cell disruption. The same effect occurred in fruit stored at 22 degrees C and in those treated with sodium azide and ascorbic acid prior to storage. Fruit treated with ascorbic acid and sodium azide had higher concentrations of beta-ionone and geranylacetone and retained these compounds better with storage time. The reduction of esters appears to be an important early reaction step in the loss of freshness during storage of fresh-cut cantaloupe.
