Mondial Gala apples were harvested at commercial maturity and stored at 1 °C under either air or
controlled atmosphere (CA) conditions (2 kPa O2/2 kPa CO2 and 1 kPa O2/1 kPa CO2), where they
remained for 3 or 6 months. Data on emission of selected volatile esters, alcohol precursors, and
activity of some aroma-related enzymes in both peel and pulp tissues were obtained during subsequent
shelf life of fruit and submitted to multivariate analysis procedures. CA storage caused a decrease in
the emission of volatile esters in comparison to storage in air. Results suggest that lessened ester
production was the consequence of modifications in activities of alcohol o-acyltransferase (AAT) and
lipoxygenase (LOX) activities. For short-term storage, inhibition of lipoxygenase activity in CA stored
fruit possibly led to a shortage of lipid-derived substrates, resulting in decreased production of volatile
esters in spite of substantial ester-forming capacity that allowed for some recovery of fruit capacity
for ester emission during the shelf life. For long-term storage, strong inhibition of AAT activity in CA
stored fruit in combination with low LOX activities resulted in unrecoverable diminution of biosynthesis
of volatile esters. |
