Effect of acetaldehyde and anaerobiosis as postharvest treatments on the quality of peaches and nectarines.

Fruits of 3 peach cultivars (Almog, Hermoza and Texas) and one nectarine cultivar (Mayglo) were treated for 24 h with acetaldehyde vapour (2000 or 3000 p.p.m.), 86% CO2 or 97% N2 immediately after harvest. The fruits were then held for 7 days at 20 deg C, or stored for 2.5 weeks at 0 deg , 90% RH before being kept at 20 deg . Treated fruits softened more slowly than control fruits which had been kept in humid air for 24 h before holding at 20 deg . Insoluble pectin content remained higher and polygalacturonase activity increased more slowly in treated fruits than in control fruits. Immediately after treatment, ethanol content was much higher in treated fruits but decreased during the period at 20 deg and was similar to that in control fruits after 7 days. Ethanol content of control fruits increased during ripening. Ethylene production was inhibited by both CO2 and N2 treatments, with the latter being more effective. Taste tests after 5 days at 20 deg revealed a preference for the treated fruits over the control fruits. N2-treated fruits were generally rated highest.
