Effect of pre-storage treatments on mango fruit ripening.

ABSTRACT :

 

The effectiveness of pre-storage treatments of nitrogen (low oxygen), heat and ethanol and acetaldehyde vapours were examined for their potential for improving mango storage. Mature green mangoes (cv. Keitt) were treated with low oxygen (3% oxygen, 97% nitrogen) for 72 h, acetaldehyde (0.12%) and ethanol (1%) vapours for 24 h or heat (38 plus or minus 2 deg C) for 48 h prior to storage at 14 deg . The nitrogen and ethanol treatments induced substantial increases in acetaldehyde and ethanol concentrations in the fruits. Initially the firmness of the nitrogen-treated fruits remained higher than that of control fruits, although later in storage this effect was lost. Differences in ripening were reflected in TSS contents and acidity levels, nitrogen maintaining a higher acidity and lower TSS content (less mature) whereas heat treatment resulted in lower acidity and higher TSS content (more mature). Ethanol and acetaldehyde treatments showed no effect. The use of a pre-storage treatment of nitrogen t

herefore had a beneficial effect on retarding ripening, although as storage progressed this effect was lost.
