Abstract:
Tree-ripe ‘Irwin’ Mangoes grown
under greenhouses in Japan have excellent quality.
Unfortunately, their
harvesting period is very limited and storability is very poor.
Therefore, a
method for preserving the fruit quality is highly required.
Temperature and gas
composition are the most important factors affecting the rate of respiration
and ultimately the fruit quality attributes.
Respiration rate is the necessary
parameter for designing the storage conditions.
In the present investigation,
the effects of storage temperature (5, 15, or 25 °C) and gas composition on the
O2 consumption and the CO2 production have been studied
by using the flow through system.
The ratios of the respiration rate under
controlled atmosphere conditions (1.6 to 20.7 % O2, 0.2 to 10.2 % CO2,
balanced with N2) were calculated against the values under normal
air condition.
Data obtained on respiration rate and respiration quotient
suggest that low temperature in combination with CA gas composition around 10 %
CO2 and 5 % O2 will be effective to suppress the
respiration rate of tree-ripe ‘Irwin’ mango.
