Abstract
Mango cv. ‘Choke Anan’ fruits were stored in an atmosphere consisting of 2%, 5%, 10% O2 in N2 or in air (21% O2) for 4 weeks at 15°C. Following storage in low-O2 atmosphere, the fruits were transferred to ambient air at 20°C and allowed to ripe naturally.
Fruits stored in 2% O2 exhibited the greatest suppression in CO2 production rates after transfer to ambient air compared to higher O2 levels.
The respiratory quotient (RQ) values of fruit after storage in low-O2 atmospheres for 4 weeks were close to unity, indicating the absence of anaerobic metabolism.
Total sugar content of ripe fruit after storage in low-O2 atmosphere for 4 weeks was significantly higher than the air-stored fruit.
This study indicates that the respiratory metabolism and chemical compositions of ripe fruits were not affected as a result of storage in 2% and 5% O2 atmosphere for up to 4 weeks at 15°C.
