Ethylene and the adaptive response of mango to hypoxia

M.C.C. Lizada, R.A. Rumbaoa
'Carabao' mangoes were subjected to modified atmosphere packaging (MAP) at 13°C in low density polyethylene bags (30 µm) with or without ethylene adsorbents. For most treatments, fruits transferred to air after 2 weeks of MAP exhibited internal breakdown (IB). Provisions for ethylene removal protected the fruits subjected to MAP, as evidenced by significantly reduced IB incidence and normal ripening in air after 3 weeks of holding. A fermented odor and transient softness of fruits were evident upon opening bags containing these fruits, but the odor dissipated and a texture typical of green fruit regained after fruit exposure to air. This study verified that ethylene removal is critical in managing the susceptibility of the 'Carabao' mango to anaerobiosis leading to the development of IB. As with controlled atmosphere (CA) holding, the 'Carabao' mango requires a period of more than two weeks to adapt to low oxygen levels.
