Abstract : Avocado (Persea americana), pawpaws (Carica papaya), and mango (Mangifera indica) fruits were separately sealed in low-density polyethylene packages and stored for 8 or 12 days at 20°C to study the effects of ethylene removal on gas concentration changes and retention of fruit freshness under modified atmosphere packages. The changes in steady-state O2 and CO2 partial pressure of fruits in packages with ethylene absorbent were similar to fruits in packages without ethylene absorbent (the control), while the steady-state ethylene concentrations in the control were highest for avocado fruits and lowest for mango fruits. There were minimal effects of ethylene removal on browning or yellowing of the fruit skin and softening of the fruits, while fruit decay was inhibited up to 12 days of storage.
