Lowering O
2
and raising CO
2
can maintain the quality of many fresh fruits for extended periods.
However, exposure of fresh product to O
2
levels below their tolerance level can increase anaerobic
respiration and lead to the development of off-flavor. Storage of fruit under controlled atmosphere
(CA) conditions can reduce the capacity of several fruit to produce ethylene and alter production of
aroma volatiles [109]. Storage of peach fruit cv “Rich Lady” for 15 days, under 3% O
at
2 °C, improved juiciness, sweetness, perception of flavor, emission of aroma volatile compounds and
sensory acceptance in comparison with fruit stored in cold air [110]. Decreasing O
