The effects of various atmospheres during controlled atmosphere (CA) storage, of holding fruits in air for various periods prior to CA storage, of alternating storage in CA with storage in air, and of stepwise application of CA on the incidence and severity of Braeburn browning disorder (BBD) and other quality attributes in Braeburn apples harvested in Central Hawke's Bay, New Zealand, are described. Delaying the application of CA storage by holding fruits in air at 0 deg C for 2 weeks prior to storage reduced BBD incidence to 1% in fruits stored in 2.5:0, 3.0:0, 2.0:1.0 or 3.0:1.0 kPa O2:kPa CO2. BBD incidence was 6%, 3%, 37% and 12%, respectively, in fruits stored in the above atmospheres but with only one-day delay in application of CA storage. Application of CAs at a slower rate or in a stepwise fashion also reduced the incidence and severity of BBD. The results suggest that Braeburn apples can become acclimatized early in storage such that the disorder is expressed at a lower level. It is r
ecommended that Braeburn apples should not be stored at CO2 levels above 1%.
