Storage and handling effects on a CO2-related internal browning disorder of 'Braeburn' apples.

Fruits of apple cv. Braeburn can develop of an internal disorder (Braeburn browning disorder, (BBD)). Factors associated with the development of BDD were investigated. Susceptibility to injury was greater in fruits exposed to 2 or 5 kPa CO2 than to 0 kPa CO2 during storage. Susceptibility also increased with decreasing O2 partial pressure in the range of 5 to 1 kPa in the storage atmosphere. However, fruits stored in 1 kPa O2 remained firmer than those stored at higher partial pressures, regardless of CO2 concentration. BBD appeared to develop during the first 2 weeks of storage, and delays in air at 0 deg C prior to controlled-atmosphere (CA) storage decreased incidence and severity of the disorder. BBD was also reduced when the time to establish CA conditions was prolonged. It is suggested that Braeburn apples should be stored under CA conditions of less than or equal to 1.0 kPa CO2 and 3.0 kPa O2. It is also suggested that delayed application of CA for 2 weeks after fruits enter cold storage

may reduce BDD development.
