Quality of Fundy and Blomidon lowbush blueberries: effects of storage atmosphere, duration and fungal inoculation.

 

The response of blueberries (Vaccinium angustifolium cultivars Fundy and Blomidon) to controlled atmosphere (CA) storage in all combinations of 1, 2 or 5% O2 and 0, 5, 10 or 15% CO2, or storage in air at 0 deg C, was investigated. One set of samples was infected with Botrytis prior to storage to determine the effect of CA storage on decay development. Samples were evaluated for firmness, titratable acids, and the number of unmarketable and decayed berries after storage for 2, 4 or 6 weeks. After storage, the berries were held for one week at 10 or 20 deg . Increasing CO2 in the presence of 1-5% O2 reduced decay and percentage unmarketable berries in both cultivars, and maintained titratable acids and berry firmness levels. After 6 weeks of storage, Fundy had 30.5% unmarketable berries in air storage, compared with 8.7% in 15% CO2. Blomidon had 36.0% and 6.8% unmarketable berries in air and 15% CO2, respectively. Decreasing O2 reduced the percentage of decayed berries and maintained titratable ac

ids. Botrytis infection before storage reduced berry quality, but cultivars responded differently. The quality of berries one week after removal from storage was influenced primarily by cultivar, storage time and shelf temperature and not by storage atmosphere.
