The quality changes of the 'Braeburn' apple variety were determined during a normal (air) and controlled atmosphere storage period. Harvested apples were stored at 0 degrees C temperature and 90+/-5% relative humidity conditions during 6 months in normal (air) and 10 months in controlled atmosphere (1% O-2 and 1% CO2, 2% O-2 and 2% CO2, 1% O-2 and 3% CO2, 3% O-2 and 5% CO2). Weight loss, fruit flesh firmness, skin colour, soluble solid contents and titratable acidity were determined at monthly intervals for normal (air) and at two months intervals for controlled atmosphere conditions. Controlled atmosphere (CA) gave better results than normal (air) atmosphere (NA) in terms of weight loss and fruit flesh firmness. The titratable acidity of apples stored in controlled atmosphere was higher than those stored in normal (air) atmosphere. The results showed that 'Braeburn' apple variety, stored in controlled atmosphere conditions, could provide for the demands of high quality products on European markets.
