Water evaporation and changes in texture and colour caused by biophysical processes are important in fruit storage. Using various modified atmospheres, fruits of apple cultivars 'Staris', 'Auksis', 'Cortland' and 'Spartan' were stored at +1± 1 °C and relative humidity of 90-95%. The fruits were tested in the Biochemistry and Technology laboratory of the Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry. Fruit texture and the colour parameters: L*, a*, b*, h° and C were measured before and after 8 months of storage. Soluble solids, respiration rate, sugar content and the amount of ascorbic acid were determined with standard methods. It was found that skin firmness of 'Spartan' apples was the highest (355.4 N/cm2). 'Auksis' apples had the softest skin (215.8 N/cm2). Fruit firmness changed slightly when the carbon dioxide concentration in the modified atmosphere was increased. The same tendency was found for flesh firmness at 2% and 4% of carbon dioxide. The amounts of soluble solids and sugars in fruits at 4% CO2 were stable. The obtained results showed that ascorbic acid losses in the modified atmospheres with 2% and 4% CO2 were respectively 18% and 10.5%. Fruit colour properties were more affected in terms of the colour coordinates a* and b*.
