Based on a successful experiment of a special low oxygen CA combination storage, 2394kg apples were treated in a chamber enclosed by 0.12mm thickness of PE film, gas composition was adjusted by nitrigen gas during the first 4 months; then the PE chamber was sealed and the apples were in MA storage during next 2 months. The results indicted that the oxygen level in the PE chamber could be adjusted to 2% low oxygen level and carbon dioxide could be maintained in the ideal range during the first 4 months. Then, when gas composition was not adjusted, it could still be mainrained at 6.6%-10.6% O2 and 8.6-9% CO2 during next 2 months. After 6 months of storage, the treated apples kept good fresh appearance, low scald incidence (1.7%) , low decay rate, high flesh firmness and high chlorophyll level. Furthermore, the apple scald incidence was only 5.9% after another 51 days of cold storage.
