Optimizing parameters for controlled atmosphere storage of apples.

Research on various aspects of controlled atmosphere storage, including the development of specific recommendations for storage temperature, and O2 and CO2 concentrations for various cultivars, carried out at the Michigan State University Postharvest Physiology Laboratory is described. A controlled atmosphere of 1.5% O2 with up to 3% CO2 has been found to be the best generally applicable atmosphere to delay ripening and minimize physiological disorders of all apple cultivars tested to date as grown under Michigan conditions. A storage temperature of 3 deg C was optimum for CA at 1.5% O2 with up to 3% CO2 for McIntosh and Empire fruits and was also suitable for Idared, Jonathan, Mutsu (Crispin) and Northern Spy fruits. Storage at 0 deg with the same atmosphere resulted in excellent quality retention in Red Delicious, Golden Delicious, Law Rome, Jonathan, Idared and Mutsu fruits. Scrubbing ethylene during CA storage delayed ripening of preclimacteric McIntosh fruits and to a lesser extent of Empire fruits stored at 1.5% O2. Other cultivars stored at 1.5% O2 showed no additional benefit on ripening delay from ethylene removal. The incidence of superficial scald on scald susceptible cultivars not treated with DPA [diphenylamine] was nil or negligible in CA storage where CO2 was scrubbed by ventilation with an air separator.
