Effect of storage temperature and atmosphere on Jonathan apples in cool store

Abstract

Queensland-grown Jonathan apples appear to have a shorter storage life than those grown in the southern States of Australia but controlled atmospheres increase storage life. The results indicate that controlled atmosphere storage gave the best control of mould and bitter pit and the lowest percentage of total disorders. Soggy breakdown was significantly reduced both by controlled atmosphere storage and the falling temperature technique. However, air storage at 36°F and the falling temperature storage gave the firmest fruit. This is apparently due to the lower holding temperatures of these two treatments, as in earlier work (Carroll 1965) controlled atmosphere storage at 36°F gave significantly firmer fruit than air storage at 36°F.
