The responses of Bramleys and Coxs apples to modified atmosphere (MA) retail packaging were studied in samples of fruit removed from controlled-atmosphere (CA) storage at monthly intervals through the marketing season, packed in MA or perforated control packs and held under simulated marketing conditions at 15C. The degree of modification of the pack atmospheres and the effects of MA packaging on fruit ripening changes were influenced by the duration and conditions of storage prior to packing. In addition, differential effects of MA packaging on the extent of retardation of flesh softening and skin yellowing were found as the storage period was extended. During 2 or 4 weeks at 15C, however, MA packs made from low density polyethylene (LDPE, 30 p) were effective in retarding changes in firmness and skin colour of Bramleys, previously stored for < 22 weeks (October-March) in 8% C02+ 13% O2 or for < 30 weeks (October-May) in 6% C02+3% 02. Similarly, during a 2-week marketing period at 15C, LDPE or ethylenevinylacetate (EVA, 30 II.) MA packs were effective in retarding some ripening changes in Coxs previously stored for < 31 weeks (Oc- tober-May) in < 1% C02+1.25% 02. The practical benefits of MA retail packaging for the marketing of apples are also discussed. 相似文献
