An evaluation of microperforated polyethylene film bags for storage of 'Cox's Orange Pippin' apples.

Cox's Orange Pippin apples harvested on several dates between mid-Feb. and early Mar. were packed in cartons fitted with either microperforated polyethylene bags (25 micro m thickness, 50 microperforations/bag) or commercial polyethylene bags (25 micro m thickness, 24 x 9 mm holes) or not fitted with bags. The fruits were stored at 1 deg or 3 deg C, for up to 16 weeks. After storage at both temperatures, fruits stored in microperforated bags were greener and firmer than fruits stored in commercial bags or without bags. However, the benefits of using microperforated bags declined with increasing storage period. After 14-15 weeks' storage, the incidence of superficial scald was higher in early-harvested fruits stored in microperforated bags (94.2 and 91.3% at 1 deg and 3 deg , respectively) than in early-harvested fruits stored in commercial bags (84.8 and 16.4%) or without bags (72.2 and 26.7%). Data on the incidence of senescent breakdown, low temperature breakdown and core flush for each storage treatment are tabulated. The overall results indicate that the potential for commercial use of microperforated bags is limited to short-term storage.
