ABSTRACT :
Carbon dioxide and oxygen concentrations which delayed softening and loss of green colour at 15 deg C without adverse effects on the quality of Bramley's Seedling and Cox's Orange Pippin apples were defined using flow through systems. Modified atmospheres (MA) were then developed for their post-storage marketing in 40-lb (18-kg) cardboard cases lined with suitable polymeric films. Low density polyethylene (LDPE, 30 mu m) liners, closed by envelope folding, provided effective, reproducible atmospheres of 7-10% CO2 and 5-7% O2 for Bramley apples during a simulated 4-week marketing period under ambient conditions. Since similar films applied to Cox's Orange Pippin apples resulted in over-modification of the atmosphere and fruit tainting, micro-perforated LDPE liners were used to provide increased gas permeability without sacrificing mechanical strength; envelope folding of the liner gave uniform atmospheres in replicate cases of fruits. Shelf-life benefits were comparable to those found earlier for
the 1-kg retail pillow packs. These new types of box liner are now being introduced into the UK fruit market.
