| Abstract: |
| In this study，modified atmosphere packaging（MAP）of four different plastic films was conducted
on dwarf banana‘FenzaNo.1’in order to investigate the shelf storage effects at room temperature（22±2℃）.
Packages of polyethylene film 0.03 mm（PE3c），0.05 mm（PE5c），0.07 mm（PE7c）and biaxially oriented
polypropylene film 0.03 mm（BOPP）were used after banana was treated with preservatives and ethephon for 1 day.
An ethylene absorbent by independent research and development was put in each package. MAP was created for banana
storage. Results showed that CO2 rose up to 7%-12% and O2 dropped off to 5.68%-7.53% in the mini-environment
closed by BOPP. High CO2 and low O2 concentration decreased ethylene formation and postponed post-ripening. Fruit
hardness declined and peel turned yellow obviously slowly. Increment of total soluble solids，organic acid and decrement
of Vitamin C were obviously retarded. Fruit was maintained with low weight loss and high good fruit rate. Shelf life
prolonged to more than 12 days. Fruit quality was relatively good at room temperature during shelf storage. The storage
effect of PE7c，PE5c and PE3c ranked afterwards in order. It is concluded that BOPP is better than common-used PE.
BOPP is suitable for shelf storage of dwarf banana at room temperature after artificial ripening treatment. |
