The effect of oxygen permeability of packaging material on shelf life of minimally processed and passive modified atmosphere packaged pomegranate arils, cv Wonderful as well as some quality attributes were investigated. Packaging materials having Oxygen transmission rate (OTR) as low as 125-290 cm(3)/m(2)/day were found to provide the gas concentration requirements of 2-5% O-2 and 3-10% CO2 for passive modified atmosphere application of fresh fruits and vegetables. Although color, firmness, anthocyanin, total phenolic content and sensorial and microbial properties significantly changed there was no significant change in pH, total soluble solids and antioxidant activity during storage period at 5C. Microbial counts of total aerobic bacteria did not exceed the legal limit during storage period but sensorial values were below the limit of threshold on 11th day of storage. OTR of packaging material of pomegranate arils should be as low as 125-290 cm(3)/m(2)/day under passive modified atmosphere and its shelf life was determined as 10 days at 5C and 90% Relative humidity (RH).
