Online published on 2 January, 2017. Abstract The freshly strawberry fruits of cv. Sweet Charlie were plucked at approximately 2/3rd colour development stage and packed in plastic punnets of 150g size. Different readily available packaging materials viz., low-density polyethylene (LDPE) 25, 50 and 75 micron, polypropylene (PP) 25 micron, cellophane paper and cling film were wrapped around each punnet to create a passive modified atmospheric condition. All the punnets were stored in refrigerated storage temperature (i.e., 6±2°C). The various qualities attributes viz., TSS, titratable acidity, ascorbic acid, total and reducing sugars were estimated daily throughout the storage period. The result inferred that, the TSS (6.50–6.23°Brix), titratable acidity (0.93–0.63%), ascorbic acid (35.81–20.89 mg/100g), total sugars (5.28–4.63%) and reducing sugars (4.13–3.62%) were found to be decreased with the prolongation of storage periods. No significant variation was recorded for different packaging materials, except for ascorbic acid in strawberry fruits packed with LDPE 50 (31.86 mg/100 g) and 75 micron (30.94 mg/100 g) packaging films was retained.
