Summary

The effects of modified atmosphere packaging on the fruit quality of highbush blueberries (Vaccinium corymbosum L., cv Lateblue) were investigated. Blueberry fruit were packed into polypropylene film types and filled with 5 different atmosphere (10, 15, 20% CO2, and 5% O2; 15% CO2, and 10, 15% O2) or normal air (control). Blueberry packages were than stored in a cold room at 0°C and 90-95% relative humidity for 28 days. Physical, chemical and nutraceutical attributes were assessed during the storage period: weight loss, flesh firmness, total soluble solid content, titratable acidity, ph, anthocyanin contents, phenolic contents and total antioxidant capacity. Statistical analysis of data showed significant differences between the packaging and control berries. Total soluble content, anthocyanin contents and phenolic contents were higher for the control berries than for packed fruits. Storage in plastic films reduced weight loss and slowed down the deterioration in visual quality.
