Chemical changes in Apulia table wines as affected by plastic packages

The influence of polymeric packages on the quality decay of red and white Apulia table wine is addressed in this work. In particular, polyethylene terephthalate with oxygen scavenger package compared with polyethylene terephthalate, with a different permeability to oxygen, was used in this investigation. Wine packaged in glass and stored under the same environmental conditions served as the “control” sample. Classical oenological parameters including the anthocyanin fraction and the volatile fraction, were monitored over 7 months assessing the chemical changes related to oxidation and flavor scalping.Polyethylene terephthalate with oxygen scavenger showed a behavior in preserving wine much closer to the glass one with respect to polyethylene terephthalate as evidenced from all the selected descriptors.
