Effects of PET packaging on the quality of an orange juice made from concentrate
An orange juice made from concentrate was conditioned in three different PET (PolyEthylene Terephtalate) and glass packagings. Influence of storage conditions (length of storage, light, oxygen) on vitamin C content, browning index, and colour were measured. Results show that permeability to oxygen of PET packagings is the major factor detrimentally affecting the above parameters.
