The objective of this study was to determine the extent to which acetaldehyde (AA) and formaldehyde (FA) migrated from polyethylene terephthalate (PET) bottles into mineral water during storage at 25 and 35oC for 240 days. Generally, AA and FA were observed to migrate more at 35oC than at 25oC. The amount of FA in the samples irradiated under UV lamps was higher than in those stored in the dark over the storage period and vice versa for AA. Using a triangular test, the sensory panels distinguished a difference between one sample and the other two mineral water samples that had been exposed to UV lamps after 60 days of storage at 35oC (p<0.05). At this time, FA and AA concentrations were measured at 267.4 and 515.3 g/L, respectively. After 120 days, an independent mineral water sample from the other two samples in all treatments could be distinguished by the panel members at a significance level of p<0.001.
