All five bottles plus a glass jar control were filled with commercial brand bottled water from a five gallon polycarbonate container. After aging for five days at room temperature, portions of the water were placed in beakers, numbered to correspond to the bottle sampled. The numbered beakers were then used in a "blind" aroma and flavour test.
The procedure was repeated for samples aged for five days at 45 degrees centigrade.
The Enviroclear® copolymer bottle has the lowest total impact ratings in all tests and results matched the control in three out of four tests. The character notes were the same as the control plus a slight fruity note.
The bottles tested for aroma and flavour were:
For bottles of water stored at room temperature, the aroma and flavour test results were:
For bottles of water stored at 45 degrees centigrade, the aroma and flavour test results were:
The control suggests the following character notes to be common to the water used for
the tests, which was commercial brand bottled water from a five gallon polycarbonate container:
The Enviroclear® copolymer bottle had the least difference from the control in aroma and flavour of the five polymer bottles evaluated.
