A year long storage study was undertaken to evaluate an oriented polyethylene terephthalate (OPET) container for use with hot filled juice. Freshly made juice as well as single strength juice reconstituted from commercial apple juice concentrate were evaluated. The results indicated that the oxidation of the juice by way of oxygen permeation through the OPET barrier was slow enough to allow for a satisfactory shelf life as compared to glass‐packaged samples over a 6–9 month period. Surface‐to‐volume effects did not become significant until late in the study. Difference and preference tests were used to establish shelflife comparison between OPET packages and glass‐packaged products.
