Recent studies show that hyperbaric storage at room temperature (HS-RT) could be an interesting method for food preservation. In this paper, the effect of HS-RT on color degradation was evaluated in strawberry juice. To do so, strawberry juices were stored for 1, 2, 5, 7, 10, and 15 days at three pressure levels (0.1, 50, and 200 MPa) and 20 degrees C. The evolution of the instrumental color parameters L*, h degrees, C*, and Delta E*, total phenolic and anthocyanin contents, polyphenoloxidase and peroxidase activities, and percent polymeric color (PPC) during storage was compared in samples maintained at different pressures. Color differences due to the storage pressure were slight to the naked eye, but instrumentally perceptible on some of the storage days. The results showed that the storage pressure affected some mechanisms of color degradation. Thus, significant peroxidase inactivation (on storage days 5, 7, and 15) and lower PPC (on storage days 5, 7, and 10) were found in the samples stored at 200 MPa when compared with those maintained at atmospheric pressure.
