The change in color of MF-clarified pineapple juice stored at 4,
27, and 37 C were also monitored over 6 months. The changes in
color of MF-clarified pineapple juice across the duration of the
shelf-life study are shown in Fig.1. The L value of clarified juice
stored at 4 C was much higher than those stored at 27 C and
37 C (P < 0.05). The decrease in L
values suggested that the clari-
fied juices turned darker due to the non-enzymatic browning reaction
during temperature-abused storage. The a value did overall
not significantly change during storage at different temperature
level
