4. Conclusion
Pomegranate juice color was assessed based on the anthocyanin
content and chromatic parameters. The variations of anthocyanin
content and chromatic parameters were relatively less at 4 C but
were considerable at 20 and 37 C. The best temperature for
long-term storage was 4 C, which can maintain marketing and
nutritional quality of juices for acceptable periods of time. Degradation
of pomegranate juice anthocyanin follows first-order reaction
kinetic during storage. Variation of juice pigments is highly
correlated with a variation in CIE values of all juices. The best correlation
was found for DE. Thus, Hunter color values may be used
to predict the levels of total anthocyanin content of pomegranate
juice.
