After UV-C treatment and thermal pasteurization, no significant changes occurred in physicochemical properties.
A significant increase in extractability of carotenoids (6%), polyphenols (31%), and flavonoids (3%) were observed in
juice exposed to UV-C light for 15 and 30 min, when compared to freshly squeezed juice. Besides that, enhancement
of antioxidant activity was observed after UV-C treatment. Thermal pasteurization and UV-C treatment exhibited
significant reduction in microbial load and prolonged shelf-life of juice.
