(Total carotenoid) Juice samples subjected to UV-C exposure (U15 and U30) U15 sample showed the highest enhancement in extractability of carotenoids (6%) when compared to the control. After 60 min of UV-C treatment, no significant changes in carotenoid content were observed. Therefore, carotenoids. Thermal pasteurized juice samples showed significant decrease in carotenoid content (48.92 _g/100 ml) when compared to the control (82.03 _g/100 ml).
