NEBI is the browning of juice due to Maillard reactions,subsequently causing colour changes and loss of nutrients. processed by UV-C and thermal, except U15. However, UV-C treated samples, U30 (0.09) and U60 (0.10)showed minimum increase from the control (0.06), when com-pared to thermal pasteurized samples (0.13). For thermal pasteurized samples, there is enhanced formation of browning compounds, subsequently darkening the juice and reaching the highest NEBI value.
