In this study, the color development of EA-lactose solution was studied as a function of electro-activation time (0–60 min), relaxation duration (0, 24, 48, and 72 h), and storage temperature for relaxation (5, 25, and 45 °C).

The gradual increase of <em>b*</em> showed that the color was intense with the duration of electro-activation and the relaxation time. EA-lactose solutions absorbed light mostly in the UV-B region. To understand the color development, the kinetics were analyzed and were found to follow a zero-order reaction. The relatively lower activation energy showed better performance of the EA isomerization compared to chemical isomerization process. HPLC analyses showed that EA yielded higher lactulose (34.13 %) after 72 h relaxation and 19.44 % galactose, but with an intense yellowish color.
