Changes of surface colour during broccoli yellowing were evaluated through the hue angle (H) and L⁄ parameters. L⁄ value increased and H value decreased in broccoli during storage. LED green light treatment significantly inhibited the increase of L⁄value, however, no significant (P < 0.05) difference was found between fluorescent treatment and control. Both fluorescent and LED green light treatment prevented the decrease and maintained higher value of H in comparison with the controls
