During 12 d shelf life after fresh cut, the colour of potato slices from curing treated potatoes were consistently much better than those from control (Figs. 1B,D, and 3A). Significantly lower levels of browning of potato slices and better quality in overall visual quality from the curing-treated potatoes than control slices (P < 0.05) was observed ( Fig. 2). Visual quality declined gradually after fresh cut to 12 d at 3 °C. This is correlated well with the decrease of “L” and the increase of “a” value in both curing and control. Higher “L” and lower “a” value were found in freshly cut slices from the cured potato throughout the 12 d shelf life period ( Fig. 1B,D). Better “b” value in the slices from curing potato than those in the control potato also indicates the less browning occurred ( Fig. 1F). The data above indicated that the curing treatment was effective in the preventing surface browning and maintaining visual quality of fresh-cut potatoes.
