In order to improve the color quality of dried banana slices and obtain the best color protecting method, the effects of five different colors protecting agents, i.e. phytic acid, ascorbic acid, sodium chloride, EDTA and citric acid, on the color quality of dried banana slices evaluating were studied, by detecting the L^* value and browning degree. The results showed that the order of the effects was phytic acid > citric acid > EDTA > sodium chloride > ascorbic acid. Moreover, it was also found that a better color quality of dried banana slices could be obtained through soking the slices in the color fixative compound, containing 0.9% phytic acid and 0.3% citric acid, for 20 min, obtaining a 65.93 L^* value and an 84.4% browning inhibition rate.
