Coatings can be a new method for cucumber preservation. Coating materials ware selected from galangal, forsythia, and gardenia. Galangal coating can reduce weight loss, retard the decrease of exudate levels and receive better sensory evaluation. Based on these findings, another two coating materials, propolis and chitosan, compared their effects with galangal. From one-dimensional analysis of variance multiple comparisons Duncan, galangal worked best in the way of sensory evaluation, and propolis coating provided active elements in the maintenance of exudate content. Chitosan coating retarded the decline of hardness and maintained soluble solids and Vc content. All in all, through comprehensive analysis of various indicators ,chitosan coating was better than galangal and prpolis.
