From the observation, it was found that the most suitable processing techniques to extend shelf -- life of longan were crunchy longan pickle, longan dried salted pickle and dried longan since these three types of methods can extend the shelf —life of longan for about two months. For the packaging methodologies, all types of packaging were suitable to use for crunchy longan pickle, longan dried salted pickle and dried pickle since there were no significance difference occur between the usage of all four types of packaging besides for longan pickle and longan syrup.
