Abstract:To develop the optimal processing technology of Hedychium coronarium tea，a single factor and multi-level experimental design method was adopted，and the method of sensory evaluation was used to explore the method of processing Hedychium coronarium tea by oven drying，microwave drying and vacuum-freeze drying.The optimal processing techniques for each of the three methods were as follows：（1）for oven drying，picking"funnel"period or"butterfly-shaped"period flowers→retaining the complete corolla tube→placing the flowers vertically in the oven → drying at 70 ℃；（2）for microwave drying，picking"funnel"period flowers→ retaining the complete corolla tubes→ microwave de-enzyming at 6 kW，60℃ for 3 min，then drying at 2 kW，60℃ for 30 min；（3）for vacuum-freeze drying，picking"fully open"period flowers→ retaining the complete corolla tubes→pre-freezing at-23℃for 2 h，sublimation drying at-12℃for 15 h，then desorption drying at 5℃ for 18 h.Through sensory evaluation，the quality of Hedychium coronarium tea obtained by vacuum freeze-drying is the best.The color of the best Hedychium coronarium tea was yellowish and uniform，the flower shape was three-dimensional，the aroma was pure and fragrant，and the taste was fresh and refreshing.However，in terms of production cost，the oven drying method is more suitable for large-scale production.
