摘　　要：为开发桂花铁观音新产品,以中低档清香型铁观音和桂花鲜花为原料,对其窨花前后感官品质与化学成分进行分析。结果表明:处理A5感官综合得分最高为92.77,品质表现为桂花香浓郁,滋味鲜醇甘爽、桂花香明显;最佳窨制工艺为配花量(桂花鲜花:铁观音)1∶10、窨制2次、每次窨制15 h;与茶坯相比,桂花铁观音的叶绿素、茶多酚、酚氨比、咖啡碱含量均有所下降,而水浸出物、氨基酸、可溶性糖、茶黄素、茶红素和茶褐素等的含量均有所增加,且处理间差异显著(p<0.05)。窨制工艺提升了花香和滋味的鲜爽感,表明窨制工艺有利于提升中低档铁观音的品质。In order to develop new products of Osmanthus Tieguanyin, the sensory quality and chemical composition of sweet-scented Osmanthus Tieguanyin before and after scenting were analyzed in this study by low and middle grade sweet-scented Tieguanyin and Osmanthus flowers as materials. The results showed that the sensory comprehensive score of A5treatment was the highest with 92.77, and the quality of sweet-scented Osmanthus Tieguanyin was characterized by strong and obvious fragrance, fresh and mellow taste. The best scenting process is the amount of flowers(Osmanthus flowers: Tieguanyin)1:10, scenting 2 times, each scenting time is 15h;compared with Tieguanyin without scenting, the chlorophyll, teapolyphenol,polyphenol ammonia ratio, caffeine content of sweet-scented Osmanthus Tieguanyin decreased, and the water extract, amino acid, soluble sugar, TFs, TRs and TBs content increased, and there were significant differences(p<0.05) between different processing. Scenting process improved the aroma and taste, indicating that it was beneficial to improve the quality of low and middle grade Tieguanyin.
