Abstract In this study, the Chenfragrance of Puerh tea was isolated and identified and the aroma extracts of Puerh tea were microencapsulated to expand its use. Aroma of Puerh tea was extracted by simultaneous distillation extraction (SDE) and analyzed using gas chromatography (GC) and gas chromatographymass spectrometry (GC/MS). The results showed that the main aroma components of Puerh tea were linool oxideⅠ, linool oxideⅡ, 1, 2, 3trimethoxybe, 3-hydroxy-2, 2, 6-trimethyl-6-vinyltetrahydropyran and so on. Meanwhile, the aroma extracts of Puerh tea were microencapsulated using (cyclodextrin and konjac glucomannan as the wall and core materia1s. The optimal technology of microencapsulation was that the ratio of the aroma extracts to the wall material was 1∶6, the ratio of βcy clodextrin to konjac gum was 500∶1, the concentration of soluble solid was 20% and the drying temperature was 25℃.
