Title: Study on the Characteristic Aroma Components of Yunnan Black Tea
Abstract: The aroma components of 38 Yunnan black tea samples were extracted by Simultaneous Distillation and Extraction(SDE) and determined by Gas Chromatography Mass Spectrometry(GC-MS). The aroma composition and the differences of aroma constituents between CTC and Congou black tea samples were investigated. Results showed that similar aroma compounds were found both in Yunnan congou black tea and CTC black tea, but there contents varied a lot. A total of 97 aromatic compounds were found in the samples, including alcohols, aldehydes, acids, ketones, esters, lactones, nitrogenous and alkenes. Among the 23 pontent aroma compounds, the levels of alcohols was highest then the followed by aldehydes.
