In order to study the aroma characteristics of the broken black tea from main producing countries, we selected nine kinds of broken black tea including Sri Lankan Uva black tea BOP, Sri Lankan black tea BOPF, Kenya PF1, Kenya BMF, Indonesia BOPF, Indonesia FANN, Indonesia PD, India Assam BOPSM and India Assam OF to analyze the aroma characteristics of each sample using SDE-GCMS hyphenated technique by detecting the aroma compounds. The results showed that the aroma compounds in the nine cultivars were similar, which were mainly composed of hydrocarbons, alcohols, aldehydes, ketones, ester, acids and the mixed oxide compounds. However, the ratio of each aroma compound was quite different in which E-2-hexenal, phenylacetal- dehyde, linalool, methyl salicylate, hexanal, beta-ionone, E,E-2, 4-heptadienal, benzaldehyde, 6,10,14- trimethyl- 2-pentadecanone and β-cyclocitral contents were high and formed the major aroma compounds.
