The aroma components of Bran Rice-Green Tea were analyzed and identified by GC and GC-MS. A total of 50 aroma compounds were identified in all samples. Main components in the aroma compounds of Bran Rice-Green Tea samples were pyrazines and furfuryl alcohol, geraniol, benzyl alcohol and indole. The composition differences of major aroma compounds of the Bran Rice-Green Tea by content rate of Bran Rice-Green Tea were also compared. The patterns of Bran Rice-Green Tea samples by content rate of Bran Rice and Green Tea were similar. But the aroma amounts of pyrazines and furfuryl alcohol having roast and nutty aroma, geraniol having rose floral aroma and benzyl alcohol having sweet and fruity aroma were different significantly by content rate of Bran Rice-Green Tea. As a result, geraniol, benzyl alcohol and pyrazines seem to be important contributors to the characteristic aroma compounds of the Bran Rice-Green Tea.
