摘  要:
The aroma of green tea liquid was studied by using headspace absorption method (HAS method) and tea liquid absorption method (TLA method) with XAD-2 rein. The results show that the essential oil made by HAS method has tea flavor but that made by TLA method has a little difference compared with tea flavor. There are some differences in compounds between the two; the rate of reflection is 54.17% during the same TR. Linalool oxides and its isomeric materials are not found by using TLA method, but some other materials are found.
