| Abstract: | The analysis method of the minor volatile perfume constituents in beer using capillary gas chromatography was introduced. The twelve minor volatile perfume constituents were quanlitatively and quantitatively analyaed by the method, in which the automatic headspace sampling technique was used and high pure nitrogen gas (99.999%) was used as carrier gas. The results showed that the variation coefficient of the perfume constituents were less than 5% except aldehyde and ethyl caprylate, and the percent recovery were more than 90%. The good repeatability and accuracy were got. |
