普洱茶中丙烯酰胺含量检测与生成机理研究
Survey of Acrylamide Contents in Pu-erh Tea and Study on Its Formation Mechanism
摘要
Abstract
Fifty Pu-erh tea samples were investigated for acrylamide ( AA) contents. The results showed that the AA contents in tea samples were generally low, 2. 05 ~91. 95 ng/g. Based on the correlation analysis between sugar contents and the amount of AA, it was found there was the highest correlation coefficient between the sucrose content and AA ( R2 =0. 577 6 ) , followed by fructose (R2 =0. 497 7 ) , glucose was the least ( R =0.256 7). The asparagine contents of wet-stored Pu-erh tea samples could not detected. In combination with literature records, it could be concluded that AA mainly generated through acrolein way during the fermentation of Pu-erh tea. There was a very small contribution of asparagine way.关键词
