黑曲霉发酵对咖啡碱代谢的影响
Influence of Aspergillus niger Fermentation on Caffeine Metabolism
摘要
Abstract
The essence of pu-erh tea solid-fermentation process is microbial metabolism , and Aspergillus niger is a dominant fungus in the metabolism and has a huge impact on caffeine metabolism .In this study, Aspergillus niger strains were inoculated into tea, tea infusion, and liquid medium containing caffeine , then the content of purine base at different stages of fermentation was de -termined .The results showed that Aspergillus niger had grater effect on theophylline than on theobromine , and greater effect on theo-bromine than on caffeine .In addition , during the liquid -fermentation of pure caffeine , theophylline content increased to a maxi-mum extent , and it was positively correlated with caffeine concentration .关键词
