摘  要:
为探明乳酸菌发酵对武夷岩茶主要功能成分的的影响,试验采用超声波辅助萃取和适宜的乳酸菌发酵技术,制备岩茶萃取液和岩茶发酵液,通过HPLC定量分析研究乳酸菌发酵前后武夷岩茶中咖啡因的变化。结果表明,当接种量为6.8×103CFU/mL,乳酸菌发酵岩茶中咖啡因含量最高达到16.76 mg/g,随着乳酸菌接种量的继续增加,咖啡因含量下降趋势不明显,进行螯合FEC的能力评价结果表明武夷岩茶具有较高的抗氧化活性。

摘  要:
In order to study effects of lactic acid bacteria fermentation on the main components of Wuyi rock tea, the caffeine content of Wuyi rock tea before and after the change of lactic acid bacteria fermentation was analyzed. The results showed that at 37 ℃ fermentation temperature, fermentation time was 48 h, the inoculation amount was 6.8×103CFU / mL,the content of gallic acid in lactic acid bacteria fermentation liquid tea reached the highest of 16.76 mg / g, indicating that the fermentation of lactic acid bacteria had a certain influence on the content of gallic acid in tea. With the increase of the the fermentation of lactic acid bacteria, the caffeine content had an unobvious down-trend. The chelation ability of FEC was evaluated and the result showed that Wuyi rock tea had a high antioxidant effect.
