连翘叶黄芪发酵茶制备工艺优化及其抗氧化活性研究
Study on optimization of preparation technology of Forsythia suspense leaves and Astragalus membranaceus fermented tea and its antioxidant activity
摘要
Abstract
The aim of this study was to prepare the fermented tea by compound strain for relieving the bitter and cold properties of Forsythia suspense leaves,Forsythia suspensa leaves and Astragalus membranaceus were used as main raw materials and Lactobacillus bulgaricus and Lactobacillus plantarum were used as fermentation strains,high performance liquid chromatography was used to determine the contents of chlorogenic acid,rutin,forsythia suspensa glycoside A,Forsythia suspensa glycoside,and forsythia suspensa lipin in Forsythia suspensa leaves and Forsythia suspensa fermen-ted tea,The content of the five components and in vitro antioxidant activity were compared,The re-sults showed that the optimum preparation conditions of Forsythiasuspensa fermented tea were 15 g Forsythia suspensa leaves,2.4 g Astragalus membranaceus,and the bacterial strain accounted for 3.9％of the total mass,and then Lactobacillus bulgaricus and Lactobacillus plantarum accounted for 55％and 45％of the bacterial strains,respectively,Compared with Forsythia suspensa leaves,the contents of chlorogenic acid,rutin,Forsythia suspensa glycoside A and Forsythin in Forsythia suspensa fermented tea were lower and the Forsythiaside content was higher,The results of antioxi-dant activity showed that the scavenging rates of DPPH radical were 76.74％and 80.24％at the concentration of 8 mg/mL,respectively,This study provides a new way to alleviate the bitter and cold properties of Forsythia suspensa,and provides a theoretical basis for the utilization of Forsythia suspensa resources and the development of fermentation products.关键词
