Comparative study on the extraction rate of rutin in sophora japonica tea with different processes
This study used UV spectrophotometry to determine the content of rutin in 12 types of Huaimi tea brewing solutions,and studied the effects of different production processes on the dissolution rate of rutin in Huaimi tea brewing.The results showed that after 5 rounds of brewing,the total dissolution rate of rutin in 12 types of Huaimi tea ranged from 4.06％to 13.13％.Different production processes have a significant impact on the brewing and dissolution rate of rutin in Huaimi tea.The overall dissolution rate of rutin from high to low is as follows:fumigation for 10 minutes,sun drying,microwave low heat mode treatment for 10 minutes;fu-migation for 10 minutes,sun drying,and frying;crushing and damaging the structure of locust rice,stir frying over high heat for 4 minutes,followed by drying and yellowing;direct drying at 90 ℃.
