Abstract

In this research, the effect of temperature, time, and stirring speed on the black tea extraction process was conducted. he temperature used in this study is 60°C – 700 C. While the time span used is around 10-30 minutes with a time difference of 30 seconds. And with a stirring speed of 100 rpm, the extraction results obtained 9 levels of tannins. The highest tannin content was obtained from extraction with a temperature of 75° C, 7 minutes of time, and stirring speed of 430 rpm. From the best tannin content, re-tested using a uv-visspectrophotometer. And the largest absorbance value was 0.381 with a tannin content of 582.4%.
