Abstract

The utilization of natural resources that contain antioxidants is in high demand by the community to prevent degenerative diseases such as heart disease, diabetes, stroke and cancer. Processing of Dayak onion and beet root in the form of herbal tea has great potential to be used as a functional drink because both of these plants contain flavonoids which have antioxidant properties. In 5 tea formulas made by comparing the composition of Dayak onions and beet root, a preference test was conducted on several panelists related to color, aroma and taste and obtained 3 formulas favored by the panelists are formula1, 3 and 4. the purpose of this study was to determine the total flavonoid levels of each of the teabag formulas favored by panelists using the UV Visible spectroprotometry method with a quercetin comparison. From the research conducted obtained linear regression equation data y = 0.0364x + 0.0028 with r = 0.997. Total flavonoid levels for each teabag combination of dayak onion and beet root for formula 1; formula 3; formula 4 is 0.9309%; 0.975% and 1.841%, where the highest total flavonoid content is formula 4, which is 1, 841%.
