Abstract

Nanda Mahashil, Effect Of Using Stevia Leaves (Stevia Rebaudiana Bertoni) On Chemical, Physical, Functional And Characteristics Organoleptics Of Green Tea Leaves Gambir (Uncaria Gambir Roxb.) (Supervised by Budi Santoso).Gambir leaves have the potential to be a basic ingredient for green tea. This innovation is expected to increase the utilization and economic value of gambir leaves. The addition of stevia leaves is used as a healthier natural sweetener. The aim of this research is to determine the effect of using stevia leaves on the chemical, physical, functional and organoleptic characteristics of gambier leaf green tea. This research used a Non-Factoral Completely Randomized Design (CRD) with treatment formulation (F), namely gambier leaves and stevia leaves consisting of 5 treatment levels (0%, 10%, 15%, 20%, 25%, and 30%) where each treatment was carried out 3 times. The parameters observed in this study were antioxidant activity (IC50), ash content, water content, total phenol, organoleptic test (hedonic test), ranking test, and color. The research results showed that the addition of stevia leaves had a significant effect on organoleptic tests (aroma, color and taste), ranking tests, ash content, total phenols and antioxidant activity. However, there is no significant effect on the water content and color of L*, a*, b*. The best treatment was treatment F4 (25% stevia leaves) based on organoleptic (aroma, color, and taste), chemical, and functional preference tests, because it gave the most optimal results overall.
