Abstract

This research aimed to determine the physical, chemical and sensory of rosella flower tea and lemongrass as functional beverages. This research used a Non-Factorial Completely Randomized Design (RAL) with six factors and the treatment was repeated 3 times. The treatment factors include the addition of lemongrass (20% (b/b), 40% (b/b), 60% (b/b), 80% (b/b), 100% (b/b) and 120% (b/b)). The parameters observed included physical characteristic (color), chemical characteristic (pH, antioxidant activity and test of flavonoid compounds) and sensory tests (color, taste and aroma). The result showed that the addition of lemongrass to rosella flower tea significantly affected the color (lightness (L*), redness (a*), yellowness (b*)), pH, antioxidant activity, flavonoid compounds and sensory tests (taste and aroma). Functional beverage from rosella flower tea with the addition of 60% (b/b) lemongrass is the best treatment based on sensory tests (color 3,0; taste 3,2; aroma 3,16) with physical characteristics color lightness (L*) 29,15; redness (a*) 7,87; yellowness (b*) 5,35 and chemical characteristic pH 2,92 and antioxidant activity 65,45 ppm.
