Abstract

Gaharu leaf tea can be developed as an alternative for tea drinking which is rich in antioxidants. This study aims to detect the antioxidants activity and to test the consumer preference to gaharu leaf tea (Aquilaria malaccensis Lamk) based on drying method. The drying method of gaharu leaves was conducted by using three methods, and they are heated at 40 0 C in an oven, roasted and dried under direct sunlight. Then, extract of the leaves in water was tested for the antioxidant activity by 2,2-Diphenyl-1-picrylhydrazyl (DPPH) method. The hedonic test of gaharu leaf tea was performed to determine the consumer preference. The extraction of this leaf showed antioxidants activities with IC 50 values accounted for 33,913 μg/ml with the oven drying at 40 0 C, 25,544 μg/ml with roasted, and 32,158 μg/ml under direct sunlight drying. The preference level based of consumption based on hedonic test of drying methods on 3-4 scale in moderately favorable. Although the oven drying method was preferably, the roasted drying method had very strong antioxidant activity despite of the oven drying method.
