Abstract

This study aimed to determine the effect of leaf position and drying time on the chemical characteristics of gambier leaf-based green tea. The research was conducted at the Laboratory of Chemistry and Processing of Agricultural Products, Departement of Agricutural Technology, Faculty of Agriculture, Sriwijaya University from May 2024 to June 2024. This study used a Factorial Completely Rendomazied Design (FCRD) with two treatment factors. The treatment was repeated three times. The first factor is the position of gambier leaves (A1: young gamier leaves (1st and 2nd leaves ), A2: medium gambier leaves (3rd and 4th leaves) A3: old gambier leaves (5th and 6th leaves)) and the second factor is drying time (B1: 90 minutes, B2: 120 minutes, B3: 150 minutes). The parameters observed included chemical characteristics namely moisture content, ash content, total phenolics, antioxidant activity and pH test. A3B1 treatment (old gambier leaves (5th and 6th leaves)) with drying of 90 minutes) based on moisture content of 7,9%; ash content of 2,12%; solution pH of 4,56; total phenolics of 77,98 mgGEA/g; antioxidant activity (IC50) of 30,75 ppm.
