Abstract

This study aims to determine the effect of the ratio of ingredients to solvents and extraction time of maceration method on the characteristics of anthocyanin extract of senduduk fruit. This research was conducted from June 2023 to December 2024 at the Laboratory of Agricultural Product Chemistry, Department of Agricultural Product Technology, Faculty of Agriculture, Sriwijaya University. This study used a Randomized Group Factorial Design (RAKF) with 2 treatment factors and each treatment was repeated 3 times. Treatment factor A was the ratio of ingredients and solvent (1:2, 1:4, 1:6) and treatment factor B was extraction time (24 hours, 48 hours, 72 hours). Parameters observed in this study include yield, pH, color (lightness, redness, yellowness) and antioxidant activity. The results showed that treatment factor A (ratio of ingredients and solvent) and treatment factor B (extraction time) significantly influenced the yield, pH, color (lightness, redness, yellowness) and anthocyanin extract activity of senduduk fruit. The best treatment in this study is the ratio of ingredients and solvents 1: 6 and extraction time for 72 hours based on yield of 59,91%, extract pH of 2,58, lightness of 19,49%, redness of 8,46, yellowness of 5,45, and antioxidant activity (IC50) of 87,44 (ppm). the results also showed that anthocyanins are not heat stable
