EKSTRAKSI ZAT WARNA DARI KULIT MANGGIS

Abstract

Dyes have long been used in food and beverages to improve the appearance of food products. At first, the dyes used are natural dyes from plants and animals. One of the plants that can be used as a dyes source is mangosteen, where the dyes comes from the skin of the mangosteen fruit. There are several methods of extraction for mangosteen skin extract. One of them soxlhetation. Soxlhetation is an immersion method of sample extraction with repeated continuously over time, where the solvent was evaporated and condensed to immers the sample. The purpose of this study was to determine and study the optimum solvent and the optimum time for mangosteen skin extract of soxlhetation method and calculate the yield of mangosteen peel extract. Solvents used 96% ethanol, 96% methanol and ethyl acetate with a variety of 3, 4, and 5 hours for each solvent. Of the three solvents, the highest yield obtained in the solvent methanol and the optimum time was 4 hours. The highest yield was 14.67%.
