Isolasi Senyawa Flavonoid dari Limbah Kulit Buah Kakao dengan Variabel Mesh Partikel dan Suhu Evaporasi
Abstract
The utilization of waste of cocoa skin has not been optimum; the waste is usually left to degrade in the soil. The cocoa skin is known to contain polyphenol and flavonoide. This work investigated the isolation of flavonoide from the waste of cocoa skin using maseration extraction method with a solvent of methanol. The independent variables studied were the particle size of cocoa skin (70, 80 mesh) and the temperature of solvent evaporation (50, 60oC) with a dependent variable of percentage of total isolated flavonoide. The results show that the smaller particle size and the higher temperature of solvent evaporation are, the higher the percentage of total isolated flavonoide. For the particle size of 80 mesh and the temperature of solvent evaporation of 60oC, the percentage of total isolated flavonoid are 1.304% and 1.194%, respectively.
