Ekstraksi Pigmen Antosianin dari Kulit Rambutan (Nephelium Lappaceum) dengan Pelarut Metanol

Abstract

Rambutan fruits (Nephelium lappaceum Linn) is a kind of tropical fruits which come from Malaysia and Indonesia. Their red coloured rinds have not used yet effectively and the red coloured may be due to anthocyanin that can be used for natural colours. The purpose of this research is to know the optimal condition of the extraction of anthocyanin, that is particle size of rambutan‟s rinds, temperature and extraction time. Analysis of the anthocyanin use spectrophotometer UV-Vis to detect the wavelength and the absorbance of the anthocyanin. The best condition is rambutan‟s rind milled by blender at temperature 50 0C and extraction time for 6 hours. Those give the highest color intensity having maximal absorbancy of 1,6103, anthocyanin concentration of 55,7659 mg/L and rendement of 0,2788%.
