KOEFISIEN TRANSFER MASSA PADA EKSTRAKSI ANTOSIANIN DARI BUNGA DADAP MERAH

Anthocyanins are pigments which give most fruits and flowers red, blue, andviolet color. The sourceof anthocyanins is red dadap flowers. Anthocyanins dyes can be used as food additives. These dyes do not cause damage to food stuffs and they are not substance toxic to the body. Taking anthocyanins pigments of red dadap flowers was carried out by extraction. Batch extraction was performed in a threeneck flask equipped with a stirrer, thermometer, cooler, and water bath. This extractions used ethanol solution-hydrochloric acid mixture and ethanol-technical-citric acid mixture as a solvent. The extraction of 10 g red dadap flowers C. This aim of this study was to evaluate the extraction of anthocyanins dyes of red dadap flowers and to determine the mass transfer coefficients. The variable that was evaluated was extraction time. Batch extraction that used 100 mL of ethanol l
