These pigments are among the best natural pigments to be used in food industry. In this study, the method for extraction of cherry’s pigment (Anthocyanin) using an Amberlite XAD-7 resin is discussed. Amberlite XAD-7 has got an excellent condition for extraction of Anthocyanin due to its lack of charged groups and great porosity. After completion of adsorption process of Anthocyanin on Amberlite resin, desorption process was performed by acidic methanol which was able to extract about 90 percent of Anthocyanin compounds. Furthermore, Langmuir and Freundlich isotherms were applied for explanation of Anthocyanin adsorption which finally indicated that Langmuir model has a better consistency Anthocyanin is known as natural pigments of fruits.
