20140350127 | COLORANT COMPOUNDS DERIVED FROM GENIPIN OR GENIPIN CONTAINING MATERIALS - The present disclosure provides colorant compounds and methods of isolation of the colorant compounds derived from a reaction of genipin and an amine. The colorant compositions comprise purified compounds (e.g., a purified polymer or a purified dimer) obtained from multiple fractioning by chromatography of the reaction resulting material. The purified polymer or dimer can be used as a colorant by itself or in combination with another colorant for imparting color to a food, a drug, a cosmetic, a medical device, and textile products. | 11-27-2014 |
