“colorant compositions, compounds, polymer, process of preparing a colorant composition, method of imparting blue color to a substrate, food products, medical device, pharmaceutical or nutraceuticals, cosmetic product and methods of preparing a colorant composition” The present invention relates to coloring compounds and methods of isolating coloring compounds derived from a reaction of genipin and an amine. dye compositions comprise purified compounds (for example, a purified polymer or a purified dimer) obtained from multiple fractionation through chromatography of the material resulting from the reaction. the purified polymer or dimer can be used as a colorant, alone or in combination with another colorant to impart color to a food, a drug, a cosmetic, a medical device, and textile products. |
