titleOfInvention | Method for refining gardenia yellow pigment by adopting solvent crystallization |
abstract | The invention provides a method for refining a gardenia yellow pigment by adopting solvent crystallization, belonging to the field of plant extraction. The method comprises the following steps of: adding a solvent A into a gardenia yellow pigment crude product, stirring at 10 to 30 DEG C to dissolve the gardenia yellow pigment crude product or heating to 35 to 100 DEG C to dissolve the gardenia yellow pigment crude product, and filtering and taking filtrate, wherein the solvent A consists of 70 to 100 percent of a hydrophilic organic solvent and 0 to 30 percent of water; and crystallizing the filtrate, and drying to obtain the gardenia yellow pigment. According to the gardenia yellow pigment prepared by the method, the color value is more than 200, and the A238/A440 and A325/A440 are smaller than 0.2. The gardenia yellow pigment prepared by the method is applied to preparation of foods, healthcare foods, cosmetics, pharmaceutical compositions and saffron monomer compounds. |
