Abstract

The invention discloses a method for increasing color value of capsicum haematochrome. The method is as below: first dissolving capsicum haematochrome with acetone; adding a sodium hydroxide aqueous solution for saponification; then removing the slag and concentrating; dissolving the capsicum haematochrome obtained from concentration with 6# solvent naphtha; washing the mixture with brine; and finally concentrating to obtain refined capsicum haematochrome. The method first utilizes saponification to remove residual grease in capsicum haematochrome, then employs brine washing to remove other impurities in the capsicum haematochrome, so as to refine the capsicum haematochrome and increase purity and color interval of the capsicum haematochrome. The method can thoroughly remove impurity components in the capsicum haematochrome, so as to obviously improve quality of the capsicum haematochrome. After long term dispose, the capsicum haematochrome does not occur micelle deposition; and capsicum haematochrome stored at low temperature still has good fluidity, and has color value increased by 2-3 times and color value yield higher than 95%.

Description

technical field [0001] The invention relates to a method for refining capsanthin, in particular to a method for increasing the color value of capsanthin. Background technique [0002] Capsanthin is a dark red paste liquid, the main components are capsanthin, capsanthin, zeaxanthin and carotene, etc. Not only has strong coloring power, is safe and non-toxic, but also has high nutritional value, and is widely used in food, medicine, cosmetics and other industries. [0003] The conventional production method of capsanthin is to first extract the crude product of capsanthin from dry red pepper with an organic solvent, and then produce the finished product of capsanthin through processes such as despicing and residue removal. The total pigment yield of this method is high, but the color price of the product is low, and the impurity content is high. After the pigment is placed for a long time, colloidal precipitation is prone to occur, and coagulation is prone to occur when the p...
