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 capsicum red pigment, in particular to a method for improving the color value of capsicum red pigment. Background technique [0002] Capsanthin is a dark red paste-like liquid. Its main components include capsanthin, capsanthin, zeaxanthin and carotene. It is a class of fat-soluble tetraterpenoids extracted from the Solanaceae plant pepper. It It is not only strong in coloring power, 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 capsanthin with spicy flavor from dried red pepper with organic solvent, and then to produce capsanthin finished product through the process of removing hotness and residue. The total yield of the pigment is high, but the color value of the product is low, and the impurity content is high. After the pigment is stored for a...
