Problems solved by technology

[0004] There are many ways to improve the light absorption ratio of capsanthin commonly used at present, but each has disadvantages, such as the acid-alkali treatment method has cumbersome steps and low production efficiency, the solvent extraction method has low pigment separation and many impurities, supercritical CO 2 The cost of fluid extraction is high, and silica gel column chromatography is difficult to produce on a large scale
The patent "a method for preparing capsanthin with high light absorption ratio" (CN104830096A) discloses a method for separating and preparing capsanthin in capsanthin by column chromatography, and using an adsorbent to absorb the capsanthin in capsanthin. Gradient elution is performed after each component to obtain components with higher purity. The prepared capsanthin has a high absorbance ratio, but the product has high viscosity, poor fluidity, and poor oxidation resistance. The wavelength is 210-440nm, especially 285nm ultraviolet light Can make it fade, can not be directly applied with the terminal
The patent "a method for increasing capsanthin content and light absorption ratio" (CN106497138A) discloses a method of statically adsorbing capsanthin solution using any one of the adsorbent silica gel, alumina, cellulose or polyamide to increase the capsanthin concentration. The method of red pigment content and absorbance ratio, the capsanthin with high content and high absorbance ratio is a mixture of capsanthin and capsanthin, and the complete separation of red and yellow components cannot be realized. The obtained product has the same defects: high viscosity, poor fluidity, and poor oxidation resistance, is not easy to preserve, and cannot be directly used in the terminal

Abstract

The invention relates to a preparation method of capsorubin with a high light absorption ratio and capsorubin with a high content, belongs to the technical field of biological separation, and adopts astatic adsorption method to adsorb capsorubin in capsorubin through activated clay so as to realize separation of capsorubin from other components. The capsorubin with high light absorption ratio andthe capsorubin with high content are obtained in sequence. The capsorubin with high light absorption ratio prepared by the invention contains yellow protective components such as beta-carotene, zeaxanthin and the like with strong oxidation resistance, is high in oxidation resistance, good in stability, low in viscosity and good in flowability, can be directly applied to terminal production without adding other substances for blending, and can obtain high-content capsorubin at the same time; the method is simple to operate, the static adsorption method adopts a quantitative adsorbent and a quantitative dissolving solution, adsorption equilibrium is achieved through full contact, effective separation of components can be achieved in a short time, and large-scale production is facilitated.

Description

technical field [0001] The invention relates to a preparation method of capsanthin with high light absorption ratio and high content of capsanthin, which belongs to the technical field of biological separation. Background technique [0002] Capsanthin is one of the hotspots of natural pigment research, and it is a mixed pigment containing multiple pigment components. At present, capsanthin products are mainly capsanthin, which belongs to polyketenes in carotenoids, and mainly includes red components with high polarity and yellow components with low polarity. Capsanthin, the main components of the yellow component are carotene and zeaxanthin. Among them, the main coloring components of capsanthin are capsanthin and capsanthin, which are bright in color, have significant effects in coloring strength and color retention, are safe and non-toxic, and can be absorbed by the human body, so they are widely used in food , health products, medicine, cosmetics and other fields.
