Problems solved by technology

The lye treatment process is complicated, the product yield is low, and it is difficult to obtain a high-purity product; the silica gel column chromatography consumes a large amount of mobile phase, the silica gel cannot be regenerated, and the production cost is high, which is not suitable for large-scale industrial production; macroporous adsorption Resin method can get high-purity capsaicinoids, but the yield is low
Supercritical CO 2 Fluid extraction has a good separation effect on capsanthin, but the technical investment is relatively large, the equipment requirements are high, and it is difficult to achieve large-scale industrial production
And the current reports on these separation methods are only for the separation and purification of capsaicinoids or capsanthin in capsicum oleoresin

Abstract

The invention relates to the field of separation and purification of capsaicin and paprika red pigment, and particularly discloses a method for preparing paprika red pigment and a capsaicin material. According to the method, capsicum oleoresin is subjected to three-level molecular distillation to respectively obtain the capsaicin material and the paprika red pigment, wherein the total content of capsaicin and dihydrocapsaicin in the capsaicin material is greater than 70%, and the color value of the paprika red pigment is higher than 200. The capsaicin material is recrystallized and purified, the total content of capsaicin and dihydrocapsaicin in crystallization is more than 85%, further capsaicin crystals and dihydrocapsaicin crystals are obtained through preparation and separation of high performance liquid chromatography, and the content of each of the capsaicin crystals and the dihydrocapsaicin crystals is more than 95%. The method is simple and convenient to operate and low in production cost, has a good separation effect and is suitable for industrial production; and the content of the products is high.

Description

[0001] Technical field [0002] The invention involves the separation and purification field of chiliine and chili red pigment, and more specific, it involves a kind of pepper [0003] Preparation methods of redine and chiloine -based substances. Background technique [0004] Pepper is the eggplant plant pepper Capsicum annuum L. The dry and mature fruits of cultivation variants are also used by their stems and roots. It is a year -old herbaceous plant with homologous medicines and foods. It has a long history as a seasoning agent in my country.Pepper oil resin is a dark red viscous oil-shaped liquid extracted and concentrated from the pepper. It is a mixture of a variety of substances. It mainly contains chiliine substances, chilius, chilius, β-carotene, etc. [0005] Pepper -alkaline substances are spicy substances for pepper, which are mixtures such as chiliine, high dihydrogen chiloids, dihydrous chiliine, glycolic podamine, cubic podamine, etc.Best.Pepper -alkali substances ...
