Problems solved by technology

[0005] Chinese Invention Patent Publication No. 101177540 discloses "a preparation method of food-grade lutein water-soluble dry powder", in order to prevent the total reaction of active ingredients in the production process To reduce the content of formula isomers, mix lutein crystals with low-boiling, volatile organic solvents that have high solubility for lutein crystals, heat and dissolve at a temperature below 100°C, then add water phase substances, and stir evenly , high-pressure homogenization and spray drying to obtain finished products. This method uses a large amount of organic solvents to easily cause solvent residues, and solvent recovery is difficult, which affects the quality of lutein

Abstract

The invention discloses a water soluble xanthophyll preparation technology. The technology comprises the following steps: adding marigold oil into a saponification tank, adding an alcohol compound into the saponification tank, heating until the temperature in the saponification tank rises to 75-90DEG C, continuously adding a strong alkaline solution into the saponification tank in a dropwise manner, and fully reacting to obtain nanometer xanthophyll crystals; diluting the nanometer xanthophyll crystals 2-8 times by 70-95DEG C deionized water, and adjusting the pH value to 4-7 by using an acid to obtain a diluted solution; and adding an organic solvent into the diluted solution according to a weight ratio of 1:1-1:3, and extracting 2-5 times to obtain purified xanthophylls. The marigold oil is processed through a special saponification technique to obtain the nanometer xanthophyll crystals, so the technology improves the quality of xanthophyll and increases the production yield of xanthophylls.

Description

technical field [0001] The invention relates to a preparation process of water-soluble lutein, which belongs to the technical field of extraction process. Background technique [0002] Lutein belongs to carotenoid, which is a kind of natural pigment. It has bright color, strong tinting power, good anti-oxidation, safe and non-toxic, and has rich nutritional value. It is a natural substance that widely exists in vegetables, flowers, fruits and certain algae plants, and is widely used in many fields such as food, health care products, cosmetics, medicine and animal and poultry feed. The U.S. Food and Drug Administration has approved lutein as a food supplement for use in food as early as 1995. The Ministry of Health of China has formulated a national standard for lutein in 2011 and approved it as a food coloring agent for use in food. Because lutein is widely used, 1g of lutein is equivalent to 1g of gold in the international market, so it has the reputation of "plant gold". ...
