Abstract

The invention relates to a microcapsule of astaxanthin in haematococcus pluvialis by a foam spray drying method and a preparation method thereof, and belongs to the technical field of natural pigmentstability. The microcapsule is prepared from the following raw materials in parts by weight: 4 to 5g of arabic gum, 1 to 2g of modifiable starch, 3 to 6g of soyabean protein, 1 to 2g of lactitol, 8 to12g of astaxanthin and emulsifiers. After the astaxanthin is microencapsulated, the influence of environment factors such as light, heat and oxygen on the astaxanthin stability is avoided, so that the functionality of the astaxanthin is maintained; the storage period is prolonged. By the preparation method provided by the invention, the mass transfer rate is improved; the spray drying time is shortened. The surface of the prepared product is of a coarse, sunken and porous structure; the solubility and the dispersibility of the astaxanthin in water are improved; the dispersion stability is high. The process is simple; the production cost is low; the operation conditions are mild; the method is suitable for industrial production.

Description

technical field [0001] The invention relates to microencapsulation of astaxanthin in Haematococcus pluvialis prepared by a foam spray drying method and a preparation method thereof, belonging to the technical field of natural pigment stability. Background technique [0002] Astaxanthin A red carotenoid found in shrimp, crab, fish, certain algae, etc., chemical name is 3,3'-dihydroxy-4,4'-diketo-beta-carotene , is a fat-soluble red pigment, insoluble in water, easily soluble in organic solvents such as chloroform, acetone, benzene and carbon disulfide, and contains unsaturated compounds such as terpenes. Natural astaxanthin is the strongest natural antioxidant in the world. It can effectively remove oxygen free radicals in cells, which is 6,000 times that of vitamin C; 1,000 times that of vitamin E; 800 times that of coenzyme Q10; lycopene (lycopene) 1800 times that of carotol (lutein); 200 times the efficacy of carotol (lutein); therefore, it has various physiological funct...
