Problems solved by technology

The open document "Encapsulation of anastaxanthin-containing lipid extract from shrimp waste by complex coacervation using a novel gelatine cashew gum complex" reports that gelatin and cashew gum complexes are used as wall materials to improve the solubility of astaxanthin by complex coacervation method, but this The solubility of the astaxanthin product obtained by the preparation method is only 28.6%, and the water solubility of astaxanthin is low
The public document "Potato protein-based carriers for enhancing bioavailability of astaxanthin" reports that potato protein is used as a carrier to improve the solubility of astaxanthin, but this preparation method requires dialysis of the potato protein solution for a week, which takes a long time and the production process is complicated

Abstract

The invention discloses a water-soluble astaxanthin product and a preparation method thereof. The water-soluble astaxanthin product comprises astaxanthin, whey protein and ethyl cellulose, the contentof the astaxanthin is higher than 60%, and particle size of the product is micron-size. The preparation method comprises following steps: an astaxanthin alcoholic solution, an ethyl cellulose alcoholic solution and a whey solution are subjected to batch mixing in certain proportion, homogenizing emulsification, secondary emulsification, low-temperature settling, filtering, low-temperature vacuumevaporation and spray freeze drying, and the water-soluble astaxanthin is prepared. According to the invention, water solubility and stability of the astaxanthin are effectively improved, the applicable range of the astaxanthin is expanded, and the product is widely applicable to multiple fields of food, healthcare products, medicine and the like.

Description

technical field [0001] The invention relates to the technical field of water-soluble marine nutrients, in particular to a water-soluble astaxanthin product and a preparation method thereof. Background technique [0002] Astaxanthin (3,3′-dihydroxy-4,4′-diketo-β,β′-carotene) is a fat-soluble carotenoid pigment with a molecular formula of C40H52O4 and a relative molecular mass of 596.86, insoluble in water , Soluble in most organic solvents such as ethanol, acetone, ether and chloroform. Astaxanthin is mainly found in microalgae, yeast, trout, krill, shrimp and crayfish, and Haematococcus pluvialis is a rich source of natural astaxanthin, the content of astaxanthin is as high as 6% of dry matter, and it is Think of it as a "concentrate" of natural astaxanthin. [0003] Natural astaxanthin is an effective strong antioxidant, which has strong anti-oxidation properties and can effectively scavenge free radicals in the body to prevent oxidative damage to tissues, cells and DNA. ...
