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. ...
