The invention provides a method for preparing water-soluble astaxanthin, which can realize natural astaxanthin and raw materials by mixing raw materials containing astaxanthin with a solution containing organic acid, and then performing cell crushing and then leaching. Naturally occurring proteins, nucleic acids or polysaccharides interact with each other to directly obtain water-soluble astaxanthin without modification of astaxanthin, and astaxanthin comes from natural sources. Low cost, green and safe, no organic solvent residue, easy to realize industrialization. |
