A substance containing natural astaxanthin is used as a microcapsule core material, and a primary embedding wall material is used for primary embedding of the microcapsule core material to obtain Primary embedding material, the secondary embedding material is used for secondary embedding to obtain natural astaxanthin microcapsules； the microcapsule core material includes vitamins, lecithin, natural astaxanthin And olive oil, the primary embedded wall material includes sorbitan fatty acid ester, whey protein solution and gelatin solution； the secondary embedded wall material includes maltodextrin solution and sucrose fatty acid ester solution. The natural astaxanthin microcapsules prepared by the present invention are prepared from double-layered wall materials astaxanthin microcapsules. The microcapsules have good stability and water solubility, are beneficial to human body absorption, and maintain the stability of astaxanthin.
