Astaxanthin microcapsule embedding process

The invention relates to an astaxanthin microcapsule embedding process. The process comprises the following operation steps: S1, selection of water-phase wall materials and oil-phase contents; S2, mixing: performing mixing according to a proportion; S3, high-pressure ultrasonic treatment and homogenizing emulsification: performing high-speed shearing, high-speed convection impact and high-frequency oscillation on a mixture through a high-pressure ultrasonic homogenizing cavity, and enabling molecular bonds of a water phase and an oil phase of astaxanthin oil to be tightly combined to form uniform mixed liquid drops under the action of a surfactant; S4, embedding, granulating and drying: forming water-phase cavity bubbles among the mixed liquid drops, and carrying out spray instantaneous drying to form an oil-in-water O/W astaxanthin microcapsule powder; S5, receiving detection in a clean area; and S6, sub-packaging and warehousing. According to the astaxanthin microcapsule embedding technology and process, th
