Production method of resveratrol microcapsules

The invention discloses a production method of resveratrol microcapsules. The production method of the resveratrol microcapsules comprises the following steps: conducting separation and purification on porphyra haitanensis polysaccharides by means of a cellulose DE-52 ion exchange chromatography column and a glucan Sephadex G-100 gel chromatography column to obtain a purified porphyra haitanensispolysaccharide component PHP2; adding an ethanol solution of resveratrol into a balanced OVA solution for ultrasonic treatment, then conducting rotary evaporation to remove ethanol, and then adding abalanced PHP2 solution to form a compound solution; conducting magnetic stirring after the compound solution is heated, conducting oscillation after a pH value is adjusted to be 3-4, and conducting balancing; and conducting centrifugation, and washing and drying sediment obtained from centrifugation to obtain the resveratrol microcapsules. By adopting the method, not only can the water solubilityof the resveratrol be impro
