Deodorized high-purity algal polysaccharide microcapsule as well as preparation method and application thereof

The invention belongs to the technical field of algal polysaccharide extraction, and particularly relates to a deodorized high-purity algal polysaccharide microcapsule as well as a preparation method and application thereof. The preparation method comprises the steps: firstly, deodorizing a seaweed raw material, then extracting, separating and purifying the seaweed polysaccharide by combining a continuous phase change extraction technology with a water extraction and alcohol precipitation method, and then preparing the seaweed polysaccharide microcapsule in a spray drying manner. According to the preparation method, the deodorizing effect can be achieved, the sensory quality of the seaweed product is improved, the extraction rate and yield of the seaweed polysaccharide can be effectively improved, the damage to bioactive components is small, and no harmful solvent is left. The method is simple in process flow, easy to operate and suitable for large-scale industrial production. 本发明属于海藻多糖提取的技术领域，尤其涉及一种去腥高纯的海藻多糖
