天然虾青素作为一种新型的天然抗氧化剂，其抗氧化能力约为VE的550倍，在许多领域有着广阔的应用价值，如食品、医药等。因虾青素结构中存在较多共轭双键，故易受外界环境的影响而发生降解氧化。针对虾青素这一特性，主要探讨喷雾干燥过程中壁材及干燥温度等因素对虾青素微胶囊包埋效果的影响，并分析了虾青素微胶囊在贮存过程中对外界环境因素的耐受情况；同时对虾青素微胶囊现阶段在食品领域中的应用现状进行了总结，为日后虾青素产品的开发及广泛应用提供新思路。%Natural astaxanthin is a novel powerful antioxidant, whose antioxidant capacity is 550 times higher than Vitamin E. It has been widely applied in food, pharmaceutical industry. The astaxanthin can be easily de-graded by environmental conditions because of its unsaturated double bonds. This paper mainly explored the ef-fect of different conditions in spray drying process on astaxanthin microcapsules, such as wall material and dry-ing temperature etc. It also analyzed the stability of astaxanthin microcapsules during storage. At the same time , the development status of astaxanthin microcapsules in food field was summarized, in order to provide a new idea for the widely exploitation and application of astaxanthin product in the future.
