The invention discloses a method for producing a fish oil microcapsule from konjac glucomannan aerogel. The konjac glucomannan aerogel is prepared from konjac glucomannan, and fish oil is adsorbed tothe konjac glucomannan aerogel by using supercritical CO2. According to the invention, the konjac glucomannan and the fish oil are used as raw materials, sol-gel are combined with supercritical CO2 adsorption and embedding, a prepared spherical microcapsule is solidified to form a cross-linked network structure, and the embedding rate reaches 90.00% or above, so that the collapse is not likely tohappen at the high temperature, a core material can be well protected, and the excellent slow-release performance is achieved in a high-temperature and high-humidity environment; and therefore, the method has great application potential in the aspect of stability protection of functional factors. 本发明公开了一种利用魔芋葡甘聚糖气凝胶生产鱼油微胶囊的方法，将魔芋葡甘聚糖制成魔芋葡甘聚糖气凝胶，利用超临界CO2将鱼油吸附至魔芋葡甘聚糖气凝胶。本发明以魔芋葡甘聚糖和鱼油为原料，利用溶胶-凝胶结合超临界CO2吸附包埋，制备的球形微胶囊经固化后形成交联网状
