摘　　要：对比了原料不同干燥方式对虾油酸价和虾青素含量的影响,以及溶剂体系对虾油得率、磷脂得率、虾青素得率的影响。在该基础上,探究原料粉碎程度、提取温度、提取时间和料液比对虾油得率的影响,并通过正交试验优化提取工艺。结果表明:冷冻干燥法提取的虾油酸价最低,虾青素含量最高;采用95%乙醇提取,虾油、磷脂以及虾青素得率最高;以冷冻干燥、粉碎后过60目筛的虾壳为原料,95%乙醇为提取溶剂,正交优化后的最佳提取工艺为:料液比19(g/mL),提取温度50℃,震荡提取时间30 min,该条件下虾油得率(12.64±0.02)%。The extraction of oil from Antarctickrill shell by organic solvent was studied in this paper.The effect of drying methods on krill oil qualities（Content of astaxanthin and acid value）were studied.In addition,the yield of oil,phospholipids,and astaxanthinwere compared while different extrantsolvents were used.Oil extracted from raw material processed by Freeze-drying hadthe highest astaxanthin content and the lowest acid value which made this method the best choice.When 95% ethanol was used,there were the highest yeild of krill oil,phospholipid and astaxanthin.With orthogonal experiment,the influence of material particle size,extraction temperature,extraction time,solid/liquid ratio on krill oil yield was studied and optimal technique parameters were as follows：particle size,over60mesh;temperautre,50℃;Time,30min;solid/liquid ratio,19.The highest oil yeild was（12.64± 0.02）%.
