以新鲜海虾为材料，采用单因素实验研究了提取溶剂、料液比、提取温度、提取时间、提取次数对虾青素提取效果的影响，用紫外可见分光光度法测定了不同部位虾青素的含量，比较了煮熟虾壳与新鲜虾壳中虾青素的含量变化。结果表明，乙酸乙酯是提取虾青素的最适溶剂，最佳提取条件是：料液比1∶2（g∶mL）、提取温度60℃、提取时间3 h、提取2次。虾壳中虾青素含量最高，煮熟后虾壳中虾青素含量明显降低。

The astaxanthin was extracted from fresh shrimp.The effects of extraction solvent,solid-liquid ratio,extraction time,extraction temperature and extraction times on astaxanthin extraction efficiency were in-vestigated by single factor experiment.And the astaxanthin contents of different parts of shrimp were measured by UV-Vis spectrophotometry,the astaxanthin contents in fresh and cooked shrimp shell were compared.The results showed that,ethyl acetate was the most suitable solvent,the optimal extraction conditions were as fol-lows:extracting for 3 h each time at 60 ℃ with solid-liquid ratio of 1∶2(g∶mL),extracting twice.The highest astaxanthin content was in shrimp shell.The astaxanthin content decreased obviously in cooked shrimp shell.
