摘　　要：为探讨南美白对虾虾壳中天然虾青素的提取工艺,试验通过比较不同的前处理方式、溶剂类型及提取次数对提取率的影响,确定酸浸泡脱钙前处理、乙醇溶剂提取及二次浸提等工艺技术。进一步通过单因素试验和正交试验进行条件优化,获得乙醇提取虾青素的最佳工艺参数为料液比1∶10、pH3.0、温度60℃、时间3.5h。在此条件下,虾类加工副产物中的天然虾青素提取率为271.3μg·g-1。Conditions for extracting astaxanthin from Vannamei shrimps were studied. Decalcification with an acid soak, utilization of ethanol as the extraction solvent, and repeated extraction were found to be desirable for the operation. A single factor and orthogonal array experiment was conducted to further optimize that process which yielded the following processing conditions： solid：liquid ratio of 1：10, pH at 3.0, extraction duration of 3.5 h, and temperature at 60℃. The resultant rate of astaxanthin extracted from the shrimps was 271.3 μg·g-1. This study provided a basis for future development of the shrimp byproduct utilization technology.
