摘　　要： 通过单因素实验和正交实验,对乌贼墨多糖的提取工艺进行了研究。主要考察了不同料液比、pH、提取温度以及提取时间对多糖得率及含量的影响,同时比较了活性炭吸附和高速离心法对乌贼墨黑色素的去除效果。实验结果表明:高速离心法去除黑色素方法优于活性炭吸附;乌贼墨多糖最佳提取工艺条件为:料液比为1∶2,pH为5,提取温度为40℃,提取时间为4h,此条件下乌贼墨多糖得率为1.228%,糖含量为78%,初步纯化后蛋白脱除率为90.52%,多糖的损失率为12.45%。 Extraction of the cuttlefish ink polysaccharide was studied through single- factor experiment and orthogonal test.The ratio of material to liquid,pH,temperature and extracting time were studied by extraction rates of polysaccharides.AIso activated carbon adsorption and high-speed centrifugation on the removal of the effect of Sepia melanin was compared.The results showed that activated carbon adsorption was better than high-speed centrifugation,the optimum conditions of extraction squid ink polysaccharide was.liquid ratio 1：2, pH5 ,temperature 40℃ and 4h for extracting, at this point the yield of polysaccharides was 1.228% ,the content of polysaccharides was 78%After purified, protein removal rate was 90.52% ,the loss rate of polysaccharides was 12.45%.
