摘要
以人工养殖的鳄鱼脂肪为材料,根据传统淡碱水解工艺的提取原理,采用淡碱水解-乙醇萃取方法,对鳄鱼油的提取和精制工艺进行优化,并用气相色谱-质谱(GC-MS)分析检测精制鳄鱼油成分,结果显示:用优化后的工艺制备鳄鱼油,精制油得率达75%,色素和腥臭味得到有效脱除;鳄鱼油中含25种脂肪酸,其中不饱和脂肪酸含量占油脂总量的65.4%,不含铅、汞、砷等重金属.该方法简单、高效,制备成本低,适合大量提取制备.
In this study,we established a mild alkali-ethanol extraction method for the extraction and refinement of crocodile oil from cultured crocodile fat. The refined oil was obtained at a yield of 75% of the fat materials,without unfavorable and fishy smell; GC-MS analysis indicated that the refined oil contains 25 kinds of fatty acid and the unsaturated fatty acids accounted for 65.4% of oil,and is free of lead,mercury and arsenic. This work provides a simple and efficient method for large-scale preparation of high quality crocodile oil.
