Extraction and Refinement of the Oil from Cultured Crocodile

摘要: 文中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.

Abstract: 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.
