摘要
为寻求我国大鲵资源利用新途径,并建立大鲵尾部油的最佳提取方法及工艺,采用酶解法从大鲵尾部脂肪组织中提取大鲵尾部油,并对所得的大鲵尾部油进行理化性质及脂肪酸组成分析。结果表明,酶解法提取大鲵尾部油的最佳工艺条件为:酶添加量0.3%,料液比1∶1.0,酶解时间1.0 h,酶解温度60℃,p H 6.5;在最佳条件下,提取率为98.53%。所提的大鲵尾部油达到我国水产行业SC/T 3502—2000粗鱼油的一级标准。酶解法所提大鲵尾部油中检测出17种脂肪酸,单不饱和脂肪酸(MUFA)含量为49.42%,多不饱和脂肪酸(PUFA)含量为29.35%。
The oil was extracted from the tail adipose tissue of Giant Salamander by enzymatic hydrolysis method so as to seek a new way for the utilization of Chinese Giant Salamander resource. Then the physicochemical properties and fatty acid composition of Giant Salamander tail oil were analyzed. The results showed that the optimal enzymatic extraction conditions of Giant Salamander tail oil were obtained as follows： dosage of enzyme 0. 3%,ratio of solid to liquid 1∶ 1. 0,enzymolysis time 1. 0 h,enzymolysis temperature 60 ℃,p H 6. 5. Under the optimal conditions,the extraction rate was 98. 53%. The Giant Salamander tail oil extracted reached the first grade standard of crude fish oil（SC / T 3502—2000）. 17 kinds of fatty acids were detected from the Giant Salamander tail oil,and the contents of MUFA and PUFA were49. 42% and 29. 35% respectively.
