摘　　要：鱼油所含的磷脂是动物脑、神经组织、骨髓、心、肝和脾中不可缺少的组成部分,既有助于脂的消化吸收、转运和形成,又是生物膜的重要结构物质。目前金枪鱼下脚料的利用主要是提取活性多肽、胶原蛋白、生产鱼骨粉等。金枪鱼加工中产生大量的下脚料,如果用于提取鱼油,可以创造可观的经济效益。重点研究了酶解工艺条件对鱼油提取率的影响,结果表明,胰蛋白酶提取鱼油的酶解工艺参数为:酶解温度45℃,酶添加量1.5%,料液质量比为1:1,酶解时间4h,酶解pH值8。在此条件下,粗鱼油的提取率为4.32%。Fish oil contains phospholipids of animal brain,nerve tissue,bone marrow,heart,liver and spleen in an integral part,helping fat digestion and absorption,transport and the formation of biofilms is an important structural material.The current use of tuna scraps mainly extracted peptides,collagen,production of fish bone meal,etc.Tuna processing produce large amounts of waste,if used for extraction of fish oil,can create considerable economic benefits.This paper focuses on the hydrolysis process conditions on fish oil extraction rate.The results show that：trypsin digestion of fish oil extracted parameters for the hydrolysis temperature of 50 ℃,enzyme dosage 1.5%,substrate concentration ratio of 1：1,hydrolysis time 4 h,hydrolysis pH 8.Under these conditions,the extraction of crude fish oil was 5.32%.
