| 中文摘要: |
| 对巴沙鲶鱼油等市场上常见的10种淡水鱼油脂肪酸、sn-2脂肪酸组成进行了测定与分析。结果表明：大部分淡水鱼油中棕榈酸含量在15%~25%、油酸含量在25%~45%，和人乳脂肪较为接近；巴沙鲶鱼油、黑鱼油、鲈鱼油、鲤鱼油、白鲢鱼油sn-2棕榈酸含量分别为44.27%、40.91%、3131%、30.02%和31.02%，且sn-2棕榈酸分布均高于50%；巴沙鲶鱼油、黑鱼油的sn-1,3油酸含量在50%左右，并通过 UPLC-MS/MS验证了OPO的存在，推测适合作为人乳替代脂的基料油；鲤鱼油中中碳链脂肪酸C10∶?0和C12∶?0总含量超过10%，易于婴幼儿吸收；鲈鱼油中DHA含量为12.73%，对于婴幼儿智力发育有着关键作用，鲤鱼油和鲈鱼油适合作为人乳替代脂的配料油。 |
| 英文摘要: |
| Ten kinds of freshwater fish oils were collected and their fatty acid compositions and sn-2 fatty acid compositions were analyzed. The results showed that the contents of palmitic acid and oleic acid were in the ranges of 15%-25% and 25%-45% respectively in most freshwater fish oils, which were similar to human milk fat. The contents of sn-2 palmitic acid in basa catfish oil, black flah oil, bass oil, carp oil and silver carp oil were 44.27%, 40.91%, 31.31%, 30.02% and 31.02% respectively, and the distributions of sn-2 palmitic acid were all above 50%. The contents of sn-1,3 oleic acid of basa catfish oil and black flah oil were about 50%, and the existence of OPO was validated by UPLC-MS/MS. It was conjectured that basa catfish oil and black flah oil were suitable to be the base oil in human milk fat substitutes. The total content of medium chain fatty acid including C10∶?0 and C12∶?0 was above 10% in carp oil, which was easy for infants to absorb. The DHA content in bass oil was 12.73%, which played a key role in infants intelligence development. Carp oil and bass oil were suitable to be stock oil in human milk fat substitutes. |
