| 中文摘要: |
| 为寻找与中国人乳脂脂质组成高相似的天然人乳替代脂，分析比较了3种鱼油(金鲳鱼油、银鲳鱼油和巴沙鱼油)的总脂肪酸、sn-2位脂肪酸、甘油三酯组成和含量。结果表明：金鲳鱼油中棕榈酸、油酸和亚油酸含量分别为24.93%、25.61%和26.52%，其中sn-2位棕榈酸的含量为39.71%，占总棕榈酸比例为53.10%；在3种鱼油中，金鲳鱼油总脂肪酸组成最接近中国人乳脂；甘油三酯组成分析结果证实，金鲳鱼油中富含1-油酸-2-棕榈酸-3-亚油酸甘油三酯（OPL,24.36%），其含量显著高于其他两种鱼油，且其1,3-二油酸-2-棕榈酸甘油三酯（OPO）的含量（16.79%）接近报道的中国人乳脂的平均含量（15.84%）。因此，金鲳鱼油是理想的中国婴儿配方奶粉专用油脂基料油，在人乳替代脂中具有良好的发展前景。 |
| 英文摘要: |
| To find natural human milk fat substitute with high similarity to the lipid composition of Chinese human milk fat, the composition and content of total fatty acid, sn-2 fatty acid, and triglyceride of three types of fish oil (gold pomfret oil, silver pomfret oil, and barramundi oil) were analyzed and compared. The results showed that in gold pomfret oil, the contents of palmitic acid, oleic acid and linoleic acid were 24.93%, 25.61% and 26.52%, respectively. The content of sn-2 palmitic acid was 39.71%, accounting for 53.10% of the total palmitic acid. Among the three fish oils, gold pomfret oil exhibited the closest total fatty acid composition to Chinese human milk fat. The results of triglyceride composition analysis confirmed that golden pomfret fish oil was rich in 1-oleoyl-2-palmitoyl-3-linoleoylglycerol (OPL,24.36%), which was significantly higher than the other two fish oils, and its 1,3-dioleoy1-2-palmitoylglyecrol (OPO) content (16.79%) was close to the average content of reported Chinese human milk fat (15.84%). Therefore, golden pomfret fish oil is an ideal lipid base oil for Chinese infant formula, which has a good development prospect in human milk fat substitute. |
