| 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. |
