Comparative milk fatty acid analysis of different dairy species

This study compared the fatty acid ( FA ) profile of milk from different dairy mammals: buffalo, camel, cow, goat and yak. Data from milk samples and reports in the literature were processed using principal component analysis. The results showed that camel milk contained the lowest levels of C4:0–C12:0 and highest levels of unsaturated fatty acids. Goat milk had the highest level of C8:0–C14:0 FA. Characteristic differences were observed for yak and buffalo milk, which differed from cow milk by their higher levels of saturated fatty acids and lower levels of polyunsaturated fatty acids. It is therefore suggested that each animal species’ milk has its own specific milk FA profile.
