| Abstract: |
| Branched-chain fatty acids (BCFA) are trace but important bioactive components in milk for the growth and development of infants and children. The BCFA compositions and contents of breast milk and four different animal milk (milk, yak milk, goat milk, camel milk)were analyzed by GC-MS. The results showed that a total of 64 fatty acids were identified from five types of samples, including 15 BCFA，17 saturated fatty acid （SFA）, 18 monounsaturated fatty acid （MUFA） and 14 polyunstatured fatty acid （PUFA）. BCFA content presented a great difference among species. BCFA contents were significantly higher in the animal milk than in breast milk (p<0.001). The relative contents of BCFA in milk, yak milk, goat milk, camel milk and breast milk were 2.82%, 4.90%, 3.35%, 8.00% and 0.28%, respectively, in which most of them were iso-BCFA and anteiso-BCFA. The gestational age had a significant effect on the content of BCFA in breast milk (p<0.01),and breast milk of full-term mothers was rich in BCFA. |
