    Abstract:
    OBJECTIVE: To analyze the fatty acids in human milk, bovine milk and powdered formulas with the change of lactation period and suitable object. METHODS: A total of 50 human milk samples of healthy maternal, 35 Holstein milk samples and 30 formula samples were selected. The fatty acids in different samples were tested by gas chromatography. RESULTS: 28 fatty acids were detected in powdered formulas, 30 fatty acids were detected in bovine milk and 27 fatty acids were detected in human milk. The proportions of palmitic acid, oleic acid and linoleic acid were at a high proportion in all powdered formulas samples. The most common type of human milk fatty acids were oleic acid, linoleic acid and palmitic acid. The proportion of γ-linolenic acid and linoleic acid in bovine milk samples decreased, the proportion of arachidonic acid was significantly higher, and palmitic acid, gadoleic acid, cis-13-docosenoic acid and erucylacetic acid decreased with the change of lactation period. Linoleic acid, arachidonic acid, α-linoleic acid and docosahexenoic acid decreased significantly with change of suitable object. CONCLUSION: The production of powdered formulas must refer to fatty acids in human milk composition rationally, focus on adjusting the content of linoleic acid, linolenic acid, docosahexenoic acid and arachidonic acid in order to promote the best nutrition supply.
