【摘要】：目的分析不同泌乳期與嬰幼兒階段配方奶粉、牛乳與人乳中的脂肪酸組成情況。方法選擇50例健康產(chǎn)婦提供的人乳、35份荷斯坦牛牛乳與30份配方奶粉開(kāi)展臨床檢驗(yàn),以氣相色譜法檢測(cè)不同樣本的脂肪酸組成情況。結(jié)果配方奶粉中檢測(cè)出28種脂肪酸,牛乳中檢測(cè)出30種脂肪酸,人乳中檢測(cè)出27種脂肪酸。在所有配方奶粉中棕櫚酸、油酸與亞油酸的占比較高。人乳中各階段均以油酸、亞油酸與棕櫚酸為最常見(jiàn)脂肪酸類型。伴隨泌乳期階段變化,牛乳中γ-亞麻酸與亞油酸的占比明顯下降(P0.05),但花生四烯酸占比顯著升高(P0.05);人乳中棕櫚酸、順-11-二十烯酸、芥酸與神經(jīng)酸均明顯下降(P0.05)。伴隨嬰幼兒年齡增加其配方奶粉亞油酸、花生四烯酸、α-亞油酸與順式-4,7,10,13,16,19-二十二碳六烯酸的占比明顯下降。結(jié)論在生產(chǎn)配方奶粉時(shí)需參照人乳中脂肪酸組成進(jìn)行合理配置,著重調(diào)整亞油酸、亞麻酸、二十二碳六烯酸與花生四烯酸等重要脂肪酸含量,以促使嬰幼兒獲得最佳營(yíng)養(yǎng)供給。
[Abstract]:Objective to analyze the fatty acid composition in milk powder, milk and human milk at different lactation and infant stages. Methods Human milk, 35 Holstein milk and 30 formula milk supplied by 50 healthy parturients were selected for clinical examination. The fatty acid composition of different samples was detected by gas chromatography. Results 28 kinds of fatty acids were detected in formula milk powder, 30 kinds of fatty acids in milk and 27 kinds of fatty acids in human milk. Palmitic acid, oleic acid and linoleic acid account for higher percentage of palmitic acid, oleic acid and linoleic acid in all formula. Oil acid, linoleic acid and palmitic acid are the most common fatty acids in human milk. With the change of lactation stage, the proportion of gamma-linolenic acid and linoleic acid in milk decreased significantly (P 0.05), but the proportion of arachidonic acid increased significantly (P 0.05). Palmitic acid, cis-11-eicosenic acid, erucic acid and neuroacid in human milk decreased significantly (P 0.05). With the increase of infant age, the proportion of linoleic acid, arachidonic acid, 偽-linoleic acid and cis-4, 10, 13, 16, 19-22 carbohexaenic acid decreased significantly. Conclusion in the production of formula milk powder, the fatty acid composition in human milk should be reasonably allocated, and the contents of important fatty acids such as linoleic acid, linolenic acid, 22 carbohexaenic acid and arachidonic acid should be adjusted in order to obtain the best nutritional supply for infants and young children.
