Changes in Fatty Acids Among Colostrum, Transitional, and Mature Milk from Chinese Women
摘要
Abstract
[Objective] To compare the levels of fatty acids among colostrum,transitional,and mature milk in Chinese women.[Method] We collected 72 human milk samples at postpartum 1 ～5d,6 ～ 10d,and 30d from 24 mothers delivering full-term infants in Beijing.Fatty acids were determined by gas chromatography-mass spectrometer (GC-MS).[Result] Over the three stages,levels of C18∶0,C14∶1ω5,C18∶3ω6 and the ratio of ω-6/ω-3 increased significantly,while levels of C24∶0,C16∶1ω9,C20∶ 1ω9,C20∶2ω6,C20∶3ω6,C20∶4ω6 (AA),C22.2ω6,C22∶4ω6,C22∶5ω6,C22∶5ω3 and C22∶5ω3 (DHA) decreased (P ＜ 0.05).On the whole,total saturated fatty acids (SFA) remained stable,and polyunsaturated fatty acids (PUFA) especially ω-3 PUFA decreased significantly during the lactation (P ＜0.05).No significant changes were found in the level of total ω-6 PUFA.[Conclusion] Different fatty acids of human milk varied differently with lactating period.Therefore,the changes should be taken into account when feeding newborns banked human milk or human milk fortifiers and when designing infant formulas.关键词
