Thirty-four samples of human milk (HM) collected from mothers in Korea were classified into three groups according to their fat content. The lutein + zeaxanthin, β-cryptoxanthin, β-carotene, lycopene, α-carotene, and fatty acids (FAs) present in the HM were quantitatively analyzed. Lutein + zeaxanthin and β-cryptoxanthin were the most abundant carotenoid components in this study, followed by β-carotene. When the classified groups were compared in terms of the content of each carotenoid, there was no statistical difference ( > 0.05), indicating that there is no correlation between the content of fat and carotenoid in HM. The mean content of saturated FAs (SFAs), monounsaturated FAs, and polyunsaturated FAs in the analyzed HM were 1.46, 1.36, and 0.83 g/100 g, respectively. In addition, the mean content of arachidonic acid (AA) and docosahexaenoic acid (DHA) were 0.02 and 0.029 g/100 g, respectively. Alternatively, all FAs except for certain SFAs (i.e., C8:0, C10:0, C12:0, and C14:0) did not show statistical difference in composition among the three groups ( > 0.05), indicating that the differences in the fat content of HM have limited influence on the FA composition of HM.
从韩国母亲采集的 34 个人乳样本根据其脂肪含量分为三组。定量分析了乳中的叶黄素+玉米黄质、β-隐黄质、β-胡萝卜素、番茄红素、α-胡萝卜素和脂肪酸 (FA)。叶黄素+玉米黄质和β-隐黄质是本研究中最丰富的类胡萝卜素成分，其次是β-胡萝卜素。当按每种类胡萝卜素的含量对分类组进行比较时，没有统计学差异（>0.05），这表明乳中脂肪和类胡萝卜素的含量之间没有相关性。分析乳中饱和脂肪酸 (SFA)、单不饱和脂肪酸和多不饱和脂肪酸的平均含量分别为 1.46、1.36 和 0.83 g/100 g。此外，花生四烯酸 (AA) 和二十二碳六烯酸 (DHA) 的平均含量分别为 0.02 和 0.029 g/100 g。另外，除某些 SFA（即 C8:0、C10:0、C12:0 和 C14:0）外，所有 FA 在三组之间的组成上没有统计学差异（>0.05），这表明乳中脂肪含量的差异对乳中 FA 组成的影响有限。
