The study of the composition of human milk has attracted worldwide interest, since it represents the pattern of nutrients most suitable for the younger infant. In the present study, the concentration of Ca, Mg, Fe, Cu, and Zn was measured in a total of 211 samples of human milk. The analytical technique of inductively coupled plasma atomic emission spectrometry (ICP-AES) was used for the analysis. From the results, it indicates that the mean concentration of Zn is highest in the colostrum with decreasing concentrations as the lactation progressed. The effects of age, parity, and lactation history on the results are also analyzed. It shows that the Zn concentration in the colostrum in the older mothers (>30 yr) was higher than that of the younger ones (20-30 yr).
人乳成分的研究引起了全球关注，因为它代表了最适合婴儿的营养模式。在本研究中，共测定了211份人乳样本中的钙、镁、铁、铜和锌浓度。采用电感耦合等离子体原子发射光谱法（ICP-AES）进行分析。结果表明，初乳中锌的平均浓度最高，随着哺乳期的推进浓度逐渐降低。还分析了年龄、胎次和哺乳史对结果的影响。结果显示，年龄较大的母亲（>30岁）初乳中的锌浓度高于年龄较小的母亲（20-30岁）。
