摘要/Abstract

摘要： 对5 种脂质来源婴儿配方奶粉（infant formula powder，IFP）与母乳（human milk，HM）在甘油酯组成上进行比较研究。结果表明：不同脂肪来源的IFP与HM在脂肪组成、组分比例上有显著差异，HM中甘油二酯（diglyceride，DG）相对含量高达（7.84±0.57）%，显著高于IFP的最高对应值（1.26±0.22）%（P＜0.05），其中DG(18∶2/18∶2)和DG(18∶1/18∶1)是HM中含量最高的DG种类，二者共占HM总DG的80%以上；在甘油三酯（triglyceride，TG）组成上，虽目前IFP已添加1,3-二油酸-2-棕榈酸甘油三酯成分，但TG(16∶0/18∶1/18∶1)相对含量（最高（6.70±0.19）%）仍显著低于HM对应值（（7.92±0.58）%）（P＜0.05），同时，IFP中TG(16∶1/17∶2/22∶6)相对含量最低为（3.68±0.67）%，显著高于HM（0.02±0.01）%（P＜0.05），这说明IFP中C22∶6的主要存在形式与HM不同。虽然目前IFP在主要脂肪酸组成上接近HM，但其在脂肪酸的存在形式上仍与HM存在明显不同。

Abstract: A comparative analysis of the glyceride composition in infant formula powders (IFP) with five different fat sources and human milk (HM) was studied. The results showed that there were significant differences in the fat composition between HM and IFP. The content of diglyceride (DG) in HM was (7.84 ± 0.57)%, which was significantly higher than the maximum level in IFP, (1.26 ± 0.22)% (P < 0.05). DG(18:2/18:2) and DG(18:1/18:1) were the most abundant types of DG in HM, together accounting for more than 80% of the total DG. In terms of triglyceride (TG) composition, even though 1,3-dioleoyl-2-palmitoyl triglyceride (OPO) has been added to it, the content of TG(16:0/18:1/18:1) in IFE, whose maximum level was (6.70 ± 0.19)%, was significantly lower than that in HM, (7.92 ± 0.58)% (P < 0.05). In addition, the content of TG(16:1/17:2/22:6) in IFP, whose minimum level was (3.68 ± 0.67)%, was significantly higher than that in HM (0.02 ± 0.01)% (P < 0.05), indicating that the major existing form of C22:6 in IFP was different from that in HM. Although IFP was close to human milk in the composition of major fatty acids, the existing form of fatty acids in IFP was obviously different from that in HM.
