Quantitative Analysis of Nervonic and Erucic Acids in Human Milk: Comparison with Infant Formula with Different Fat Sources and Nutritional Stages

抄録

This study aims to quantitatively analyze nervonic (C24:1 n-9) and erucic (C22:1 n-9) acids in human milk (HM) collected from Korean mothers, along with the infant formulas (IFs) with different fat sources and nutritional stages. The content of nervonic and erucic acids in HM from Korean mothers were 2.13 and 2.81 mg/100 g, accounting for 0.06 and 0.08% of the total fatty acids (FAs), respectively. These acids in IFs based on fat from plant-oil formula were higher than those in IFs based on cow milk formula. The composition of erucic acid in IFs based on cow milk formula and plant-oil formula increased with the nutritional stages, while nervonic acid only increased in IFs based on the plant-oil formula.
