母乳对婴儿的生长发育非常重要，而低聚糖是母乳的主要功能性营养素之一。为了能够系统地比较来自不同物种的乳汁中的游离寡糖和糖缀合物含量，结合苯酚-硫酸和间苯二酚测定来测定含量。使用真实的样本，该方法显示，人乳中含有最高量的总中性（9.84 ± 0.31 g/L），唾液酸化（3.21 ± 0.11 g/L）游离低聚糖，其次为羊奶，中性（0.135 ± 0.015 g/L）和唾液酸化（0.192 ± 0.016 g/L）低聚糖，牛、牦牛乳中低聚糖含量较低。牦牛乳中总糖结合物含量最高（0.798 ± 0.011 g/L），其次为人乳、牛乳和羊奶。这些结果表明，山羊乳是婴儿配方奶粉和功能性乳制品中游离低聚糖的最佳来源，牦牛乳是糖复合物的最佳来源。
Human milk is important for infant growth, and oligosaccharides are one of its main functional nutrients. To enable a systematic comparison of free oligosaccharide and glycoconjugate content in milk from different species, the phenol-sulfuric acid and resorcinol assays were combined to determine the content. Using real samples, the method revealed that human milk contained the highest amount of total, neutral (9.84 ± 0.31 g/L), and sialylated (3.21 ± 0.11 g/L) free oligosaccharides, followed by goat milk, with neutral (0.135 ± 0.015 g/L) and sialylated (0.192 ± 0.016 g/L) free oligosaccharides and at a distance by bovine and yak milk. The highest total glycoconjugate content was detected in yak milk (0.798 ± 0.011 g/L), followed by human, bovine, and goat milk. These findings suggest that goat milk is the best source of free oligosaccharides in infant formula and functional dairy products and yak milk is the best source of glycoconjugates.
