摘　　要：文章通过检测市售婴儿配方奶粉的糠氨酸质量分数和乳果糖质量浓度,分析影响糠氨酸质量分数和乳果糖质量浓度的因素。结果表明,糠氨酸质量分数为124.4~1210.3 mg/100 g蛋白质,乳果糖质量浓度为17.9~769.1 mg/L,原产地和主要原料种类对糠氨酸质量分数和乳果糖质量浓度无统计学差异(P>0.05),生产加工条件和贮存条件会产生影响。糠氨酸也可以作为乳制品中反映赖氨酸破坏程度的指标,市售婴儿配方奶粉的封闭赖氨酸占总赖氨酸为2.7%~20.5%,可利用赖氨酸平均质量分数为7.5 g/100 g蛋白质,略高于母乳平均水平(6.6 g/100 g蛋白质)。通过监测标志物的方法来控制婴幼儿配方奶粉的质量,为新鲜婴幼儿配方奶粉相关标准体系制定提供参考。Detect the mass fraction of furfuran and the concentration of lactulose in commercial infant formula milk powder,and analyze the factors affecting the mass fraction of furfuran and the concentration of lactulose.The results showed that the mass fraction of furfuran was 124.4-1210.3 mg/100 g protein,and the mass concentration of lactulose was 17.9-769.1 mg/L.There was no statistically significant difference(P>0.05)in the origin and main raw material types on the furfuran and lactulose,and production conditions and storage conditions would have an impact.Furfuran can also be used as an indicator of the degree of lysine damage in dairy products.The proportion of blocked lysine in commercial infant formula milk powder was2.7%-20.5%of the total lysine,and the average mass fraction of available lysine was 7.5 g/100 g protein,slightly higher than the average level of breast milk(6.6 g/100 g protein).This study aims to control the quality of infant formula by monitoring biomarkers,which can provide reference for the development of relevant standard systems for fresh infant formula.
