| 摘 要： | 利用凯氏定氮仪和氨基酸自动分析仪对全脂奶粉中的蛋白质和氨基酸进行分析,测得全脂奶粉中氨基酸总量约占蛋白质含量的95%,各种氨基酸含量占氨基酸总量的比值的极差均小于0.010,氨基酸组成相对稳定,特征氨基酸检测快速、准确,各种分析数据可为建立系统的蛋白质监测技术体系提供理论依据。

| Abstract: | Using the Kjeldahl apparatus and automatic amino acid analyzer to analyze protein and amino acid in the whole milk powder. Total contents of amino acid account for about 95% of protein in the whole milk powder. The range of ratio of each amino acid contents to total contents of amino acid is less than 0.010. The compositions of amino acid are relatively stable and the detection of characteristic amino acid is fast and accurate. These entire analytical data can provide theoretical basis to the establishment of a scientific protein monitoring technology system. |
