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.
