Application of Gas Chromatography to Analyses of Amino Acids.Peer-reviewed article

H. ŠEDOVÁ, M. KAHLER

The article deals in detail with the sequence of operations required for cleaning and derivatisation of amino acids and their estimation by applying gas chromatography methods. The Mac Kenzie-Tenashuka method has been modified and permits now to determine the amount of amino acids in wort, beer and wine. The applicability and reliability of the method have been verified through a series of analyses covering mixtures of pure amino acids, various sorts of wort, beer and wine. All analyses give reproducible results with deviations not exceeding 3 %. The method can be used to study changing concentrations of amino acids in the course of brewing processes or to evaluate the quality of malt.
