Abstract

A method for the simultaneous separation and determination of lysinoalanine (LAL), lysine, furosine and pyridosine with an automatic amino acid analyzer using a single Column 4 buffer- and 3 temperature-programme is described. The procedure needs 160 Minutes analysis time and allows a separation and quantitative determination of LAL, when present in amounts of more than 100 ppm (semiquantitative above 10 ppm). All amino acids found in food proteins and all other ninhydrinpositive compounds tested until now do not interfere with the determination.
