Abstract A method for the determination of amino acids in feed hydrolysates is described. The method uses precolumn phenylisothiocyanate (PITC) derealization and liquid chromatography on reverse phase columns with UV detection at 254 nm. The precision of the method on replicate samples of a wheat hydrolysate ranges from 1.9 to 6.7% relative standard deviation for the amino acids examined. (Met and Cys were not determined.) Recoveries were near 100% for most amino acids. Comparisons of the values obtained by PITC method with accepted wines show good agreement in wheat and poultry feed samples.
