title: Analysis of aspartic acid racemization. Evaluation of a chiral capillary gas chromatographic and a diastereomeric high-performance liquid chromatographic method.
abstract: A recently developed chiral gas chromatographic method and a diastereomeric high-performance liquid chromatographic method for the analysis of aspartic acid enantiomers in protein hydrolyzates have been evaluated. Although both techniques are fast and convenient, the latter is preferred because of its higher reproducibility and shorter analysis time. Furthermore, this method offers the possibility of on-line derivatization and analysis.
