Evaluation of enantiomeric purity of selected amino acids in honey.
Highly sensitive and accurate HPLC methods were used for the determination of total amounts of proline, leucine and phenylalanine and their enantiomeric ratios in a variety of different honey samples. Significant amounts of D-leucine and D-phenylalanine and relatively low concentrations of D-proline have been found in honeys of different botanical and geographical origins. It is suggested that the enantiomeric ratios of amino acids could be used to test for storage effects, age, and the quality of the processing of the honey.
