摘要
A fast and simple HPLC-method for the determination of synthetic amino acids in adulterated orange juice has been developed. The amino acid enantiomers were derivatized with a chiral reagent and the derivatives separated on a 3 μm particle size C18 column. An electrochemical detector operating in the oxidative mode was used for detection. The potential at which the derivatives are oxidized was determined by cyclic voltammetry. By using selective (electrochemical) detection it is possible to reduce the sample clean-up to simple centrifugation and filtration steps. © 1990 Friedr. Vieweg & Sohn Verlagsgesellschaft mbH.
