Abstract
Determination of amino acids is highly demanded in food analysis, fermentation control and the chemical laboratory. Enzyme membrane electrodes have been successfully applied for the measurement of glutamate /1/, lysine /2/ and tyrosine /3/ in foodstuffs. The determination of amino acids using a chemically modified enzyme electrode has been described TAGS/ The aim of the present investigations is the comparison of the analytical performance of monoenzyme electrodes for L-glutamate, L-lysine and L-tyrosine using selective oxidases with that of a sensor based on group-specific L-amino acid oxidase (L-AAOD). Furthermore, lysine Oxidase, glutamate oxidase and tyrosinase have been coimmobilized in front of an Oxygen electrode to give a sensor which responds to the respective amino acids in mixtures.
