Abstract
The invention relates to a method and a composition for the enzymic determination of aspartame in aqueous solutions. The method is carried out such that the sample solution is incubated essentially in the presence of oxo-glutarate, glutamate-oxaloacetate transaminase (GOT), malate dehydrogenase (MDH), NADH and a protease, and the decrease in the NADH extinction is measured photometrically.
