A reversed-flow injection method is proposed. Two enzymes, citrate lyase and malate dehydrogenase (MDH), are used, the latter being immobilized. This method, based on the decrease in the absorbance of reduced nicotinamide adenine dinucleotide, has a linear range between 1 and 20 mg dm-3. Additionally, a flow injection method for the determination of oxalacetic acid in fruit juices using immobilized MDH is also proposed.
