These Malic Acid test strips are ideal for the determination of decrease in malic acid concentration during the wine-making process.
Color Reaction: Malic acid (malate) is oxidized to oxaloacetate by NAD+ under the catalytic effect of malate dehydrogenase. In the presence of disphrose, the NDAH formed in the process reduces a tetrazolium salt to a red formazan, the concentration which is determined reflectometrically. Reflectoquant® Malic Acid Test Strips are used with the Reflectoquant® RQflex® 10 Meter Reflectometer Analysis System. Measuring Range: 5 to 60ppm. 50 Malic Acid Test Strips/Pack.
