The L-Malic Acid test kit is suitable for the measurement and analysis of L-malic acid in grapes, grape juice and wine using the MegaQuant? colorimeter (measurement at 505 nm). Suitable for white and red wines at all stages of the winemaking process.

Simple colourimetric method for the determination of L-Malic 
Acid in foodstuffs, beverages and other materials

Principle:
(L-malate dehydrogenase)
(1) L-Malic acid + NAD+ ? oxaloacetate + NADH + H+

(glutamate-oxaloacetate transaminase)
(2) Oxaloacetate + L-glutamate → L-aspartate + 2-oxoglutarate

(diaphorase)
(3) INT + NADH + H+ → NAD+ + INT-formazan

Kit size: 60 assays
Method: Spectrophotometric at 505 nm
Reaction time: ~ 6 min
Detection limit: 0.25 mg/L
Application examples:
Wine, beer, fruit juices, soft drinks, candies, fruit and vegetables,
bread, cosmetics, pharmaceuticals and other materials (e.g. biological
cultures, samples, etc.)
Method recognition: Novel method
