This UV Test is used for the determination of L-malic acid in foodstuffs such as beer, bread, fruit and vegetable products, fruit juice, beverages containing fruit juice, wine, as well as in cosmetics, pharmaceuticals (e.g. solutions for infusion) and biological samples.

L-Malic acid as a component of the citric acid cycle is an important substance in animals, plants and micro-organisms; it is one of the most important fruit acids and it is the acid with the highest concentration in wine. Stereo-specific L-malic acid can be produced biotechnologically/ enzymatically with fumarase by attaching water to fumaric acid (when synthesized chemically, the racemic D-/L-malic acid is produced).
L-Malic acid may be used in food production because it is a stronger acid than citric acid. Microbial decomposition of L-malic acid leads to the formation of L-lactate; this can e.g. be a desirable reaction in the production of wine (malo-lactic fermentation, biological de-acidification).
