Enzytec™ L-Malic Acid is an enzymatic test for the determination of L-Malic Acid in foodstuffs and other materials.
For in vitro use only.
General Information:
L-malic acid is one of the most important fruit acids, and the quantitative determination of L-malic acid is especially important in the manufacture of wine, beer, bread, fruit and vegetable products, as well as in cosmetics and pharmaceuticals. Microbial decomposition of L-malic acid leads to the formation of L-lactic acid, which can be a desirable reaction in the production of wine (malo-lactic fermentation, biological de-acidification), or an undesirable reaction in the case of beer (second fermentation). L-malic acid also finds many applications as a food preservative (E296) because it is a stronger acid than citric acid and as flavor enhancing compound.
