L-Malic acid, colorimetric method Catalogue number: AK00191, 5 x 10 tests Application
This rapid and simple colorimetric method is used for the determination of L-malic acid (L-malate) in a wide range of matrices. Although specially developed for quantification of L-malic acid in wine industry, this kit is also adequate to L-malic acid measurement in other foodstuffs such as fruit juice, beer, bread, fruit and vegetable products, as well as in cosmetics, pharmaceuticals and biological samples.
Simple, robust, and accurate, this assay can be performed using an inexpensive visible spectrophotometer.
