Determination of D- and L-isomers of tartaric and malic acids in wines, wine materials, and food additive
Naturally occurred is predominantly L-form of tartaric acid whereas its D-form and the relevant racemic mixture can be artificially synthesized. Generally, artificial acidification of wine with tartaric acid is allowed by OIV, but only pure L-form must be used for this purpose. Thus the analysis of tartaric acid isomers either in food additives or directly in wine can be an important parameter in clarifying any deviations in wine production. Analysis of isomers of malic acid is also within the necessary...
