Winemaking: Tartaric acid is a primary organic acid in grapes and a fundamental constituent of wine. It contributes to the acidity, flavor, and overall quality of the wine. It helps in enhancing color stability, preventing oxidation, and inhibiting spoilage in wines .
Food Industry: It is used as an acidulant in carbonated drinks, effervescent tablets, gelatin desserts, and fruit jellies. It is also used in the production of baking powders, hard candies, and taffies .
Industrial Applications: Tartaric acid has numerous industrial uses, including cleaning and polishing metals, calico printing, wool dyeing, and certain photographic processes. It is also used in the electrolytic tinning of iron and steel and in coating other metals with gold and silver .
Chiral Chemistry: Due to its two stereocenters, tartaric acid exists as a pair of enantiomers and an achiral meso compound. It is widely used as a resolving agent and chiral ligand in asymmetric synthesis, particularly in the preparation of enantiomerically pure compounds .
Biological Production: There have been attempts to explore biological ways of producing tartaric acid, such as through the use of bacteria that show high enzymatic activity for the formation of L(+)-tartaric acid .
Crystallography and Stereoisomerism: The study of tartaric acid by Louis Pasteur laid the foundation for modern ideas of stereoisomerism. Pasteur was able to separate the acid into two enantiomers, which was a significant contribution to the understanding of molecular asymmetry .
Regulation of Acidity: In winemaking, tartaric acid is sometimes added to regulate the pH and acidity levels, especially in the face of decreasing acidity due to global warming, which can affect the microbial stability and aging potential of the wine .
Biosynthesis Pathway: Tartaric acid in grapes is synthesized from ascorbic acid through a series of enzymatic reactions, with L-idonate dehydrogenase being a key enzyme in this pathway .
