Summary Citric acid is one of the most important acids. It is the principal food acid, used in preparation of soft drinks and syrups. The first commercial citric acid was produced from citrus fruits, but it was discovered that citric acid could be produced on a commercial scale by some microorganisms, especially Aspergillus spp.

In the recent gasometric micro method for the determination of lactic acid in blood devised by Avery and Hastings which measures the carbon dioxide evolved upon oxidation with permanganate, these investigators obtained more carbon dioxide than could be accounted for by the lactic acid known to be present.

Chapter 4 offers an extensive description of the citric acid chemistry. It includes presentation of total syntheses of citric acid, preparations of labeled citric acid, typical reactions – neutralization, degradation, oxidation, esterification, formation of anhydrides, amides, citrate-based siderophores and other compounds.
