What is citric acid?

In 1917, American food chemist James Currie found that Aspergillus Niger's mold could produce citric acid as a by-product of sucrose or glucose metabolism, which proved to be more efficient and cheaper than extracting oranges. Although citric acid is found in high concentrations on many oranges such as lemon, it is not economical to extract the acid from the fruit for industrial use.

Plus, the demand for citric acid far outweighs the supply of citrus fruit available. Thus, once it was possible to produce a seemingly endless supply of citric acid, companies began manufacturing it on an industrial scale.
