Question: Describe the methods of preparation properties and structure of citric acid?
Citric acid is a weak organic acid that is widely used as a food additive and preservative. It can be prepared by fermentation of sugar solutions with the mold Aspergillus niger, or by extraction from citrus fruits. Citric acid has three carboxylic acid groups and one hydroxyl group in its molecular structure. It can form salts with metals and act as a chelating agent. Citric acid also plays a key role in the citric acid cycle, a metabolic pathway that produces energy in living cells.
