Anhydrous Citric Acid is the dehydrated form of citric acid, a natural weak organic acid derived from citrus fruits and commercially produced through microbial fermentation. This white crystalline powder exhibits higher acidity concentration compared to its monohydrate counterpart due to the absence of water molecules. With excellent water solubility and chelating properties, it serves as a versatile acidulant, pH regulator, and preservative across multiple industries. Its anhydrous nature makes it particularly valuable in moisture-sensitive applications and dry formulations.
