Citric acid (C₆H₈O₇), a weak organic acid naturally abundant in citrus fruits, is primarily produced via microbial fermentation using Aspergillus niger. It acts as a pH regulator, preservative, and flavor enhancer in food (70% of global use), while also serving pharmaceutical and industrial sectors like detergents, cosmetics, and water treatment. Central to the Krebs cycle, it converts nutrients into cellular energy. Stored in cool conditions to prevent combustion, its safety and versatility make it indispensable across industries.
