Citric acid powder is a fine, white crystalline substance naturally found in citrus fruits like lemons, limes, and oranges. It is highly soluble in water, has a tangy taste, and functions as an effective acidulant, preservative, and flavor enhancer. Commercially, it is often produced through the fermentation of plant-based sugars using microorganisms such as Aspergillus niger, which allows large-scale, cost-effective production without relying solely on fruit sources.
