Description
What Is Citric Acid?
- Chemical identity: 2-hydroxy-1,2,3-propane-tricarboxylic acid (C₆H₈O₇)
- Source: Naturally found in citrus fruits; industrially produced via fermentation of sugars by Aspergillus niger.
- Forms: Available as anhydrous or monohydrate crystalline powder.
Key Benefits
- pH control: Acts as a primary acidulant in food and beverages.
- Chelation: Binds metal ions (e.g., calcium, magnesium, iron), improving stability and preventing discoloration or oxidation.
- Preservation: Inhibits microbial growth by lowering pH and disrupting cell membranes.
- Flavor enhancement: Adds tartness and balances sweetness in formulations.
- Biodegradability: Environmentally friendly and safe for use in green formulations.
