Functions and Usages
Core Functions of Anhydrous Citric Acid
- Acidulant — sharp, clean sour taste; balances sweetness.
- pH regulator — controls acidity, texture and gelling.
- Preservative — lowers pH to inhibit bacteria and mold, extending shelf life.
- Chelating agent — binds trace metals to protect color and flavor.
- Antioxidant synergist — boosts effectiveness of vitamin C and other antioxidants.
- Flavor enhancer — sharpens fruit flavor, softens aftertaste of sweeteners.
- Moisture-control agent — adds no water, ideal for dry/effervescent formulas.
Applications by Industry
- Beverages — sodas, juices, sports drinks: acidity, flavor and color stability.
- Dry mixes & effervescent products — powdered drinks, tablets: no added moisture.
- Confectionery & baked goods — sweet-sour balance, gelling control.
- Jams, sauces & canned foods — preservation and freshness.
- Pharmaceuticals — excipient and CO2-generating agent in effervescent tablets.
- Cosmetics — pH adjuster and mild AHA exfoliant in skincare.
- Household/industrial — natural descalers and cleaning products.
Citric Acid Monohydrate vs. Anhydrous
| Form | CAS No. | Key Trait | Best For |

FAQ
Q1. What is Citric Acid Anhydrous?
Citric Acid Anhydrous is a water-free form of citric acid with the chemical formula C₆H₈O₇ and CAS No. 77-92-9. It is commonly supplied as a white crystalline powder or granules and is widely used as a food acidulant, acidity regulator, pH adjuster and chelating agent. It is also known as Anhydrous Citric Acid and is commonly identified as E330 in food applications.
Q2. What is the difference between Citric Acid Anhydrous and Citric Acid Monohydrate?
The main difference is their water content. Citric Acid Anhydrous contains no crystallization water, while Citric Acid Monohydrate contains one molecule of crystallization water. As a result, they have slightly different molecular weights and may require different dosage calculations in formulations. The appropriate type depends on the customer’s formulation, processing conditions and application requirements.
Q3. What is Citric Acid Anhydrous used for?
Citric Acid Anhydrous is widely used in food and beverage, confectionery, dairy products, sauces, processed foods, nutritional products and pharmaceutical formulations. It can provide acidity, adjust pH, enhance flavor and support product stability. Its good water solubility also makes it suitable for powdered beverages and other dry-mix formulations.
