Citric Acid: Manufacturing Process Overview
Citric acid is one of the most commonly used organic acids utilized in food, pharmaceutical, and industrial applications. It is a naturally occurring substance that is primarily derived from citrus plants, but it is processed at a large scale by means of fermentation. Whichever method is used to produce citric acid, the manufacturing process provides for consistent quality, good yield, efficiencies in costs and environmental impact, and or for regulatory compliance purposes.
1. Raw Materials
Citric acid is synthesized from carbohydrate-containing raw materials. These represent the primary carbon source to carry out the fermentation process by the microorganisms. Typical raw materials include:
- molasses from sugarcane or sugar beet
- cornstarch or glucose syrup
- other sugar sources, depending on supply in the local market
These raw materials supply the sugars required for microbial metabolic processes.
2. Fermentation
The most widely used method for citric acid production is submerged fermentation with the mold Aspergillus niger.
- The microorganism is cultivated in a controlled environment with optimal temperature, aeration, and pH.
- During fermentation, A. niger converts sugars into citric acid as the primary metabolic product.
- Nutrient limitation (particularly nitrogen and phosphorus) is carefully managed to favor citric acid accumulation rather than biomass growth.
3. Separation and Recovery
After fermentation, the broth contains citric acid along with residual sugars, fungal biomass, and byproducts. Recovery involves:
- Filtration – Removing fungal biomass and solids.
- Precipitation – Adding lime (calcium hydroxide) to form calcium citrate.
- Acid Treatment – Treating calcium citrate with sulfuric acid to release citric acid and form calcium sulfate (gypsum) as a byproduct.
4. Purification
The crude citric acid solution undergoes several refining steps:
- Filtration – to remove gypsum and impurities
- Activated carbon treatment for decolorization
- Ion exchange for removing trace minerals and proteins
- Concentration through evaporation
5. Crystallization and Drying
The purified solution is cooled and crystallized to obtain citric acid crystals. These crystals are then
- Separated by centrifugation
- Washed to remove residual mother liquor
- Dried in hot air dryers to achieve the desired moisture content
The final product can be marketed as citric acid anhydrous or citric acid monohydrate, depending on drying conditions.
6. Quality Control
Throughout the process, strict quality checks are conducted to ensure compliance with food, pharmaceutical, and industrial standards. Key parameters include purity, color, solubility, and microbial safety.
7. Byproducts and Sustainability
- Calcium sulfate (gypsum) is generated as a byproduct and may be utilized in construction or agriculture.
Efforts are ongoing to optimize fermentation efficiency, reduce waste, and use renewable raw materials for greener production.
Applications of Citric Acid in Various Industries
Food & Beverages – Enhances flavor, acts as a preservative, and balances acidity in juices, soft drinks, candies, and packaged foods.
Pharmaceuticals – Used as a stabilizer, excipient, and effervescent base in tablets, syrups, and vitamin supplements.
Cosmetics & Personal Care – Helps maintain pH balance in creams, shampoos, face washes, and bath products.
Cleaning & Detergents – Effective in removing limescale, stains, and mineral deposits in household and industrial cleaners.
Industrial Applications – Plays a role in water treatment, textiles, and chemical formulations.
