Citric Acid Anhydrous - The Must-Have Acidifier for Beverages and Pastries
Citric Acid Anhydrous is a key organic acid and multifunctional additive renowned for its pleasant sourness, excellent chelating ability, and high biodegradability. It serves as a fundamental ingredient across food, beverage, pharmaceutical, and industrial sectors.
Primarily produced through the microbial fermentation of carbohydrate sources by Aspergillus niger, followed by extraction, purification, and crystallization.
Aliases
3-Carboxy-3-hydroxypentanedioic Acid
English Name
Citric Acid Anhydrous
Chemical Formula
C₆H₈O₇
Molecular Weight
192.12
CAS Number
77-92-9
Key Properties: Pleasant sour taste, strong chelating agent, highly water-soluble, naturally derived and biodegradable.
Advanced Application Scenarios
1. Acidulant and Flavor Enhancer in Food & Beverage
The primary acidulant in soft drinks, juices, and candies, providing a refreshing tartness and balancing sweetness
Acts as a preservative and pH regulator in jams, jellies, and canned foods, extending shelf life and maintaining color
2. Effervescent Agent and Stabilizer in Pharmaceuticals
A crucial component in effervescent tablets and powders (e.g., for vitamins or analgesics), reacting with carbonates to produce carbon dioxide for rapid dissolution
Used as an excipient in formulations to adjust pH, improve stability, and enhance the solubility of active ingredients
3. Green Chelant and Cleaning Booster in Household & Industrial Cleaning
A key ingredient in eco-friendly detergents and cleaners, effectively chelating and sequestering hard water ions (Ca²⁺, Mg²⁺) to improve cleaning efficiency and prevent scale
Used in metal cleaning and passivation treatments to remove oxides and rust without the environmental impact of strong mineral acids
4. Builder and Modifier in Chemistry & Materials
Acts as a plasticizer and cross-linking agent in the production of biodegradable polymers
Serves as a retarding agent in cement and plaster to control setting time
Technological Breakthroughs and Sustainable Development
Fermentation Efficiency
Continuous strain improvement through metabolic engineering has significantly increased fermentation yield and reduced production cycle times
Utilization of low-cost, non-food agricultural waste (e.g., molasses, cassava bagasse) as fermentation feedstocks enhances sustainability
Purification and Crystallization
Implementation of advanced membrane filtration and ion-exchange technologies ensures high purity and low levels of impurities like oxalate and sulfate
Controlled crystallization processes produce consistent particle size distributions optimal for various applications (e.g., powder flow, dissolution rate)
Green Manufacturing
Process water is extensively recycled within the production plant, minimizing freshwater intake and wastewater discharge
Energy-efficient evaporation and drying technologies are employed to reduce the overall carbon footprint
Quality and Compliance
Rigorous quality control protocols ensure compliance with major international standards such as USP, EP, FCC, and JP
Certifications like ISO 9001, FSSC 22000, and Halal/Kosher cater to global market requirements
