Product Description
Food Grade Citric Acid Anhydrous for Industry and Cosmetics
Citric Acid Monohydrate is a crucial organic acid and multifunctional additive, renowned for its pleasant sour taste, excellent chelating ability, and high biodegradability. It serves as a fundamental ingredient in the food, pharmaceutical, and industrial sectors. The product is primarily produced through microbial fermentation of carbohydrate sources by Aspergillus niger, followed by extraction, purification, and crystallization to form the monohydrate.

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
- Serves as the primary acidulant in carbonated beverages, fruit juices, and confectionery, 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 product quality
2. "Effervescent Agent and Stabilizer" in Pharmaceuticals
- A key 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 with minimal environmental impact
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 and improve workability
Technological Breakthroughs and Sustainable Development
Fermentation Efficiency
- Continuous strain improvement through metabolic engineering has significantly increased fermentation yield and reduced production costs
- Utilization of low-cost, non-food agricultural residues (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
- Controlled crystallization processes produce uniform monohydrate crystals with optimal moisture content and consistent particle size distribution
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 diverse global market requirements
