Citric Acid Anhydrous (CAS 77-92-9) ，also known as anhydrous citric acid E330, is a high-purity, water-free organic acid widely used as an acidity regulator, preservative, and chelating agent in food, pharmaceutical, cosmetic, and industrial sectors. As a top Citric Acid Anhydrous supplier China, we provide ISO 9001, SGS-tested, Kosher & Halal certified products (≥99.5% purity) that meet USP, EP, FCC, and GB 1886.235-2016 standards, ideal for global export and moisture-sensitive formulations.
What is Citric Acid Anhydrous (CAS 77-92-9)?
Chemically named 2-hydroxypropane-1,2,3-tricarboxylic acid (molecular formula C₆H₈O₇, molecular weight 192.12), Citric Acid Anhydrous is produced via deep fermentation of corn starch or molasses using Aspergillus niger, followed by purification, crystallization, and vacuum drying at over 130°C to remove all crystal water. It appears as a white, odorless, crystalline powder or granules with a clean, refreshing sour taste—making it a preferred choice for manufacturers worldwide.

Top Applications of Citric Acid Anhydrous (E330)
With 62% of global demand coming from the food & beverage sector, Citric Acid Anhydrous is a versatile ingredient, supported by SGS test reports and ISO 9001 certification to ensure compliance across industries.
1. Food & Beverage Industry (E330 Food Additive)
As a GRAS (FDA-approved) food acidulant, Citric Acid Anhydrous E330 is widely used in soft drinks (0.05–0.3%), juices, candies, jams, canned goods, and dairy products. It balances sweetness, preserves color and flavor, inhibits microbial growth, and acts as an antioxidant—perfect for clean-label products seeking to replace synthetic preservatives. Our Food Grade Citric Acid Anhydrous meets FCC and GB 1886.235-2016 standards, ideal for export to EU, North America, and Southeast Asia.
2. Pharmaceutical & Cosmetic Industry
Pharmaceutical Grade Citric Acid Anhydrous (USP/EP/BP compliant) serves as a pH adjuster, flavorant, and effervescent agent in oral medications, topical creams, and ophthalmic formulations. In cosmetics, it acts as a pH balancer in lotions, facial masks, and oral care products, ensuring product stability and skin compatibility. Our Kosher Halal Citric Acid Anhydrous is suitable for global cosmetic and pharmaceutical export.
3. Industrial & Cleaning Sector (Fastest-Growing Demand)
Industrial Grade Citric Acid Anhydrous is a biodegradable chelating agent and phosphate replacement in eco-friendly detergents (EU/North America compliance). It is also used as a scale inhibitor in water treatment, a retarder in concrete, and a chelating agent in metal electroplating. With a 6.03% CAGR (2026–2031), this sector is driving global demand for high-purity Citric Acid Anhydrous.
Citric Acid Anhydrous vs. Monohydrate: Key Differences

FAQ
Q1: What is the difference between Food Grade and Industrial Grade Citric Acid Anhydrous?
Food Grade Citric Acid Anhydrous meets FCC, E330, and GB 1886.235-2016 standards, with strict limits on heavy metals (≤0.5 mg/kg) and microorganisms, suitable for food, pharma, and cosmetics. Industrial Grade focuses on impurity control (iron, sulfate) and is used for detergents, water treatment, and concrete—non-edible.
Q2: What certifications do I need for Citric Acid Anhydrous export?
For EU export: E330, SGS test report, ISO 9001, Kosher/Halal, and Pb ≤0.5 mg/kg. For North America: USP/FCC compliance and FDA GRAS certification. For Asia: ISO 9001 and cost-performance balance. We provide all required documents for global export.
Q3: Is Citric Acid Anhydrous suitable for organic/clean-label products?
Yes. It is naturally derived via fermentation (corn starch/molasses), biodegradable, and approved for organic food and cosmetics. It is widely used to replace synthetic acidulants and preservatives, aligning with global clean-label trends.
Q4: How should I store and transport Citric Acid Anhydrous?
Store in a cool, dry, ventilated area, sealed tightly to avoid moisture absorption. It is non-hazardous for sea and land transport; 25kg bags are ideal for small orders, while 500kg/1000kg jumbo bags are suitable for bulk Citric Acid Anhydrous export.
