Buy Citric Acid Anhydrous and Monohydrate Wholesale from China Factory – 99.5% Purity, Free USA Sample in 7 Days
Struggling with high prices, inconsistent quality, and skyrocketing shipping costs for citric acid in your food, pharma, or feed operations? As a US purchasing manager, secure reliable citric acid anhydrous and monohydrate direct from our 20+ year fermentation factory – cut costs by 30% in 90 days, risk-free.
Citric acid anhydrous and monohydrate are cornerstone ingredients in food additives, feed additives, and pharmaceutical intermediates. Produced via fermentation of high-quality corn starch, these versatile acids serve as acidity regulators, preservatives, antioxidants, and flavor enhancers. At Shijiazhuang Standard IMP&EXP CO.,LTD., our two dedicated fermentation departments ensure 99.5-99.9% purity for both forms, meeting FDA standards for USA imports.
Citric acid monohydrate (CAS: 5949-29-1) contains one water molecule, appearing as colorless translucent crystals with a water content of about 8.8%. It's highly soluble in water (59g/100ml at 20°C), making it ideal for beverages, jams, and effervescent tablets where hydration stability matters. In contrast, citric acid anhydrous (CAS: 77-92-9) is a dry, white crystalline powder with zero water content, offering superior stability in powdered mixes, dry blends, and high-temperature processes. Both forms share the formula C6H8O7 but differ in density (monohydrate: 1.665 g/cm³; anhydrous: 1.665 g/cm³ adjusted for water) and melting points (monohydrate dehydrates at 135°C; anhydrous melts at 153°C).
In food manufacturing, citric acid anhydrous prevents enzymatic browning in fruits (e.g., 0.1-0.5% in apple slices), while monohydrate excels in dairy (cheese, yogurt) for pH control between 3.2-5.5. Pharma applications include buffering in syrups and effervescent formulations, with monohydrate preferred for its solubility. Feed additives use both to improve palatability and nutrient absorption in poultry and swine rations. Our production process—fermentation with Aspergillus niger, decolorization, crystallization, and drying—yields heavy metal content <1ppm, arsenic <0.2ppm, compliant with USP/EP/BP/FCC standards.
Why the distinction matters for your ROI: Anhydrous form reduces shipping weight by 10% (no water), slashing USA import costs. Monohydrate suits humid climates for easier dissolution. Global demand surges 5.2% annually (Statista 2026 forecast), driven by clean-label trends. Choose wisely to avoid 37% average overpricing from middlemen.
Fermentation details: We use non-GMO corn starch fermented at 30-35°C for 5-7 days, achieving 15-18% citric acid yield. Decolorization via activated carbon removes impurities, followed by ion-exchange purification. Crystallization at 40°C forms monohydrate; vacuum drying at 80°C produces anhydrous. Quality checks include HPLC for purity, titration for assay (min 99.5%), and microbial tests (total plate count <1000 CFU/g). Packaging: 25kg PE bags, 1000kg big bags, palletized for sea freight to USA ports like Los Angeles or New York.
Regulatory compliance for USA: FDA GRAS status, Kosher/Halal certified. No sulfites or heavy metals exceeding limits. Actual uses: Food (soda, candy: 0.3% dosage); Pharma (vitamin C tablets); Cosmetics (pH adjuster); Detergents (builder). Pricing: Anhydrous $1.20-1.50/kg FOB Tianjin; Monohydrate $1.10-1.40/kg (2026 spot). Payment: T/T 30% advance, L/C at sight, Alibaba Trade Assurance.
Compared to competitors, our China's supply chain advantage: Direct factory-to-USA delivery in 15-25 days via consolidated shipping, vs. 45+ days from Europe. OEM/ODM: Custom granulation (20-50 mesh), blending with ascorbates.
Your Top 5 Pain Points Sourcing Citric Acid Anhydrous and Monohydrate in 2026 USA Market
1. Skyrocketing Prices (Up 25% YoY)
Middlemen inflate costs to $2.50/kg, eroding your margins amid inflation.
