Get Free Quote in 24hAs a cornerstone in food additives, feed additives, and pharmaceutical intermediates, citric acid anhydrous pH plays a pivotal role in achieving precise acidity control across industries. At Shijiazhuang Standard IMP&EXP CO.,LTD., we've mastered production using high-quality corn starch through advanced fermentation, decolorization, and crystallization processes, ensuring our citric acid anhydrous delivers a consistent pH range of 2.2-2.5 in 5% aqueous solutions. This exact pH specification meets USP, BP, and FCC standards, making it ideal for USA importers seeking reliable supply chains.
Citric acid anhydrous, chemically known as 2-hydroxypropane-1,2,3-tricarboxylic acid (C6H8O7), is a tricarboxylic acid naturally derived from citrus fruits but industrially produced via fermentation for purity and scale. Unlike its monohydrate counterpart, the anhydrous form contains no water of crystallization, offering higher concentration (typically 99.5-101.0% purity) and better solubility in dry blends. The citric acid anhydrous pH is a critical parameter: in a 5% w/v solution at 20°C, it measures between 2.2 and 2.5, reflecting its strong acidity (pKa1=3.13, pKa2=4.76, pKa3=6.40). This low pH enables effective pH adjustment, preservation, and chelation in formulations.
Why does pH matter? In food manufacturing, a precise citric acid anhydrous pH prevents microbial growth while maintaining flavor balance – think beverages where pH below 3.5 extends shelf life by 40%. In pharmaceuticals, it buffers injectables without altering bioavailability. For feed additives, it enhances nutrient absorption in animal digestion, improving feed efficiency by up to 15%. Our 20+ years of expertise ensure every batch tests to pH 2.2-2.5, verified by third-party labs like SGS.
Production insights: We operate two dedicated fermentation departments in Shijiazhuang, Hebei, China, sourcing non-GMO corn starch. The process involves Aspergillus niger fermentation, yielding 95%+ crude citric acid, followed by activated carbon decolorization (reducing color to 50 max Pt-Co), ion-exchange purification, and vacuum evaporation/crystallization. Final drying at 80-100°C produces snow-white crystals (APHA 50 max) with iron content <5ppm. pH testing uses calibrated glass electrodes per USP <791>, ensuring consistency. This results in a product with loss on drying <1%, sulfates <150ppm, and heavy metals <10ppm.
Comparing to competitors: Chinese supply chains often vary pH by 0.3 units due to inconsistent raw materials, leading to 20-30% rework rates. USA buyers face high prices ($1.2-1.5/kg) and shipping delays. Our citric acid anhydrous pH stability cuts these issues, with exports to USA, Brazil, Australia, and more proving 99.8% batch pass rates. Applications span soft drinks (0.3% dosage for tartness), jams (pH stabilization), cleaners (chelating agent), and pharma (effervescent tablets).
Technical deep-dive: Solubility is 147g/100ml at 20°C, increasing to 382g at 100°C. It sequesters metals like Ca2+, Mg2+ via three carboxyl groups, vital for preventing scaling in beverages. Stability data shows no degradation at pH 2-7 up to 40°C. Regulatory compliance: FDA GRAS, EU E330, Kosher/Halal certified. In 2026, with rising demand for clean-label acids (projected 5.2% CAGR per Grand View Research), precise pH is non-negotiable for ROI-focused managers.
Case example: A USA beverage firm switched to our product, achieving uniform pH 3.2 across batches, reducing spoilage by 25% and saving $150K annually. Ready to experience this? Request your free pH test sample today.
Core Pain Points: Why Your Current Citric Acid Anhydrous pH Supply Fails
As a purchasing manager, you demand reliability. Yet, common issues plague citric acid anhydrous pH sourcing:
- High Prices: Competitors charge $1.3+/kg, inflating your COGS by 25% amid 2026 tariffs.
- Low Quality & pH Variability: Off-spec pH (2.0-2.8 drift) causes 15-20% formulation failures, per industry reports.
- High Shipping Costs: Delays from Asia average 45 days, adding $0.2/kg in premiums.
- Inconsistent Purity: Heavy metals >10ppm risk FDA recalls, costing millions.
- Supply Chain Disruptions: 30% of buyers faced shortages in 2025 (USDA data).
- No Customization: Rigid specs ignore OEM needs for pharma/feed blends.
