• pH Value: 2.2–2.5 (1% aqueous solution)

Product Description

Visually presenting as a translucent, colorless crystalline powder, our anhydrous citric acid offers a uniquely dry, free-flowing texture. When handled on the production floor, the granules emit a faintly tart, clean aroma, indicative of its pure composition. Its refined physical state guarantees rapid dissolution, blending uniformly into dry formulations without leaving gritty residues or causing mechanical blockages in industrial mixers.

The absence of crystalline water in this specific variant translates into profound stability for moisture-sensitive applications. By eliminating intrinsic water molecules, the compound actively resists clumping, maintaining a loose, sand-like consistency even when exposed to ambient factory humidity. This characteristic drastically reduces machine downtime caused by clogged hoppers and ensures a smooth, continuous flow during automated packaging processes.

Beyond its physical handling advantages, this acidifier acts as a potent chelating agent and preservative. It binds effectively with trace metals, neutralizing oxidative degradation that can compromise the shelf life and sensory profile of finished goods. Procurement teams value this dual functionality, as it streamlines inventory by replacing multiple single-purpose additives with one highly efficient, multi-functional ingredient.

Product Benefits

Exceptional Low Hygroscopicity: Operating in tropical or high-humidity manufacturing zones (relative humidity > 70%) often leads to ingredient clumping. This moisture-free variant aggressively resists ambient moisture absorption, ensuring the powder remains highly flowable. This translates to fewer production interruptions and exact dosing in automated weighing systems.

Superior Thermal Stability: Designed to withstand intense processing conditions, the chemical integrity of this acidifier remains intact at elevated temperatures up to 175°C (with decomposition starting only above this threshold). It will not prematurely degrade or caramelize during high-heat applications like extrusion, commercial baking, or spray drying, preserving the intended tartness and color of the final output.

Optimized Cost Efficiency: Achieving the desired flavor profile requires significantly less volume compared to alternatives. By delivering equivalent sourness to tartaric acid at a 15% lower dosage—for example, 0.5g of anhydrous citric acid achieves the same sourness as 0.59g of tartaric acid—formulation costs are notably reduced, allowing procurement departments to maximize raw material budgets.

Precision Particle Sizing for Easy Handling: Supplied in a meticulously controlled 30–100 mesh range (common specifications include 40–60 mesh for instant mixes and 80–100 mesh for powdered beverages), the granules are engineered for rapid, homogeneous dispersion. This uniform particle size prevents stratification during transit and guarantees a consistent flavor release in every batch.

Rigorous Impurity Control: Manufactured to exceed standard purity benchmarks, the extraction process leaves zero residual solvents or unwanted fermentation by-products. With heavy metal concentrations (lead, mercury, cadmium) strictly maintained at ≤ 0.1 ppm, the ingredient aligns perfectly with the stringent safety requirements of pharmaceutical-grade standards.

Usage

Dry Powdered Foods & Beverages: Essential for instant drink formulations (powdered coffee, chocolate drinks), cake premixes, and dry seasoning blends at a precise dosage of 0.2%–0.8%. Its completely dry nature prevents premature chemical reactions with leavening agents. In instant soup mixes, it provides a sharp, clean bite that elevates umami notes while balancing heavy sodium profiles, dissolving instantly upon contact with hot water.

Confectionery & Sugar-Free Gum: Acts as a critical flavor enhancer and microbial inhibitor in chewing gum production (dosage: 0.3%–0.5%). The anhydrous form is specifically chosen here because introducing extraneous moisture could degrade the gum base’s elasticity over time. It delivers a prolonged, refreshing tartness while safeguarding the product against mold proliferation during extended warehouse storage.

Meat Processing & Preservation: Applied as an antimicrobial surface spray (5% concentration dilute solution) for fresh poultry such as chicken and turkey. By safely lowering the surface pH, it creates an inhospitable environment for pathogens like Salmonella. This intervention extends the cold storage viability of fresh cuts by 5–7 days, significantly reducing spoilage-related financial losses.

Pharmaceutical Excipients: A foundational component in the manufacturing of effervescent tablets (e.g., vitamin C tablets). When combined with sodium bicarbonate, it triggers a rapid, controlled release of carbon dioxide upon hydration, improving tablet dissolution and palatability. The ultra-low moisture content is vital to prevent premature effervescence inside blister packaging.

FAQ

Q: What’s the key difference between anhydrous citric acid and monohydrate citric acid?

A: Anhydrous citric acid contains no crystalline water (H₂O), while monohydrate contains one molecule of crystalline water per molecule of citric acid. This makes the anhydrous form preferable for dry mixes (e.g., cake powders, instant drinks) as it avoids clumping; the monohydrate is better suited for liquid-based products (e.g., juices, sauces) where moisture is less of a concern.

Q: Can it be used in pharmaceutical formulations beyond effervescent tablets?

A: Yes, its low bacterial endotoxin content (< 0.5 IU/mg) qualifies it for use in oral suspensions, syrups, and even injectable formulations (as a pH adjuster), complying with USP-NF pharmaceutical standards.

Q: Is the 25kg packaging recyclable or reusable?

A: The kraft paper outer bag is fully recyclable (meets EN 13432 compostability standards), while the PE liner can be cleaned and reused for storing dry, non-food items (e.g., hardware, craft supplies). Bulk packaging (500kg super sacks) is also available for large-scale manufacturers.

Q: Can the particle size be customized to match our existing processing equipment?

A: Yes, we understand that different mixers require specific granule sizes to prevent segregation. We offer precise screening options ranging from 30 to 100 mesh, allowing you to select the exact specification that ensures homogeneous distribution within your specific product matrix.

Q: What is the standard lead time for large-scale procurement orders?

A: Thanks to our substantial warehousing capacity and optimized production scheduling, standard bulk orders are typically processed and ready for dispatch within 7 to 15 days. We also offer customized inventory holding agreements for partners requiring just-in-time delivery schedules.
