Citric Acid Monohydrate Characteristics
Crystalline Form: Colorless or white crystalline solid supplied in granular form, with water of crystallization reflected in the specified moisture range.
Acidulant Function: Provides acidity in food formulations and can be used where pH adjustment or a sour taste is required.
Formulation Role: Its crystalline form allows use in both dry blends and solution-based formulations, depending on the required dissolution and processing method.
Solubility & Stability: Dissolves readily in water and ethanol systems under standard ambient processing temperatures.
Particle Size & Applications
Particle Handling: The 8–40 mesh grade provides a relatively coarse particle form that can be suitable for dry blending and bulk powder handling applications.
Food & Beverage Processing: Applied in dry powder drink mixes and seasoning salts where uniform dry blending prevents caking.
Preservation Mechanisms: Lowers formulation pH to suppress bacterial growth in canned foods, jams, and jellies.
Industrial Adjustments: Utilized to control acidity in chemical cleaning formulations and adjust fermentation pH levels.
Regulatory & Compliance
Quality & Compliance: The product can be supplied against applicable BP, USP, FCC and E330 specifications. Batch-specific COAs and supporting compliance documents can be provided upon request.
Global Food Directives: Approved for international food and beverage processing under FCC and European E330 statutory limits.
Traceable Certifications: Documentation packages include official declarations of conformity for statutory chemical and food-grade safety audits.
Batch Quality Control
Analytical Testing: Each production lot undergoes verification for identity, solution clarity, and color compliance.
Control Metrics: Routine checks monitor oxalate, sulphate, and readily carbonisable substance parameters per lot.
Conformity Verification: Final release requires meeting all established pharmacopoeia and chemical purity limits.
Supply Chain & Logistics Capabilities
Export Packaging: Packed in moisture-resistant 25kg multi-layer paper bags or woven bags lined with polyethylene film to prevent caking during ocean transit.
Shipping Terminals: Dispatched directly through Qingdao Port, ensuring immediate access to major international shipping routes and container consolidation facilities.
Volume & MOQ: Flexible wholesale order quantities scaled for container load (FCL) or palletized less-than-container load (LCL) distribution.
Fulfillment Documentation: Complete logistics paperwork provided per shipment, including commercial invoices, packing lists, and bills of lading tailored for customs clearance.
