Physical and Chemical Properties
Food Grade Zinc Citrate is supplied as a white, odorless powder with limited water solubility and high stability in dry form.
Solubility Profile: Slightly soluble in water; readily soluble in dilute mineral acids and alkaline hydroxide solutions.
Organoleptic Quality: Clean taste profile with significantly less astringency than zinc sulfate, making it preferred for chewables and dry blends.
Formulation Considerations: In aqueous liquid formulations, complete dispersion or dissolution depends on system pH, shear rate, and processing temperature.
Quality Control & Documentation
Jiangsu Kolod enforces strict batch-level quality control. Every production lot is tested against defined specifications prior to release, with key parameters verified on the batch Certificate of Analysis (COA).
Key Testing & Control Parameters
• Assay & Elemental Zinc: Chemical titration and identity verification (≥31.3% Zn content).
• Heavy Metal Profiling: Quantitative analysis for Arsenic (As), Lead (Pb), Cadmium (Cd), and Mercury (Hg) via ICP-MS / AAS.
• Physical & Chemical Criteria: Loss on drying (LOD), water content, pH, bulk density, and sieve analysis (mesh size).
• Microbiological Screening: Total Plate Count, Yeast & Mold, Salmonella, and E. coli.
Document Package for Vendor Qualification
We supply a regulatory dossier to support raw material approval, market compliance, and customer audits:
• Technical Files: Batch COA, Technical Data Sheet (TDS), Product Specification Sheet, GHS-compliant SDS.
• Compliance Declarations: Non-GMO, Allergen-Free, BSE/TSE-Free, Residual Solvents, and Non-Irradiation statements.
• Facility Certifications: ISO 9001, ISO 22000 / FSSC 22000, HACCP, Halal, and Kosher.
Traceability & Retain Samples
• Batch Traceability: Every lot is assigned a unique batch code mapped to raw material inputs, reactor processing logs, milling parameters, and packaging inspection records.
• Retain Sample Protocol: Archive samples from every commercial batch are stored in climate-controlled conditions for post-market reference and comparative quality evaluation.
Packaging, Storage, and Transportation
Standard Packaging: 25 kg net weight per bag.
• Inner Packaging: Food-grade polyethylene (PE) bag to protect against moisture ingress.
• Outer Packaging: Compound plastic woven bag for transport durability.
Storage Conditions: Store in tightly closed original packaging in a cool, dry, well-ventilated warehouse away from heat sources, direct sunlight, and moisture.
Handling & Transport: Handle with care to prevent package tearing or leakage. Transport in clean, dry vehicles in compliance with standard food ingredient handling guidelines.
Frequently Asked Questions
Q: Is Food Grade Zinc Citrate suitable for beverage formulations?
A: Because it is slightly soluble in neutral water, its suitability in clear liquids depends on formulation pH, mixing conditions, and turbidity requirements. Testing is recommended before scale-up.
Q: Can Kolod provide a COA before bulk order placement?
A: Yes, representative product specifications and batch Certificates of Analysis (COA) are available upon request for technical evaluation and supplier qualification.
Q: What details are required to request a quotation?
A: Please provide your target order quantity, required packaging format, destination country/delivery terms, and any specific specification or regulatory requirements.
