Potassium Lactate
Potassium Lactate is the potassium salt of lactic acid (C₃H₅KO₃, CAS No. 996-30-5), produced via industrial bio-fermentation and precise neutralization. It functions primarily as an effective antimicrobial agent, shelf-life extender, pH regulator, and moisture-retaining humectant.
Operating dedicated multi-ton reactor capacity with closed-loop evaporation and automated filtration systems, we supply food, cosmetic, and industrial-grade Potassium Lactate solutions conforming to international purity standards. Our manufacturing process utilizes stainless-steel isolation and multi-stage ion exchange to maintain low heavy metal profiles and batch-to-batch consistency for industrial operations.

Applications
Meat & Poultry Processing: Inhibits the growth of Listeria monocytogenes and other pathogens in ready-to-eat (RTE) meat products, extending shelf life without modifying natural flavor profiles.
Sodium Reduction: Functions as an effective substitute for sodium chloride and sodium lactate, lowering total sodium content in processed foods while preserving water-holding capacity.
Personal Care & Cosmetics: Acts as a high-efficiency humectant and pH buffer in skin lotions, facial cleansers, and hair care formulations.
Industrial & Chemical: Utilized as a biodegradable de-icing agent component and chemical intermediate in specialized synthesis.
Product Grades & Options
Liquid 60% (Food & Industrial Grade): Standard concentration optimized for direct dosing in meat injection fluids and beverage formulations.
Liquid 88% (Concentrated Grade): High-concentration formulation designed to reduce freight volume and support customized industrial blending.
Customization: Tailored pH adjustments and specific heavy metal threshold limits available upon contractual request.
Quality Control & Documentation
Our manufacturing facility operates under ISO 9001, FSSC 22000, and GMP standards.
In-House Testing: Every production lot is verified via ICP-OES for heavy metal control, high-performance liquid chromatography (HPLC) for assay validation, and automated titration for pH stability.
Traceability: Full lot backward and forward traceability maintained from raw material fermentation to final packaging.
Documentation Support: Each shipment includes a Certificate of Analysis (COA). Technical Data Sheets (TDS), Safety Data Sheets (SDS), Kosher, and Halal certificates are provided upon request.
Packaging & Storage
Standard Packaging:
1.25 kg / 250 kg high-density polyethylene (HDPE) drums.
2.1,200 kg Intermediate Bulk Container (IBC) totes.
3.Bulk tanker delivery available for high-volume manufacturing plants.
Storage Conditions: Store in a cool, dry, well-ventilated area away from direct sunlight. Keep containers tightly sealed to prevent moisture absorption or microbial contamination.
Shelf Life: 24 months from the date of manufacture in original unopened packaging.
FAQ
Q: What is the operational difference between Potassium Lactate 60% and 88%?
A: The 60% grade contains 60% active potassium lactate and 40% water, formulated for direct incorporation into meat brine. The 88% grade is a concentrated solution offering reduced freight costs and greater flexibility for industrial blenders.
Q: Does your Potassium Lactate contain allergens or GMO materials?
A: No. Our product is derived from non-GMO carbohydrate fermentation sources and is free from major food allergens, including gluten, dairy, tree nuts, and soy.
Q: Can Potassium Lactate completely replace sodium lactate in meat applications?
A: Yes. It delivers equivalent antimicrobial efficacy and moisture retention while fulfilling low-sodium dietary labeling requirements.
Q: What is the minimum order quantity (MOQ) for bulk shipments?
A: Standard MOQ is one pallet (typically 20 x 25 kg drums or 1 x 1,200 kg IBC tote). Trial sample quantities (500 g - 1 kg) are available for R&D evaluation.
Q: What shipping terms and lead times do you support?
A: We routinely support FOB, CIF, and DDP terms via ocean freight and air express. Standard stock items ship within 5 to 7 business days following order confirmation.
Q: How do you ensure batch-to-batch consistency for heavy metal impurities?
A: We utilize multi-stage ion-exchange resin purification and membrane filtration during processing, followed by mandatory ICP-OES verification for every individual production lot.
