Potassium Gluconate Manufacturer for Food, Supplement and Feed Applications
Potassium gluconate (CAS 299-27-4) is the potassium salt of gluconic acid. It is used as a potassium source in dietary supplements, beverage powders, fortified foods, and selected feed formulations. Buyers should qualify the material against the intended use, destination-market rules, elemental potassium target, sensory requirements, solubility, impurity limits, and supporting batch documents.
WIS Biotech manufactures food-grade and feed-grade potassium gluconate in Shandong, China. Since 2015, our gluconate facility has supplied ingredient distributors, contract manufacturers, food and beverage producers, and premix buyers in more than 80 countries. Current specifications, SDS, recent batch COA, applicable certificates, samples, and destination-based quotations are available on request.
Potassium Gluconate Applications
Dietary Supplements and Electrolyte Blends
Potassium gluconate can be formulated into tablets, capsules, gummies, sachets, and multi-mineral products. Formulators should calculate the required ingredient weight from the approved batch specification and verify serving size, sensory performance, compatibility, labelling, and local limits in the finished product.
Sports, Hydration and Functional Beverages
Its water solubility and sensory profile make potassium gluconate a candidate for powdered and liquid beverage systems. Final clarity, flavour, and stability depend on concentration, pH, temperature, processing sequence, acids, sweeteners, stabilisers, and other minerals. WIS can provide samples and available technical data for qualification trials.
Food Fortification and Sodium-Reduction Projects
Potassium gluconate may be evaluated as a potassium source and, in some formulas, as part of a sodium-reduction strategy. It does not provide a one-for-one functional replacement for sodium chloride, so sensory, preservation, texture, and regulatory effects must be tested in the finished food.
Feed and Premix Use
Feed-grade potassium gluconate is supplied for electrolyte and mineral premixes subject to the buyer’s formula, species, inclusion level, and local feed rules. Feed buyers should confirm the grade, production scope, specification, and applicable certification documents before approval.
Potassium Gluconate Supplier: Procurement Checklist
- Define the application: state the product type, destination market, required grade, and target elemental potassium contribution.
- Approve the specification: compare assay, potassium content, pH, solubility, and impurity limits with a recent batch COA.
- Confirm documents: request the current specification, SDS, COA, origin documents, and certificates applicable to the selected grade and site.
- Set commercial terms: provide trial and annual volume, packaging, destination, requested delivery date, and Incoterm.

Packaging and Supply
Standard packaging is 25 kg net multi-layer kraft paper bags with an inner PE liner. FIBC options may be available for approved orders. Store sealed in a cool, dry, well-ventilated place away from direct sunlight and incompatible materials.
Commercial MOQ: 500 kg. Qualification samples of 1–5 kg are available subject to approval and stock. Standard lead time is generally 7–14 business days after order confirmation; final availability, loading, freight basis, and delivery schedule are confirmed in the quotation.
Quality and Documentation
Each commercial shipment is supported by a batch COA and SDS, with origin and shipping documents prepared for the agreed transaction. Controlled copies of applicable quality, food-safety, Halal, Kosher, and feed-scope certificates are available on request. Buyers should verify that each certificate covers the selected grade, production site, validity period, and destination-market requirement. WIS Biotech does not offer pharmaceutical-grade potassium gluconate.
Frequently Asked Questions
How does potassium gluconate compare with potassium chloride?
Both supply potassium, but they differ in elemental potassium concentration, taste, ionic contribution, serving size, and formula behaviour. Potassium gluconate may suit products where its sensory and solubility profile is useful, while potassium chloride may suit other cost or concentration targets. The final choice should follow bench trials and the applicable finished-product rules.
How much elemental potassium does WIS Biotech specify?
The current page specification states 16.5%–17.5% potassium and 97.0%–103.0% assay on a dried basis. Formulators should use the approved specification and batch COA for dosing calculations and verify serving-level labelling under the destination-market rules.
Is potassium gluconate suitable for beverage applications?
It is freely soluble in water and can be evaluated for powdered and liquid beverages. Finished-product clarity, flavour, and stability must be confirmed at the intended concentration and pH because acids, sweeteners, stabilisers, temperature, and other minerals can affect performance.
What is the MOQ and lead time for potassium gluconate?
The commercial MOQ is 500 kg. Qualification samples of 1–5 kg are available subject to approval and stock. Standard lead time is generally 7–14 business days after order confirmation, with final timing stated in the quotation.
Is potassium gluconate permitted as an EU food additive?
Potassium gluconate is listed as E577 in the EU food-additive framework. Permission is not blanket approval for every food: the finished-product manufacturer must confirm the relevant food category, purpose, conditions of use, specifications, and current consolidated legislation before placing a product on the market.
Are Halal and Kosher documents available?
Controlled copies of applicable Halal and Kosher certificates are available on request. Buyers should confirm certificate scope against the selected grade, production site, validity period, and destination-market requirements before commercial approval.
Request a Potassium Gluconate Quote
Request a quote or qualification sample and include the application, grade, target specification, trial and annual volume, packaging, destination, and Incoterm. Ask for the current specification, SDS, recent batch COA, and applicable certificates.
