Natural preservative for meat products, pH regulator & moisturizer for cosmetics, quality improver for flour products, salt reduction ingredient.
Potassium Lactate (CAS 996-31-6) is the potassium salt of lactic acid. It appears as a colorless or slightly yellowish transparent viscous liquid, readily soluble in water, with excellent moisturizing properties, pH regulation ability and antibacterial synergistic effect.
As a generally recognized as safe (GRAS) food additive and multifunctional raw material, potassium lactate is widely used in meat processing (preservation and fresh-keeping), flour products (quality improvement) and personal care products (natural moisturizing factor).
As a source manufacturer, we provide food grade, cosmetic grade and other multi-specification products, supporting stable bulk supply.

Key Application
Meat Product Preservation:
Potassium Lactate effectively inhibits the growth of pathogenic and spoilage bacteria such as Listeria and Lactic Acid Bacteria. Its antibacterial mechanism works by reducing water activity and affecting proton permeability of cell membranes to acidify intracellular structures. Studies show that adding 2–3% Potassium Lactate in frankfurters significantly suppresses microbial growth and extends shelf life by 75%–125%.
Sodium Chloride Replacement:
As a key component in salt-reduction solutions, Potassium Lactate can replace part of sodium chloride, maintaining texture and sensory properties of meat products while significantly reducing sodium content.
Flour Product Improvement:
Used in fresh noodles, frozen noodles, bread and other flour products to enhance flavor, retain moisture, and improve stability and safety.
Flavoring & Emulsification:
Used as a flavor enhancer, emulsifier, humectant, pH regulator, aroma booster and buffer, mainly in jams, jellies, marmalades, ice cream and other products.
