Sodium lactate is the sodium salt of lactic acid, commercially available as a clear, slightly viscous liquid concentrated to 60% solids by weight in purified water. It is widely used in food manufacturing for its strong antimicrobial and humectant properties, helping extend shelf life and improve product quality across meat, poultry, and seafood applications.
For food producers operating under kosher guidelines, sodium lactate is a key ingredient that must carry proper rabbinical certification. Major producers such as Galactic and Hawkins supply sodium lactate with Orthodox Union (OU) kosher certification, classified as Pareve, confirming the product contains no meat or dairy derivatives.
How Sodium Lactate Earns Kosher Pareve Status
Sodium lactate is produced through the fermentation of sugars, followed by neutralization with sodium hydroxide to form the lactate salt. Despite having “lactate” in its name, the ingredient is not derived from milk. The fermentation-based production process uses plant-derived carbohydrates as the starting material.
The Orthodox Union certifies sodium lactate produced by companies like Galactic (Belgium) under multiple UKD-IDs, requiring the OU symbol on packaging. Products shipped in bulk must use OU-approved carriers. This dual-tier system ensures kosher integrity whether the product is packaged at the source or transported to a secondary facility.
Antimicrobial and Shelf-Life Benefits
In meat, poultry, and seafood products, sodium lactate inhibits the growth of harmful microorganisms including Listeria monocytogenes and Clostridium botulinum. It extends shelf life significantly while also reducing moisture loss during cooking and storage. These functional benefits make it one of the most cost-effective preservatives available to food manufacturers.
Sodium lactate also acts as a pH stabilizer, preventing spoilage caused by undesirable shifts in acidity. Its mild saline taste can enhance the natural flavor of processed meats without introducing off-notes, making it a dual-purpose ingredient that improves both safety and sensory qualities.
Product Specifications and Packaging
Commercial sodium lactate 60% is colorless, odorless, and stable with an indefinite shelf life under normal storage conditions. It is allergen-free, containing no dairy, egg, wheat, soy, tree nuts, peanuts, fish, or shellfish. U.S.-manufactured products like Ultralac SL-60 are considered GRAS (Generally Recognized as Safe) under FDA regulations.
Standard packaging includes 55-gallon polyethylene drums (approximately 600 lbs. net), 2,850 lb. intermediate bulk containers, and bulk tankers. The product should be stored unopened under dry conditions at ambient temperatures. Both Kosher-Pareve and Halal certifications are commonly available from domestic suppliers.
