Dung Dịch Natri Lactate is one of the most versatile organic acid salt ingredients in food processing, with applications spanning antimicrobial preservation, moisture retention, mineral fortification, and shelf-life extension. Its primary role in meat and poultry is inhibition of Listeria monocytogenes and Clostridium botulinum through water activity reduction (a_w lowering) and subtle bacteriostatic effects, while simultaneously enhancing flavor by reducing salty/bitter notes and boosting savory perception. In confectionery and dairy it functions as a humectant, preventing moisture loss and texture degradation.
In cosmetics it serves as a skin-hydrating agent in the natural moisturizing factor (NMF) composition. Typical commercial grade is a 60% solution with pH 6.5–8.5. It is GRAS under FDA 21 CFR 184.1768 and approved as E325 globally. Use levels in RTE meat products: 1.0–4.8% of finished product weight (USDA FSIS validated).
