E325 – Sodium Lactate
AntioxidantsDescription
Hygroscopic, colorless or yellowish, odorless or nearly odorless liquid or solid produced by neutralizing lactic acid
Notes
Sodium lactate is the sodium salt of lactic acid, which is naturally produced when bacteria ferment sugars from sources like corn, beets, or sugarcane. To make this additive, manufacturers combine lactic acid (the same compound that makes your muscles feel sore after exercise) with sodium hydroxide or sodium carbonate. The result is a clear, syrupy liquid that's much less acidic than pure lactic acid. In foods, sodium lactate works as both a humectant and an acidity regulator. As a humectant, it helps foods retain moisture, keeping products like baked goods, processed meats, and cheese fresh and preventing them from drying out. As an acidity regulator, it helps maintain the right pH balance in foods, which is important for both taste and food safety. You'll commonly find it in deli meats, sausages, bread, tortillas, and various packaged snacks. This additive is considered natural since it's derived from fermented plant materials, making it suitable for vegetarian and vegan diets. It's also generally acceptable under most religious dietary laws, including halal and kosher requirements, though individuals following strict dietary guidelines should verify with certifying authorities. Sodium lactate is recognized as safe by food regulators worldwide, though people on sodium-restricted diets should be aware it does contribute to overall sodium intake.
