Potassium lactate is a compound with formula KC3H5O3. It is the potassium salt of lactic acid and appears as a clear, hygroscopic, syrupy liquid suspension that is typically 60% solids. [1] The substance can be concentrated to contain up to 78% solids. [2] It is produced by neutralizing lactic acid, which is fermented from a sugar source. It has E number E326.
Potassium lactate is commonly used in meat and poultry products to extend shelf life and increase food safety, as it has a broad antimicrobial action and is effective at inhibiting most spoilage and pathogenic bacteria. [3]
Potassium lactate is used as an extinguishing medium in First Alert Tundra fire extinguishers. [4]
