Useful:

• Description: Potassium lactate is a compound with formula KC3H5O3, or H3C-CHOH-COOK. It is the potassium salt of lactic acid. It is produced by neutralizing lactic acid which is fermented from a sugar source. It has E number "E326". Potassium lactate is a liquid product that is usually 60% solids but is available at up to 78 % solids. 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. Potassium lactate is also used as an extinguishing media in the First Alert Tundra fire extinguishers.
• Uses: Potassium DL- Lactate is used in preparation of high solids and high protein lactose-free aseptic milk concentration and milk powders with forward osmosis. Potassium Lactate is a flavor enhancer that is the potassium salt of lactic acid. it is a hygroscopic, white, odorless solid and is prepared commercially by the neutralization of lactic acid with potassium hydroxide. it is used as a flavoring agent and enhancer in some meat and poultry products, a humectant, and a ph control agent.
