Potassium lactate

Potassium lactate is a chemical compound used in a variety of applications, including as a food additive, a preservative, and a humectant. It is a potassium salt of lactic acid, and is typically a clear, colorless liquid or a white, crystalline solid.

Chemical properties

Potassium lactate has the chemical formula C3H5KO3. It is highly soluble in water and is stable under normal conditions. It has a slightly salty, bitter taste and is odorless. It is produced by neutralizing lactic acid with a high purity potassium source.

Uses

Food additive

In the food industry, potassium lactate is used as a food additive and is designated by the E number E326. It is used as a preservative, acidulant, and flavor enhancer. It can also be used to control the pH of food products and to extend their shelf life. It is commonly found in meat and poultry products, as it helps to improve their water holding capacity and reduce the growth of pathogenic bacteria.

Other uses

In addition to its use in the food industry, potassium lactate is also used in other industries. For example, it is used in the production of cosmetics and personal care products, where it acts as a humectant, helping to keep products moist. It is also used in the pharmaceutical industry, where it is used as a buffering agent in medications.

Safety

Potassium lactate is generally recognized as safe (GRAS) by the Food and Drug Administration (FDA). However, as with any food additive, it should be used in moderation. Some people may experience allergic reactions to potassium lactate, including skin irritation or gastrointestinal distress.
