Suolaaine

Suolaaine, also known as sodium lactate, is the sodium salt of lactic acid. It is a white, crystalline powder that is soluble in water and alcohol. In the food industry, suolaaine is commonly used as a preservative, flavoring agent, and humectant. It helps to extend the shelf life of products by inhibiting the growth of bacteria and molds. As a flavoring agent, it contributes a mild, salty, and slightly tangy taste. Its humectant properties allow it to retain moisture, which is beneficial in baked goods and meat products, preventing them from drying out.

Beyond food applications, suolaaine finds use in the cosmetic and pharmaceutical industries. In cosmetics, it acts as a moisturizer and pH adjuster in skincare products like lotions and creams. Its ability to attract and hold water makes it an effective ingredient for hydrating the skin. In pharmaceuticals, it can be found in intravenous solutions and as an active ingredient in some topical medications. The production of suolaaine typically involves the neutralization of lactic acid with a sodium source, such as sodium hydroxide or sodium carbonate. It is generally recognized as safe (GRAS) by regulatory bodies for its intended uses in food and other applications.
