Cream of tartar (CAS 868-14-4, E336), also known as potassium bitartrate, is a natural byproduct of winemaking that crystallizes in wine casks during fermentation.
Application: (1) Baking: A primary ingredient in baking powder when mixed with baking soda to provide lift. (2) Confectionery: Used to make smooth icings, candies, and syrups by preventing grittiness. (3) Culinary: Essential for increasing the volume and heat tolerance of whipped egg whites in meringues and soufflés. (4) Industrial: Utilized in winemaking for pH regulation and in cosmetics as a texture enhancer.
Features: (1) Acidic Nature: Acts as a mild acid to activate leavening agents. (2) Stabilizer: Exceptional at stabilizing protein structures, particularly in foams. (3) Crystallization Inhibitor: Prevents sugar from binding together into large crystals.
