Cream Of Tartar Nutrition Benefits and Facts

Nutritional summary

Cream of tartar (potassium bitartrate) is a byproduct of the wine-making process that serves as a leavening agent by reacting with sodium bicarbonate (baking soda) to produce carbon dioxide gas .
Because it is a potassium salt of tartaric acid, the ingredient is notably high in potassium, a mineral that many institutional guidelines identify as being under-consumed in modern diets .
No adverse effects on the nutritional quality of food have been identified when cream of tartar is used as a leavening agent or additive .
Safety evaluations of potassium tartrates note that while they are generally recognized as safe, regulatory bodies monitor them for trace impurities of heavy metals like lead and mercury to ensure they remain below health-based exposure limits .

Interesting fact

Known scientifically as potassium bitartrate, this substance crystallizes on the inside of wine barrels during fermentation and was first isolated by a chemist in 1769.
