Is e336 vegan?

E336 is the food additive code for potassium tartrates, a category of salts that includes monopotassium tartrate, commonly known as cream of tartar, and dipotassium tartrate. This ingredient is obtained as a natural byproduct of winemaking. During the fermentation of grape juice, naturally occurring tartaric acid reacts with potassium to form crystalline sediments inside storage casks. These crystals are harvested, purified, and milled into a fine white powder for commercial food use.

Food manufacturers use E336 as an acidity regulator, leavening agent, and stabilizer. It appears frequently on ingredient labels for baking powder, baked goods, sugar confectionery, dessert toppings, and carbonated beverages. E336 is classified as vegan because its source material is exclusively botanical and mineral in origin. No animal tissues, byproducts, or animal-based processing aids are involved in its extraction or manufacturing, making it suitable for a plant-based diet.
