Consumer Advice
Tartaric acid is a naturally occurring organic acid mainly obtained from grapes (a by-product of winemaking). It is used as an acidity regulator, a leavening ingredient and an antioxidant enhancer in baking powder, jellies, confectionery, wine and drinks. It has a high safety margin and is harmless at authorised levels. The very few who follow strict plant-based or religious dietary rules may note its grape origin, but it has no health effects.
