What is E334 (Tartaric Acid)?
E334 is the E-number for tartaric acid, one of the antioxidants group of food additives (E300–E399). Additives in this group stop fats and oils turning rancid and protect food colour and flavour. Extracted from grape by-products of winemaking or produced synthetically. Like every E-number, E334 has been evaluated and authorised for use in food in the European Union — the 'E' literally stands for Europe, and a number is only granted after a safety assessment. That authorisation doesn't mean every additive suits every diet or that all concerns are settled, which is why we break down the safety, vegan, vegetarian and halal status of E334 in detail below.
