Is e370 vegan?

E370 is the E-number for 1,4-heptonolactone, an organic chemical compound that functions as an acidity regulator, stabilizer, and sequestrant in food products. It is synthetically manufactured through multi-step chemical synthesis, typically produced from the cyanohydrin reaction of glucose or through the oxidation and lactonization of heptonic acid derivatives. These industrial processes rely on plant-derived sugars or synthetic chemical precursors. Food manufacturers utilize the additive in items such as processed convenience foods, baked goods, powdered drink mixes, and confectionery to control acidity and prevent discoloration caused by trace metals.

E370 is vegan because its production relies entirely on synthetic, plant, or mineral materials. No animal tissues, dairy, fats, or animal-derived enzymes are involved in its chemical synthesis or refining stages. Because it contains no animal products and requires no animal processing aids, E370 is fully compatible with a vegan diet.
