Consumer Advice
Glucono delta-lactone (GDL) is a food additive made from glucose. It is best known as the coagulant used to make silken tofu, and also serves as an acidulant, leavening agent and sequestrant. In water it slowly hydrolyses to gluconic acid and is a derivative of glucose, so the body metabolises it normally. It has a long history of safe use and is a common, vegan-friendly ingredient.
