Glucono-delta-lactone

Glucono-delta-lactone is a natural ester of gluconic acid, which is formed by the fermentation of glucose. This process is done by evaporation, and produces a white, odourless, crystalline powder that is used in foods as an acidity regulator, sequestrant, and leavening agent. It can also be used to add a tangy tasted to foods, and as an artificial sweetener base.http://www.creative-enzymes.com/product/Gluconodeltalactone_648.html
