Product Details

D-(+)-Glucono-1,5-lactone CAS#90-80-2

Delta-Gluconolactone (GDL) is a lactone of the D-gluconate. It is a natural constituent of many foods. It can be found in honey, fruit juices, wine and many-fermented products1-3. It is used as a food additive with the E number E575 used as a sequestrant, an acidifier (it lower the pH and also help preserve the food from deterioration by enzymes and organisms), or a curing, pickling, or leavening agent. GDL has been marketed for use in feta cheese. GDL is neutral, but hydrolyses in water to gluconic acid that is acidic, adding a tangy taste to foods, though it has roughly a third of the sourness of citric acid. It can be used as nutritional supplement in beverage such as in Instant Drinks, Syrups, RTD Tea and Coffee, Sports and Energy Drinks, Waters.

Product Application of D-(+)-Glucono-1,5-lactone CAS#90-80-2

(GDL) An acidulant. It hydrolyzes to form gluconic acid in water solution and thereby creates the desired pH. The rate of acid formation is affected by temperature, concentration, and the pH of the solution. It has low acid release at room temperature and accelerated conversion into gluconic acid at high temperatures. It is readily soluble with a solubility of 59 g in 100 ml of water at 20°C. It functions as a leavening agent, acidulant, curing and pickling agent, and pH control agent. It is comparatively less tart/sour than other food acids. It is used in baked goods, fish products, desserts, and dressings.
