D-(+)-Gluconic acid δ-lactone ≥%; CAS Number: ; EC Number: ; Synonym: Glucono delta-lactone, δ-Gluconolactone, 1,2,3,4. Considered a next generation AHA, Glucono Delta Lactone is a Polyhydroxy acid (PHA) that can be found in its natural state (gluconic acid) in honey and royal. Glucono delta lactone is a carbohydrate that contains a lactone formation. In an aqueous solution there is an equilibrium between gluconic acid and the delta.

The pastry is great. Pure GDL is a white odorless crystalline powder. Jungbunzlauer glucono-delta-lactone is lacgone in 25 kg net polyethylene LDPE bags or in kg net polypropylene big bags. When added into an aqueous solution, GdL rapidly dissolves, and subsequently slowly hydrolyses to gluconic acid, thus producing a gentle acidification in the same way as lactic acid-producing bacteria.

The yeast Saccharomyces bulderi can be used to ferment gluconolactone to ethanol and carbon dioxide. It is not made from wheat or from any other gluten-containing grain. New generation of healthy baking powder Published: It is soluble in water, is completely non toxic and is completely metabolised by the human digestive system. Industrial Applications Construction Fine Chemicals. In processed foods, GDL functions as a curing and pickling agent; leavening agent; pH control agent; and sequestrant.

It is metabolized to 6-phospho-D-gluconate; one gram of GDL yields roughly the same amount of metabolic energy as one gram of sugar. In an aqueous solution there is an equilibrium between gluconic acid and the delta and gamma lactones. GdL is a fine, white crystalline powder, freely soluble in water. It is also a complete inhibitor of the enzyme amygdalin beta-glucosidase at concentrations of 1 mM.


As a natural food acid it contributes to the tangy flavor of various foods and since it lowers the pH it also helps preserve the food from deterioration by enzymes and microorganisms.

The equivalent point and the rate of transformation are related to concentration, temperature and pH-value. Glucono delta-lactone GDLalso known as gluconolactone, is a food additive with the E number E [3] used as a sequestrantan acidifier[4] or a curingpicklingor leavening agent. From Wikipedia, the free encyclopedia. Special granulations are available upon request.

Retrieved from ” https: Glucono-1,5-Lactone or GdL is a neutral cyclic ester of gluconic acidproduced with the acid by fermentation of glucose.

So it is used as a slow release acidifier. Two properties set GdL apart from other common acids and are the base of its application range: Glucono Delta Lactone is packaged in 25kg lined, multi-walled paper bags.

During its hydrolysis, the initial sweet taste of GdL becomes only slightly acidic, making the final lactohe of an aqueous solution of GdL much less tart than the one of other acidifiers. Product Support Request a Sample. Utilizamos cookies para optimizar nuestro sitio web. In large scale commercial manufacturing GDL is widely used in products such as tofu, honey, fruit juices and wine.


Glucono delta-lactone

In food manufacturing, acidulants are used to reduce the pH of the food, retarding spoilage GDL can be used as a natural preservative in some circumstancesas well as to prevent the discolouration of the final food product. Retrieved 28 October It is a lactone of D – gluconic acid. These delt available with or without a dessicant bag.

It is metabolized to glucose; one gram of GDL is equivalent to one gram of sugar. GeneralGlucono Delta Lactone.

delta-Gluconolactone | C6H10O6 – PubChem

Journal of Dairy Science. GDL is commonly found in honey, fruit juices, and wine.

C 6 H 10 O 6 Melting Point: GDL has been marketed for use in feta cheese. Gluconl toxic, it is completely metabolised in the body like a carbohydrate. Views Read Edit View history. An Encyclopedia of Chemicals, Drugs, and Biologicals 13th ed. In yeasted products, the yeast metabolises sugars during the proving process and excretes carbon dioxide to achieve the same effect.

What is Glucono Delta Lactone?

Gluconolactone | C6H10O6 – PubChem

It is practically odourless and has a slightly sweet taste. Glucono delta lactone is a carbohydrate that contains a lactone formation.

Being acidic, it adds a tangy taste to foods, though it has roughly a third of the sourness of citric acid. Through its slow hydrolysis to gluconic acid, it ensures a progressive and continuous decrease of pH to equilibrium. The pH value greatly affects culture growth.
