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.

Glucono Delta Lactone

It is metabolized to glucose; one gram of GDL is equivalent to one gram of sugar. Adding value to surimi based products Published: What is Glucono Delta Lactone?

Glucono delta lactone GDL is a natural constituent of many foods. Gluconates Gluconates in food applications. Being acidic, it adds a tangy taste to foods, though it has roughly a third of the sourness of citric acid.

GdL is a fine, white crystalline powder, freely soluble in water. Product Support Request a Sample. In large scale commercial manufacturing GDL is widely used in products such as tofu, honey, fruit juices and wine.

Glucono-1,5-Lactone or GdL is a neutral cyclic ester of gluconic acidproduced with the acid by fermentation of glucose. New generation lactond healthy baking powder Published: When added into an aqueous solution, GdL rapidly delra, and subsequently slowly hydrolyses to gluconic acid, thus producing a gentle acidification in the same way as lactic acid-producing bacteria.


General information Glucono-1,5-Lactone or GdL is a neutral cyclic ester of gluconic acidproduced with the acid by fermentation of glucose. The rate of hydrolysis of GDL is increased by heat and high pH. Industrial Applications Construction Fine Chemicals.

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

It is soluble in water, is completely non toxic and is completely metabolised by the human digestive system. From Wikipedia, the free encyclopedia. Non toxic, it is completely metabolised in the body like a carbohydrate.

In solution both gluconic acid and GdL are always in balance. Personal Care Comprehensive solutions for personal care. Glucono Delta Lactone, often abbreviated GDL, is a naturally occurring food ingredient and is one of a class of ingredients known as acidulants.

Glucono Delta Lactone should be stored at room temperature in a g,ucono location.

During its hydrolysis, the initial sweet taste of GdL becomes only slightly acidic, making the final flavour of an aqueous solution of GdL much less tart than the one of other acidifiers. Upon addition to water, GDL is partially hydrolysed to gluconic acid, with the balance between the lactone form and the acid form established as a chemical equilibrium. This page was last edited on 6 Decemberlavtone Glucono delta-lactone GDLalso known as gluconolactone, is a food additive latcone the E number E [3] used as a sequestrantan acidifier[4] or a curingpicklingor leavening agent.


Find more literature in: 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 lxctone the discolouration of the final glucino product. Retrieved 28 October 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.


Pure GDL is a white lqctone crystalline powder. It can be found in honey, fruit juices, wine and many fermented products. The yeast Saccharomyces bulderi can be used to ferment gluconolactone to ethanol and carbon dioxide.
