Glucono delta lactone suppliers & manufacturers

Glucono delta lactone (GDL)

also known as gluconolactone, is a food additive with the E number E575 used as a sequestrant, an acidifier,or a curing, pickling, or leavening agent. It is alactone of D-gluconic acid. Pure GDL is a white odorless crystalline powder.

GDL is commonly found in honey, fruit juices, personal lubricants, wine and has been marketed for use in feta cheese.

For fish and prawn 0.1g/kg, residue is not more than 0.01 mg/kg;
For sausage, fish meat paste, grape juice, bean product, the max dosage is 3.0g/kg;

It can work with sodium bicarbonate in the ration of 2:1 to make cracker, bread and cake, the dosage is 0.13% of weight of flour .It is made of starch, is not-toxic and harmless to Human.

GDL is commonly found in honey, fruit juices, personal lubricants, wine[citation needed], and has been marketed for use in feta cheese. GDL is neutral, but hydrolyses in water to gluconic acid which is acidic, adding a tangy taste to foods, though it has roughly a third of the sourness of citric acid. 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.

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. The rate of hydrolysis of GDL is increased by heat and high pH.

The yeast Saccharomyces bulderi can be used to ferment gluconolactone to ethanol and carbon dioxide. The pH value greatly affects culture growth. Gluconolactone at 1 or 2% in a mineral media solution causes the pH to drop below 3. (via wikipedia)
