Glucono delta-lactone (GDL) is a naturallyoccurring food additive with the E number E575used as a sequestrant, an acidifier, or a curing, pickling, or leavening agent. It is a lactone (cyclic ester) of D-gluconic acid. Pure GDL is a white odorless crystalline powder.

Glucono delta-lactone (GDL) is commonly found in honey, fruit juices, personal lubricants, and wine[citation needed]. 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 glucose; 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

【Standars of GDL】FCCIV, USP24, E575, GB7657-2005

GDL Properties:

1. Concreting for bean curd

2. Intermedium of medicine

3. Preservative and keep fresh for food

4. Gelatification for milk

5. Improving the quality of food

【Applications of GDL】

1. Tofu coagulant

Tofu produced by GDL is white and tender, no bitter taste, no protein loss. 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 .

2. Gelling agent for dairy products

Mainly used in the production of yogurt or cheese.

3. Quality improver

GDL can be used in pork luncheon meat and canned pork, to improve the effect of colorant.

4. acidifying agent

GDL can be used in fruit syrup or jelly with flavors as vanilla extract, chocolate, banana, etc.

In addition, GDL can be used dairy products as chelating agent, used in beer industry, etc.

5. Dosage and Usage mehtod of GDL
