Food Grade Glucono Delta Lactone (GDL)

About Glucono Delta Lactone:
Glucono Delta Lactone as a white crystalline powder, odorless, sweet taste after the first acid, turning on the water, micro-content in ethanol. Glucono Delta Lactone protein can form a sol-gel, and a certain degree of corrosion resistance. Glucono Delta Lactone as a good multi-functional food additive, it is mainly used for protein coagulant, acid agents, bulk agents, preservatives, flavoring agents, adhesives, etc. Glucono Delta Lactone is widely used in food, daily use of chemicals, pharmaceuticals, cosmetics, metal cleaning and organic synthesis. E575 non-toxic to humans, harmless, it is a good stabilizer, coagulants, sour agent and chelating agent.


Uses
Glucono delta-lactone (GDL) is a naturally-occurring food additive used 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.

Specification
GDL is commonly found in honey, fruit juices, and wine. Being acidic, it adds 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 the 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.
