Glucono-Delta-Lactone Suppliers, Glucono-Delta-Lactone Manufacturers.
Introduction.:
Glucono delta-lactone (GDL) E575 is a naturally-occurring food additive,It is a lactone (cyclic ester) of D-gluconic acid, and produced by the oxidation of gluconic acid by a number of various methods. In addition to coagulation, GDL is used as an acidulant, leavening agent, and sequestrant,sequestrant, an acidifier, or a curing, pickling, or leavening agent.
Product Identification.:
Product name:Glucono-Delta-Lactone
Synonyms: GDL, 1,5-Gluconolactone; D-Glucono-1,5-lactone; D-Aldonolactone;
D-Glucono-delta-lactone; Gluconic acid lactone; Gluconic lactone
Molecular Formula: C6H10O6
Molecular Weight: 18.14
Molecular structure: →
CASE NO: 90-80-2
EINECS: 202-016-5
Physical & Chemical Properties.:
GDL is a white odorless crystalline powder.
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
Freely soluble in water, sparingly soluble in ethanol.
It is unstable if not sealed well, will be oxidized into colored ones and absorbing moistures in case in air for long time.
Application.:
Potassium sorbate is used to inhibit molds and yeasts in many foods, such as cheese, wine, yogurt, dried meats, apple cider and baked goods.
Potassium sorbate has been used extensively in drink, vegetables in soy, tobacco, drugs, cosmetics, agriculturals products, forage and other domain.
GDL may also be useful in controlling termites by weakening their immune system
