Product Name:Delta-Gluconolactone
English Name:Delta-Gluconolactone
CAS No.:90-80-2
Aliases:D-Glucono-1,5-lactone, Gluconic acid delta-lactone, GDL
Molecular Formula:C6H10O6
Physical Properties:White crystalline powder, odorless or with a slight odor. Melting point: 117.8°C. Relative density: 1.760. Easily soluble in water, hydrolyzing slowly; solubility in water is 59 g/100 ml. Slightly soluble in ethanol, with a solubility of 1 g/100 ml; insoluble in ether. The pH of a freshly prepared 1% solution is 2.5. In aqueous solution, it hydrolyzes to form an equilibrium mixture of gluconic acid and its lactone.
Uses:Used as a coagulant for tofu, a flavoring agent, a pH-lowering agent, and a leavening agent raw material. Widely used in the production of soy products in the food industry, and also as an acid regulator and preservative.
