Product Description

GLUCONO-DELTA LACTONE

Product Description

Glucono-Delta-Lactone (GDL) is an exceptionally versatile food additive, recognized for its multifunctionality. With a chemical formula of C6H10O6 and a molecular weight of 178.14, its CAS number is 90-80-2. This remarkable compound presents as a white crystal or crystalline powder, boasting an almost odorless profile. Its initial taste is delicately sweet, transitioning to a subtle sourness. Highly soluble in water yet insoluble in ether, GDL undergoes a slow hydrolysis in aqueous solution, resulting in a dynamic equilibrium of gluconic acid and its δlactone, which is known to decompose at approximately 153°C.

Application field:

1. Food industry
Protein coagulant: Distinguished for its extensive use in soybean products like tofu and douhua, GDL significantly enhances water retention, producing a tender texture in the final product and nearly doubling the production rate.

Sour and leavening agent: When combined in a 2:1 ratio with sodium bicarbonate, GDL forms baking powder, ideal for bread, biscuits, and other baked delights. Its usage is about 0.13% of the flour weight.

Preservation preservative: Perfect for fish and shrimp preservation with a maximum usage of 0.1g/kg and a residual amount under 0.01mg/kg, GDL also prevents milk stone formation in dairy products.

2. Daily chemicals and industry

Cosmetics and toothpaste: GDL serves as an effective pH regulator and chelator, aiding in the removal of tartar and enhancing overall product performance.

Electroplating and cleaning: This compound is integral in metal polishing and cleaning agent formulations, significantly improving the surface treatment outcomes.

3. Medicine and Research
Standards and reagents: Utilized in the detection of gluconolactone content within meat products, following the GB/T 9695.17-2008 standard, and valuable for isotope labeling analysis.
