Product Description

GLUCONO-DELTA LACTONE

Product Description

Introducing Glucono-Delta-Lactone (GDL), a versatile and multifunctional food additive with the chemical formula C6H10O6, and a molecular weight of 178.14, identified by CAS number 90-80-2. This compound is presented as a white crystal or crystalline powder, almost devoid of any odor. It delights the taste buds with an initial sweet note that gracefully transitions to a sour aftertaste. GDL is highly soluble in water, yet remains insoluble in ether 6813. Upon dissolving in water, it gently hydrolyzes to form a dynamically balanced mixture of gluconic acid and its δ-lactone, decomposing at a temperature of around 153 °C.

Application Field:

1. Food Industry
As a protein coagulant, GDL is extensively utilized in the production of soybean products like tofu and douhua, significantly enhancing water retention, resulting in an exceptionally tender texture and nearly doubling production efficiency.

GDL serves as a sour and leavening agent, perfectly blending with sodium bicarbonate (2:1) to create baking powder ideal for breads, biscuits, and other baked delights, used at approximately 0.13% of the flour weight.

As a preservation preservative, it is employed in the conservation of fish and shrimp (with a maximum usage of 0.1g/kg and a residual amount less than 0.01mg/kg), and aids in preventing the formation of milk stone in dairy products.

2. Daily Chemicals and Industry

In cosmetics and toothpaste, GDL acts as an efficient pH regulator and chelator, assisting in the removal of tartar, thus enhancing product efficacy.

For electroplating and cleaning, GDL is utilized in metal polishing and cleaning agent formulations, significantly improving surface treatment results.

3. Medicine and Research
GDL is employed as a standard and reagent for the detection of gluconolactone content in meat products (as per GB/T 9695.17-2008) and for isotope labeling analysis, providing precise and reliable results.
