Product Description

GLUCONO-DELTA LACTONE

Product Description

Glucono-Delta-Lactone (GDL) is a versatile and multifunctional food additive. Its chemical composition is C6H10O6, with a molecular weight of 178.14 and a CAS number of 90-80-2. This remarkable substance presents itself as a white crystal or crystalline powder, exhibiting almost no odor. Initially sweet to taste, it transforms into a delightful sourness. GDL is highly soluble in water, yet remains insoluble in ether at 6813. In aqueous solutions, it undergoes a slow hydrolysis, forming a dynamically balanced blend of gluconic acid and its δlactone, which gracefully decomposes at approximately 153°C.

Application field:

1. Food industry
Protein Coagulant: Widely embraced in soybean-based delicacies such as tofu and douhua, GDL enhances water retention, imparting a tender texture to the final product, while nearly doubling production efficiency.

Sour and Leavening Agent: When combined with sodium bicarbonate in a 2:1 ratio, it creates an effective baking powder. This blend is perfect for bread, biscuits, and other baked delights, with a recommended usage of approximately 0.13% of the flour weight.

Preservation Preservative: Essential for the preservation of fish and shrimp with a maximum usage of 0.1g/kg and minimal residue (<0.01mg/kg). It also combats the formation of milk stone in dairy products, ensuring freshness and quality.

2. Daily chemicals and industry

Cosmetics and Toothpaste: GDL acts as a proficient pH regulator and chelator, enhancing dental hygiene by aiding in tartar removal.

Electroplating and Cleaning: Integral to metal polishing and cleaning agent formulations, GDL significantly improves surface treatment outcomes.

3. Medicine and Research
Standards and Reagents: Employed for the precise detection of gluconolactone content in meat products, as per GB/T 9695.17-2008, and is instrumental in isotope labeling analysis.
