Product Description

GLUCONO-DELTA LACTONE

Product Description

Introducing the multifaceted marvel: Glucono-Delta-Lactone (GDL). As a versatile food additive, its chemical formula is C6H10O6 with a molecular weight of 178.14 and registered under CAS number 90-80-2. This crystalline powder, which sparkles in white, graces your senses with its mild aroma. Initially offering a sweet sensation, it transitions into a delightful sourness. Highly soluble in water yet defying ether, GDL transforms in aqueous environments by hydrolyzing into a balanced mix of gluconic acid and its δ-lactone. It decomposes robustly at approximately 153 °C, demonstrating its dynamic nature.

Application Field:

1. Food Industry
As a protein coagulant, this ingredient is a game-changer for soybean-based delights like tofu and douhua. It enhances water retention, yielding a tender texture and effectively doubling production efficiency.

When mixed as a sour and leavening agent with sodium bicarbonate (2:1), it forms baking powder, perfect for bread, biscuits, and other baked goods, used at roughly 0.13% of the flour's weight.

In its role as a preservation preservative, GDL preserves the freshness of fish and shrimp (with a maximum usage of 0.1g/kg and residuals under 0.01mg/kg) and prevents milk stone formation in dairy products.

2. Daily Chemicals and Industry

In cosmetics and toothpaste, GDL shines as a pH regulator and chelator, aiding in tartar removal and enhancing product efficacy.

In the realms of electroplating and cleaning, it refines the metal polishing process and boosts the effectiveness of cleaning agent formulations, improving surface treatment outcomes.

3. Medicine and Research
Utilized as standards and reagents, GDL is instrumental in detecting gluconolactone content in meat products (as per GB/T 9695.17-2008) and in isotope labeling analyses.
