Product Description

GLUCONO-DELTA LACTONE

Product Description

Glucono-Delta-Lactone (GDL) is a versatile marvel in the realm of food additives. This chemical compound, C6H10O6 with a molecular weight of 178.14 and CAS number 90-80-2, unveils itself as a white crystalline powder. Its sensory journey begins with a gentle sweetness evolving into a mild sourness. GDL dissolves effortlessly in water while resisting ether. Upon encountering water, it slowly transforms into a dynamic equilibrium of gluconic acid and its δ-lactone, decomposing at around 153 °C.

Application field:

1. Food industry
As a protein coagulant, GDL is a superstar in the world of soybean products, enhancing the water retention and tenderness of creations like tofu and douhua, almost doubling production yields.

When used as a sour and leavening agent, GDL combines with sodium bicarbonate (2:1) to forge baking powder. It's a staple in the art of bread and biscuit making, at approximately 0.13% of flour content.

GDL serves as a preservation hero. It is used to preserve the freshness of fish and shrimp (maximum usage 0.1g/kg, with a residual amount less than <0.01mg/kg) and maintains the integrity of dairy products by preventing milk stone formation.

2. Daily chemicals and industry

In cosmetics and toothpaste, GDL plays a crucial role as a pH regulator and chelator, aiding in the removal of tartar, thus enhancing oral and dermal care.

GDL becomes a key player in electroplating and cleaning, enhancing metal polishing and cleaning formulations, ultimately improving surface treatment outcomes.

3. Medicine and Research
GDL is indispensable in standards and reagents. It is used for detecting gluconolactone content in meat products (refer to GB/T 9695.17-2008) and in isotope labeling analysis, making it a research favorite.
