Product Description

GLUCONO-DELTA LACTONE

Product Description

Glucono-Delta-Lactone (GDL) is an exceptional multifunctional food additive. With the chemical formula C6H10O6 and a molecular weight of 178.14, this distinctive compound is registered under CAS number 90-80-2. It is characterized by its elegant white crystal or crystalline powder form, being nearly odorless, and offering a taste journey from initially sweet to delightfully sour. GDL is highly soluble in water, yet remains insoluble in ether 6813. When introduced to an aqueous solution, it gracefully hydrolyzes, creating a dynamically balanced interplay between gluconic acid and its δ-lactone, with decomposition occurring around 153 °C.

Application field:

1. Food industry
Protein coagulant: This versatile agent is widely implemented in soybean products like tofu and douhua. It enhances water retention, lending a tender texture to the finished product while almost doubling production efficiency.

Sour and leavening agent: In synergy with sodium bicarbonate (in a 2:1 ratio), it forms baking powder. Ideal for breads, biscuits, and other baked delights, it is used at approximately 0.13% of the flour weight.

Preservation preservative: Exceptionally effective for preserving fish, shrimp (maximum usage 0.1g/kg, with residual amounts <0.01mg/kg), and safeguarding dairy products against milk stone formation.

2. Daily chemicals and industry

Cosmetics and toothpaste: Serves as a potent pH regulator and chelator, enhancing tartar removal.

Electroplating and cleaning: An integral component in metal polishing and cleaning agent formulations, it significantly enhances surface treatment outcomes.

3. Medicine and Research
Standards and reagents: Instrumental in detecting gluconolactone content in meat products (in accordance with GB/T 9695.17-2008) and utilized in isotope labeling analysis.
