Product Description

GLUCONO-DELTA LACTONE

Product Description

Glucono-Delta-Lactone (GDL) is a versatile and multifunctional food additive with the chemical formula C6H10O6, and a molecular weight of 178.14. It is identified by CAS number 90-80-2. This substance presents as a white crystal or crystalline powder with a subtle, almost odorless profile. Initially sweet to the taste, it transitions to a gentle sourness. GDL is highly soluble in water, though it remains insoluble in ether 6813. Upon being dissolved in water, it gradually hydrolyzes to establish a dynamic equilibrium mixture of gluconic acid and its δ-lactone, with decomposition occurring at approximately 153°C.

Application field:

1. Food industry
Protein coagulant: Extensively utilized in soybean creations like tofu and douhua, this agent significantly enhances water retention, bestowing a tender texture upon the finished products while nearly doubling the production rate.

Sour and leavening agent: When combined with sodium bicarbonate in a 2:1 ratio, it forms baking powder ideal for breads, biscuits, and various baked delicacies, with a recommended usage of about 0.13% of the flour weight.

Preservation preservative: Employed in the preservation of fish and shrimp with a max usage of 0.1g/kg and ensuring residues remain below <0.01mg/kg. It also prevents milk stone formation in dairy products.

2. Daily chemicals and industry

Cosmetics and toothpaste: Serves as an exemplary pH regulator and chelator, playing a critical role in tartar removal.

Electroplating and cleaning: Integral to metal polishing and in the formulation of cleaning agents, enhancing surface treatment outcomes.

3. Medicine and Research
Standards and reagents: Essential for detecting gluconolactone levels in meat products, referring to GB/T 9695.17-2008, and pivotal in isotope labeling analysis.
