Sodium Gluconate (C6H11NaO7)

What is Sodium Gluconate?

Sodium gluconate is the sodium salt of gluconic acid, which is produced by the fermentation of glucose. This substance, with the chemical formula C6H11NaO7, is a white, fine-grained compound that dissolves rapidly in water and is non-corrosive and non-toxic.

• It forms strong complexes with metal ions.
• It functions as a pH regulator.
• It is environmentally friendly and biodegradable.

Thanks to these properties, it has a wide range of applications, from food additives to construction chemicals.

How is Sodium Gluconate Produced?

Sodium gluconate production consists of several steps:

1. Fermentation
   • Glucose is fermented using specific microorganisms (Gluconobacter species) to produce gluconic acid.
2. Crystallization
   • Gluconic acid is crystallized for purification.
3. Neutralization
   • Crystallized gluconic acid is reacted with sodium hydroxide (NaOH) to produce sodium gluconate.
4. Purification
   • Pure products are obtained through various filtration and purification processes.
5. Packaging
   • It is packaged in bags in granular form for industrial use.
