Sodium gluconate is the sodium salt of gluconic acid, produced by fermentation of glucose. It is a white to tan, granular to fine, crystalline powder, very soluble in water. Non-corrosive, non-toxic and readily biodegradable (98 % after 2 days), sodium gluconate is more and more appreciated as a chelating agent.
The outstanding property of sodium gluconate is its excellent chelating power, especially in alkaline and concentrated alkaline solutions. It forms stable chelates with calcium, iron, copper, aluminium and other heavy metals, and in this respect, it surpasses all other chelating agents, such as EDTA, NTA, and related compounds.
Food-grade sodium gluconate is widely used in the food processing industry, such as effectively replacing salt to make reduced-salt or salt-free bread. It can also replace salt in food processing to improve characteristics, adjust fermentation, provide food preservation, and dehydration effects.
