50g Food grade Sodium Gluconate   E576  - Sequestrant , chelating agent - Sodium gluconate is the sodium salt of gluconic acid, produced by fermentation of glucose. It is a white , 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 chelating agent. Sodium gluconate  has a non-irritating, non-bitter , non sour ,  sligthly  salty  taste. The outstanding property of sodium gluconate is its excellent chelating power, It forms stable chelates with calcium, iron, copper, aluminium and other heavy metals,  and  surpasses all other chelating agents, such as EDTA, NTA and related compounds. Aqueous solutions of sodium gluconate are resistant to oxidation and reduction, even at high temperatures. And last but not least, it has the property to inhibit bitterness in foodstuffs.
