What’re the Uses of Sodium gluconate?

Sodium gluconate is different with other gluconates that can be used as a nutrient, this ingredient is mainly used as a chelating agent and cleaner in food and industrial uses.

It is a multi-functional ingredient that can be used in a lot of fields, commonly used for its outstanding chelating property in food and industrial uses. Also used for its PH buffering and taste improvement in food.


Food grade sodium gluconate can be used as:

Sequestering agents work by chelating undesirable metal ion agents. PH buffer in beverages. Improve the taste of beverages by masking off-flavors or reducing the bitterness/aftertaste of artificial sweeteners, soy protein, minerals, or caffeine. A stabilizer in meat products, by increasing the water binding capacity of meat and improving its hardness and sliceability. At the same time, sodium gluconate is a substitute for phosphate.

Pharma & Nutraceutical

It can be used as an excipient as a buffer and pH adjuster in the following products:

Syrups;Suspension;Swallowable/orallydispersibletablets;Hard capsules;Others ;


Sodium gluconate functions as a chelating and skin conditioning in cosmetic and personal care products. And usually we can find it in skin care products like face cream, soap, and toothpaste.

Industrial uses

Chelating agent

With good sequestering power (over EDTA, NTA and some other related compounds) to combine with di- and trivalent metal ions, such as calcium, iron, copper, aluminium to form stable chelates and take them out of water or the solution at an alkaline pH, and with little effect on temperature.

Because of this feature, it is widely used:

Water treatment ;Bottle washing;Corrosion inhibition;Metal surface treatment;Industrial cleaning

Concrete retarder

In addition, it can be used in the construction industry, as a retarding cement enhancing additive.

Is sodium gluconate safe to eat?

Yes,Improve the taste of beverages by masking off-flavors or reducing the bitterness/aftertaste of artificial sweeteners, soy protein, minerals, or caffeine.

Frequently asked questions

How is it made?

Sodium gluconate can be synthesized from the reaction of gluconic acid ( produced by oxidation of D-glucose, derived from starch) and sodium hydroxide.

Is it gluten free?

Yes, it is gluten free as it does not contain wheat, rye, barley, or crossbreeds of these grains, therefore can be used for people with celiac disease.

Gluconic acid vs sodium gluconate?

Gluconic acid is the liquid, not convenient to use in some applications, and where it is combined used with sodium hydroxide, better to use sodium gluconate directly.
