Important Facts about Sodium Citrate

Sodium citrate is a food addition that is especially used in cough syrups and for neutralizing acids in urine. It is also used as a curative assist and as a food additive. It can also be used as a laboratory reagent and as a chemical for treating water. This chemical is ordinarily found as trisodium citrate that is used as an emulsifier, astringency regulator, calcium sequestrant, and preservative.  This sodium citric poison has far-reaching use since comparatively it has a simplest chemistry.

Origin of sodium citrate

Basically, there are 3 forms of sodium citrate –

  1. Monosodium citrate
  2. Disodium citrate
  3. Trisodium citrate

Trisodium is a many ordinarily used several for food products. In sequence to get a sodium citric poison we have to mislay a H+ apportionment of a citric poison and reinstate it with Na+ ions. Practically, this chemical has been a really critical bottom representative in chemistry labs. The sodium citric poison requires some-more poison than normal to revoke pH of any resolution due to this bent it creates easier to make adjustments in acidity.

Its functions

Other than being a buffering agent, this chemical also acts as a sequestering representative that means that it can connect with other ions that are benefaction in a solution. Especially with cheese since it consists of calcium ions that are transposed with sodium ions in sequence to change a structure and display it to oil and water-loving ends.

Its sequestering abilities play a critical purpose in molecular gastronomy. There are some agents that forms jelly in a participation of calcium, though these ions make formidable a routine of hydration of hydrocolloids that is compulsory to form a gel. Sequestrants like sodium citric poison can be used to connect these ions and capacitate a hydration routine properly.

Sometimes calcium reacts with hydrocolloids combining a skinny covering which, however, is expected to start naturally in daub water. So it can be used to revoke calcium and equivocate early gelation. It is also utterly used for this routine as they can boost a pH turn somewhat that can assistance in spherification process.


It is fundamentally used as an emulsifier that is used to make dairy products like cheese since fundamentally it can forestall a dairy product from apropos seared for many days in comparison to other solutions. Sodium citric poison is also used as food additives and found as cooking agents in many products like ice-creams, wine, beverages, divert powders, sweets, and jams.


Temperature – It is soluble in H2O during any heat though a volume of solubility changes with temperature.

Texture- It does not have a structure of a own, though it plays a critical purpose in changing structures of several elements like branch a cheese creamy.

Appearance – It is plain as white granules, that is most like salt.

Flavor release- N/A

Freeze/ Thaw stable- N/A


Shearing- N/A


Interaction and tolerance:

pH ToleranceThis chemical has an ability to somewhat change a pH turn of a resolution when combined in it. As a result, it is really critical to make a resolution some-more resistant to change in pH levels.

Synergies with other ingredients- It is critical component used for spherification process. In glass solutions infrequently it is expected to have an boost in calcium that leads to clumping of hydrocolloids. But here, sodium citric poison is used to trap additional calcium permitting a hydrocolloids to hydrate properly.

It is utterly formidable to establish an accurate thoroughness operation for a unsentimental use of this chemical since it depends on a other mixture that are used. It should be used tolerably since it’s both tainted and green that can impact a flavors of your preparation. If not sure, always deliberate specialist!

As an emulsifier, it is suggested to use 4% of a mass of a product. For creation cheese slices, 3.3% of sodium citric poison should be used with 1.5% iota carrageenan and 0.5% kappa carrageenan.

As a sequestrant, 0.7% to 0.4% can be used depending on a glass and thoroughness of hydrocolloids. In spherification, a volume of sodium citric poison depends on a volume of calcium ions benefaction in a liquid.

So, these were some of a critical contribution about sodium citric poison that one should always keep in mind while traffic with it.
