Sodium citrate dihydrate is used as a buffer, pH controlling agent, emulsifier, sequestrant and complexing agent in food industry.
Trisodium citrate dihydrate is a tribasic salt of citric acid. It is produced by complete neutralisation of citric acid with high purity sodium hydroxide or carbonate and subsequent crystallisation. Citric acid is the product of a microbial fermentation using carbohydrate substrates.
Trisodium citrate dihydrate is widely used in foods, beverages and various technical applications mainly as buffering, sequestering or emulsifying agent.
As there are three carboxyl groups in the molecule of citric acid, so there can be three types of sodium citrates (mono, di and trisodium citrate) based on the partial or total neutralization of citric acid.
Among them, trisodium citrate is the most used one in food, while disodium citrate is seldom to see in food.
Sodium citrate is a derivative of citric acid; the name may refer to any of the sodium salts of citric acid but usually to trisodium citrate dihydrate.
Trisodium citrate has the chemical formula of Na3C6H5O7.
It is sometimes referred to simply as “sodium citrate”, though sodium citrate can refer to any of the three sodium salts of citric acid. It possesses a saline, mildly tart flavor, and is a mild alkaline.

Sodium salts of citric acid that are used as buffers and food preservatives. They are used medically as anticoagulants in stored blood, and for urine alkalization in the prevention of KIDNEY STONES.
Sodium citrate, the sodium salts of citric acid with the European food additive number E331.
This ingredient is usually added together with citric acid to enhance flavor or reduce the PH level in food and drinks, also it can act as an emulsifier in cheese making.
It commonly refers to trisodium citrate (E331) when we talk about sodium citrate.
What’re the Uses of Sodium citrate?
Sodium citrate is a multi-functional ingredient that is commonly used in carbonated drinks, powdered drinks, jams, jellies, ice cream, yogurts, processed cheeses, meat, sausage, and ham.
It is mainly used for the following purposes:
Flavoring agent: enhance taste by imparting both a salty and a tart flavor in beverages.
Buffer: commonly used together with citric acid to adjust the PH by reducing the acidity of foods.
Chelating agent: the power of chelating metal ions, e.g. Ca2+, Mg 2+, and Fe2+ in dishwashing and laundry detergents.
Emulsifier: prevent the separation of oil and protein in the cheesemaking process.
Preservative: prevent food spoilage.
Anticoagulant: used as an anticoagulant and prevent blood from clotting by combining calcium ion.
Yogurt
Citric acid adds sour taste to dairy products, but its sour taste is strong, and the sour taste can be eased with the combination of sodium citrate, so these two ingredients are often used together in yogurt to adjust and improve the sour taste.
Cheese
Cheese is an emulsion of dairy fat, protein and water, and it tends to break down at high temperatures.
While it is melting, sodium citrate works as an emulsifier to prevent cheese curdling or the separation of fat and protein by keeping fat and protein together and binding calcium ions in the cheese. The usage in cheese is around 3%, depending on your recipes.
Cheese with sodium citrate can melt evenly and produce a smooth & creamy sauce. This property makes it possible to obtain portable and sliceable cheese (in mold, can take everywhere) in home cooking.

Excellent performance
Sodium citrate is currently the most important citrate. It is produced by two steps: first starch food is fermented to generate citric acid; secondly, citric acid is neutralized by alkali to generate the final products. Sodium citrate has the following excellent performance:
Safe and nontoxic properties; Since the basic raw material for the preparation of sodium citrate mainly comes from the food, it is absolutely safe and reliable without causing harm to human health. The United Nations Food and Agriculture and the World Health Organization has no restriction in its daily intake, which means that this product can be considered as non-toxic food.
It is biodegradable. After subjecting to the dilution of a large amount of water, sodium citrate is partially converted into citrate, which coexists with sodium citrate in the same system. Citrate is easy to subject to biological degradation at water by the action of oxygen, heat, light, bacteria and microbes. Its decomposition pathways are generally going through aconitic acid, itaconic acid, citraconic acid anhydride to be further converted to carbon dioxide and water.
The ability of forming complex with metal ions. Sodium citrate has a good capability of forming complex with some metal ions such as Ca2+, Mg2+; for other ions such as Fe2+, it also has a good complex-forming ability.
Excellent solubility, and the solubility increases with increasing temperature of water.
It has a good capability for pH adjustment and a good buffering property. Sodium citrate is a weak acid-strong alkali salt; When combined with citrate, they can form a pH buffer with strong compatibility; therefore, this is very useful for some cases in which it is not suitable to have large change of pH value. In addition, sodium citrate also has excellent retardation performance and stability.

Applications
Foods
Sodium citrate is chiefly used as a food additive, usually for flavor or as a preservative. Its E number is E331. Sodium citrate is employed as a flavoring agent in certain varieties of club soda. It is common as an ingredient in bratwurst, and is also used in commercial ready-to-drink beverages and drink mixes, contributing a tart flavor. It is found in gelatin mix, ice cream, yogurt, jams, sweets, milk powder, processed cheeses, carbonated beverages, and wine[citation needed], amongst others.
Sodium citrate can be used as an emulsifying stabilizer when making cheese. It allows the cheese to melt without becoming greasy by stopping the fats from separating.
Buffering
Speciation diagram for a 10-millimolar solution of citric acid. The violet curve corresponds to the trisodium citrate.
As a conjugate base of a weak acid, citrate can perform as a buffering agent or acidity regulator, resisting changes in pH. It is used to control acidity in some substances, such as gelatin desserts. It can be found in the milk minicontainers used with coffee machines. The compound is the product of antacids, such as Alka-Seltzer, when they are dissolved in water.[citation needed] The pH of a solution of 5 g/100 ml water at 25 °C is 7.5 – 9.0. It is added to many commercially packaged dairy products to control the PH impact of the gastrointestinal system of humans, mainly in processed products such as cheese and yogurt.
Medicine
In 1914, the Belgian doctor Albert Hustin and the Argentine physician and researcher Luis Agote successfully used sodium citrate as an anticoagulant in blood transfusions, with Richard Lewisohn determining its correct concentration in 1915. It continues to be used today in blood-collection tubes and for the preservation of blood in blood banks. The citrate ion chelates calcium ions in the blood by forming calcium citrate complexes, disrupting the blood clotting mechanism. Recently, trisodium citrate has also been used as a locking agent in vascath and haemodialysis lines instead of heparin due to its lower risk of systemic anticoagulation
Sodium citrate is used to relieve discomfort in urinary-tract infections, such as cystitis, to reduce the acidosis seen in distal renal tubular acidosis, and can also be used as an osmotic laxative. It is a major component of the WHO oral rehydration solution.
It is used as an antacid, especially prior to anaesthesia, for caesarian section procedures to reduce the risks associated with the aspiration of gastric contents.
Boiler descaling
Sodium citrate is a particularly effective agent for removal of carbonate scale from boilers without removing them from operation and for cleaning automobile radiators.

Waters
Within this market, citric acid or its salts perform several functions. The dominant application is for flavor enhancement.
Many of the lemon, lime or citrus soft drinks available today use citric acid as a way of enhancing the tangy, zesty flavor consumers associate with these tropical fruit flavors. Additionally, citric acid can help provide consistency in acidity and flavor of fruit juices or fruit cordials.
If used together with sodium citrate, it is possible for citric acid to help maintain the flavor of other types of soft drinks without adding to the tanginess.
Sodium citrate can also provide a cool saline taste.
Healthcare
Effervescent tablets and preparations: The reaction of citric acid and bicarbonate liberates carbon dioxide, which aids the dissolution of active ingredients and improves palatability. Effervescent systems are widely used in denture-cleaning products, as well as pain relief and vitamin tablets.
Pharmaceutically active substances — many are supplied as their citrate salt.
pH control: Citric acid, with sodium or potassium citrate, is an efficient buffering system used in a variety of pharmaceutical and cosmetic applications for improving stability and (where appropriate) enhancing the activity of preservatives.
Flavor: The sharp, acid taste of citric acid (which is often used to enhance fruit flavors) can help mask the unpleasant, medicinal taste of pharmaceuticals.
Antioxidant: The citrate ion is a powerful chelating agent for trace metal ions.
Blood anticoagulant: The citrate ion will chelate calcium, thereby reducing the tendency for blood to clot.
Diuretic – potassium citrate has diuretic properties.

Cleaners & Detergents
The major components of cleaning products are surfactants and builders. Other ingredients are added to provide a variety of functions, e.g., increasing cleaning performance for specific soils/surfaces, ensuring product stability, and supplying a unique identity to a product.
Complex phosphates and sodium citrate are common sequestering builders. Builders enhance or maintain the cleaning efficiency of the surfactant. The primary function of builders is to reduce water hardness. This is done either by sequestration or chelation (holding hardness minerals in solution); by precipitation (forming an insoluble substance); or by ion exchange (trading electrically charged particles). Builders can also supply and maintain alkalinity, which assists cleaning, especially of acid soils; help keep removed soil from redepositing during washing, and emulsify oily and greasy soils.
Dish Washing Industrial Cleaners
Laundry Care Surface Care
Industrial
Citric acid is employed as an industrial cleaner to clear steam blocks and hot water systems of calcium and rust layers. As a chemical polish, citric acid is used to treat aluminum, copper and other metal surfaces. Citric acid and citrates are used as buffering and complexing agents in electro-plating baths. The building and textile industries also take advantage of citric acid’s outstanding chelating ability as well as its non-toxicity. Examples include set retarding of gypsum plasters and textile finishing. Further industrial applications of citric acid and citrates range from desulphurisation of flue gas and oil recovery to the decontamination of radioactive nuclear reactor materials.

Sodium Citrate, Dihydrate, a conjugate base of a weak acid, can perform as a biological buffering agent because it resists changes in pH.
Citric acid is one of a series of compounds responsible for the physiological oxidation of fats, carbohydrates and proteins to carbon dioxide and water.
Sodium Citrate, Dihydrate is often used to prepare sodium citrate buffer for antigen retrieval of tissue samples.
The citrate solution is designed to break protein cross-links; thus, unmasking antigens and epitopes in formalin-fixed and paraffin embedded tissue sections, resulting in enhancing staining intensity of antibodies.
Citrate has anticoagulant activity and as a calcium chelator, it forms complexes that disrupt the tendency of blood to clot.

Application Notes
Citric Acid, Trisodium Salt, Dihydrate is used as a substrate for citrate lyase, a buffer component; an anticoagulant. For anticoagulation use it is typically used at a concentration of approximately 0.129 M (i.e. for 4.5 mL blood use 16.0 mg sodium citrate and 2.1 mg citric acid).
Trisodium citrate dihydrate is a tribasic salt of citric acid.
Trisodium citrate dihydrate is produced by complete neutralization of citric acid with high purity sodium source and subsequent crystallization.
Trisodium citrate dihydrate is used in toothpastes & dental creams, effervescent denture cleansers, mouth rinses and oral hygiene products.
Sodium citrate is the sodium salt of citric acid. It is white, crystalline powder or white, granular crystals, slightly deliquescent in moist air, freely soluble in water, practically insoluble in alcohol. Like citric acid, it has a sour taste. From the medical point of view, it is used as alkalinizing agent. It works by neutralizing excess acid in the blood and urine. It has been indicated for the treatment of metabolic acidosis.
Mechanism of action
Citrate chelates free calcium ions preventing them from forming a complex with tissue factor and coagulation factor VIIa to promote the activation of coagulation factor X 1 2. This inhibits the extrinsic initiation of the coagulation cascade. Citrate may also exert an anticoagulant effect via a so far unknown mechanism as restoration of calcium concentration does not fully reverse the effect of citrate 1. Citrate is a weak base and so reacts with hydrochloric acid in the stomach to raise the pH. It it further metabolized to bicarbonate which then acts as a systemic alkalizing agent, raising the pH of the blood and urine 8. It also acts as a diuretic and increases the urinary excretion of calcium.
Food & Beverage
Sodium citrate dihydrate is the most widely used emulsifying salt in sliced processed cheese products. It is commonly used as a buffering agent in combination with citric acid to provide precise pH control required in many food and beverage applications.
Trisodium citrate is often referred to as sodium citrate, though sodium citrate can refer to any of the three sodium salts of citric acid. Sodium citrate has a saline, mildly tart flavor. It is mildly basic and can be used along with citric acid to make biologically compatible buffers.
Sodium citrate is primarily used as a food additive, usually for flavor or as a preservative. In certain varieties of club soda, sodium citrate is employed as a flavoring agent. Sodium citrate is a common ingredient in Bratwurst, and is also used to contribute a tart flavor in commercial, ready-to- drink beverages and drink mixes. It is found in gelatin mix, ice-cream, jams, sweets, milk powder, processed cheeses, carbonated beverages, and wine.
Sodium Citrate is also used as an emulsifier for oils in the cheesemaking process. Sodium citrate allows cheese to melt without becoming greasy. Historically, sodium phosphate was used to keep water and fat droplets mixed when cheese is melted.

Within this market, citric acid or its salts perform several functions. The dominant application is for flavor enhancement. Many of the lemon, lime or citrus soft drinks available today use citric acid as a way of enhancing the tangy, zesty flavor consumers associate with these tropical fruit flavors. Additionally, citric acid can help provide consistency in acidity and flavor of fruit juices or fruit cordials.
If used together with sodium citrate, it is possible for citric acid to help maintain the flavor of other types of soft drinks without adding to the tanginess. Sodium citrate can also provide a cool saline taste.
Healthcare
Effervescent tablets and preparations: The reaction of citric acid and bicarbonate liberates carbon dioxide, which aids the dissolution of active ingredients and improves palatability. Effervescent systems are widely used in denture-cleaning products, as well as pain relief and vitamin tablets.
Pharmaceutically active substances — many are supplied as their citrate salt.
pH control: Citric acid, with sodium or potassium citrate, is an efficient buffering system used in a variety of pharmaceutical and cosmetic applications for improving stability and (where appropriate) enhancing the activity of preservatives.
Flavor: The sharp, acid taste of citric acid (which is often used to enhance fruit flavors) can help mask the unpleasant, medicinal taste of pharmaceuticals.
Antioxidant: The citrate ion is a powerful chelating agent for trace metal ions.
Blood anticoagulant: The citrate ion will chelate calcium, thereby reducing the tendency for blood to clot.
Diuretic – potassium citrate has diuretic properties.

Cleaners & Detergents
The major components of cleaning products are surfactants and builders. Other ingredients are added to provide a variety of functions, e.g., increasing cleaning performance for specific soils/surfaces, ensuring product stability, and supplying a unique identity to a product.
Complex phosphates and sodium citrate are common sequestering builders. Builders enhance or maintain the cleaning efficiency of the surfactant.
The primary function of builders is to reduce water hardness. This is done either by sequestration or chelation (holding hardness minerals in solution); by precipitation (forming an insoluble substance); or by ion exchange (trading electrically charged particles). Builders can also supply and maintain alkalinity, which assists cleaning, especially of acid soils; help keep removed soil from redepositing during washing, and emulsify oily and greasy soils.
Dish Washing Industrial Cleaners
Laundry Care Surface Care
Industrial
Citric acid is employed as an industrial cleaner to clear steam blocks and hot water systems of calcium and rust layers.
As a chemical polish, citric acid is used to treat aluminum, copper and other metal surfaces.

Sodium Citrate is the sodium salt of citrate with alkalinizing activity. Upon absorption, sodium citrate dissociates into sodium cations and citrate anions; organic citrate ions are metabolized to bicarbonate ions, resulting in an increase in the plasma bicarbonate concentration, the buffering of excess hydrogen ion, the raising of blood pH, and potentially the reversal of acidosis.
In addition, increases in free sodium load due to sodium citrate administration may increase intravascular blood volume, facilitating the excretion of bicarbonate compounds and an anti-urolithic effect.
Sodium citrate is the trisodium salt of citric acid. It has a role as a flavouring agent and an anticoagulant.

Abstract
An efficient process to produce a technical-grade trisodium citrate suitable for detergent use has been demonstrated.
Ammonium citrate is produced as an intermediate by a continuous fermentation approach usingCandiada lipolytica yeast and C10–C20 linear paraffin.
After removing yeast cells and residual oil by centrifuge, ammonia is distilled off with addition of sodium hydroxide.
Trisodium citrate is recovered by methanol precipitation.
Impurities, e.g., isocitrate, coloring materials and odorous substances dissolve in methanol and are removed.
The methanol is recovered and recycled.
A simple approach to convert the trisodium citrate solution directly to a solid for possible use in detergents failed because of the objectionable color, odor and high hygroscopicity.
Trisodium citrate dihydrate is a tribasic salt of citric acid.
It is produced by complete neutralisation of citric acid with high purity sodium hydroxide or carbonate and subsequent crystallisation.
Citric acid is the product of a microbial fermentation using carbohydrate substrates.
Trisodium citrate dihydrate is widely used as an excellent pH regulator and odourless buffering agent for bath and shower gels, creams, styling or decorative products.
