Trisodium citrate is a salt of citric acid. With complete neutralization, high purity citric acid produces sodium hydroxide or carbonate. Widely used in food, beverage and various industrial applications as a buffer, sequence and emulsion agent.
Sodium is metallically white to silvery white in its original form. The sixth most abundant element is 2.6% of the Earth’s crust. It does not exist in nature as a free element and must be extracted from its compounds.
Trisodium citrate is found as granular and white crystals or as a white crystalline powder with a pleasant and salty taste. It is soluble in water and practically insoluble in ethanol (96%).
It is a non-toxic and neutral salt with low reactivity. If stored at room temperature, it is chemically stable. Trisodium citrate is completely biodegradable and can be disposed of with ordinary waste or wastewater.
Commonly known as safe food (GRAS), citrate salts, including sodium citrate salts, are usually considered safe when used in normal amounts.
Sodium tricitrate is produced by neutralizing citric acid with sodium hydroxide. Citric acid may be produced from fruit or other foods through yeast fermentation and solvent extraction. Most large-scale production is done by fermenting molasses or other sugar reserves with Aspergillus niger. The liquid is separated by filtration and the citric acid is separated by precipitation. Sodium citrate is usually marketed as a white, crystalline substance.
Anhydrous sodium trisitrate is produced from trisodium citrate dihydrate. Water molecules of dihydrate crystals are removed by one process, without removing the original crystal matrix. The resulting crystals have a porous matrix that can be used as carriers of minerals or organics such as perfumes and surfactants. Trisodium citrate has a very good ability to absorb excess water from moisture-sensitive formulations due to its lack of water, thus providing better durability for the final product. Anhydrous sodium triscylate is used in water-sensitive formulations such as instant beverages as well as tablets and powders and detergents. Anhydrous form can offer special benefits in dry products that require long shelf life.
Citrate is used in the food and beverage industries due to its buffering, pH and flavor control properties. Citric acid is the most common acid in the industry. As a food additive, citric acid is used as a flavoring and preservative. Sodium citrate or trisodium citrate is used as an antioxidant in food as well as in enhancing the effects of other antioxidants. Sodium citrate can also be used as an acidity regulator and separator. Potassium citrate acts as a buffering agent to adjust the pH when added to water to form buffer solutions.
This substance may be used as an alkaline agent, buffer, emulsifier.
In food, it helps control the acidity of ice cream, candy, jellies and gelatin desserts.
Often used as an aromatic substance for various beverages such as fruit juices, soft drinks and energy drinks.
Sodium citrate is also often added to highly acidic liquids, specifically for the spherification technique to help neutralize and promote the gel. Gelling does not occur when liquids have a higher acidity than PH5. Reducing the acidity of the liquid can be done by directly adding sodium citrate to the gel solution. A concentration of 0.5 to 2 g per liter of liquid should be dissolved before adding any gel.
The amount of sodium citrate used depends on the desired result. Increasing the amount causes stronger gels, while lower amounts cause more lubrication. Because sodium tricitrate has a salty, sour, and slightly bitter taste, it should be used in appropriate proportions in liquids.
Sodium tricitrate is the most widely used emulsifying salt in processed processed cheese products. And is used as an emulsifier in the production of dairy products such as cheese. Allows the cheese to melt without degreasing. Sodium was used to retain water and fats when cheese was melted.
Also used in soy products and bakery flavors.
Medically, it is used as an alkaline substance.
The combination of citric acid, potassium citrate and sodium citrate is used to prevent gout or kidney stones or metabolic acidosis in people with kidney problems.
Citrate is a weak base and therefore reacts with hydrochloric acid in the stomach to raise the pH. It is further metabolized to bicarbonate, which acts as a systemic alkaline substance and raises the pH of blood and urine.
Sodium citrate is often used to prepare sodium citrate buffer for antigen retrieval in tissue samples. The citrate solution is designed to break protein crosslinks. Therefore, it does not fix antigens in tissue sections with formalin-fixed paraffin and increases the intensity of antibody staining. Citrate has anticoagulant activity and, as a calcium, forms complexes that disrupt the blood’s tendency for blood to clot.
Potassium tricitrate has diuretic properties.
Can also be used as a laboratory reagent.
It is also used in making medicines such as cough syrup
.Used in the pharmaceutical industry to control pH.
Sodium tricitrate is used to relieve pain and vitamin pills.
Often used as a pH regulator and water softener. The use of sodium tricitrate in laundry detergents is common.
This material meets the standards of body care products. It is available in dozens of personal care products such as shampoo, conditioner, sunscreen, facial moisturizer, baby wipes, soap and other similar products.
Widely used in dental cleaning products.
Used as a chemical for water treatment.
In water treatment, it is preferred in some cases due to high charge, and this causes it to destabilize and eliminate suspended matter compared to other aluminum salts such as aluminum sulfate, aluminum chloride, ferric chloride and other coagulants. Ordinary and various forms of poly aluminum are effective. Chloride in which the structure of aluminum leads to a lower net charge than aluminum chloride.
Sodium citrate in the oil industry for flooding or injecting water is where water is injected into the formation of oil or gas to increase the pressure in the formation and thereby stimulate production. Water injection or water flooding is done to increase oil recycling from an oil or gas tank inside and outside the country. Water is injected from the reservoir to support the reservoir pressure (known as the discharge substitute) as well as to move or displace oil, directing it to the production well.
The practice of adding sodium citrate to milk, which is used as a baby food, has been common for many years. This substance is especially useful in the treatment of certain types of “nutrition” in which milk, after entering the stomach, forms large pieces such as hard cheese, which may pass almost unchanged throughout the intestinal tract and cause irritation. Be mechanical, which often leads to serious interference with the natural digestion process. This can be corrected or controlled by adding 1 or 2 grains of sodium citrate per ounce of milk.
Sodium tricitrate has recently been used in the sand oil extraction industry. Adding sodium citrate as a secondary process aid with sodium hydroxide (NaOH) improves bitumen recycling in the ore.
Sodium tricitrate with citric acid is used as a buffer and complexing in plating baths. Buildings and textile industries also benefit from the extraordinary ability of citric acid and its non-toxicity. This material is used in flue gas and oil recycling.
Adhesives, sealants, chemicals, chemical fertilizers, construction, inks, paints, coatings, metal work surfaces, ore extraction and refining, oil drilling, paper, plastics and polymers It has applications.
