Sodium citrate (also known as citric acid sodium or tricarboxylic acid sodium) is the sodium salt of citric acid. It is a colorless crystal or white crystalline powder, odorless, with a cool, salty and spicy taste. It is soluble in water and the aqueous solution has a slightly alkaline nature (with a pH of approximately 8). It is recognized as a safe food additive (GB 2760, with functions as an acid regulator and stabilizer), possessing multiple characteristics such as being safe and non-toxic, biodegradable, excellent metal ion complexing ability (especially for calcium and magnesium ions), and good pH regulation and buffering performance. Therefore, it is widely used in food and beverage, medicine, personal care and cleaning products, and industrial manufacturing.
Sodium Citrate Application
I. Food and Beverage Industry
Acidity regulators and flavor enhancers: Sodium citrate is the most widely used citrate salt in the food industry. It is commonly used in products such as juices, beverages, jams, jellies, and cold drinks, providing a refreshing and salty taste and mitigating the sourness of citric acid, thereby making the texture more gentle and harmonious. According to GB 2760, it can be used in various foods in an appropriate amount as needed (except for the food categories listed in Table A.2).
Emulsifiers and stabilizers: Used as emulsifiers and stabilizers in the production of ice cream and ice lollies, with an amount of approximately 0.2% to 0.3%, they help improve texture and prevent fat separation; used as thickening agents in the processing of cheese and fish products, to improve the texture of the products.
Buffering and Chelation: When combined with citric acid, it can form a strong pH buffering system, which is used to maintain the stability of food's acidity and alkalinity; at the same time, by chelating calcium, magnesium and other metal ions, it can prevent the spoilage of dairy products and the browning of fruits and vegetables, playing a role in color protection and preservation.
Brewing enhancer: Added during the brewing process, it can promote the saccharification process. The dosage is approximately 0.3%.
II. Medicine and Clinical Practice
Extracorporeal anticoagulant: This is the most common application of sodium citrate in medicine. The citrate ion in it can combine with calcium ions in the blood to form a soluble complex, reducing the blood calcium concentration and thereby blocking the coagulation process. It is used for preserving and processing blood products during blood transfusions. By adding 10 ml of sodium citrate injection to 100 ml of blood, effective anticoagulation can be achieved.
Expectorant, diuretic and auxiliary treatment: Used as an expectorant to help dilute and expel respiratory tract secretions; also has diuretic and diaphoretic effects, used in related drug formulations.
Pharmaceutical excipients and buffers: Used as preservatives and buffers in syrup preparations and injections to maintain the stability of the medicinal liquid.
III. Personal Care Products and Cosmetics
Detergent additives (phosphorus-free alternatives): Sodium citrate can replace the trisodium phosphate found in traditional detergents. As a non-toxic and biodegradable additive, it enhances the cleaning effect by chelating hardness ions such as calcium and magnesium. It is widely used in phosphorus-free laundry powders and liquid detergents. The special cleaning agent containing sodium citrate can also be used to clean vegetables and fruits to remove pesticide residues.
pH regulation and efficacy ingredients in cosmetics: Used in products such as lotions, creams, shampoos, etc. to regulate the acid-base balance and stabilize the formula; also as α-hydroxy acid components, they can promote the renewal of the stratum corneum and are used in skin-whitening and anti-aging skincare products.
IV. Industrial Manufacturing and Chemicals
Electroplating industry: Sodium citrate has excellent metal complexing ability. It is used as a buffer and complexing agent in environmentally friendly electroplating processes such as nickel plating with citric acid salts, and the resulting coating has excellent performance and low corrosion.
Building materials industry: It is used as a retarder for concrete, delaying the setting time of cement to facilitate construction. It can also enhance the frost resistance, compressive strength and tensile strength of cement products.
Environmental-friendly desulfurization and precise cleaning: Using sodium citrate solution to absorb sulfur dioxide in industrial exhaust gases, the absorption rate can reach 99%; at the same time, a non-corrosive cleaning agent specifically for precision instruments can be prepared.
Chemical reagents: Used as chromatographic analysis reagents, raw materials for preparing bacterial culture media, and indicators for complexometric titration, etc.
