Sodium citrate is used as a flavoring agent
and stabilizer in the food and beverage industry; in the pharmaceutical
industry it is used as a blood clotting agent, expectorant and diuretic
medicines; in the detergent industry, it can alternative to sodium
tripolyphosphate as a nontoxic detergent additive; it is also used in brewing,
injection, photography, pharmaceutical and electroplating, etc.
It contains a lot of citric acid in the
lemon juice, citric acid and calcium ions combine into soluble complexes to
mitigate the effect of calcium ions promote blood clotting, prevention and
treatment of hypertension and myocardial infarction. So it has effect of
anticoagulant. When taking fresh blood in the clinical, add some sterile sodium
citrate or sodium oxalate can prevent blood clotting, therefore, sodium citrate
and sodium oxalate is known as anticoagulants.
Sodium citrate used for soft drinks can
ease the recipe to improve taste. Brewing of acceding to this product can
promote the glycation, the amount is about 0.3%. In the manufacturing of ice
cream and ice cream, sodium citrate used as an emulsifier and stabilizer, its
dosage is 0.2%~0.3%. This product can also be used as the agent prevents
rancidity of dairy products, or thickening agent in processed cheese, meats and
fish, as well as food sweet correction.
Sodium citrate has many of these excellent
properties, making it a very wide range of uses. Sodium citrate is nontoxic, pH
adjusting performance and good stability, as a result, it can be used in the
food industry. The demand is great when sodium citrate used as a food additive.
It primarily as a flavoring agent, buffering agent, emulsifying agent, bulking
agent, stabilizers, preservatives and so on. What's more, compatibility of

flavoring agent in jams, jellies, fruit juices, beverages, cold drinks, etc.
Liquid detergents containing sodium citrate
has an excellent washing performance, such as sodium citrate-containing
cleaning agent is non-corrosive for certain metal appliances, thus it can specifically for cleaning
expensive precision instruments, and metal surfaces look like new after cleaning
by detergent containing citric acid sodium.
Sodium citrate has good complexing
properties, so is widely used in the plating industry; sodium citrate can be
used as retarder admixture in concrete in the construction industry, as it can
promote tensile, compressive strength and frost resistance of cement products;
in terms of environmental protection, sodium citrate can be used for removal of
sulphide in industrial gas. In addition, sodium citrate in brewing and the
photographic industry also has new uses, thereby it further broaden the field
of application of sodium citrate. If you have interest to okchem, please click here, thanks!
