Natriumsitraatti

Natriumsitraatti, known in English as sodium citrate, is a chemical compound with the formula Na₃C₆H₅O₇. It is the sodium salt of citric acid, a natural organic acid found in citrus fruits. Sodium citrate appears as a colorless, crystalline powder with a mildly salty, tart taste.

This compound is widely used in the food industry as an acidity regulator, preservative, and flavor enhancer. It helps control pH levels in processed foods, such as cheeses, soft drinks, and baked goods. Sodium citrate also functions as an anticoagulant in blood collection and storage, preventing blood clotting by binding calcium ions required for coagulation.

In the medical field, sodium citrate is used in certain treatments, including urinary alkalization and managing metabolic acidosis. It can also be found in medication formulations to stabilize and preserve their integrity.

Chemically, sodium citrate is soluble in water, forming a buffer solution that stabilizes pH. It is produced by neutralizing citric acid with sodium hydroxide or sodium carbonate.

Sodium citrate is generally regarded as safe (GRAS) when used in regulated quantities but should be consumed within recommended limits to avoid potential side effects, such as gastrointestinal discomfort.

Overall, sodium citrate is a versatile compound valued in various industries for its buffering and preservative properties, as well as its role in healthcare applications, all rooted in its natural derivation from citric acid.
