Product Summary
Sodium Citrate is the sodium salt of citric acid, widely used in food, beverage, pharmaceutical, cosmetic, and industrial applications. It serves primarily as an acidulant, buffering agent, and preservative. Sodium Citrate helps regulate the pH of products, stabilize formulations, and extend shelf life. In food and beverages, it aids in controlling acidity and improving taste, while in pharmaceuticals, it is used in intravenous solutions and as a urine alkalinizer. It also stabilizes pH in cosmetic products and enhances their overall performance. Sodium Citrate is a versatile ingredient with a broad range of uses.
Introduction
Sodium Citrate is derived by neutralizing citric acid with sodium hydroxide, resulting in a white crystalline or powdery substance that is highly soluble in water. As a multifunctional additive, Sodium Citrate is widely used in food processing to adjust acidity, emulsify, and preserve. It is also used in the pharmaceutical industry to regulate the pH of intravenous fluids and treat kidney stones. Its excellent solubility and stability make it an ideal ingredient in a variety of formulations.
Structure
The molecular structure of Sodium Citrate consists of a citric acid molecule combined with sodium ions. This structure allows Sodium Citrate to act effectively as a buffering agent, adjusting acidity levels and preventing products from becoming overly acidic. It has excellent solubility in water, making it suitable for liquid formulations.
