E331

Chemical structure of E331

E331 is a food additive that is commonly used in the food industry. It is also known by its chemical name, sodium citrate. E331 is classified as a food acid regulator and is widely used as a flavor enhancer and preservative.

Chemical Properties

Sodium citrate, with the chemical formula C6H5Na3O7, is a white crystalline powder that is highly soluble in water. It is derived from citric acid, which is naturally found in citrus fruits such as lemons and oranges. E331 is produced through a process called neutralization, where citric acid is combined with sodium hydroxide or sodium carbonate.

Uses

E331 has a variety of uses in the food industry due to its versatile properties. It is commonly used as a buffering agent to control the acidity or alkalinity of food products. This helps to maintain the desired pH level and prevent spoilage. Sodium citrate is also used as a chelating agent, which means it can bind to metal ions and prevent them from reacting with other ingredients in the food.

Furthermore, E331 is often added to processed cheese products to improve their texture and prevent them from becoming too oily or greasy. It acts as an emulsifier, helping to blend the fat and water components of the cheese together. This results in a smoother and more stable product.

Safety and Regulations

E331 is considered safe for consumption by regulatory authorities such as the Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). It has been extensively studied and has not been found to have any significant adverse effects on human health when consumed in normal amounts.

However, it is important to note that some individuals may be sensitive or allergic to sodium citrate. In rare cases, it can cause digestive disturbances such as diarrhea or stomach cramps. If you experience any adverse reactions after consuming products containing E331, it is recommended to consult a healthcare professional.
