E335 – Sodium Tartrates
AntioxidantsDescription
White crystalline powder or granules
Notes
Sodium tartrate is the sodium salt of tartaric acid, appearing as a white crystalline powder. It's made by neutralizing tartaric acid (which comes from grapes and winemaking) with sodium carbonate or sodium hydroxide. This chemical reaction creates a more stable compound that dissolves easily in water and has less acidic properties than pure tartaric acid. This additive functions as an acidity regulator, helping to control and stabilize the pH levels in foods, and as a sequestrant, which means it binds to metal ions that could cause foods to spoil or change color. You'll find sodium tartrate in processed cheeses, jams, jellies, baked goods, and some beverages where it helps maintain consistent texture and prevents unwanted chemical reactions. Sodium tartrate is suitable for vegetarian and vegan diets and doesn't present allergen concerns for most people. However, individuals on sodium-restricted diets should be aware that it does contribute to overall sodium intake, though typically in very small amounts. Like other tartrate compounds, it's generally recognized as safe by food safety authorities worldwide.
