Origin
E 331 is obtained from citric acid by neutralizing soda lye with citric acid.
Usage
No authorization restrictions exist for the use as a food additive for E 331. Similarly, there are no maximum quantity restrictions for sodium citrate regarding its addition to foods. The acidity regulator E 331 is primarily used in the following foods: jam, preserves, baked goods, energy drinks, condensed milk, fruit and vegetable canned products, meat products, cut fruits and vegetables, sweets, desserts, meat products, effervescent powders, fats, and baking powder.
Risks
Sodium citrate is considered completely harmless. However, mold allergy sufferers should be cautious because the citric acid used for the production of E 331 is mostly produced industrially from mold cultures.
