Origin
E 332 is industrially obtained from citric acid. The end product is a crystalline powder that dissolves well in water.
Usage
No authorization restrictions exist for the use as a food additive for E 332. Similarly, there are no maximum quantity restrictions for potassium citrate regarding its addition to foods. Potassium citrate is mainly used as an acidity regulator during gelling with pectin, such as in jams, jellies, and preserves. The acidity regulator E 332 is primarily used in the following food products: baked goods, energy drinks, condensed milk, fruit and vegetable preserves, meat products, cut fruits and vegetables, sweets, desserts, meat products, effervescent powders, fats, and baking powder.
Risks
Potassium citrate is considered completely harmless. However, mold allergy sufferers should be cautious because the citric acid used for the production of E 332 is usually industrially produced from mold cultures.
