Origin
Potassium adipate is produced from adipic acid. Adipic acid is originally a substance that occurs in nature, for example, in red beets and sugar beets.
Usage
E 357 is permitted as an additive in the same foods as adipic acid (E 355) or sodium adipate (E 356). In desserts, drink powders, dried dessert powders, coatings for sweets, and fillings for baked goods, the food additive E 357 is often present. E 357 can also be found as a component of salt substitutes. However, salt substitutes and thus also E 357 can only very incompletely replace the taste of cooking salt and are therefore rather unsatisfactory solutions.
Risks
E 357 is a harmless additive and completely safe. Foods containing this substance can be consumed without concern. Overall, it can also be said that adipic acid salts as food additives have relatively little significance, i.e., they are used less frequently compared to other acidity regulators. From the regulatory side, an ADI value (Acceptable Daily Intake) of 5 mg/kg body weight has been set for all adipic acid salts.
