Origin
E 508 can be obtained from salt mined in salt mines for industrial use. Since potassium chloride is poorly soluble, it must be extracted from the salt through a chemical process. This usually occurs by crystallization of the substance or E 508 is extracted from salt through heat treatment. After this process, E 508 appears as colorless, salty-tasting crystals.
Usage
In its role as a flavor enhancer, food additive E 508 is often used in ready meals, spices, and calorie-reduced dishes. Generally, E 508 can be used without maximum quantity restrictions in all food products.
Risks
