General Information
Tripotassium phosphate (food additive E340(iii)) is a strongly alkaline salt that belongs to the group of potassium phosphates (additive E340).
The chemical formula of additive E340(iii) is K3PO4. It is a white crystalline powder, highly soluble in water, with pronounced alkaline properties.
In the food industry, additive E340(iii) is used less frequently than E340(i) and E340(ii) due to its high alkalinity. It is mainly applied as an acidity regulator and stabilizer in products that require a slightly alkaline environment. E340(iii) is used in certain confectionery products to enhance the effect of anti-caking agents and in processed cheese formulations where pH adjustment above 9 is needed.
Additionally, additive E340(iii) can enhance the action of antioxidants, making it a useful auxiliary component in various technological processes.
