Potassium phosphates
What is Potassium phosphates?
Potassium phosphates are salts that combine potassium with phosphate, commonly used in the food industry. They are produced synthetically from the chemical reaction between potassium hydroxide and phosphoric acid.
In food and beverages, potassium phosphates serve various purposes, such as buffering agents, emulsifiers, and nutrients that maintain pH balance. They can also act as leavening agents in baking. While generally recognized as safe by major food safety authorities, high intake of phosphate additives has raised concerns about potential impacts on bone health and kidney function, but these are often more relevant to individuals with specific health conditions.
When you see potassium phosphates on a label, it's typically as a multi-functional additive used to stabilize the product or enhance its nutritional profile, particularly for its potassium content.
Commonly found in: baking products, processed meats, beverages, dairy substitutes, processed cheese, supplements
