In a nutshell ​

Potassium phosphates are multifunctional phosphates for emulsifying and acidity; safe within limits but watch phosphorus intake.

Consumer Advice ​

Potassium phosphates are the potassium salts of phosphoric acid, used as emulsifying salts, buffers and moisture retainers in processed cheese, meat products and drinks, similar to sodium phosphates. They are safe at authorised levels. People with kidney problems or who must limit phosphorus or potassium should be mindful, as excess phosphate is linked to kidney and bone health concerns.
