Potassium Phosphate Dibasic

Potassium phosphate dibasic is a potassium salt of phosphoric acid. It is a white, odourless powder that is soluble in water. It can be produced by neutralising phosphoric acid with a potassium source, such as potassium hydroxide.

It is used as a buffering agent and acidity regulator in foods, helping to maintain a stable pH. It can also function as a sequestrant, binding metal ions to prevent unwanted reactions. It is found in a variety of processed foods, including dairy products, baked goods, and beverages.

Potassium phosphate dibasic is an authorised food additive in Great Britain, listed on the Register of Food Additive Authorisations. European food safety authorities (EFSA) have evaluated it as part of broader assessments of phosphate additives. Phosphates are naturally present in many foods and are essential minerals. When consumed in typical amounts as part of a balanced diet, they are not generally considered a health concern for most people. However, individuals with kidney conditions may need to monitor their phosphate intake.
