Food grade Potassium Phosphate Monobasic CAS 7778-77-0

What is Potassium Phosphate Monobasic?

Potassium Phosphate Monobasic , also known as potassium dihydrogen phosphate , is an inorganic salt composed of potassium ions and dihydrogen phosphate ions. It belongs to the acid phosphate family of potassium phosphates.

Its chemical formula is usually:

KH2PO4

in:

· K + represents potassium ions;

· H2PO4−H 2 PO 4 − represents the dihydrogen phosphate ion.

In water, it can dissociate into:

KH2PO4→K++H2PO4− KH 2 PO 4 → K + +H 2 PO 4−

Judging from the English name:

· Potassium stands for potassium.

· Phosphate means phosphate;

· Monobasic indicates a single base, corresponding to dihydrogen phosphate;

· Monopotassium Phosphate refers to monopotassium phosphate.

Food-grade Potassium Phosphate Monobasic is typically a white crystalline, white powder, or granular solid . It is readily soluble in water, and its aqueous solution is acidic or weakly acidic. In food systems, it is commonly used to adjust pH, stabilize flavor, improve processing performance, or provide minerals.

Food-grade Potassium Phosphate Monobasic typically has the following characteristics:

· White crystals or powder ;

· Easily soluble in water ;

· The aqueous solution is acidic or weakly acidic ;

It is readily soluble in water, and its aqueous solution is acidic or weakly acidic. It provides potassium and phosphorus and has acidity regulating and pH buffering functions.

In our daily lives, we may come into contact with Potassium Phosphate Monobasic through the following food-related scenarios:

· Sports drinks and electrolyte drinks;

· Dairy products and plant-based beverages;

· Baked goods and premixed powders;

· Condiments, sauces, and processed foods;

· Nutritional supplements and special dietary foods;

· Fermented foods and food processing.

Food-grade Potassium Phosphate Monobasic is mainly used for:

· Acidity regulator;

· pH buffer;

· Potassium and phosphorus sources;

· Dairy products and plant-based protein beverages are stable;

· Support for baking and leavening systems;
