Tripotassium Phosphate

Tripotassium Phosphate, Anhydrous (TKP) Granular and Powder, with a formula K3PO4, is in the form of white, free-flowing, powder or granules.

Tripotassium phosphates are highly soluble phosphate salts that can be added to juice as a source of potassium. This product includes properties that make it a strongly alkaline salt, protein modifier, emulsifying agent, and buffer capacity. The high alkalinity of TKP is advantageous when quicker cooking rates are desirable in cooked breakfast cereals. Increased pH also makes the product more creamy or yellow in color giving a richer appearance.

Tripotassium phosphate can be produced by the reaction of ammonium phosphate ((NH4)3PO4) with potassium chloride (KCl)

(NH4)3PO4 + 3KCl → K3PO4 + 3NH4Cl

It is used as a food additive for its properties as a foaming agent, emulsifier, and whipping agent. In combination with fatty acids, this chemical can be used as an antimicrobial agent in poultry processing.

It is also used in food industry. Increased pH makes the product more creamy or yellow in color giving a richer appearance.


Applications of Tripotassium phosphate

Use as a Supplement
Phosphorus in some form is found in many multivitamin and minerals supplements to help meet the recommended dietary allowance of 700 milligrams per day for adults.

Separate tripotassium phosphate supplements are typically only used for treating low phosphate levels, such as those that occur in certain hereditary disorders. These supplements should only be used under a doctor’s supervision. Most adults shouldn’t consume more than the tolerable upper intake level of 4,000 milligrams of phosphorus per day, which includes phosphorus from other supplements and foods. Underlying medical conditions might change your tolerance for phosphorus, so check with your doctor to ensure a safe intake.

Use as a FoodAdditive
Tripotassium phosphate helps stabilize, thicken and regulate the acidity and moisture in foods. It’s often used in large amounts in soft drinks, canned fish, processed meats, sausages, ham and baked goods. Canned and dried vegetables, chewing gum, chocolate products, condensed milk, puddings, breakfast cereals, candies, crackers, alcoholic beverages, pasta, fruit juices, dairy products, salt substitutes and other seasonings, soups and tofu can also contain tripotassium phosphate. Overall, any kind of processed foods, including fast foods, may contain added phosphates such as tripotassium phosphates.

Medical Use
Tripotassium phosphate is sometimes used as a medicine. It can have a diuretic effect and act as a laxative when used in medicinal amounts. However, phosphorus can interact with some medications, including corticosteroids and potassium-sparing diuretics, increasing the risk for adverse effects; only use it when advised to do so by a doctor.

Potential Health Considerations
Phosphate additives in food, such as tripotassium phosphate, are more readily absorbed by the body than phosphates naturally found in foods, increasing the risk that people with kidney problems may unintentionally consume too much phosphorus. Getting too much phosphorus could increase the risk for heart disease and, even in people with normal kidney function, increase the risk of mortality from any cause.
