Tripotassium Phosphate

Tripotassium Phosphate, Anhydrous (TKP) is a solid white powder, with K₃PO₄. Tripotassium phosphate is an extremely miscible salt that is used as an additive and a source of potassium in juice production. This chemical is grouped as alkaline products and it can be used as, 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.

Chemical and Physical properties 

In the table below some of the chemical and physical properties of this product are mentioned. all data that is mentioned in this table is gathered from the Wikipedia website:

Tripotassium Phosphate synthesis process

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

(NH4)₃PO₄ + 3KCl → K₃PO₄ + 3NH₄Cl [1]

this material is applied as a food additive because of its special characteristics 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 the food industry. Increased pH makes the product more creamy or yellow in color giving a richer appearance. Shanghai Chemex is one of the most reputable manufacturers of this chemical in the world.

Applications of Tripotassium phosphate

Use as a Supplement
Phosphorus in some of its shapes is found in many multivitamin and mineral 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 Food Additive
Tripotassium Phosphate like trisodium citrate 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 
it 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.
