As a buffering agent
DKP has relatively little flavor and is therefore sometimes used as a buffering agent in powdered foods – or medicines.
For example, it’s commonly seen in a lot of food powders to add a safe relatively inert material.
As an anti-coagulation agent
DKP is good at preventing coagulation in liquids which might otherwise separate while in transit, or on the shelf.
One significant application, in this case, is non-dairy liquid creamers, where it maintains the creamy texture of the product across a long shelf life.
As an antioxidant
Dipotassium phosphate is one of numerous preservatives with antioxidant properties and can be found in numerous food products because of that.

What are phosphates?
Phosphates are a group of inorganic chemicals that are obtained through the neutralization of phosphoric acid which results in the substitution of a hydrogen cation and produces a salt.
There are several varieties of phosphate salts, depending on the reaction source, such as potassium hydroxide being used to create a potassium phosphate.
How is Dipotassium Phosphate made?
Dipotassium Phosphate (DKP) has been used in food production for decades and is made by reacting a source of potassium (usually potassium hydroxide) with phosphoric acid.
Food-grade phosphoric acid is made from phosphate rocks, which are mined, refined and purified. Companies that make phosphoric acid in the U.S., Europe and elsewhere follow strict procedures to ensure purity.
The phosphoric acid is reacted with potassium hydroxide and lime water to form a wet mix.
The resulting reaction creates potassium phosphate, which is then dried and crystalized.
Finally the product is sized down to specifications.
Food grade phosphates that are manufactured in the United States comply with the new regulations for food safety as set forth in the Food Safety Modernization Act.
Why are phosphates in my food?
DKP has many uses in food.
Dipotassium phosphate has the ability to act as an emulsifier, protein stabilizer and buffering agent.
In addition Dipotassium phosphate can provide a source of Potassium for many foods that otherwise would not have that.
Some common uses are as follows:
Coffee Creamers – DKP can help stabilize the protein layer around fat droplets present in the milk, which helps prevent syneresis and curdling when added to a hot beverage.
Processed cheese products – DKP help buffer the pH and interact with the milk proteins to promote emulsification.
Nutrient resource – the potassium present can be used as a mineral supplement for pharmaceuticals and a nutrient base during yeast production and other fermentation processes.
Soy protein based beverages – DKP can help stabilize soy proteins and act as a dispersing agent.
How do phosphates benefit my health?
DKP provides potassium which is an important nutrient for the body.
Dipotassium Phosphate (abbreviation DKP), the soluble phosphoric acid salt of dipotassium with the chemical formula K2HPO4, also known as dipotassium hydrogen phosphate or potassium phosphate dibasic.
This ingredient is vegan & gluten-free and can be used as a buffer, sequestrant and nutrient supplement in food with the European food additive number E340(ii).
Like monopotassium phosphate, it is also used to produce fertilizers, while tripotassium phosphate isn’t.
How is Dipotassium Phosphate made?
DKP can be commercially synthesized by the controlled reaction of phosphoric acid with potassium hydroxide or potassium carbonate.
DKP is a buffering agent or an acidity regulator to maintain solution PH to a specific value.
DKP is added to reduce a rapid change in pH when acids or bases are added to the solution.
DKP is used for this purpose to prevent coagulation in non-dairy creamer.
In milk, Dipotassium phosphate increases pH to assure milk protein stability and prevents precipitation.
Drink
DKP is a common source of phosphorus and potassium.
In Coca Cola’s beverages, Dipotassium phosphate is a source of potassium, which provides nutrition and also regulates blood pressure.
Bodybuilding
Phosphorus plays an important role in the production of ATP (adenosine triphosphate), which produces energy for bodybuilders, weightlifters, and athletes during muscular performance. Meanwhile, potassium is an electrolyte which replenishes our body after sweating a lot.
DKP can be used as a nutrient supplement source of both phosphorus and potassium, and also as a buffering agent in energy drinks and a protein stabilizer in protein drinks.
Fertilizer
As a water-soluble phosphorus and potassium-based fertilizer in agricultural applications for growing plants.
Others
DKP can also be used in the culture of microorganisms (e.g. fermentation processes of antibiotics and yeast ) as phosphorus is a component essential for microorganisms growth.

Dipotassium Phosphate Benefits
At a quick glance, the primary benefit of dipotassium phosphate is that it is a convenient source of potassium, which contributes to your normal muscle function.
For weightlifters, bodybuilders and athletes, dipotassium phosphate supplements may be useful for several reasons.
1. May increase energy in workouts
Firstly, Dipotassium phosphate can be used in energy supplements for workouts requiring prolonged periods of work without rest, such as long-distance running, team sports, high-intensity interval training and endurance-style weightlifting sessions.
Dipotassium phosphate does this by supporting the recovery of your muscles, which means a better recovery rate and the ability to get in more lifts.
However, the evidence suggests that the results of potassium phosphate supplementation may vary based on individual response and the specific supplement protocol.
To summarise, dipotassium phosphate improves endurance by increasing your body’s efficiency in transporting oxygen to your muscles, thus helping energy production.
This is particularly effective for high intensity and particularly strenuous exercises such as heavy lifting and sprints.
2. Helps increase your intake of potassium
Potassium is one of the seven essential macro minerals, of which your body requires at least 100 milligrams on a daily basis in order to sufficiently support its key processes.
Whilst Dipotassium phosphate’s possible to hit your requirements from dietary sources such as fruits, vegetables, fish and meat, supplementing potassium can help increase your daily intake.
A healthy intake of potassium decreases your risk of stroke, lowers your blood pressure, protects you against the loss of muscle mass, preserves your bone mineral density, and reduces the risk of kidney stones.
