Anhydrous TKP Powder
98%Min Anhydrous 7778-53-2 K3PO4 Tri-Potassium Orthophosphate Anhydrous
Product Description:
Tripotassium phosphate, also known as potassium phosphate, is a white granular powder, easy to absorb moisture, relative density 2.564 (17℃), melting point 1340℃. It is soluble in water and shows alkaline reaction. Insoluble in ethanol. Used as water softener, fertilizer, liquid soap, food additive, etc. It can be prepared by adding potassium hydroxide to dipotassium hydrogen phosphate solution.
Nature and stability
1. It will not decompose if used and stored according to specifications.
2. Avoid contact with oxides, moisture/humidity. It is soluble in water but insoluble in alcohol. The aqueous solution is strongly alkaline. It is highly corrosive. Strong hygroscopicity.

Used to make liquid soap, high-quality paper, refined gasoline,and used as a high effective K,P liquid compound fertilizer.
For food grade, it is mainly used as additive agent,buffering agent, chelating agent, yeast food, emulsifier, potassium fortifier, flavoring agent, meat binder, and softener of boiler water. Also as synergistic agent of anti-oxidation, and useful for the oxidative coupling of thiols to disulfide.
Acidity regulator
Acidity regulator, also known as pH regulator, is a substance used to maintain or change the pH of food. It is mainly used to control acidulants, alkalis and salts with buffering effects required by food. Acidulants have many functional properties to improve food quality, such as changing and maintaining the acidity of foods and improving their flavor; enhancing antioxidant effect and preventing food rancidity; complexing with heavy metal ions to prevent oxidation or browning reaction, stabilize color, and reduce Turbidity, enhanced gelling properties, etc. The acidity regulators approved for use in my country are: citric acid, lactic acid, tartaric acid, malic acid, metatartaric acid, phosphoric acid, acetic acid, hydrochloric acid, adipic acid, fumaric acid, sodium hydroxide, potassium carbonate, sodium carbonate, lemon 18 kinds of sodium, potassium citrate, trisodium bicarbonate, monosodium citrate, tripotassium phosphate, etc.
In addition to adjusting the pH of food, controlling acidity, and improving flavor, acidity regulators also have many other functional properties. Its effective application is mainly controlled by the required characteristics of food, usually organic acids and buffering salts. In addition, since many organic acids are normal components of food or participate in normal human metabolism, they are highly safe and widely used.
