Properties
Tripotassium phosphate is calcined at high temperature. It is white powder or granular at room temperature. It is hygroscopic, easily soluble in water, insoluble in alcohol, highly corrosive, and the aqueous solution is alkaline. reaction, the pH value of 1% aqueous solution is 11.8, the melting point is 1340°C, and the relative density is 2.564.
Purpose
Tripotassium phosphate is used in the food industry as an emulsifier, potassium fortifier, alkaline water for preparing pasta products, acidity regulator, meat product binder, buffer, and antioxidant enhancer. active agent, chelating agent.
Used in the manufacture of liquid soap, refined gasoline, high-quality paper, metal surface treatment, biological hydration treatment, phosphorus and potassium fertilizers. It can also be used as a boiler water softener, a high-efficiency liquid compound fertilizer and an auxiliary for recovering sulfur from acid gases in the production of synthetic rubber.
Acidity regulator
Acidity regulators, also known as pH regulators, are substances used to maintain or change the pH of food. It mainly contains acidifiers, alkalis and buffering salts needed to control food. Acidifiers have many functional properties to improve food quality, such as changing and maintaining the acidity of food and improving its flavor; increasing antioxidant effects and preventing food from rancidity; complexing with heavy metal ions, preventing oxidation or browning reactions, stabilizing color, reducing turbidity, enhanced gelling properties, etc. The acidity regulator inhibitors that have been approved for use in my country include: citric acid, lactic acid, tartaric acid, malic acid, metatartaric acid, phosphoric acid, acetic acid, hydrochloric acid, adipic acid, fumaric acid, sodium hydroxide, potassium carbonate, carbonic acid There are 18 kinds of sodium, sodium citrate, potassium citrate, trisodium bicarbonate, monosodium citrate, tripotassium phosphate, etc.
In addition to adjusting the pH of food, controlling acidity, and improving flavor, acidity regulators have many other functional properties. Its effective application is mainly controlled by the desired properties of the food, usually based on organic acids and buffering salts. And because many organic acids are normal components of food or participate in the normal metabolism of the human body, they are highly safe and widely used.
