What Are Uses of Phosphoric Acid In Food and Other Fileds
As one of the most commonly used food additives, food grade phosphoric acid is usually used as sour agent, yeast nutrition, widely used in the production of cola, beer, candy, salad oil, dairy products, beverages, etc… Phosphates are also the important food additive, which can be used as nutrient enhancer.
Uses of Phosphoric Acid in Coke. In carbonated beverages, it can interact with metal ions in water to form soluble salts, which can block the activity of metal ions, prevent beverage oxidation, spoilage and color change. So that the beverage can be stable for a longtime, and CO2 is well maintained.
Fertilizer grade phosphoric acid is the most important raw material for the production of phosphate fertilizer, such as superphosphate, potassium dihydrogen phosphate, as well as calcium dihydrogen phosphate feed nutrients. Used as reaction fertilizer in the soil around a granule acidification is generated that improves the utilization of phosphorus applied and available in the rhizosphere. Due to its nitrogen content, it is good for crops that require these nutrients in its initial phase.
Phosphoric acid can be used to prepare phosphorus-containing drugs, such as sodium glycerophosphate. It is an important ingredient in over the counter medications to combat nausea.
Mixed with zinc powder, phosphoric acid can form zinc phosphate, which is useful in temporary dental cement. In orthodontics, zinc is used as an etching solution to help clean and roughen the surface of teeth.

- The higher the concentration and purity of phosphoric acid the higher the crystallinity.
- Ternary medium-strong acid, ionized in three steps, not easy to volatilize, not easy to decompose, has a certain degree of oxidation and the common properties of acid.
Phosphoric acid is the IUPAC name for orthophosphoric acid. There is no difference between them, referring to the same chemical, both describing the same compound with the chemical formula H3PO4. The prefix -ortho is used to distinguish this acid from polyphosphoric acid.
It is a weak acid. Because it won’t completely dissociate in aqueous solution to obtain hydrogen ions. That is, when H3PO4 is dissolved in an aqueous solution, some moles of H3PO4 remian undissociated in solution and won’t fully ionized to produce hydrogen ions. The lower the hydrogen ions in the solution, the less acidic the compound is. Some data says that it is a medium-strong acid. It just means that its acidity is stronger in weak acids.
You will find phosphoric acid food additive in many sugar-sweetened carbonated or soft drinks. In addition to to helping create a strong flavor, it can also stop bacteria and mold from multiplying. Most known bacteria grow in the ideal PH range of 6.5 to 7.0. Adding liquid phosphoric acid to drinks and foods can lower the PH to 2.5. So as to reduce the chance of bacteria growing in drinks.
Thermal Process Phosphoric Acid
The thermal process uses yellow phosphorus produced by electrothermal method as raw material. After combustion and hydration, it is made into 85% thermal process phosphoric acid. Thermal production process with heat energy recovery device usually adopts a two-step method. That is, the combustion of phosphorus and hydration of P205 are carried out in two devices respectively. The key technical key of phosphorus burning equipment is how to prevent the heat exchange tube from being corroded by high temperature P2O5 gas, and to provide good heat transfer conditions at the same time.
Wet Process Phosphoric Acid
Phosphate rock is decomposed by inorganic acid(mainly sulfuric and hydrochloric acid). First, phosphoric acid for fertilizer is obtained. Then purify and remove impurities through various steps. Finally, it is concentrated to produce industrial grade phosphoric acid. At present, the main purification methods for preparing wet process phosphoric acid include chemical precipitation, ion exchange resin, crystallization, solvent precipitation and solvent extraction. Among them, the solvent extraction method has the characteristics of high purity of the obtained products, relatively simply production process and equipment, low energy consumption, low consumption of raw materials, large production capacity, good separation effect, high recovery rate and less environmental pollution. At the same time, the production process is easy to realize automation and continuity. And it is conductive to the comprehensive utilization of resources.
Food grade phosphoric acid is produced from industrial grade phosphoric acid containing various impurities. After dissolving industrial phosphoric acid in distilled water, the solution is purified to remove impurities such as, arsenic and heavy metals. Remove cations such as, As+, Cd+, Sr+, Pt+, Th+ and U+, anions such as Cl-, F- and SO42-, as well as organics. After filtration, when the filtrate meets the food-grade requirements, it is concentrated to obtain liquid phosphoric acid used in food.

The rust removal ability of phosphoric acid is relatively low. To make up for this shortcoming, derusting with phosphoric acid solution generally requires heating. The advantage is that the possibility of hydrogen embrittlement is small. Moreover, a small amount of solution remaining on the surface of the workpiece can be converted into an insoluble phosphate protective film. It is suitable for rust removal before welding and assembly parts are painted.
First of all, phosphoric acid is corrosive, so be safe when using it.
Within a safe dose, food additive phosphoric acid won’t cause harm to human health. However, if the intake is too large, it may cause harm to health, mainly including calcium deficiency and aggravating the burden on the liver and kidneys. After a large amount of intake, it may lead to the imbalance of calcium and phosphorus ratio in the body. And the situation of too high phosphorus and too little calcium can easily lead to calcium deficiency.
Phosphoric Acid Manufacturer And Supplier in China - Chemate
The core competitiveness of phosphoric acid is different due to the different end user goals. For general industrial-grade phosphate products, price and cost are the fundamental reasons that determine the type of phosphoric acid used by customers. For high-end fine phosphate products, because of the higher products value, the raw material cost factor isn’t very sensitive. On the contrary, the price of high-end fine phosphates varies greatly with the purity and quality, which makes prefer the quality when choosing the type of raw material phosphoric acid for sale.
