What Is Phosphoric Acid?
Phosphoric acid, also known as orthophosphoric acid or phosphoric (V) acid. It is normally encountered as a colorless, odorless syrup of 85% concentration in water.
It was first studied in 1772 and was studied by French chemist Lavoisier. About a hundred years later, German scientist Liebig further explored the application of phosphoric acid and phosphate as fertilizer. Since then, the phosphoric acid has entered the era of large-scale production.
It can be used as sour taste agent and yeast nutrient in food, is a very common food additive, sometimes called phosphate sodas or phosphates.
Application in food:
Food-grade phosphoric acid (additive E338) is used to acidify foods and beverages such as various colas and jams, providing a tangy or sour taste. It is used in sugared and sugar free beverages, baked goods, fortified meat products, dairy products, ready to eat foods, etc.
Application in agriculture:
Phosphoric acid is an important raw material for the production of phosphate fertilizer and feed nutrients.
Application in industry:
Phosphoric acid is an important chemical raw material.
- As a protective film to protect metal surface.
- As a raw material of chemical polishing agent.
- As a raw material of washing products and pesticides.
- As a raw material of flame retardant.
Application in medicine:
Phosphoric acid can be used to prepare phosphorus containing drugs, such as sodium glycerophosphate.
Is phosphoric acid safe?
Although there has been controversy about this issue, in fact, we often take it in our diet.
Here are examples of estimated phosphorus content (per 100mg) for selected foods: Apple-11；Baked biscuits-470；Chicken-200；Crackers- 302；Cola-11；Cereals-150 ~ 300.
So it’s important to be moderate. In the case of moderate intake of phosphoric acid, it’s completely safe.
According to the Research Report of New York（GLOBE NEWSWIRE）-Facts and Factors，the global Phosphoric Acid market was estimated at USD 45 Billion in 2019 and is expected to reach USD 60 Billion by 2026. The global Phosphoric Acid market is expected to grow at a compound annual growth rate (CAGR) of 4.0% from 2020 to 2027. The rise in the global population is driving demand for food which is anticipated to propel the growth of the fertilizer industry. The growth of the fertilizer market is boosting the demand for phosphoric acid.
Food grade phosphoric acid is estimated to gain traction in the coming period. The demand from the agriculture industry is fueling the demand for food-grade acid.
