Phosphoric Acid

Product Analysis

Phosphoric acid is a type of food additive that is commonly used to control and adjust pH in a variety of foods and beverages. Considering that this chemical is a type of food, it should not be mistaken as a dangerous acid. In fact, if used in the correct combination, phosphoric acid is completely safe for use in the food industry.

Phosphoric acid is a colorless, odorless crystalline liquid made from the mineral phosphorus, which occurs naturally in the body. This substance works by combining calcium to create strong bones and teeth. It also improves kidney function and how your body uses and stores energy.

This acid, also known as orthophosphoric acid or phosphoric acid (V), is a mineral acid that has the chemical formula H3PO4.

Phosphoric acid, in addition to being a chemical reagent, has various uses, including as a rust inhibitor, food additive, and also in the production of dental products and orthotopic etictal, electrolyte, toothpaste, soap and detergent, water purification, industrial pen, materials Primary fertilizers and components of household cleaning products

Phosphoric acid is used to acidify foods and drinks such as soft drinks to provide a spicy and sour taste. Its various salts such as monocalcium phosphate are used as yeast ingredients.


Phosphoric Acid in food


Phosphoric acid may be used to remove rust from rusted iron, tool steel, or other surfaces. This acid changes the reddish-brown iron(III) oxide Fe2O3 (rust) to iron phosphate FePO4. The empirical formula of this reaction is as follows:

2 H3PO4 + Fe2O3 → 2 FePO4 + 3 H2O

Food grade phosphoric acid has a pH below 1, which means that it must be dispensed by authorized professionals, and of course that everyone who comes into contact with this chemical in the production process must use appropriate protective clothing and equipment.

Food grade phosphoric acid is used as an additive to acidify foods and beverages such as colas and jams, providing a tangy or sour flavor and also acting as a preservative.

Beverages containing phosphoric acid, including Coca-Cola, are sometimes called phosphated beverages or phosphates.

Industrially, phosphoric acid can be used in fertilizers, detergents, medicines and softeners. Also, the following are part of its uses:

  • As a pH regulator in cosmetics and skin care products
  • As a disinfectant agent in the dairy and food industries
  • In stainless materials with a combination of phosphate coating
  • To prevent the oxidation of iron using the parkerization process
  • in phosphoric acid fuel cells
  • in the production of activated carbon
  • In compound semiconductor processing

In the following, some important foods that contain phosphoric acid are mentioned:

  • Red Meat
  • Egg
  • Drinks
  • Dairy products
  • Baking soda
  • Processed foods
  • Yeast
  • Bird meat

Side effects of phosphoric acid


Phosphoric acid in soft drinks can cause tooth erosion. It can also contribute to the formation of kidney stones, especially in people who already have kidney stones.

The link between regular and long-term consumption of soft drinks and osteoporosis in middle age in women (and even men) has been proven.

It is thought that this is due to the presence of phosphoric acid, so that its excessive consumption is directly related to the decrease in bone density. Also, in moderate concentrations, phosphoric acid solutions cause skin irritation.
