Phosphoric acid is a mineral acid and consists of phosphorus, hydrogen and oxygen atoms. It is a crystalline and colorless, solid chemical compound. The aqueous solution has the consistency of must and is similar to syrup. Salts of this chemical compound are known as phosphate.

Phosphoric acid is commercially obtained by heating phosphate rocks extracted from underground with sulfuric acid under the necessary conditions. Phosphoric acid is actually two kinds. Some of them are food type phosphoric acid and some are phosphoric acid used in industry. Phosphoric acid caters to many different sectors and has a wide range of uses. It is mostly used in phosphate fertilizer production, pesticide production, metal cleaning, polishing sector and agriculture. It is also used to regulate the acidity of food products in the food industry. Since microorganisms do not develop in acidic environments, phosphoric acid is used as a preservative in this field. Phosphoric acid is very effective in acidifying beverages and preventing bacterial growth in processed foods.

Phosphoric acid causes serious discomfort on the skin when touched and on the eyes and respiratory tract when inhaled.

If you look at packaged foods, the contents are defined as acid regulators. Foods, whether in open space or indoor environment, pride over time. The reason for this is that bacteria and fungi start to form in the product and they multiply rapidly and spoil the food. Phosphoric acid and the like added to food products reduce the pH of the medium and prevent the growth and reproduction of microorganisms. In this way, the shelf life of the food is extended. Phosphoric acid is also used in yeast production. It is also phosphoric acid that provides the acidity of cola.

Phosphoric acid determination by titrimetric method is carried out in authorized laboratories within the scope of chemical tests. In these studies, the standards published by domestic and foreign organizations are complied with.
