called phosphates of chemical bonds of different metals with phosphoric acid.Currently, there are many varieties of phosphates, which are used in various fields.No exception and potassium phosphate, which is often used as an antioxidant and bactericidal substances in the food industry.It should be noted that antioxidants are substances that inhibit the oxidation of other substances.For example, consider the bitten apple, which is on the air darkens.This happens because the oxygen in the air oxidizes the iron contained in the fruit.If phosphate pour in place to take a bite, the oxidation process will slow down many times.Thus, the metabolism is suppressed in the body of the bacteria.That is why it is used as a preservative.
should be noted that all of the compounds of phosphate, which are found in nature, are orthophosphates.Most often used in the food industry tripotassium phosphate (phosphoric acid salt), one of which is E340.In industry, tripotassium phosphate E340 called monophosphate is an approved food additive used as an acidity regulator, a moisture retaining agent and stabilizer latch coloring amplifier antioxidant action.This additive has the following chemical formula: KH2PO4, it is easily soluble in water and has the form of a granular white powder.
Phosphoric acid interacts with potassium carbonate, potassium phosphate forms a formula which K3PO4.It is used as a component in detergent additives and bakery products, soft drinks and dairy products, as well as soups, pastas and sauces, teas, cheese, meat and fish products, fast food.In addition, it is used as a stabilizer of green vegetables, because it maintains the acidity of the medium neutral.K3PO4 used in medicine to prevent and treat such diseases as hypophosphatemia, and in industrial production - as additives to paints, corrosion inhibitors and various drilling fluids.
should be noted that the potassium phosphate, part of the powders leads to increased toxic properties of surfactants.They begin to intensively penetrate into the human body through the skin, contribute to its degreasing, destroying cell membranes, thereby reducing the protective function of the skin.Surfactants, penetrating into the receptacle in the skin, enter the bloodstream and spread throughout the body, which contributes to a violation of the properties of the blood and immune system.
Thus, to date, potassium phosphate is used as phosphate fertilizer, as a component of liquid and powder detergents during drilling operations.Also it is used in the cement and textile industries, the latter in preparation for dyeing yarn or whitening in the food industry for loosening test, in medicine for the preparation of medicaments, tooth pastes or powders.Crystals of potassium phosphate are used as ferroelectric or piezoelectric materials, pesticides, additives for oils and other.
However, it is worth remembering that the phosphates adversely affect the human body, causing malfunctions in the event that a person is exposed to for a long time their influence.That is why many countries have abandoned the use of phosphates in the food and consumer industry.In our country, their use is allowed, so very often on the labels of various products or household tools can meet the designation E340, that is, potassium phosphate.
