Characteristic

E 530 in the form of a loose white powder is called light magnesium oxide (easily absorbs water), and in the form of a thick white powder is known as heavy magnesium oxide. The additive is obtained by heating magnesite, dolomite, MgSO4 or deposited MgCO3 and Mg (OH) 2 with the formation of impurities in the form of calcium oxide.

Use

Magnesium oxide is used as an additive to prevent sticking and lump formation. It is used in the production of milk powder (not more than 10 mg / kg), dry cream (not more than 1000 mg / kg) for vending machines together with other anti-caking agents or alone. In chocolate and cocoa products, the additive is used as an anti-caking and anti-lump agent (not more than 70 g / kg of dry non-fat). It is also used as a catalyst in the process of hydrogenation of vegetable oils (the residue in the product is not more than 0.1 mg / kg).

Magnesium oxide is also used in medicine (chemical neutralizer of stomach acids, osmotic laxative). In construction - for the manufacture of combined systems of refractory materials, for the production of cements; in the electronics industry - as an abrasive for surface cleaning; in gymnastics - magnesium powder, preventing the equipment from slipping out of the hands of athletes.

Impact on humans

When working with magnesium oxide it is mandatory to take the necessary measures to protect the respiratory organs and eyes (possible irritation of the mucous membranes and the appearance of cough, also redness of the eyes). Accidental ingestion of magnesium oxide can lead to intestinal upset.

In food, the amount of the substance is limited. The additive E 530 is recognized as safe for use in food production.
