Iron oxide is used in food sold and manufactured in a number of countries of the former Soviet Union, quite rarely. E172 is used to tint the finished product in red, black or yellow. But in the Russian Federation, such an additive is most often used to paint artificial caviar black.
This red dye is used much more widely in European countries. There he was certified for quality and safety. Local manufacturers use it to color confectionery products such as chocolate, cakes and candies ready for the mass consumer.
Main information
Oxide can often be found in the composition of a whole bunch of cosmetics of different directions. It was recognized as relatively non-toxic, and due to its moisture-resistant quality, the product successfully copes with prolonging the shelf life of products made with it.
Experts note that dyes produced by chemical methods have a number of advantages, because their threshold of sensitivity to various factors of external negative influence is much higher. In addition, such variations are famous for a more saturated tone, which is well preserved without inhibiting color richness.
If we compare E172 with various natural analogues, then the latter will fade against its background due to the weak resistance to oxygen molecules. For additives of natural origin, such a meeting is fatal – the product quickly deteriorates.
Scope of use
Most often, iron oxide is found in factories from the heavy industry. Here, the production of cast iron cannot do without it, because the substance acts as a raw material for obtaining a strong alloy. Also, the agent acts as an ammonia catalyst when it is necessary to carry out a series of reactions on an industrial scale.
In addition, the additive is necessary when creating ceramic products in order to give the final product the desired tone. It does not do without a component in the construction field, where it acts as a tinting assistant at the stage of cement mortar production.
Due to the fact that such a dye of synthetic origin does not have a characteristic taste or smell, it is used in the food industry, although many companies are trying to replace it with a natural counterpart.
This is explained by the fact that the substance does not carry any practical benefit, but it can be toxic.
To avoid overburdening your body with toxic ingredients, experts insist on using a strict daily dose. It is about 0,2 mg. If you exceed the established indicator, then the risks of getting a heart attack or stroke increase several times.
