E250: the effect on the body and the harm of this preservative
Е250, which is sodium nitrite, is a food additive with the properties of a preservative, antioxidant and color fixer. It is approved for use in many countries, including the EU, Russia and Ukraine. In its natural form, it is a fine powder of color of butter with sour taste, without residue dissolving in water and a good absorbing liquid.
The danger is that under the influence of oxygen in the air this compound oxidizes and becomes sodium nitrate, harmful to health in excessive amounts.
In its natural form it is contained in human saliva. In industry, it is obtained from the heated mass of sodium nitrate and calcium oxide, which is treated with gaseous sulfur dioxide.
Application of
Natural meat and fish, as well as semi-finished products, minced meat, canned food, sausages, sausages, smoked products and so on, irrespective of processing and method of packaging, inevitably lose marketability over time, acquiring an unpleasant grayish shade under the influence of oxygen. This is a normal reaction, but it does not suit the producers, since the non-commodity type does not contribute to product realization.
An alternative to food coloring, which gives an unnatural color, is the E250.It also prevents the development of bacteria, especially dangerous to the health of botulism.
The product retains a natural pinkish red color, the grease does not turn yellow and does not dry out.
Recently, the E250 began to process fruits and vegetables, giving them a glossy shine and retaining a bright, attractive color.
Is the preservative E250 harmful or not? According to the standards, it is added to the product together with the edible salt in an amount of no more than 0.6% of its mass. Or, a liquid salting mixture is used with the same proportion. In more cases, it is not only harmful, but can also lead to death.
In addition to the food industry, the additive is used in the manufacture of medicines and medicines that are necessary for the normalization of blood pressure, against asthma and other bronchopulmonary diseases.
It is also used in construction, adding to various types of concrete and paints( the color becomes brighter).
In the metal industry, the substance prevents rust.
In the light industry, the E250 is mixed with natural raw materials for the production of paper, fabric and rubber products to prevent the appearance of mold.
Effect on the body
The main effect on the body of the E250 is spasmolytic and vasodilating. The first is in demand in medicine for the treatment of cough, pulmonary hypertension, constipation, tachycardia, ischemia and arrhythmia, an aneurysm of the brain. With cyanide poisoning, this remedy is practically the only salvation. The second is good for hypertensive patients.
However, despite all the benefits, it is proved that the elevated temperature turns a relatively harmless sodium nitrite into carcinogenic nitrate and nitrosamine. Most of all, the stomach, intestines and lungs are vulnerable.
Most people do not consume meat, fish, minced meat and frozen semi-finished products in raw form. Any cooking is a more or less long heat treatment.
The conclusion is clear. Animal proteins are necessary for the body. Buy a pair of meat and freshly caught fish is an option far from everyone. Harm E250 for the body with excessive consumption of processed food products is that the internal organs develop malignant neoplasms.
And in a higher dosage( more than 0.5 g per 1 kg of weight) is generally a poison. A single lethal dose - 2-6 g.
In addition, in its natural form, this substance is explosive.
However, in most countries there is no ban on its use. Only certain norms and requirements are established.
