E174 - an additive that is part of food and non-food products. It gives a special metallic shade to pastries, jewelry, and details of various designs. It is believed that all nutritional supplements are dangerous and can cause serious harm to the human body. Is this really what you need to know about E174 and how to apply the dye?
What you need to know about nutritional supplements?
Nutritional supplements - substances added to food during the production process. They are needed to improve various indicators of food - shelf life, appearance, aroma, texture and taste. Control over the use of food additives is carried out at the state level. Each country has a special list of recommendations and rules that manufacturers follow. In order to smooth out the differences, a sticker with information about the product in their native language is applied to imported goods. For example, in America, the full names of the additives are used for designation, and in the European Union the prefix "E" is used.
International standards that govern the use of food additives and impurities are introduced by a committee of experts from JECFA (International Agricultural Organization) and Codex Alimentarius. Standards undergo additional checks and only after that take effect.
To distinguish between nutritional supplements, a special Codex Alimentarius numbering system has been developed in the European Union. It has been operating from 1953 to the present day.
According to this classification, each additive is assigned an individual number that begins with the code "E". The first digit in the number indicates that the additive belongs to a particular group. Code E-1 indicates colorant ownership. E174 is a synthetic silver dye that belongs to the group of metallic colors.
This is a group of synthetic or natural substances. They are used for coloring food in various shades of the color palette. Initially, all dyes were of organic origin. For staining, juices of vegetables and fruits, extracts or infusions from leaves, roots or pericarp of flowers, crushed flowers, etc. were used.
Some shades (for example, metallic) simply do not have plant analogues. You can only add a silver tint to a food product using synthetic food coloring.
In the modern gastronomic industry, the vast majority of additives are of synthetic origin. This is due to the rapid development of science. Creating an artificial dye turned out to be much simpler, faster, and cheaper than extracting it from plant products.
General characteristics of E174
E174 (silver) - silver dye. It has not only a coloring, but also a disinfecting effect. Silver is rarely used in the food industry due to its high cost and minimal distribution. The main field of application of the additive is the jewelry industry. Also, the dye is used in the manufacture of various decor elements, children's toys, interior items, large construction projects, which need to be given a silver tint.
E174 are classified as conditionally safe additives. The substance is resistant to various acids and aggressive environments. Scientists have proven that the supplement can be used even in surgery. E174 makes it possible to introduce silver into the human body without any threat to health and tremendous stress for all internal systems. Moreover, the metal blocks purulent and inflammatory processes, which helps the patient more likely to recover after surgery.
Silver enters the human body along with water. Due to its antibacterial properties, the substance is often used to disinfect liquids.
It should be noted that the concentration of silver in the liquid is enormously small and cannot significantly affect the health of a living organism.
Silver is a heavy metal that is mined from clay deposits of the earth's crust. The substance is characterized by low reactivity, so the dye does not dissolve in hydrochloric / sulfuric acids. Dissolution is possible only in the presence of free oxygen in hydrochloric acid or in an oxidizing environment. The dye does not dissolve in pure alcohol, and upon contact of substances a specific chloride film is formed.
Features of application of E174
Silver dye is used for the same purpose as aluminum. The substance gives the product a silver tint with a glossy sheen. In addition to decoration, E174 can be useful in the alcohol industry.
The main advantage of the metal is its disinfecting effect. The substance can be used to cleanse fluids and even treat certain diseases.
Silver is an excellent catalyst for the production of edible oils, so it can be used in the production of strong alcohol (vodka / liquor) and grape wines.
The effect of dyes on the human body
The permissible concentration of silver ions in the body is 7 milligrams per day. Regular use of the substance in large quantities can cause skin pigmentation. Derma acquires a bluish-metallic hue, an unhealthy appearance and increased sensitivity. The condition can be corrected by a long and intensive therapeutic course.
Also, an excess of silver is fraught with a deterioration in the functionality of the kidneys, nervous system, and other organs of the human body. Diseases can be accompanied by severe headache, lethargy, general body fatigue and a sharp decrease in performance. Local pain, confusion and impaired mental ability are possible.
E174 is forbidden to be added to food for babies, since excess dosage of silver can adversely affect the health of the child.
Nutritional supplements extend the shelf life of products, make them more tasty and attractive. They also ensure the quality of goods at some stages of production - from processing to packaging and storage. Often, it is nutritional supplements that are suspected of a sharp increase in cases of allergies, asthma and other diseases in the 21st century, but there is no clear scientific evidence for this.
Independent media outlets often appear condemning the use of preservatives. Some journalists claim that "E" is the main cause of illness, which mislead the public. All preservatives labeled with the “E” code have been thoroughly tested for safety and compliance with international standards. Even if we assume that preservatives are toxic, then the concentration in which they are used, just can not harm a person.
Excess doses are calculated in milligrams or tenths of a gram per kilogram of body. Hazardous dyes never get in such quantities in food, so the risk of side effects is minimal.
Each person is individual, and the reaction of his body to a particular food supplement may be specific. This is important to consider when studying the effects of E174 and other preservatives on the body. State food control authorities simply will not allow the appearance of dangerous goods on the market. To date, there is not a single industrial product in which there would be no safe E-additives. Some of them can be found in organic vegetable vegetables and fruits (most synthetic components have a plant analog). Therefore, do not give up the usual diet and enjoy the benefits of modern civilization.
