There is an opinion that in combination with sodium benzoate can cause Quincke's edema, paralysis of the facial nerves and even cancer.

And such isolated cases did occur, however, when compliance with the required dosage, these severe consequences can be avoided.

Studies have shown that urticaria and rash from tartrazine appear only in 1 case out of 10,000 and in 1986 it was approved for use.

Tartrazine or E-102- yellow synthetic dye. By its nature it is coal tar and belongs to industrial waste. Its wide distribution tartrazine received due to its low cost (about $10/kg). Additive E-102- one of the cheapest synthetic dyes. Dye E-102 used in the food industry to give products a yellow color. Often mixed with other dyes to give products a specific color and shade.

Health effects of E-102 supplement

Tartrazine, a dye widely used in the food and pharmaceutical industries, causes significant destruction of cysteine and cystine. Urticaria associated with tartrazine was first described in 1957. The estimated incidence of urticarial reactions to tartrazine accounts for 5-10% of the total number of patients with urticaria. Merkelsson-Rosenthal syndrome (a combination of recurrent angioedema, fissures of the tongue and possible damage to the facial nerve), which is induced by tartrazine and/or sodium benzoate and disappears with an elimination diet, has been described. About the dangers of the supplement E-102 There is still much debate going on. So, for example, tartrazine in the recent past was banned for use in many European countries, but under pressure from the European Union the ban on the use of the dye E-102 and a number of other food additives was removed by EU Directive 94/36/EC. In 1986, studies of tartrazine were conducted in America, which showed that in a small group of people (1 in 10 thousand) due to the use of the additive E-102 Allergic reactions in the form of a skin rash may occur. Recent research conducted by the University of Southampton on behalf of the UK Food Standards Agency (FSA) has shown that consuming products containing tartrazine leads to increased hyperactivity and decreased concentration in children. There is often unverified information that the supplement E-102 can lead to a variety of negative consequences from headaches to cancerous tumors. These data are significantly exaggerated and not confirmed by official data. In most countries, the use of a dietary supplement E-102 in food products is strictly standardized, and usually amounts to 100–150 mg of dye per kilogram of the finished product. Tartrazine enhances the carcinogenic properties of sodium benzoate (Sodium Benzoate E-211).

Use of yellow dye "tatrazine" in the food industry

Characteristic:
Tartrazine E-102 is one of the cheapest synthetic dyes, obtained from coal mining waste - coal tar. It is used in food production to give them a yellow color. Due to its easy solubility in water, tartrazine E102 is also mixed with other dyes to obtain the desired shade or color.
This dietary supplement is not sensitive to sunlight. In a short period of time, when exposed to direct sunlight, tartrazine E102 breaks down into simple chemical compounds. In order for the properties of this synthetic azo dye to be preserved for a long time, it is kept in enamel or glass containers with tinted walls.
For a long time, the dye tartrazine was banned in some European countries, but in the 80s of the twentieth century it began to be widely used again in the food industry almost throughout the world.

Application:
Most often, tartrazine E102 can be found in yellow-colored drinks and in confectionery products - candies, cakes, pastries, jams, jellies, ice cream. In addition, the dye is added to all kinds of preserves - vegetables, fruits, mustard. In fermented milk products, tartrazine E102 is present in various yoghurts and desserts. Dye is also added to instant soups and purees. Tartrazine is also used in the pharmaceutical industry.
It is currently permitted in most European countries, including Russia and Ukraine. One of the determining factors for such popularity in the food industry is the low cost of the food additive.

Effect on the human body:
Scientists and industrialists have different opinions about the properties of tartrazine E102. Some European countries, fearing the negative impact of this dye, even banned its use in the manufacture of food products. According to most experts, this food additive provokes the destruction of cysteine and cystine. Back in 1957, doctors described urticaria caused by the use of tartrazine E102. Moreover, among all patients with urticaria, 5-10% are those who received a reaction to the dye.
The medical literature also describes Merkelsson-Rosenthal syndrome, expressed by damage to the facial nerve, the appearance of cracks in the tongue and Quincke's edema, provoked by nothing more than tartrazine. You can get out of this state only by staying on a strict diet.
In addition, studies have shown that one in ten thousand people develop skin rashes and other manifestations of an allergic reaction after consuming a dietary supplement.
When tartrazine E-102 is consumed by children, their hyperactivity increases and their concentration decreases.
In the vast majority of countries, regulations provide for a clear dose of tartrazine consumption. This is 100-150 mg of dye per 1 kilogram of the finished product or 7.5 milligrams per 1 kilogram of human weight.

It is no secret that nowadays in food production not only stabilizers, emulsifiers and preservatives are used, but also all kinds of dyes. Among them - tartrazine, which is known under the label E102. This rich yellow substance is obtained from coal tar, which is considered a waste product from the mining industry. The low cost of the synthesized dye E102 is a very compelling argument for many manufacturers to adopt this substance, without being interested in how dangerous it can be to human health.

Why is tartrazine so popular?

The main advantage of this substance is its low cost, since 1 kg of dye costs about $10. Dye E102 gives food products a very attractive yellow color, therefore it is very popular in many food industry enterprises, helping to promote various groups of products on the market. Another attractive feature of E102 from the point of view of manufacturers is that it dissolves easily in water and combines well with other food colorings, which allows you to experiment with giving food products a wide variety of shades.

Where is E102 dye used?

The absence of color and odor, as well as the apparent safety for health, led to the fact that since the 70s of the last century, tartrazine began to be widely used in the production of a wide variety of food products. First of all, we are talking about all kinds of carbonated drinks and ice cream, as well as canned fruits and vegetables, which, thanks to E102, acquire an appetizing appearance and are sold much more successfully than products without such an additive.

These days tartrazine can be found in various creams and jellies, yoghurts and jams, juices and sweets. This food additive is very widely used in the production of packaged soups, various breakfast cereals and mustard, which is the undisputed leader in the number of all kinds of food additives.

Along with this, E102 dye is also used in the chemical industry, as a filler for various types of paints, and is also included in many medications

What is the danger of E102?

From the very first days of the use of tartrazine in the food industry, cases of severe allergic reactions to this substance began to be identified. Approximately 7% of people who try products containing E102 dye at least once in their lives complain of hives - blisters that appear on various parts of the body and are very itchy. 2% of people who eat juice or ice cream with tartrazine develop Quincke's edema, which can be fatal.

However, allergies are far from the worst consequence of consuming products with E102 dye. What is much more dangerous is that, coming into contact with, this substance enhances its carcinogenic properties, which leads to the development of cancerous tumors. Most often, children who become victims of tartrazine are children who cannot resist bright yellow candies or yoghurts with this dangerous food additive.

It has also been proven that E102 is very difficult to remove from the body and tends to accumulate in tissues. It is for this reason that the dosage of tartrazine in food is strictly limited, and its amount in 1 kg of prepared food cannot exceed 100 mg. It has been proven that if the amount of tartrazine in the human body exceeds 7.5 mg per 1 kg of body weight, this can lead to death.
