E133 is a synthetic type dye, the production of which takes place in the process of organic synthesis of coal tar. Outwardly, the dye looks like a red powder with a blue tint, which practically does not dissolve in.

From its main characteristics it is worth noting: a wide range of applications, acid resistance, thermal stability and a high level of light resistance.

Various manufacturers of the digestive sphere use E133 in combination with other types of dyes: if mixed with yellow, the result will be green at the input, in combination with red it will turn purple, in combination with purple or brown - black, in a duet with orange you will get brown. A duet of blue brilliant FCF dye with tartrazine (E101) is often found, in this way obtaining the most extensive palette of greens.

Purpose and scope

Brilliant Blue FCF has a wide range of applications. In industry food purpose E133 is used for staining pasta, bakery products, fruit ice, canned vegetables, canned fruits, dairy products, breakfast cereals, alcoholic beverages, without alcoholic beverages, various sweets, desserts, etc.

In the cosmetics industry, E133 is used in the production of decorative cosmetics, hair dyes, various creams, shampoos, and deodorants. Most often, Indian manufacturers resort to this additive to obtain brighter and more stable colors. In the textile industry, the dye is mainly used for dyeing silk and woolen fabrics. Brilliant blue FCF dye is used least of all in pharmaceuticals (coloring of capsule and tablet shells) and in the production of household chemicals.

The use of blue shiny FCF in the composition of medicinal products is prohibited.

Possible titles

Manufacturers can often hide E133 under other names, including:

• E-133;
• brilliant blue;
• aniline blue;
• blue #1;
• food blue-2;
• 42090;
• blue brilliant FCF.

Chemical composition and release form

The additive is produced synthetically, and the production usually uses coal tar, which is processed through organic synthesis. The additive has the following chemical formula: C 37 H 34 N 2 Na 2 O 9 S 3 .

It is very difficult to dissolve the additive in ordinary water, resulting in a blue or blue solution.

It is produced in the form of a granular powder without the presence of any odor. The additive is a combustible material and is highly resistant to alkaline media.

E133 can be produced in special woven bags, paper food bags, corrugated boxes. Regardless of the type of packaging, a plastic bag with a thickness of 0.08 millimeters is first placed inside. Each manufacturer has its own type of packaging.

Under no circumstances should other containers (not from the manufacturer) be used for storage.

Effect on the body: harm and benefit

The additive has an average level of danger to the human body.

The E133 dye is poorly absorbed by the body and ninety-five percent of the total absorbed dye is excreted along with food residues. If you consume Brilliant Blue FCF in large quantities and often, the feces acquire a greenish tint.

Abuse of the dye can provoke allergic reactions, asthma attacks, especially for people with hypersensitivity to aspirin. This dietary supplement has not been fully investigated to this day, therefore, the general range of side effects is not known.

There are currently no data on carcinogenicity and toxicity of the additive.

But, numerous studies (which were conducted on laboratory rats) have shown that this supplement has a positive effect on therapy for spinal cord injuries.

It should be noted that the blue brilliant FCF dye is a rather expensive synthetic agent, therefore, it is not actively used in industry, since it is not profitable.

Daily dosage

To date, a safe daily rate dye use, and it is twelve and a half milligrams per kilogram of body weight.

It is worth noting that for green peas, the amount of dye should not exceed one hundred milligrams per kilo of product. For canned puree from, the norm per kilogram should not exceed two hundred milligrams, but for the marinade, the amount of E133 per kilogram of product should not exceed three hundred milligrams. For pasta and other bread products, the norm is two hundred milligrams per kilo. In sauces, up to five hundred milligrams of dye per kilogram of sauce is allowed. For soft drinks and processed cheeses, the norm is one hundred milligrams per kilo.

Permission to use

Food group dye E-133 is acceptable for use in production in Russia, Ukraine and certain EU countries, but the additive is banned in Norway, Germany, Belgium, Denmark and France.

Main manufacturers

During the purchase period, it is important to choose the right manufacturer. Among the well-known foreign reliable manufacturers are: Sensient Technologies Corporation (America), ROHA and Vidhi Dyestuffs Mfg (India). Among the well-known and proven manufacturers in Russia for years, it is worth noting: Eco Resource and GIORD (St. Petersburg) and Teresa-Inter (Moscow).

It is important to remember that every synthetic additive or dye in any case harms the body (even if the manufacturers do not indicate this), therefore, if possible, products containing E133 should be avoided, especially if there are problems with the respiratory system, there are various chronic diseases, anomalies work of the liver, kidneys and intestines.

General characteristics and receipt

E133 is a food coloring of chemical origin in the form of a powder or granules, distinguishing feature which is blue with a reddish tint. The additive is poorly soluble in water, it is difficult to be absorbed by the human body and almost all of it is excreted along with undigested food.

Produced by organic synthesis. The raw material for the dye is coal tar. The level of harm to health is medium.

Purpose

Brilliant blue FCF is used in various industries for the purpose of painting in the desired color. Often it is mixed with other dyes to get a wider range of shades. It is used in the manufacture of food, cosmetics and textiles.

Benefit and harm

Currently, research on the E133 supplement is ongoing, but there is no scientific evidence of its toxic or carcinogenic effects yet. In many countries, the substance is used without prohibitions. But to say that the dye is completely safe is impossible.

It is harmful to people suffering from asthma and aspirin intolerance. It can provoke an attack of suffocation, acute allergic symptoms up to anaphylactic shock. The substance may adversely affect the behavior of children, causing headaches, increased activity levels, tearfulness, apathy.

When using candies and hard candies colored with E133, there is a risk of the substance entering the bloodstream. This can harm cells and their ability to produce energy from incoming food.

If we talk about the benefits of the substance, then E133 has shown the ability to help treat spinal cord injuries in rats. But research has not yet been carried out further due to the fact that the substance does not attract investors due to its low cost.

Usage and application

The food industry is not complete without the use of brilliant blue FCF. When mixed with other dyes, the substance gives different shades. Green color is obtained by combining E133 with E102, in combination with red and orange additives, black and Brown color, with the addition of red dye - purple.

Most often, with the help of E133, the following food products are stained:

• ice cream;
• sweets and desserts;
• canned fruits and vegetables;
• jellies and jams;
• dairy products;
• alcoholic and non-alcoholic drinks.
• The substance helps to color cosmetic products. It can be found in creams, hair dyes, deodorants, shampoos, soaps, mouth rinses, etc. The textile industry uses E133 for dyeing wool and silk.

Legislative regulation

Additive E133 can be used as a dye in Russia, USA, Australia, New Zealand and many European countries. The dye is also not banned in Ukraine and Belarus. The decision to use the substance in the Russian Federation was made in December 2005.

Countries such as Norway, France, Denmark, Belgium and Germany have abandoned the use of E133 food coloring and put it on the banned list due to potential health hazards.

Blue shiny FC with ( E-133) - food additive, synthetic dye. According to some reports, this additive has a carcinogenic effect.

The dye is included in the list of food additives allowed for use in food production (SanPiN 2.3.2.560-96), the list of food additives allowed for use in EU countries (for more details, see regulatory documents).

Blue brilliant FCF- triarylmethane dye obtained from coal tar by organic synthesis. Molecular formula of dye E-133: C37H34N2Na2O9S3. Looks like an additive E-133 is a red-blue powder, poorly soluble in water.

Metabolism and effects on the body

In the human body, the dye E-133 practically not absorbed and 95% of the absorbed dye leaves the body along with food debris.

Reacting with some bile pigments E-133 can give a green color to the remains of human life.

Additive E-133 can cause asthma attacks and allergic reactions, especially in people who are sensitive to aspirin. Dye research is currently underway E-133 for other side effects. At the same time, one study in laboratory rats showed that Blue Brilliant FCF could help treat spinal cord injuries.

Application of E-133

IN Food Industry dye E-133 often used in combination with tartrazine (food additive E-102) to produce various shades of green. 'Blue Brilliant FCF' is used as a coloring agent in the food industry for the production of ice cream, gelatin, desserts, some sweets, soft drinks. Less common additive E-133 found in dairy products and breakfast cereals.

In addition to the food industry, Blue Brilliant FCF is used in cosmetic products (included in creams, shampoos, deodorants, hair dyes, etc.)

Synthetic food dyes are representatives of several classes of organic compounds: azo dyes (tartrazine - E102; sunset yellow - E110; carmoisine - E122; crimson 4R - E124; shiny black - E151); triarylmethane dyes (proprietary blue V-E131; brilliant blue - E133; green S - E142); quinoline (yellow quinoline - E104); indigoid (indigo carmine - E132). All of these compounds are highly soluble in water, most form insoluble complexes with metal ions and are used in this form to color powdered products. Synthetic dyes have significant technological advantages over most natural dyes. They produce bright, easily reproducible colors and are less sensitive to the various stresses the material is subjected to during the process flow.

[Nechaev A.P., Traubenberg S.E., Kochetkova A.A., Food chemistry, 2003]

When using dyes, it should be remembered that they lose some of their color during food coloring and storage. Synthetic dyes of the triphenylmethane series (E131, E133, E142) in the process of coloring caramel discolor up to 10%, during storage - up to 18 %. In general, synthetic dyes are quite stable, with the exception of triphenylmethane dyes, which can discolor when alcoholic beverages are stored in the light, and indigo dye E132, which is unstable in drinks using invert sugar. The maximum permitted dosage of synthetic food colors individually or in total in mixtures is 500 g / t, the recommended dosage is 10-50 g / t of finished food product depending on the dye and the type of product being dyed. For Ponceau 4R, the maximum dosage is 50 g/t of finished product. Beforeto use synthetic dyes, it is necessary to ensure their toxicological safety.

Characteristics of the main synthetic dyes

Persistence of basic synthetic dyes

Notation me: ++ highly resistant; + stable; ± relatively stable; - unstable; -- unstable.

When manufacturing a food product using dyes, the following should be taken into account: the introduction of ethyl alcohol into the formulation does not change the intensity and shade of the color of the finished product, colored with synthetic dyes, with the exception of triarylmethane (E131, E133, E142), which can significantly discolor in alcoholic beverages;

Preparation and storage of dye solutions.

The recommended concentration of synthetic dye solutions is 1%. To prepare the solution, weigh 10.0 ± 0.2 g of dry dye and dissolve it with stirring in 0.5 l of drinking water. Water is recommended to be heated up to 60...80 °С, when working with blue dyes - up to 90...100 °С. It is advisable to use softened water. After complete dissolution of the dye (5 ... 10 minutes), 0.49 l of water is added to the resulting solution with stirring, and after cooling the solution to 20 ... 40 ° C, it is filtered through a layer of white cotton fabric (coarse calico). 10 g of this solution contains 0.1 g of dye.

Each container with the solution must be provided with a label containing the name of the dye, the composition of the solution and the date of preparation.

Solutions of food colorings are stored in a dark place at a temperature of 15 ... 25 ° C. Shelf life in normal conditions food production should not exceed two or three days.

The shelf life of dye solutions can be increased with the help of preservatives - sodium benzoate or potassium sorbate. In this case, 840 ml of water is used to prepare the dye solution. In one half of the remaining water (75 ml) dissolve 0.8 g of the preservative, and in the remaining 75 ml - 0.4 g citric acid. First, a preservative solution is poured into the dye solution, and then a citric acid solution and mixed thoroughly. Do not mix preservative and citric acid solutions before adding to the dye, as the resulting benzoic or sorbic acid may precipitate.
