Brilliant blue dye (brilliant blue, food blue, aniline blue) is a food additive of synthetic origin with code E133. The substance is produced from coal tar by organic synthesis. It has no analogues in nature.

The dye is a purple or blue powder. The substance is resistant to light and alkaline environment, changes color in acid.

Application of blue glitter dye

E133 is widely used in the food industry due to its low cost and ability to combine with other dyes to produce shades of purple, black and brown. In addition, with the help of this substance, you can restore the lost color of the product and give it an appetizing and attractive appearance.

Dye "Brilliant Blue" is found in the composition:

confectionery;
soft drinks, alcoholic cocktails;
seafood, fish;
ice cream;
dry breakfasts.

The substance is also used in cosmetics, often as a component of shampoos, hair dyes, soaps, shower gels.

The impact of dye E133 on humans

Scientific research on the safety of the E133 dye has not yet been completed, but its use is permitted in the CIS countries, Russia, the USA, and Australia. The substance belongs to the class of moderately hazardous food additives, its amount per 1 kg of adult body weight should not exceed 4.8 mg.

The dye is forbidden to be used by people who are sensitive to aspirin, asthma patients, prone to allergies. The substance is not absorbed in the body, and is excreted naturally with food debris.

General characteristics and receipt

E133 is a food coloring of chemical origin in the form of a powder or granules, the distinguishing feature of which is a blue color 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. Used in the manufacture food products, 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 cheapness.

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. A green color is obtained by combining E133 with E102, in combination with red and orange additives, black and brown come out, 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;
milk 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.

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 various types the impacts to which the material is subjected during the process flow.

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 may discolour during storage. alcoholic beverages in the light, and indigo dye E132, which is unstable in drinks using invert sugar. The maximum permitted dosage of synthetic food colorings individually or in total in mixtures is 500 g/t, the recommended dosage is 10-50 g/t of the finished food product, depending on the coloring agent and the type of coloring product. For Ponceau 4R, the maximum dosage is 50 g/t finished products. Beforeto use synthetic dyes, it is necessary to ensure their toxicological safety.

In the production of a food product using dyes, the following must be taken into account: the introduction of ethyl alcohol into the formulation does not change the intensity and shade of the color finished product dyed 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. The shelf life under normal conditions of food production should not exceed two to 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 dye, as the resulting benzoic or sorbic acid may precipitate.

Characterized by some properties that are not particularly favorable for human health, the E133 Blue Brilliant FCF dye is still included in the list of food additives that are not prohibited for use in food production. That is why today this substance is often used in Russia, Ukraine and in many EU countries.

Moreover, there is even daily rate consumption of dye E133 Blue brilliant FCF - about 12 and a half mg / kg of body weight. In the food industry, this artificial color is most often used in the production of canned fruits and vegetables. So, for example, for canned green peas, the amount of Blue Brilliant FCF cannot exceed 100 mg/kg, and in applesauce the content of this substance should not exceed 200 mg/kg. In the manufacture of jellies and jams, an indicator below 200 mg / kg is considered the norm, and in pickled cucumbers E133 is present in an amount of 300 mg / kg, but not more.

On the territory of our country, the coloring properties of the E133 Blue Brilliant FCF dye are widely used in dyeing fruit ice, ice cream and numerous desserts. In the production of alcoholic beverages, effervescent and fruit wines, as well as pasta and bakery products, the amount of this substance should not exceed the established norm of 200 mg / kg. By the way, the composition of the E133 Blue Brilliant FCF dye has much in common with the substances contained in the dye, so their properties are almost identical.

In addition to the food industry, the use of E133 is also quite common in cosmetology and pharmaceuticals. Quite often, some medicines are stained with it, and they are also used in the production of decorative cosmetics. In addition, the dye E133 Blue Brilliant FCF is used in Russia for dyeing silk and wool, as well as many cleaning products.

The composition of the dye E133 Blue brilliant FCF

The composition of the dye E133 Blue brilliant FCF directly depends on the method of its preparation, due to which this substance belongs to food dyes of synthetic origin. Powder or granulate of purple or red-blue color is obtained from coal tar by organic synthesis.

In water, this dye dissolves with difficulty, forming a blue solution as a result. And when mixed with other dyes, completely different shades can be obtained. So, for example, when mixed with yellow dye, Brilliant Blue gives a green tint, with red - purple, and with orange and red - black and brown.

Dye damage E133 Brilliant blue FCF

Man is known possible harm dye E133 Blue brilliant FCF for the body, so this additive is classified as a medium hazardous substance. It has been proven that it negatively affects human health, provoking the occurrence of asthma attacks and allergic reactions. It is forbidden to use products with E133 for people allergic to aspirin.

In addition, according to some data, the harm of the E133 Blue Brilliant FCF dye lies in the fact that it is called a carcinogen, but, fortunately, after numerous studies, this statement was not confirmed.
