Tartrazine: Uses, Controversies, and Health Implications of the Popular Synthetic Food Colorant

admin Jan 2, 2025

Tartrazine, also known as E102 in Europe, is one of the most common synthetic food colorants in the world. It is a lemon-yellow Azo dye that is mainly used for coloring processed foods, cosmetics, medications, and even textiles. Though the bright color of this dye makes it so commercially appealing to food manufacturers and Tartrazine food color manufacturers, this dye, however, has raised medical concerns about its health implications. Let’s explore what Tartrazine is, its usage, controversies in its usage, and how it impacts health.

What is Tartrazine?

Tartrazine is an artificial Azo dye whose chemical nature is defined by a feature known as an Azo group: a group having the structure -N=N-. This defines the bright yellow color of the compound. It is usually described chemically as trisodium (4E)-5-oxo. -1-(4-sulfonatophenyl)-4-[(4-sulfonatophenyl) hydrazono]-3-pyrazolecarboxylate. It was first identified in the late 19th century and then manufactured on an industrial scale, primarily because of its efficiency, stability, and cost-effectiveness in colorant applications.

The bright yellow color it produces is associated with a variety of foods and drinks, including carbonated beverages, chips, candies, sauces, cereals, and baked goods. Furthermore, Tartrazine is used in the production of green shades by mixing it with blue dyes, thus increasing its range.

Applications of Tartrazine

Tartrazine is highly consumed across various industries such as food, cosmetics, pharmaceuticals, and textiles. Some of the common applications include:

Food Industry

• Processed Foods: It is usually applied as a bright yellow-orange color to which various foodstuffs are added, such as candies, sodas, flavoured snacks, sauces, and instant foods.
• Baked Goods: Tartrazine imparts bright color in cakes, biscuits, and other baked items, therefore making them look more appealing.
• Dairy Products: In cheese and yogurt, it imparts shades to make the color standard, thus appearing uniform and attractive.
• Condiments and Sauces: Yellow mustards and salad dressings, among others, contain Tartrazine to provide a bright yellow color.

Cosmetics and Personal Care Products

Tartrazine is applied in cosmetics such as lipsticks, nail polish, and shampoos to give them a bright, attractive color. Some lotions and creams also have it.

Pharmaceuticals

Some over-the-counter and prescription medicines utilize the coating of Tartrazine or use it as a colorant for the liquid solutions to make them distinctly different in color.

Textile Industry

In the textile industry, Tartrazine is used as a dye on fabrics that may confer a yellow color or be part of the formulation of mixed dyes to come up with specific colors.

Controversies Over Tartrazine

Tartrazine has been widely criticized for health concerns. Various health organizations around the world have established numerous ADI guidelines for it; however, controversy does exist in terms of allergic risk and impacts on behavioural occurrences for children.

Allergy and Sensitivity Reactions

Some people exhibit allergic symptoms to Tartrazine, including hives (urticaria), itching, and asthma-like symptoms. Research evidence seems to suggest that intolerance to aspirin predisposes someone to adverse reactions to Tartrazine, although the incidence is relatively low.

These effects are believed to be due to an immune reaction to the dye or its metabolites, although further work would be needed to fully elucidate the pathophysiology.

Hyperactivity in Children

The most fiercely debated controversy about Tartrazine is its potential link to hyperactivity in children. In the year 2007, UK Food Standards Agency research established a definitive link between artificial food colors, including Tartrazine, and the hyperactive nature of children. Subsequently, the European Union compelled the use of warning labels on all products manufactured from this substance with the disclaimer that it “may hurt activity and attention in children.”

Despite coverage in the media, the evidence has not been definitively proven for widespread acceptance, as some studies have shown a lack of a significant connection between Tartrazine and hyperactivity. Regulation agencies, such as the U.S. Food and Drug Administration, have evaluated the evidence and concluded that Tartrazine is safe to consume in the majority of people but requires careful attention from sensitive individuals.

Regulatory Response

Because of controversies, some countries have banned its use, either limiting it or requiring that products containing it apply a warning label. Such is the case in the European Union, whose regulations for the substance’s use are quite strict, containing that it must have a label that informs consumers of risks for hyperactivity in children.

The FDA in the United States permits Tartrazine in food and medicine if it conforms to standards of purity and labelling. Tartrazine must be declared as an ingredient in a food product, which makes it easy for sensitive people to avoid it.

Other countries include Canada and Australia, where the food safety authorities also regulate its use and require listing on product labels. Meanwhile, some products that are marketed as “natural” or “organic” avoid synthetic dyes completely.

Health Effects of Tartrazine

The health effects of Tartrazine have often been debated. Most studies conclude that it is safe for the general population at permitted levels, but there are some concerns.

Potential Carcinogenicity

The azo dyes, of which Tartrazine is an example, have long been associated with potential concerns over carcinogenicity, though evidence directly linking these dyes to cancer does not exist. Even so, regulatory bodies like the WHO and FDA have concluded that Tartrazine is safe for use in food by humans at the acceptable daily intake set for it, which is 7.5 mg per kilogram of body weight.

Some researchers reported that Tartrazine is deleterious to DNA or may induce oxidative stress in animals, but this has not been proven to occur within humans.

Behavioural Effects

As explained earlier, the food coloring Tartrazine has been correlated with behavioural disorders, especially in children, although, when reviewed by science practitioners, the degree of this association remains controversial. Some studies suggest a synergistic effect may exist between Tartrazine and other food additives that cause hyperactivity or attention deficit disorders.

Immune Responses

In sensitive individuals, Tartrazine can induce immune reactions that include skin rashes, respiratory disorders, or gastrointestinal problems. Such reactions are hardly ever met, yet for individuals who may have sensitivities toward food or drug allergies, this is one of the remarkable findings.

In addition to the implications for human health, Tartrazine has environmental significance. During manufacturing and disposal procedures, Azo dyes, such as Tartrazine, can pollute waterways through elimination processes. Products obtained during the breakdown of Azo dyes are usually toxic to aquatic species. The persistence of Azo dyes within the environment has become an issue that environmental scientists always raise.

It is a synthetic food colorant; Tartrazine is widely used because of its bright yellow hue and economical cost. Because this additive could create vibrant colors at a low cost, the majority of Tartrazine food color manufacturers supply the material to industries such as food and beverages, cosmetics, and pharmaceuticals. Although regulatory bodies around the world generally think it is safe for consumption within limits, due to allergic reactions, potential behavioural effects in children, and environmental impact, great concern still exists. Consequently, due to consumers becoming increasingly vigilant about the dangers of synthetic additives, there is an increasing call for natural alternatives to such artificial colorants as Tartrazine. Therefore, manufacturers of food colourings containing Tartrazine are being compelled to reformulate their products or come up with natural, safer products to quench the consumer’s thirst.

Types And Applications Of Synthetic Food Colours

admin Feb 16, 2023

Adding colours to food plays with both episodic as well as semantic memory. Food colourants are additive dyes that impart various appealing hues to the food substance. Food colours can be natural or synthetic. Natural food colours are the ones that are produced naturally by extracting colours from organic veggies. The other class of colours falls as inorganic or synthetic colours which are produced chemically. The precursor compounds are modified through a wide range of chemical processes. How our brain reflexes, we expect to acquire the taste of food as it appears. Neurologically we perceive that any black food is either burnt or maybe bitter, if any food has a tint of orange in it that means it is tangy, red food automatically appears to be spicy and there are many more perceptions of food we conjure. Synthetic colours are classified into Azo dyes, triarylmethane dyes and chemically related colours.

All the colourants or food dyes are authorised as food additives in the EU. EU is the packaging that approves the food additives and these are mostly written with the prefix of E. This authorisation is given by INS (International Numbering System for Food Additives), a European-based naming system for food additives. Azo dyes include tartrazine, amaranth, Allura red AC et cetera. Triarylmethane dyes include patent blue, brilliant blue and green S and chemically related colours are like quinoline yellow, erythrosine, etc.

JECFA (Joint FAO/WHO Expert Committee on Food Additives) administered the globally accepted guidelines to evaluate the safety of these food additives.

Alliance Organics LLP manufactures food colour dyes that comply with these guidelines considering the dosage limit of food additives. Food colours vary and they are primary colours, blended food colours and lake colours. This segregation of colours is done based on their solubility.

Primary colours are water soluble so they get washed off easily. Citing a classic example, lollipops that ink the tongue of kids are dyed using water-soluble colours.

The other class is Lake Colours. Lake colours have oil coating over them so they don’t get washed off easily when encountered with water or moisture. Mostly the seasoned food consists of Lake colours.

This prevents the soiling of hands as the colour doesn’t get impregnated on the surfaces. The major consumption of Lake colours is done by the food industry, more specifically the pet food industry. The Pet food industry has no confined dosage of consumption of food colours which ultimately makes the pet food manufacturers use tempting food tints which thereby leads to greater demands from the masses.

About Blended Food Colours – Artificial, Natural

admin Feb 16, 2023

Food colouring, often known as a colour additive chemical, is any dye, pigment or chemical that adds colour to food or drink.

They are available in a variety of forms, including powders, liquids, powders, pastes and gels. Food colouring is used in both commercial food production and home cookery.

Blended Food Colours are a blend of two or more food colouring ingredients in various combinations. Because natural colours are scarce, some hues are synthesized chemically using various chemicals. These food colours are commonly used in the milk and processed food industries.

Food colourings are classified into two types:

• Artificial
• Natural

After all, natural colours are preferred considering they are derived entirely from plants. When compared to artificial flavouring, natural colouring appears less dynamic. This, however, does not affect the aroma of your food.

Alliance Organics are distinct exporters of Food Colours that are approved for use in food items. These colours are added to various drinks, dessert shops, and pastry kitchen items that are water-soluble. Furthermore, these colours are made using high-quality, hygienic chemicals. These colours are pure and are available in a variety of hues. They employ high-quality raw materials to manufacture the highest-quality products. We provide the most competitive prices on the market for these food colours.

Blended colours, as the name implies, are created by combining two or more types of various food colours to achieve the desired colour effect. Because the amount of organic food colours on the market is restricted, a huge variety of hues are synthesized artificially using various chemicals.

Blended food colours are a combination of two or more water-soluble food colouring chemicals that can be blended in a variety of ways to produce a wide range of hues. The process of producing blended food colours entails extensive in-house research, with considerable care made to guarantee that they meet international food quality requirements. Blended food colours are the most commonly used goods because they are non-reactive and more stable than other colours.

Blended food colours can also be made to meet the specific needs of consumers.
