Tartrazine

Description:
Tartrazine, also known as E102, is a synthetic lemon yellow azo dye commonly used as a food coloring agent. It is characterized by its bright yellow hue and is soluble in water, making it suitable for various applications in the food and beverage industry, including soft drinks, candies, and baked goods. Chemically, tartrazine is derived from coal tar and is known for its stability under acidic conditions, although it can degrade in alkaline environments. It has a molecular formula of C16H9N3NaO9S and a molecular weight of approximately 404.4 g/mol. Tartrazine is often used in combination with other colorants to achieve desired shades. However, it has been associated with allergic reactions in some individuals, particularly those with aspirin sensitivity or asthma. Regulatory agencies, such as the FDA and EFSA, have established acceptable daily intake levels for tartrazine, ensuring its safe use in food products. Despite its widespread use, there is ongoing debate regarding its potential health effects, prompting some consumers to seek alternatives.

    CAS:
    <p>Applications As a dye for wool and silks; as colorant in food, drugs, and cosmetics. In biochemistry as an adsorption-elution indicator for chloride estimations. Tartrazine (otherwise known as E number E102, C.I. 19140, or FD&amp;C Yellow 5) is a synthetic lemon yellow azo dye used as a food coloring. Tartrazine appears to cause the most allergic and intolerance reactions of all the azo dyes, particularly among asthmatics and those with an aspirin intolerance. Dyes and metabolites, Environmental Testing.A recent report has shown that Tartrazine may be useful in 3D bio-printing of organ-like architectures.<br>References Rowe, K.S., et al.: J.

  • Tartrazine

    CAS:
    <p>Tartrazine is a yellow synthetic food dye that has been used since the late 1800s. It is classified as a non-steroidal anti-inflammatory drug (NSAID). Tartrazine binds to the response element on DNA, which inhibits gene transcription and causes cell death. The rate constant for this reaction was determined using crystalline cellulose as the substrate. Mouse monoclonal antibodies were used to measure the rate constant of transfer reactions between tartrazine and optical sensor. The optimum concentration for tartrazine was determined using toxicity studies in rats.</p>
