Tartrazine dye has been implicated in a variety of adverse reactions. There is a high correlation between aspirin sensitivity and tartrazine sensitivity but the reverse is exceedingly rare. Herewith is presented a case where repeated occult exposures to tartrazine yellow dye in a patient who could take aspirin with impunity was uncovered by a deduction. The ubiquitous nature and protean manifes...

Tartrazine is a synthetic organic azo dye widely used in food and pharmaceutical products. The current study aimed to evaluate the possible adverse effect of this coloring food additive on renal and hepatic structures and functions. Also, the genotoxic potential of tartrazine on white blood cells was investigated using comet assay. Twenty adult male Wistar rats were grouped into two groups of 1...

The effects of tartrazine on the synthesis of prostaglandin-like substances (PGLS) from arachidonic acid in isolated perfused guinea pig lung, and on the contractile responses of guinea pig tracheal tissues induced by histamine, acetylcholine, bradykinin, serotonin and prostaglandin F2 alpha were studied. The synthesis of PGLS from arachidonic acid was not inhibited by tartrazine. The contracti...

Multiple double blind placebo controlled challenges with tartrazine 50 mg (three challenges) and glucose placebo (three challenges) were performed in 12 children with atopic eczema aged 1 to 6 years. The children were selected on the basis of severity (regular clinic attenders) and a parental history that tartrazine provoked worsening of the eczema. In only one patient did the three tartrazine ...

The insoluble multi-walled carbon nanotubes (MWNT) was successfully dispersed into water in the presence of hydrophobic surfactant. After that, MWNT film-coated glassy carbon electrode (GCE) was achieved via dip-coating and evaporating water. Owing to huge surface area, high sorption capacity and subtle electronic properties, MWNT film exhibits highly efficient accumulation efficiency as well a...

Using routine histological procedures, it is difficult to distinguish osteoid from calcified bone and woven from lamellar bone in decalcified preparations of bone. Although several alternatives are available to overcome the first difficulty, differential staining of woven and lamellar bone has not been described. In 1958, Attwood modified Lendrum's (1947) phloxine-tartrazine stain to identify f...

Tartrazine is an orange-colored, water soluble powder widely used in food products, drugs and cosmetics. The acceptable daily intake (ADI) oh human is 0-7.5 mg/kg body weight. The objective of our study was to examine the genotoxic effect of different Tartrazine concentrations of fresh whole blood cells; by using alkaline single-cell gel electrophoresis (SCGE), also called the comet assay. This...

The literature was reviewed to determine the incidence of idiosyncratic reactions to tartrazine. From 4% to 14% of individuals with asthma or allergies or both and from 7% to 20% of persons who are sensitive to acetylsalicylic acid may react to this dye. The mechanism of such reactions is unknown. Pharmaceutical manufacturers and distributors were surveyed and a list was prepared of approximate...

Laccase enzyme, a commonly used enzyme for the construction of biosensors for phenolic compounds was used for the first time to develop a new biosensor for the determination of the azo-dye tartrazine. The electrochemical biosensor was based on the immobilization of laccase on functionalized methacrylate-acrylate microspheres. The biosensor membrane is a composite of the laccase conjugated micro...

A new method is reported for sensitive determination of tartrazine in the food samples. The method is based on the catalytic effect of silver nanoparticle (AgNPs) on the oxidation reaction of tartrazine by potassium iodate in the acetate buffer medium. The reaction is followed spectrophotometrically by measuring the change in absorbance (ΔA) at 420 nm using a fixed time method (70 s). The react...
