Papaya (C. papaya) is a rich source of bioactive compounds. However, fruit content varies greatly depending on factors such as the variety and growing location. In this study, three yellow-fleshed papaya cultivars (L??ie Gold, Rainbow, Kapoho Solo) two red-fleshed (Sunset Sunrise) were harvested from different locations throughout Hawaiian Islands analyzed for their mineral carotenoid using ICP...

Introduction: In this study, we evaluated the antidiabetic and antidiabetogenic effect of saffron against diabetes induced by artificial dye tartrazine on normal male rats. Methods: Dried saffron was macerated for 12 hours in distilled water before usage and crude extract was used to treat male rats. Rats were divided into 5 groups consisted of 6 rats and treatment was performed daily a...

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...

We introduce a sensitive, rapid, label-free and general fluorescent method for the determination of tartrazine by competitive binding to reduced graphene oxide (rGO) against fluorescein, and the fluorescence recovery upon fluorescein desorption from rGO provides a quantitative readout for tartrazine, giving a detection limit of 0.53 ng mL(-1).

The clinical diagnosis of hypersensitivity to the food dye tartrazine in 16 subjects correlated with levels of tartrazine-specific IgD antibodies determined by a solid phase radioimmunoassay inhibition test. This is the first study associating hypersensitivity to a low molecular weight chemical with an antibody response of the IgD class. There was little or no correlation between clinical sensi...

Finding natural food coloring options from plant-based sources to substitute artificial dyes is a challenging task because often present low water-solubility, not very vibrant hues, and instability due interactions with ingredients. Chemometric approaches can be used evaluate color differences patterns resulting synthetic when applied systems. Here, the Mixture Design Principal Component Analys...

An efficient, sensitive and fast method was developed based on an ultrasound-assisted extraction followed by an ion-pair dispersive liquid-liquid microextraction (USAE-IP-DLLME) for the simultaneous determination of five commonly used synthetic sulfonate dyes (tartarazine, quinoline yellow, sunset yellow, azorubine, and brilliant blue) in ice cream samples using high performance liquid chromato...

ZnO- nanoparticles with an average particle size of 24 nm were successfully synthesized using the microwave assisted sol- gel technique. Structural and morphological properties of the nanoparticles were characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), Energy disperse spectrum (EDS) and Fourier transform infrared spectroscopy (FTIR). The band gap ene...

Background: Synthetic azo dyes are very extensively using various industries such as food items and non-food items. Tartrazine is well known dye due to its wide range of applications, also acid yellow 23. Most release these containing effluents into water bodies without proper treatment. There no well-documented study about the toxicological effect tartrazine in fishes. studies with concentrate...
