Colour, a vital constituent of food, is indispensable to the modern day consumer as a means for the rapid identification and ultimate acceptance of food. A number of reviews concerning the toxicology of natural and synthetic dyes, especially those used in food, have appeared since the dyestuffs became potential suspects for causing cancer. A large number of natural or synthetic dyes have been r...

the electrocoagulation (ec) is a simple and efficient method for the treatment of many water and wastewaters.the kinetics of decolorization of acid yellow 23 by ec using iron electrodes was studied. theelectrodecolorization rate follows pseudo-first order kinetic with respect to the ay23 concentration havingkapp= 5.65 cm min-1 at t= 295 k. the rate equation is as follows:ln [ay23]t – ln [ay23]0...

A simple spectrophotometric method is described for resolving binary mixtures of some food dyes: Amaranth, Brilliant Blue, Sunset Yellow and Tartrazine, using the first-derivative spectra with measurements at zero-crossing wavelengths. Analytical curves are linear up to 20 mg L(-1). Standard deviations of 1.30, 2.22, 1.93 and 0.81% were obtained for synthetic binary mixtures of 2 mg L(-1) of Am...

An exposure assessment of synthetic food colours was carried out among 1-5- and 6-18-year-old individuals by the food frequency method. Children had an intake of solid food consumption in the range 2-465 g day(-1) and liquid food consumption in the range 25-840 ml day(-1) with added colours. Among the eight permitted colours in India, six were consumed by the subjects of the study. The intakes ...

We reported the simultaneous decolorization of tartrazine and H2 production via electrocoagulation photocatalysis using CuO-doped TiO2 nanotube arrays (TNTA) composites. Tartrazine was removed by combination adsorption, electrocoagulation, photocatalytic degradation, while produced through water reduction at cathode splitting process on photocatalyst surface. The photoreactor contains CuO-TNTA ...

Virtual stain transfer is a promising area of research in Computational Pathology, which has great potential to alleviate important limitations when applying deep-learning-based solutions such as lack annotations and sensitivity domain shift. However, the literature, majority virtual staining approaches are trained for specific or combination, their extension unseen stainings requires acquisiti...
