A whole-column detection (WCD) system was fabricated using the parts from a typical A4 size optical scanner. Optimum layout of the fluorescence tube, beam condenser and photon transducers from the scanner made an effective devise to examine the dynamic chromatographic separation process. This system was applied in monitoring peak crossover in an ion-pair chromatographic elution. A stage-wise gr...
Saeed S. M.G., Abdullah S.U., Sayeed S.A., Ali R. (2010): Food protein: Food colour interactions and its application in rapid protein assay. Czech J. Food Sci., 28: 506–513. The uniform distribution of colours as additives in a majority of the food systems is a reliable indication that one or more components of foods are able to bind with colour molecules and act as their carriers. However, the...
Purpose. Investigate the formation and functioning of symbiotic systems soybeans with nodule bacteria by inoculation seeds biological products based on fungicide-resistant strains Bradyrhizobium japonicum PC07 B78 different rates synthetic carmoisine colorant. Methods. Physiological, microbiological, gas chromatography, statistical. Results. It was found that as a result inoculation soybean [G...
Four simple, rapid, and accurate spectrophotometric methods were developed for the simultaneous determination of two food colorants, Carmoisine (E122) and Ponceau 4R (E124), in their binary mixtures and soft drinks. The first method is based on recording the first derivative curves and determining each component using the zero-crossing technique. The second method uses the first derivative of r...
Direct selective detection of erythrosine in saffron in the presence of other synthetic dyes considers its fluorescence at 532 nm excitation/548 nm emission. Saffron pre-treatment was according to the ISO 3632-2 trade standard test methods. On account of calculated quantum yield values, none of the yellow dyes is expected to interfere. Among red ones, reservations about allura red AC, azorubine...
A novel, simple and more sensitive spectrophotometric procedure has been developed for the determination of Brilliant blue FCF and Carmoisine in food samples by an aqueous two-phase system (ATPS). After extraction, the absorbance values were measured at 527 and 632 nm for Carmoisine and Brilliant blue FCF, respectively. The effects of different parameters such as, polyethylene glycol (type and ...
The question of whether food additives such as preservatives, artificial flavorings, and artificial colorings trigger hyperactivity has been debated for more than 30 years. Research generally has not supported food additives as influencing hyperactivity—whose characteristics include overactivity, inattention, and impulsive behaviors, traits that in extreme forms define attention deficit/hyperac...
Natural and chemical colorants are attracting a lot of attention as sustainable feed additives due to their effect on food color because presentation matters consumers. Color also is major sensory factor that helps consumers determine quality its possible health benefits. For example, highly colored egg yolks can only come from healthy laying hens fed well-balanced, nutrient-rich diet. Consumer...
