Simultaneous Determination of Brilliant Blue FCF and Carmoisine in Food Samples by Aqueous Two-Phase System and Spectrophometric Detection
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 ...
متن کاملStructural determination of the subsidiary colors in food blue No. 1 (brilliant blue FCF) aluminum lake detected by paper chromatography.
One of eight Food Blue No. 1 aluminum lakes (B-1Als) used in the official inspection of coal-tar colors in fiscal year 1999 had a violet sub-spot during paper chromatography and was rejected. To clarify the orgin of the sub-spot, the violet subsidiary color (Sub-V) was isolated from the sample. On the basis of NMR and MS analyses and ion chromatography, the structure of the subsidiary color was...

متن کاملSiO2–TiO2 xerogels for tailoring the release of brilliant blue FCF
Xerogels consisting of SiO2 and TiO2 were explored for controlled release of brilliant blue FCF (BBF). Both SiO2 and SiO2–TiO2 xerogels were prepared by way of sol–gel processing, and the BBF release behavior was compared. SiO2–TiO2 xerogels with varying TiO2 content were also studied and the BBF release behavior was determined for each SiO2–TiO2 xerogel. It was found that the release of BBF fr...
