“…Methods of analysis in food Methods described in the literature for the detection of Brilliant Blue FCF are based on spectrophotometry (Vidotti et al, 2005;Li, 2008), HPLC (Kirschbaum andco-workers, 2003, Pereira Alves et al, 2008;Vachirapatama et al, 2008), ion chromatography (Chen et al, 1998), cathodic stripping voltametry (Florian et al, 2002) and capillary electrophoresis (Ishikawa et al, 2004). Li (2008) proposed a solid phase extraction followed by direct spectrophotometric determination of Brilliant Blue FCF in food samples. Kirschbaum and co-workers (2003) developed an HPLC-DAD method for the determination of permitted colorants including Brilliant Blue FCF.…”

Scientific Opinion on the re-evaluation of Brilliant Blue FCF (E 133) as a food additive

The Panel on Food Additives and Nutrient Sources added to Food provides a scientific opinion re‐evaluating the safety of Brilliant Blue FCF (E 133). Brilliant Blue FCF has been previously evaluated by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) in 1970 and the EU Scientific Committee for Food (SCF) in 1975. Both committees established an ADI of 12.5 mg/kg bw/day. In 1984, the SCF revised the ADI to 10 mg/kg bw/day, based on new long‐term studies. The Panel concluded that the present dataset on the absorption, distribution, metabolism and excretion, genotoxicity, subchronic, reproductive, developmental and long‐term toxicity, and carcinogenicity give reason to revise the ADI of 10 mg/kg bw/day allocated by the SCF in 1984. The Panel considered that the NOAEL of 631 mg/kg bw/day from the chronic toxicity study in rat can be used to allocate a new ADI to Brilliant Blue FCF. By application of an uncertainty factor of 100, the Panel established a new ADI to Brilliant Blue FCF equal to 6 mg/kg bw/day. The Panel concluded that at the maximum reported levels of use of Brilliant Blue FCF, refined intake estimates (Tier 3) are lower than the ADI of 6 mg/kg bw/day. The Panel concluded that at Tier 2 the intake estimates are below the ADI at the mean for both adults and children and at the higher level for adults, but above the ADI at the higher level (95th percentile) for children.

“…Among these methods, high performance liquid chromatography (HPLC) [23,24] has advantages of better resolution and fast, but needs complicated sample pretreatment process, but not suitable to analyze a large sum of samples. Spectrophotometry [25,26] is simple and fit for analyzing batch samples, but needs preconcentration technique. Electrochemiluminescence (ECL) [27] is also a sensor for brilliant blue analysis which has good chemical stability, wide pH range, high luminous efficiency, and excellent electrochemical performance, but the surface treatment of electrode is a little time-consuming and complicated.…”

Nitrogen-doped graphene quantum dots had been successfully synthesized and characterized by using transmission electron microscope, X-ray photoelectron spectroscopy, absorbance spectrum, fluorescence emission spectrum, and fluorescence decay curve. TEM results indicated that the diameters of the as-prepared nitrogen-doped graphene quantum dots were in the range of 2 - 5 nm and the lattice space is about 0.276 nm; Raman spectrum result indicated that there were two characteristic peaks, generally named D (~1408 cm−1) and G (~1640 cm−1) bands; both TEM and Raman spectrum results indicated that the as-synthesized product was graphene quantum dots. Deconvoluted high resolution XPS spectra for C1s, O1s, and N1s results indicated that there are -NH-, -COOH, and -OH groups on the surface of nitrogen-doped graphene quantum dot. Fluorescence emission spectrum indicated that the maximum fluorescence emission spectrum of nitrogen-doped graphene quantum dots was blue shift about 30.1 nm and the average fluorescence decay time of nitrogen-doped graphene quantum dots increased about 2 ns, compared with graphene quantum dots without doping of nitrogen. Then, the as-prepared nitrogen-doped graphene quantum dots were used to quantitatively analyze brilliant blue based on the fluorescent quenching of graphene quantum dots, and the effect of pH and reaction time on this fluorescent quenching system was also obtained. Under selected condition, the linear regression equations were F0/F=0.0087 (brilliant blue) + 0.9553 and F0/F=0.01205 (brilliant blue) + 0.6695, and low detection limit was 3.776 μmol/L (3.776 nmol/mL). Once more diluted N-GQDs (0.05 mg/mL) were used, the low detection limit could reach 94.87 nmol/L. Then, temperature-dependent experiment, absorbance spectra, and dynamic fluorescence quenching rate constant were used to study the quenching mechanism; all results indicated that this quenching process was a static quenching process based on the formation of complex between nitrogen-doped graphene quantum dots and brilliant blue through hydrogen bond. Particularly, this method was used to quantitatively analyze the wine sample, of which results have a high consistence with the results of the spectrophotometric method; demonstrating this fluorescence quenching method could be used in practical sample application.

Cyclodextrin is an odorless and tasteless cyclic oligosaccharide widely used in various fields such as food, medicine and the environment. Cyclodextrin can improve solubility and stability, and can mask the bad taste of specific substances. Cyclodextrins and their polymers primarily act by forming complexes in foods, and can be applied in food packing, food analysis, enhancing the properties of antioxidants, antibacterials, for stability and so on. The challenges and opportunities facing this area are reviewed. It is hoped that the review will provide useful information for future applications of cyclodextrin in the food industry.
