“…Various methods for the determination of dyes in foods have been reported, including capillary electrophoresis [6][7][8][9][10], thinlayer chromatography [11], ion-pair chromatography [12,13], high performance liquid chromatography (HPLC) with ultraviolet/visible (UV/Vis) or diode-array detector (DAD) detection [14][15][16][17][18][19][20][21][22][23][24][25] and liquid chromatography-mass spectrometry (LC-MS) [26][27][28][29][30][31][32]. HPLC coupled with UV/Vis or DAD detection is the most commonly used technique because dyes absorb strongly at the ultraviolet and/or visible wavelength.…”

“…Embora a técnica de par-iônico seja a mais recomendada para a análise de corantes artificiais 9,16,21 , o uso desses compostos apresenta sempre o inconveniente de longos períodos de condicionamento.…”

“…A determinação de corantes sintéticos em alimentos tem sido feita por vários métodos espectrofotométricos 8 e cromatográficos, e mais recentemente utilizando a cromatografia líquida de alta eficiên-cia [9][10][11][12][13][14][15][16][17][18][19] . Prado e Godoy 1 desenvolveram e validaram uma metodologia, por CLAE que, além das vantagens de eficiência na separação, rapidez e simplicidade, permite a separação e quantificação dos oito corantes permitidos em uma única análise, utilizando sistema de eluição isocrática sem a adição de par-iônico à fase móvel.…”

“…For the purpose of quantification of the dye content in the pharmaceutical products and food, modern analytical methods and techniques are currently used, such as follows: high performance liquid chromatography (HPLC) [39,40,43,46,47,51,64,70,74], ion-pair liquid chromatography (IP-LC) [9,36], thin-layer chromatography (TLC) [5,49,63], spectrometry, derivative spectrometry, and spectrophotometric methods [7,57,62,68]. Electroanalytical methods also find its application in this field; mainly adsorptive voltammetry [1] and differential pulse polarography [8,12].…”
