Determination of additives in food by capillary electrophoresis

Abstract: The application of capillary electrophoresis (CE) to the analysis of additives in food has been reviewed. Additives included in the review are preservatives, antioxidants, sweeteners, colourings, caffeine, niacin, choline, nitrate, and nitrite. The review highlights the versatility of CE in separating this often widely disparate group of compounds. The application of the methods to real food samples is also discussed.

“…This last characteristic is the main advantage versus chromatographic methods, which makes CE useful for routine analysis as well as for controlling and monitoring processes in a number of industrial fields [205][206][207][208][209][210][211][212][213]. Moreover, CE is relatively well suited to analysis of samples with complex matrices, like VOO.…”

“…Esses métodos incluem desde a detecção qualitativa através de reações colorimétricas até métodos semiquantitativos e quantitativos, como espectrofotometria, voltametria, polarografia e métodos cromatográficos, tais como cromatografia em camada delgada -CCD, 9,10 de permeação em gel -CPG, 11 em fase gasosa -CG, 12-15 líquida de alta eficiência -CLAE [16][17][18][19][20][21][22] e eletroforese capilar -CE. 23 Dos métodos citados, CG e CLAE são os mais empregados para a separação e quantificação dos antioxidantes sintéticos.…”

“…[26][27][28][29] Métodos para a separação de antioxidantes em fase normal têm sido propostos por Van Niekerk e Du Plessis, 30 Indik e Woollard, 31 Anderson e Van Niekerk, 26 mas são pouco empregados, já que a utilização de fase normal apresenta a desvantagem de necessitar de misturas complexas de solventes para a fase móvel, que são tóxicos tais como dioxano-hexano, 30 hexano-cloreto de metileno-acetonitrila 31 e hexano-1,4-dioxano-acetonitrila, 22 enquanto que a fase reversa emprega solventes mais comuns como o metanol e acetonitrila e, portanto, tem a preferência dos pesquisadores. [17][18][19][20][21][22][23]27,[32][33][34] No Brasil, quase não existem dados sobre os níveis reais de antioxidantes presentes nos alimentos. Portanto, é de fundamental importância desenvolver um método analítico que seja adequado para a determinação simultânea dos antioxidantes sintéticos permitidos pela legislação brasileira.…”

“…In China, the allowance of AR used in drinks is 0.1 g kg -1 . 6 In recent years, much work has been done to develop various techniques, including voltammetry, 7,8 differential pulse polarography, [9][10][11] liquid chromato graphy or liquid chromato graphy/ mass spectrometry, [12][13][14][15][16][17] spectrophotometry, [18][19][20][21][22] capillary electrophoresis, [23][24][25] to determine AR. Both voltammetry and differential pulse polarography can determine AR quickly and easily, but they are can not be applied to determine mixed food color additives in the food and beverages.…”
