Fluorescence spectroscopy plays an important function in modern food analysis as can be seen from its wide use in the determination of numerous food components, contaminants, additives, and adulterants. This technique has made available very sensitive and selective methods that satisfy the requirements of food analysis, which are usually very complex, taking into account the large number of species to be determined, frequently at very low concentrations, and the wide variety of foodstuffs available. Initially, the use of fluorescence spectroscopy in food analysis was limited to the determination of species with intrinsic fluorescence (e.g., vitamins, aflatoxins, and some polycyclic aromatic hydrocarbons (PAHs)), but now it is widely applied to nonfluorescent species, using several physicochemical means such as chemical or photochemical derivatization reactions. Numerous techniques involve fluorescence detection in liquid chromatography (LC), frequently using pre- or postcolumn derivatization. In addition to conventional fluorime-try, which is commonly chosen for this purpose, other fluorimetric techniques such as laser-induced... [Pg.1425]

These dyes are used as biological stains and, except for Rose Bengal, as color additives permitted for coloring food (FD C Red No. 3), drugs, and cosmetics in the United States. Standard pH-zone-refining CCC was also applied to the separation of contaminants from these colors and their intermediates. The purified contaminants were then used as reference materials in the development of analytical methods [high-performance liquid chromatography... [Pg.2268]

Liquid chromatography-time-of-fiight (TOF)-mass spectrometry has also been established as a valuable technique for the routine control of the wholesomeness of food. In this sense, TOF techniques can record an accurate full-scan spectrum throughout the acquisition range and have resulted as an excellent tool for the unequivocal target and nontarget identification and confirmation of food contaminants [105,106].

Due to its high sensitivity and selectivity, liquid chromatography-mass spectrometry (LC-MS) is a powerful technique. It is used for various applications, often involving the detection and identification of chemicals in a complex mixture. Ultra Performance Liquid Chromatography Mass Spectrometry Evaluation and Applications in Food Analysis presents a unique collection of up-to-date UPLC-MS/MS methods for the separation and quantitative determination of components, contaminants, vitamins, and aroma and flavor compounds in a wide variety of foods and food products.
