“…These methods are based on fluorescence (Brandao et al ., ; Durakli Velioglu et al ., ), flow injection mass spectroscopy (FIMS) (Du et al ., ), capillary electrophoresis (CE) (Trimboli et al ., ), laser‐induced breakdown spectroscopy (LIB) (Moncayo et al ., ), sensors (Sakti et al ., ; Gupta et al ., ), time‐domain nuclear magnetic resonance (TD‐NMR) (Santos et al ., ), enzyme‐linked immunosorbent assay (ELISA) (Pizzano & Salimei, ), polyacrylamide gel electrophoresis (Lee et al ., ; Pesic et al ., ), polymerase chain reaction (PCR) (Cheng et al ., ), high‐performance liquid chromatography‐based methods (Chen et al ., ; Ke et al ., ), electronic tongue (Dias et al ., ), FT‐NIRS (Mabood et al ., ,b), FT‐MIR (Nicolaou et al ., ; Jawaid et al ., ; Santos et al ., 2013a; Vieira et al ., ; Coitinho et al ., ) and infrared microspectroscopy (Santos et al ., 2013b). From all these available methods, infrared spectroscopy stands out more due to their test speed since a rapid answer is usually required as in the case of dairy industry (Cattaneo & Holroyd, ).…”
