Interference-free determination of illegal dyes in sauces and condiments by matrix solid phase dispersion (MSPD) and liquid chromatography (HPLC–DAD)

Analysis of Sudan I in Food by QuEChERS Combined with Ultrasound-assisted Dispersive Liquid-liquid Microextraction with Solidification of Floating Organic Drop (UADLLME-SFO) Prior to HPLC-PAD

“…Enríquez-Gabeiras et al, 2012;He et al, 2007, Lopez-Jimenez et al, 2010Qi et al, 2011). Seen from Tab.…”

“…Sudan I has been detected in many food products, such as spices, sausage and egg, which was maliciously added to boost up the typical reddish color of products (Oplatowska et al, 2011;Enríquez-Gabeiras et al, 2012;Hu et al, 2012;Elyasi et al, 2013). It is reported that Sudan I is a possible carcinogen and mutagen to human (Moller and Wallin, 2002;Stiborova et al, 2002).…”

“…Currently, the methods involving in detecting Sudan dyes in food samples are mainly high-performance liquid chromatography (HPLC) coupled with UV/vis or MS detection (Enríquez-Gabeiras et al, 2012;He et al, 2007;Qi et al, 2011;Yu et al, 2008;Zhu et al, 2014). To avoid the expensive MS dectector, some sample pretreatment procedures are necessary for complex food matrices.…”

“…Solid-phase extraction (SPE), solid-phase microextraction (SPME), molecularly imprinted matrix solid-phase dispersion, molecularly imprinted solid-phase extraction combined with ultrasound-assisted dispersive liquid-liquid microextraction and gel permeation chromatography, have been applied to clean-up procedure the food samples before Sudan I detection (Qi et al, 2011;Enríquez-Gabeiras et al, 2012;Xin et al, 2011;Yan et al, 2011;Hu et al, 2012). But there are disadvantages involving in these methods such as time-consuming, expensive, costing large amounts of organic solvents and producing large amounts of organic waste.…”

Rapid Method for Quantification of Seven Synthetic Pigments in Colored Chinese Steamed Buns Using UFLC-MS/MS without SPE

“…Some analytical methods based on high performance liquid chromatography (HPLC) for synthetic colorants have been proposed, such as HPLC with ultraviolet/visible (UV/Vis) or diode-array detectors (DAD), [5][6][7][8][9] and liquid chromatography-mass spectrometry (LC-MS). 2,10,11 Mass spectrometry (MS) detectors are becoming the most commonly used methods for detecting synthetic pigment residue.…”
