Abused or misused carbadox (CBX) and cyadox (CYA) in animal feed may cause food safety concerns, threatening human health. Here, we describe the design of a novel hapten for preparation of a monoclonal antibody against CBX and CYA simultaneously. Using this antibody, colloidal gold immunochromatographic assay (GICA) was developed for screening of CBX and CYA residues in chicken breast. Under optimal conditions, semiquantitative analysis results were visible by eye, with a visual limit of detection of 8 μg/kg for CBX and CYA, and cut-off values of 20 μg/kg for CBX and 40 μg/kg for CYA in chicken breast. Quantitative analysis could be performed using a hand-held strip scanner, with a calculated limit of detection of 2.92 μg/kg for CBX and 2.68 μg/kg for CYA in chicken breast. Validated by liquid chromatography−MS/MS, the developed GICA provides a useful tool for rapid on-site CBX and CYA residue screening in chicken breast.

“…MEPS can be combined with LC to analyze different complex samples but in view of the technical facilities to use liquid samples the majority of works in the literature report samples such as beverages, waters, urine, blood, and plasma . Recently in the food field, this technique has been more used in the analysis of wines, milk, tea, juices, and others alcoholic beverages .…”

“…The determination of quinolones in milk samples was investigated by Zhang et al. that developed a selective and sensitive method applying an immunoaffinity sorbent (IA) in microextraction by packed sorbent with subsequent determination by HPLC‐FLD. A validation step was carried out reporting a linearity in the range of 0.1–100 ng/mL with LODs and LOQs between 0.05–0.10 and 0.15–0.3 ng/g, respectively.…”

Recent trends in sorption‐based sample preparation and liquid chromatography techniques for food analysis

The accelerated rising of the world's population increased the consumption of food, thus demanding more rigors in the control of residue and contaminants in food-based products marketed for human consumption. In view of the complexity of most food matrices, including fruits, vegetables, different types of meat, beverages, among others, a sample preparation step is important to provide more reliable results when combined with HPLC separations. An adequate sample preparation step before the chromatographic analysis is mandatory in obtaining higher precision and accuracy in order to improve the extraction of the target analytes, one of the priorities in analytical chemistry. The recent discovery of new materials such as ionic liquids, graphene-derived materials, molecularly imprinted polymers, restricted access media, magnetic nanoparticles, and carbonaceous nanomaterials, provided high sensitivity and selectivity results in an extensive variety of applications. These materials, as well as their several possible combinations, have been demonstrated to be highly appropriate for the extraction of different analytes in complex samples such as food products. The main characteristics and application of these new materials in food analysis will be presented and discussed in this paper. Another topic discussed in this review covers the main advantages and limitations of sample preparation microtechniques, as well as their off-line and on-line combination with HPLC for food analysis.

“…In this scenario, even if MEPS is more easily automated than SPE, and more robust than solid-phase microextraction (SPME) [13], sorbent-based techniques and their different formats certainly represent a valid choice. These techniques provide simplicity in their operation, consume no solvent or minimize solvent usage, allow the separation and pre-concentration of the analytes using different commercial fibers, and the possibility of automating the entire process could be successfully applied in food, environmental, clinical, pharmaceutical and bioanalysis applications [14][15][16], as recently reviewed by Silva and co-workers [17].…”
