“…Appell et al indicated that cyclodextrin‐functionalized polymers could bind with patulin through noncovalent interaction . Anene et al developed a molecularly imprinted polymer material to capture patulin through selective cavity . But these weak interactions were easy to cause patulin escaping, so some researchers further fabricated thiol‐modified material to remove patulin through Michael addition reaction between patulin and thiol groups .…”

Membrane AdsorberMussel-inspired membrane adsorber with thiol ligand (SH-membrane adsorber) is prepared by polydopamine-assisted poly(ethylene imine) grafting and subsequent thiolation modification for efficient removal of patulin. The effects of temperature, contact time, pH, and initial patulin concentration on the adsorption capacity of the membrane adsorber are investigated. The results show that the SH-membrane adsorber is effective to remove patulin. The adsorption capacity of the membrane can reach 1245.11 µg g −1 for patulin. In static adsorption tests, the adsorption kinetic and equilibrium data are well fitted by the pseudo-second-order kinetic model and Freundlich isotherm model, respectively, meaning that the adsorption process is a multilayer chemical adsorption. The SH-membrane adsorber can be recovered by l-cysteine, and the removal efficiency of patulin is maintained at about 89.23% after eight reuse cycles, compared to the 17.33% of control membrane. These results demonstrate that the SH-membrane adsorber has a potential application for patulin removal.

“…In contrast, other authors have developed more selective strategies to achieve the extraction of patulin through the preparation of MIP materials [50,51]. In this sense, Anene et al developed a MIP sorbent by bulk polymerization using patulin as template [50]. The material was used in SPE for the extraction of patulin from apple and juice samples prior to its determination by HPLC-DAD analysis.…”

“…Accordingly, Zhao et al prepared a dummy MIP by precipitation polymerization for the extraction of patulin using 2-oxindole and 6-hydroxynicotinic acid as dual-dummy template molecules [51]. In this case, with a smaller amount of sorbent (30 mg) than the previous work [50], it was possible to successfully extract patulin obtaining high recovery values (81-106%). Moreover, the extraction efficiency of the method proposed with the dummy MIP was compared with the QuEChERS method, showing better purification effect and higher recovery of patulin.…”

New Advanced Materials and Sorbent-Based Microextraction Techniques as Strategies in Sample Preparation to Improve the Determination of Natural Toxins in Food Samples

Natural toxins are chemical substances that are not toxic to the organisms that produce them, but which can be a potential risk to human health when ingested through food. Thus, it is of high interest to develop advanced analytical methodologies to control the occurrence of these compounds in food products. However, the analysis of food samples is a challenging task because of the high complexity of these matrices, which hinders the extraction and detection of the analytes. Therefore, sample preparation is a crucial step in food analysis to achieve adequate isolation and/or preconcentration of analytes and provide suitable clean-up of matrix interferences prior to instrumental analysis. Current trends in sample preparation involve moving towards “greener” approaches by scaling down analytical operations, miniaturizing the instruments and integrating new advanced materials as sorbents. The combination of these new materials with sorbent-based microextraction technologies enables the development of high-throughput sample preparation methods, which improve conventional extraction and clean-up procedures. This review gives an overview of the most relevant analytical strategies employed for sorbent-based microextraction of natural toxins of exogenous origin from food, as well as the improvements achieved in food sample preparation by the integration of new advanced materials as sorbents in these microextraction techniques, giving some relevant examples from the last ten years. Challenges and expected future trends are also discussed.

The aim of the present study was to develop new molecularly imprinted polymers (MIPs) to coat stainless steel plates for the removal of aflatoxin M 1 (AFM 1 ), which is a serious concern in the safety of milk and dairy products. Scanning electron microscopy, energy dispersive spectroscopy, and Fourier-transform infrared spectroscopy tests confirmed that MIPs successfully coated the stainless steel plates. The MIPs were applied to extract AFM 1 from milk spiked with 0.5 to 50 ng/ mL AFM 1 . The MIPs removed 87.3-96.2% of the AFM 1 without any notable effects on the milk composition. The results also showed that the imprinting factors of DMC, AFM 1 , AFB 1, and AFG 1 were 5.93, 4.61, 3.41, and 2.72, respectively.
