An Automated Method for the Selective Solid Phase Extraction of Zearalenone from Wheat Using Molecularly Imprinted Polymers
2 Nov 2017Zearalenone [6-(10-hydroxy-6-oxo-trans-1-undecenyl)-ß-resorcyclic acid lactone] is a mycotoxin produced as a secondary metabolite of various Fusarium fungi, and has been detected in a variety of cereal products such as wheat, maize, barley, oats, rice and sorghum as well as beer that has been produced with contaminated grains. This study describes the automated solid phase extraction (SPE) of ZON from wheat using a Molecularly Imprinted Polymer (MIP) SPE cartridge that is highly specific for Zearalenone and the Gilson GX-271 ASPEC™.

Solid-Phase ExtractionSolid-phase extraction (SPE) is used for clean-up, extraction and concentration of semi-volatile or non-volatile analytes from complex mixtures including blood, urine and food samples. Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats.

In humid conditions, fungi can proliferate and colonize on crops to levels that can be damaging to human health. Food TestingFood testing refers to a variety experiments including PCR, mass spectrometry, processing, QuEChERS, analyzing and Kjeldahl.PolymersPolymers are large molecules made up of many repeat units. Natural polymers such as DNA and proteins are essential to life, whereas synthetic polymers such as polystyrene and polyethylene are used widely due to their functionality. Typical techniques for analysis include GPC, SEC, DSC, FT-IR and NMR.Food ContaminationFood contamination refers to the presence of harmful substances or pathogens in food, posing risks to human health. Contaminants can be biological, chemical, or physical, and their detection is crucial for ensuring food safety. Advanced testing methods like PCR, chromatography, and spectroscopy are used to identify contaminants in food products.
