AFFINIMIP® SPE Ochratoxin A

Specific extraction of Ochratoxin A from a variety of food samples matrices: cereals, wines, spices, coffee.

Ochratoxin (OTA) is a mycotoxin produced as a secondary metabolite of various Aspergillus and Penicillium fungis. It can be found on several commodities (e.g. cereals and cereal-based products, coffee, beer, grape juice, wine, cacao products).

Ochratoxin A exhibits toxicity in animals and mankind, including nephrotoxic, hepatotoxic, immunotoxic, teratogenic and carcinogenic effects and represents therefore a serious health risk to livestock and population. In order to limit these effects, European Regulation (EC) 1881/2006 sets maximum levels for Ochratoxin A in foodstuffs (e.g. 5μg/kg in raw cereal grains, 30μg/kg in spices).

AFFINIMIP® SPE Ochratoxin A are selective solid phase extraction cartridges that selectively clean and concentrate the toxin prior to analysis by HPLC.

Application notes

AFFINIMIP® SPE Cartridge VS ImmunoAffinity Column

Discover the advantages of AFFINISEP's Molecularly Imprinted Polymers over Immuno-affinity sorbents for mycotoxins analysis.

Cereals and spices

Ochratoxin A analysis has been carried out on Wheat and several spices (Paprika, grey Pepper). After cleanup and concentration with AFFINIMIP® SPE Ochratoxin A, recovery yields higher than 90% (concentration: 30µg/Kg) were obtained except for Grey Pepper (73% for a concentration of 5µg/Kg).

Application note AFFINIMIP® SPE Ochratoxin A Cereals and Spices

Red & white wines

Ochratoxin A concentrations in red and white wines were determined after pre-treatment with AFFINIMIP® SPE Ochratoxin A. High recovery yields were obtained via a very simple protocol.

Application note AFFINIMIP® SPE Ochratoxin A Red and White Wines

Automated protocol

The combination of AFFINIMIP® SPE Ochratoxin A SPE cartridges with an automate GILSON GX-271 ASPEC™ shows accurate and reliable analysis (CV 1.7% vs CV 2.5% in manual mode).
