Posted by In previous studies, the extraction of mycotoxins alternariol, zearalenone, zearalenols, zearalenone-14-glucoside, and zearalenone-14-sulfate from aqueous solutions (including certain beverages) by beta-cyclodextrin bead polymer (BBP) has been demonstrated [1-5]. In a recent investigation, BBP-induced removal was also tested regarding further 12 mycotoxins, including aflatoxin B1, aflatoxin M1, citrinin, dihydrocitrinone, cyclopiazonic acid, deoxynivalenol, ochratoxin A, patulin, sterigmatocystin, zearalanone, α-zearalanol, and β-zearalanol [6]. BBP was a weak binder of deoxynivalenol, aflatoxin M1, and patulin, it was a moderate binder of aflatoxin B1 and cyclopiazonic acid, while BBP proved to be a strong binder of citrinin, dihydrocitrinone, sterigmatocystin, zearalanone, α-zearalanol, and β-zearalanol. The environmental pH (tested between pH 3.0 and pH 7.0) has no strong effect on the mycotoxin binding ability of BBP, except ochratoxin A which was extracted effectively only at pH 3.0. This study underline that BBP may be suitable for mycotoxin removal/extraction e.g. for decontamination and/or for analytical purposes.
