                                    Citation: Appell, M., Jackson, M.A. 2013. Adsorption of mycotoxins in beverages onto functionalized mesoporous silicas. American Chemical Society National Meeting. Abstract.Interpretive Summary:
                                Technical Abstract: Mycotoxins, natural toxins produced by fungi, are a global concern as contaminates of agricultural commodities. Exposure to these toxins can be reduced by the use of binding materials. Templated mesoporous silicas are promising materials with favorable adsorptive properties for dyes, ions, and toxins. Silicas MCM-41, SBA-15, and HMS were investigated for their ability to sequester structurally diverse mycotoxins ochratoxin A, zearalenone, and patulin. Equilibrium binding assays were carried out in water and fruit-based drinks, and toxin levels were measured using high-performance liquid chromatography (HPLC). The propylthiol and propylamine functionalized silicas prepared by co-condensation improved mycotoxin binding compared to non-functionalized mesoporous silicas. The ordered channels of the mesoporous silicas offered high binding capacity and the potential for incorporation of functional groups to tune and improve molecular recognition.
