Posted by Alternariol (AOH) is a mycotoxin which occurs in wine and tomato products as contaminant. Cyclodextrins (CDs) are ring-shaped glucose oligomers. Insoluble β-CD bead polymer (BBP) crosslinked with epichlorohydrin almost completely removed AOH from aqueous solutions (pH 3.0–7.4). BBP was used to extract AOH from spiked wine and tomato juice samples, during which the quality of beverages was also monitored. BBP strongly decreased the AOH content of both wine and tomato juice samples, suggesting the potential suitability of CD polymers as AOH binders in some beverages.
After AOH binding, BBP was successfully regenerated with 50 v/v% ethanol-water mixture.
