Abstract

The applicability of an ELISA for detection and quantification of benalaxyl in red wine samples is described. The study of the influence of this matrix on the reliability of the assay indicates that red wine samples require a rapid and simple cleanup step before ELISA assay. Recovery and precision of the method were evaluated by spiking red wine samples with benalaxyl in the 0.5-24 ng/mL range. Benalaxyl can be determined with good accuracy and precision up to 0.5 ng/mL in starting red wine samples (detection limit of 0.13 ng/mL). No false negative or positive results were obtained. Authentic red wine samples were analyzed by ELISA and by RP-HPLC. The amounts of benalaxyl found by ELISA were in good agreement with RP-HPLC analysis
