Examination of Pesticide Residues in Wine, Beer and Their Constituent Products Using High-Throughput Techniques to Maximize Extraction & Efficiency

There are hundreds of commercial pesticides in use in industrial and private agriculture. Concern over the health effects of residual pesticides on fruits and vegetables has led to increased testing of these products to determine the levels of pesticides
on produce when it goes to market.
In this study, commercial red wine and beer samples were examined for their pesticide concentrations. In addition to the examination of the finished alcoholic beverage, the constituent agriculture products of wine and beer production (grains, malts hops and wine grapes) were also examined to determine the levels of pesticides found in those products. The sample preparation and extraction process efficiency and recovery were examined by processing samples using manual versus high-throughput techniques. The QuEChERS method was used to process a greater number of samples in a shorter period of time than other extraction methods.
