Fast and selective analytical procedures for determination of persistent organic pollutants in food and feed using recent extraction techniques

By CS Eskilsson, Sune Sporring and Erland Björklund

Abstract

This chapter describes the utilization of recent extraction techniques such as supercritical fluid extraction, pressurized liquid extraction and microwave-assisted extraction for the determination of persistent organic pollutants in food and feed samples. These techniques have been developed because the extraction step can severely limit the entire analytical procedure. Several food crises, for example dioxins entering the food chain, have stressed the requirement for high sample throughput. Increased sample throughput can be obtained by using automated clean-up systems following the extraction process; however, these techniques are often very costly. This text aims at describing how a substantial decrease in the time spent on sample handling can be achieved with for example integrated clean-up strategies
