Traditional extraction methods for food samples, such as liquid–liquid extraction (LLE) and Soxhlet extraction, are often time-consuming and require large amounts of organic solvents. Even with modern detection techniques, because of the low concentrations of contaminants and complicated food matrices, efficient sample preparation is necessary. As a result, reliable and efficient methods for food safety analyses are required. Such incidents have alerted the authorities and the public that more efforts and deeper investigations are needed. In general the public is increasingly concerned about the safety of the food products they consume every day as more and more food contamination incidents and widespread recalls arise. Therefore, one of the objectives of analytical food safety studies currently has been the development of new extraction techniques that can improve the accuracy and precision of analytical results and simplify the analytical procedure.įood safety has become a top concern in our society. Traditional extraction methods for food samples, such as liquid–liquid extraction and Soxhlet extraction, are often time consuming and require large amounts of organic solvents.
