Abstract: Quality control constitutes a major challenge in food security and human health protection. Recent advances in sample preparation techniques, such as extraction, concentration, and separation have led to an accurate monitoring of hazardous compounds in food. Among these techniques, solid phase extraction (SPE) is rapidly developing by providing innovative materials such as molecular recognition sorbents. The performance of these selective tools is majorly influenced by the affinity receptor used to bind the target. As an alternative to enzymes and antibodies, bio-inspired recognition elements have attracted much attention in recent years. The main advantage of these molecules is their simple and low cost production. They are chemically synthesized and based on inorganic matrices (molecularly imprinted polymers), nucleic acids (aptamers), or polypeptides. Characterized by high stability, selectivity, and affinity, artificial receptors have been widely investigated in the purification and detection of food contaminants. We focus in this chapter on the use of MIPs and aptamers in food sample preparation, in particular on their application in solid phase extraction
