摘要

Detection methods used in food safety can be classified into two categories: amplification and hybridization. Their purpose is to accumulate or to recognize target sequence specifically using a proper reaction buffer in vitro. Polymerase chain reaction (PCR) is a valuable tool for monitoring gene expression, for quantifying foodborne pathogens, and for use in clinical diagnostics. Hybridization methods offer a new frontier in the identification of targets in a simple and high-throughput way. This review mainly describes and compares the basic rules of PCR and hybridization, including their formatting source, characteristics, and applications.
