Research Progress of Compound Techniques for Enrichment and Detection of Foodborne Pathogens

Foodborne pathogen poses a threat to food safety and human health.The low concentrations pathogens in food can only be detected by pretreatment combined with effective detection techniques.The rapid detection methods are affected by the composition of the enrichment solution, food components, or low cell concentration, so it is necessary to separate and enrich the pathogenic bacteria from the samples in order to shorten the detection time and carry out accurate detection.In this paper, enrichment methods for pathogenic bacteria were analyzed, including bare magnetic beads and functional magnetic beads. Moreover, the integrated methods of enrichment and detection were reviewed, including electrophoresis technology, microfluidic technology and so on.For the enrichment of specific pathogenic bacteria, it is necessary to further improve the adsorption rate and sensitivity.It is continuously improved in detection sensitivity and detection limit for the completed technology of enrichment and detection.
