"Improved Detection Techniques for Foodborne Pathogens: Separation Techniques Using Crossflow Microfiltration"

 

Separating and concentrating microorganisms in foods have been suggested as an alternative to enrichment culture as a pre-analytical step of detection in accordance with the need of a truly real-time technique for foodborne pathogen detection. Direct concentrating and recovering cells from food matrices is difficult due to the heterogeneous nature of foods and there is a lack of method to cope with this difficulty. As a remedy to this problem, this work proposed a new protocol which includes sampling from food by homogenizing, enzymatic pretreatment of crude food homogenates, pre-filtration, and cell concentration and recovery using a cell concentration instrument. The principle of instrument is to process the food samples by microfiltration in a cross-flow mode to concentrate the sample to a small volume, increasing the concentration of microbial cells to a detectable level so that they may be effectively probed for the presence of pathogens. In addition, a mathematical model is developed to clarify the fouling process and to provide insight into the optimization of membrane design, operational conditions and cleaning procedures.
