A Novel Method for Early Detection of Salmonella Contamination in Food Samples

总结

Purdue University researchers developed a product that won the grand prize in the 2014 FDA Food Safety Challenge - http://www.purdue.edu/newsroom/releases/2015/Q3/purdue-university-innovation-wins-fda-food-safety-challenge.html. This new product is a combination product of enzyme formulations and software for defining best conditions, using enzymes to treat food extracts. This product improves recovery of microorganisms and enhances rapid hollow tube microfiltration (in connection with a C3D instrument). It would allow matching enzymes to different food materials, identifying optimum conditions, and obtaining enhanced microbial recovery in order to analyze food microorganisms within four hours. This system would allow rapid concentration, retrieval, and discovery of pathogens that are present in various types of food. Due to the individual components of this technology, it has a 3- to 5-fold faster recovery of microorganisms, while concurrently minimizing the need for enrichment or selective culture that is usually used to obtain adequate cultures for pathogen detection.To view a video related to this technology, click this link: https://www.youtube.com/watch?v=pdJSDPnmIfs&feature=youtu.be.

*Abstract

*Background

To prevent food-borne pathogens from spreading and helping with safety and health of a population, it is essential to have pathogen detection systems. It is difficult to process food samples and there is a need to use different types of enzymes for this process. Current technologies for detection include culture enrichment and microfiltration, which are not as efficient, and none of these technologies supply enzyme solutions for enriching food extracts with respect to background microorganisms.
