Researchers at the University of California, Davis have developed an antimicrobial particle with the ability to bind bacteria and biofilm.
Contamination can occur thought the entire food production process, starting at production through processing, distribution and preparation. Washing food (including produce) with water can still leave behind bacteria and microbes on the surface. Current chemical treatments, such as chlorine in wash water, reduce the amount of microbes and bacteria but more efficient cleaning methods could improve both food safety and shelf life.
Researchers at the University of California, Davis have developed a sanitation method that uses surface bound chlorine-particles for the treatment of fresh produce, raw meat and food contact surfaces. The particles can be used thought the food production process - on the soil during food production to any food contact surfaces in processing, distribution and preparation. The designed particles can carry a variety of antimicrobial agents to bind specific and diverse bacteria and biofilms. In tests completed by the researchers, a concentration of 2 mg/ml of this sanitizer led to a greater than 5 log reduction in both pathogenic and spoilage microbes. Chlorine in wash water only produced a 2 log reduction. These particles can substantially decrease the costs associated with sanitation products and increase the speed of sanitation processes.
