Encapsulation and delivery of bioactive materials

Current research and/or projects

Food safety is one of the strategic objectives of Guelph Research and Development Centre. Withdrawal of antibiotics from animal feed is likely to increase the risk of bacterial infection in food animals, which may not only reduce production efficiency, but also increase pathogenic bacterial contamination of meat products. Therefore, development of antibiotic alternatives is an important measure of meat product safety. This research team has well-established expertise in developing new technologies for effectively delivering antibiotic alternatives into food animals. Inexpensively and effectively delivering is a critical step in the development of antibiotic alternatives in food animal production. This research team closely works with microbiologists in screening antibacterial components, with animal scientists to test the developed antibacterial products, and with engineers to scale up the developed technology.
