Application of Omics and Related Tools for the Analysis of Food Authenticity
The Virtual Seminar Series on Food Authenticity is organized by researchers and students at 91社区 and the University of Guelph.
Food fraud, an issue causing a $65 billion USD damage/year to the industry, happens when there are discrepancies between the labeling information and the real food in the package, and the discrepancies are caused by intentional practices for extra economic benefits. Effective prevention strategies are needed to protect all the stakeholders from economic loss, trust crisis and potential health damage (e.g., allergen, toxic adulterants). Among the different approaches, analytical tools that can identify fraudulent food products serve as the last barrier to prevent those products from contaminating the supply chain. Involving complex sample matrices, analytical tools for food authenticity analysis need to be sensitive and have a high resolution. Omics tools, originally developed to analyze collection(s) of chemicals in biological samples, have attracted attentions of food researchers due to their excellent performance in analyzing complex sample matrices. My presentat ion will focus on the omics-related tools that we have developed and applied to analyze food authenticity and safeguard the overall food integrity.
