Lili Mats, Ph.D.

Current research and/or projects

Dr. Mats works in a supporting capacity for many research scientists at GRDC and their collaborators. Modern HPLC-MS instrumentation helps to significantly enhance and accelerate analysis, and allows GRDC scientists to explore emerging fields of proteomics and metabolomics in their research. Her knowledge of metabolomics contributes to the understanding of phytochemical bioavailability, bioaccessibility and health attributes of functional foods and their byproducts. Use of HPLC-MS in characterization and quantification of bioactives in novel functional foods provides more healthy food choices, such as phenolic-rich pulses and anthocyanin-rich grains, to support healthy eating in Canada. Her work in enzymatic and bacterial detoxification helps reduce the risk of harmful food pathogens and promote safety of foods for Canadians. Dr. Mats’ expertise in food quality analysis helps develop new processing technologies and leads to industrial collaborations and partnerships.
