Matthew Nosworthy, Ph.D.
Current research and/or projects
Dr. Nosworthy’s research has been focused on value-added processing of different plant crops including cereals and pulses, which aligns with the AAFC strategic area of “improving attributes for food and non-food uses”. Dr. Nosworthy’s work on plant protein quality ultimately assists in the further development of the plant-based product value chain through the quantification of nutritional quality and identification of bioactive compounds present in plant proteins.
Research and/or project statements
- Setting up a research lab to identify how variables, such as processing methods and genetic background influence the protein quality of plant-based products
- Establishing protocols for assessment of gastrointestinal protein digestion and its influence on the bioactivity of peptide fragments
Professional activities / interests
- Protein Quality Assessment
- Amino acid analysis
- Protein digestibility determination
- Bioactive peptides derived from plant proteins
- Value-added pulse ingredients and products
