Research Scientist

Food Science and Nutrition

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
