Dr. Matthew Nosworthy received his Ph.D. in amino acid metabolism from the Department of Biochemistry at the Memorial University of Newfoundland in 2015, where he studied di-/tri-peptide transport in the Yucatan miniature piglet during growth and in states of disease. His three-year post-doctoral fellowship at the University of Manitoba from 2015-2018 investigated the effect of processing methods on in vivo and in vitro measures of plant protein quality.

Nosworthy then accepted a research associate position in the College of Pharmacy and Nutrition at the University of Saskatchewan. There he examined the relationship between genetic background and nutritional composition of pulse crops, how soil quality in Ethiopia alters crop nutrient content, and shelf-life and nutritional composition of extruded plant-based snacks. In April 2020, he accepted a Research Scientist position at the Guelph Research and Development Centre, Agriculture and Agri-food Canada, where he is currently investigating plant-based protein nutrition and metabolism.

Nosworthy’s research interests center on protein nutrition related to novel protein sources. This research includes the determination of amino acid composition and protein digestibility (protein nutritional quality). Other research areas include investigating the bioavailability of amino acids/peptides using in vivo and in vitro techniques and identifying bioactive properties present in proteins post-digestion and how they can benefit human health.

He has worked on diverse plant crops, including soy, pulses, canola, cereals, and hemp, at various stages of the food supply chain. To date, he has contributed to over 65 publications, book chapters, and conference abstracts in amino acid biochemistry and protein nutrition research.

2022 Protein Trends & Technologies Seminar

“Enabling Protein Claims & Improved Protein Quality Through Blending & Processing Protein Ingredients”

Interest in plant-based protein products has led to innovative consumer products whose success is aided by protein content marketing claims and Nutrition Facts panel information. In the U.S., the accuracy of these claims is regulated through the Protein Digestibility Corrected Amino Acid Score (PDCAAS), with plant-based proteins typically having lower PDCAAS scores than specific popular animal proteins. This presentation looks at how these limitations can be overcome through processing methodologies and blending complementary plant proteins. Additionally, information on how PDCCAS affects the percent daily value (%DV) of plant-based products, a current hot topic, will be provided.

“Increasing Plant-Based Products’ Protein Quality through Ingredient Blending”

Optimizing consumer interest in protein-enhanced products requires success in obtaining a protein content claim. In the U.S., this is regulated through a product’s Protein Digestibility Corrected Amino Acid Score (PDCAAS).  Plant-based proteins typically have lower PDCAAS scores than animal proteins due to reduced digestibility and amino acid compositions that are unable to satisfy human nutritional requirements. This presentation looks at how these limitations can be overcome through blending of complimentary plant proteins that can increase protein digestibility.
