Dr. Nuria Prieto

Research Scientist - Meat Quality and Sensory Chemometrics

Dr. Nuria Prieto conducts research to assist the Canadian meat industry with their current vision of determining points of product differentiation, without additional costs for packers and retailers, as a strategy towards increasing national and international competitiveness. The major objectives of Dr. Prieto’s Meat Quality and Sensory Chemometrics program are focused on differentiation of meat and meat products based on quality and sensory attributes, implementation of strategies to produce value-added meat from agriculturally important livestock species, address of meat palatability issues including understanding and control of flavour through technological advances in meat chemistry and chemometrics, and evaluation of non-invasive technologies for rapid assessment of meat quality attributes.

Current research and/or projects

  • Benchmarking Canadian retail beef flavour.
  • Canada's National Beef Quality Audit at Retail and Processing.
  • Alberta Beef Flavour: Utilizing flavour chemistry and sensory methods towards determining the uniqueness of Alberta beef flavour.
  • Novel analytical methods for meat flavour fingerprinting.
  • Classifying Canadian pork based on quality attributes.

Research and/or project statements

  • Generate new knowledge of attributes that differentiate Canadian meat and meat products, while meeting quality and cost requirements, to improve the profitability and competitiveness of the agri-food sector.
  • Improve key meat quality attributes from agriculturally important livestock species.
  • Enhancement of meat palatability, including flavour fingerprinting to identify volatile compounds that allow the rapid and anticipated identification of products with potentially desirable flavours, as well as their monitoring and marketing to target populations.
  • Market-driven quality assessment technologies: development and implementation of new high-throughput technologies for meat quality evaluation.
