Research Scientist

To examine the bioactive components in cereal grains (barley, oat, wheat, and others) and pulses, and their impact on human health; to determine the effect of processing on functionality and health benefits of grain and pulse based foods. 

Current research and/or projects

Investigating the effect of pre-harvest glyphosate on quality of milling oats.

Evaluating the effect of processing methods, genotype and environment on the extractability of protein from oats and characterizing physiochemical and nutritional attributes of oat protein.

Investigating the effect of heat treatment on the storage stability, functional properties and sensory and microbial quality of food grade canaryseed groats and flours.

Determining levels of free asparagine (a precursor for acrylamide formation in baked foods) in Canadian Western Red Spring wheat varieties, and to identify effective mechanisms for its reduction.

Research and/or project statements

  • goal is to work in conjunction with breeders, researchers and the agri-food industry to develop improved cultivars and food processing techniques that maximize the health properties and utilization potential of Canadian grains and pulses
  • research experiments include:
    • quantification and characterization of fibre, phenolics and other compounds
    • pilot scale processing such as flaking, heat treatments and fractionation
    • functional food formulation for quality assessment and design of clinical trial test foods
    • development of in vitro methods for predicting and validating health outcomes.
  • Dr. Ames’ research program provides an important link between consumer health interests, industry development of value-added agricultural products, and genetic resources for Canadian-grown grains and pulses (fork to farm).
