The Department of Food and Bioproduct Sciences provides the agri-food and bioresources industries with highly trained graduates and innovative research solutions for exploiting existing and emerging opportunities for the agriculture sector. Our interdisciplinary teaching approach provides Canadian and International students with the advanced knowledge and understanding of agricultural outputs and by- and co-products (proteins, carbohydrates/fibre and lipids), processing, genetic engineering and microbial biotechnology that can be then tailored to the areas of food science and technology, biomaterials, biotechnology bio-energy and nutrigenomics.
Our researchers are at the forefront of food and bioproducts research in Canada, and are recognized internationally for their specialties in food for health, food chemistry, processing, microbial biotechnology, authenticity, nanotechnology, meat science, bio-energy and nutrigenomics.
With our faculty complement filling strategic target areas within the area of food and bioproducts, undergraduate and graduate students have access to one of the best interdisciplinary educational and research opportunities offered from a research-intensive university in Canada. Our department provides a research continuum by traditional agriculture sciences to value-added industrial technologies.
Our commitment to our undergraduate and graduate students is reflected by the diversity of our student enrolment, as we welcome young scientists from across Saskatchewan, Canada and from around the globe into our programs. Within this multicultural and interdisciplinary environment, students are given the skills and knowledge to become 'market-ready' upon graduation; immediately impacting their user community. Our faculty and staff are strongly committed to educating the next scientific leaders in the area of food and bioproducts.
We offer two bachelor degree programs: one is hosted in the College of Agriculture and Bioresources (BSA in Food Bioproduct Sciences) and the other is offered through the College of Arts and Sciences (B.Sc. in Food Science).
Saskatchewan is well known as the "bread basket of Canada", although "bread basket" today does not mean we only produce primary agricultural commodities. Advances in agro-biological science and biotechnology extend the scope of the agriculture to food and bioproducts. Historically, our department has two streams of research, food science and applied microbiology, both of which involve the application of science and technology in pre- and post-harvest agriculture and in adding "value" to our primary agriproducts. In recent years, the boundary between the two steams has become vague, which has pushed our research frontier beyond traditional food and microbial products. Our goal is to fully utilize renewable bioresources to produce healthy foods and environmentally friendly bioproducts to support a sustainable bioeconomy.
Our department has a wide breath of expertise in food and bioproduct sciences. Faculty interests range from functional genomics and systems biology to processing technologies and physicochemistry applied to create novel food and bioproducts.

This research program is directed towards enzyme utilization in the food and bioproduct processing. In the fermented foods, proteolysis contributes changes in characteristics of foods, such as flavour, texture, nutrient values. Moreover, recent research revealed that many resultant peptides of the proteolysis, also known as bioactive peptides, have biological activities in favour of human health. On top of it, final products of proteolysis, amino acids, often promote human health through allowing rapid assimilation. In this research, the enzymes involved in the proteolysis in fermented foods are investigated in order to produce novel food products.
Biofuel is a booming commodity among agroproducts. Both biofuels, bioethanol and biodiesel, share a major byproduct, glycerol, that has been used as a stabilizer in foods and cosmetics. The demands for glycerol, unfortunately, do not match the growth of biofuel productions. As a result, it is critical to find methods to efficiently use glycerol for new applications. This research investigates enzymatic methods to convert glycerol into platform chemicals that can be used to produce value-added products.

The focus of this research is to understand how the physiochemical functionality of molecules at the nano- and micro- scales can be controlled to improve macroscopic properties of food and its overall healthfulness.
One of the goals of this research theme is to understand the mechanisms of structure formation in food emulsions and nanoemulsions and how the overall structure might be modified through the interactions between nanodroplets, surfactants, fat crystals and other additives. The knowledge gained from this research is be used to develop multifunctional bio-based nano- and micro- structures to deliver active components in food without any loss in functionality during processing and digestion (e.g. prevention of lipid oxidation or protection against adverse environment of GI tract so that functionality can be delivered in the targeted organs). The effectiveness of the controlled release matrix to deliver and release an active ingredient to the right place at the right time in the human body (both in-vitro and in-vivo studies) are also determined.
Various other research topics include:
- controlling nanostructure and self-assembly at interfaces for the development of novel food matrices with improved rheology and stability
- development of pulse protein-stabilzied nanoemulsions
- stability of W/O emulsions and nanoemulsions
- pickering emulsions for stability and controlled release applications

Principal Investigator: Chris Eskiw
Research under this theme focuses on how nutrient availability and sensing impacts the aging process by altering genome function and organization. It has long been known that restricting nutrient/calorie intake promotes health and extends lifespan. However, the consequences of reduced nutrient uptake are not understood at the most basic level of our biology -- our genes. Understanding how our genes respond to nutrients is essential in order to design therapies/dietary strategies and to identify naturally occurring molecules found in foods to combat age-related disease and increase lifespan. The work in Dr. Eskiw’s laboratory aims to identify not only the genes involved in mediating health and longevity but also the mechanisms that drive this. Furthermore, the goal is to understand how genome folding influences gene expression leading to increased health and longevity.
