Research
Major Responsibilities/ Research Interests
1. Emerging Processing Technologies
My research focuses on emerging processing technologies and the use of near-critical and supercritical water and carbon dioxide to treat biomass and agricultural materials for use in nutraceutical, food and industrial applications. We have worked on protein, and starch processing. Main areas are:
- Sub/supercritical fluid processing (supercritical CO2, subcritical and supercritical water, pressurized fluids for extraction, fractionation, reaction and particle formation)
- Ultrasound processing (extraction, homogenization, emulsion, reaction, etc)
- High Pressure Processing and High Pressure Processing assisted by Temperature to treat crops and food products.
2. Unit Operations for Food/By-product Processing
My research group has vast experience on food/Natural health product/by-product processing using various unit operations. We have processed food and by-products using conventional methods as well as innovative processing techniques:
- Adsorption (Compounds)
- Extraction (Bioactives and value-added compounds)
- Fractionation (Extracts, Bioactives)
- Reaction of biopolymers (Films, Gels)
- Particle formation (Powders)
- Drying and pasteurization
- Food industry waste treatment
3. Mathematical modeling and simulations
We have also performed mathematical modeling and computer simulations:
- Solubility determination and modeling
- Kinetic modeling
- Extraction simulation
Crops that are currently under study in my research team include potato, flax, wheat, triticale, lentils and peas. Among crops previously studied are barley, canola, faba beans, coffee and cocoa beans, guarana seeds, carrots, tomatoes, Echinacea roots and tea leaves.
I maintain fruitful collaborations with researchers from renowned centers and universities in Japan, Germany, The Netherlands and Brazil. Thus, I provide an exciting research program in the area of high pressure processing, nanotechnology and supercritical water technology.
Teaching
Graduate/PDF Career Opportunities
Graduate students and PDFs with interest in supercritical fluid technology are encouraged to apply. Ideal students and researchers will have a degree in food engineering or chemical engineering, but students from other disciplines with interest in supercritical water technology, nanoencapsulation or high pressure processing will also be considered.
