Process Engineering Research to Improve Safety, Quality, & Utilization of Water, Food, & Environment

The Food Safety and Sustainability Engineering (FSSE) Research lab at the University of Alberta focuses on improving the safety, quality, and utilization of water, food, and the environment. We are working towards developing applications of the following advanced, green technologies to improve food safety and overall sustainability of water, food, and the environment. The following are the key research areas:

Antimicrobial Applications of Atmospheric Cold Plasma

• Plasma activated air, water, micro/ultrafine (nano) bubbles, and mist
• Microbial decontamination
• Inactivation of microbial biofilms in the processing environment

Micro/Ultrafine (Nano) Bubble Technologies 

• Microbial biofilm inactivation
• Water treatment

Agricultural and Environmental Applications of Atmospheric Cold Plasma

• Seed decontamination and germination improvement
• Mycotoxin degradation
• Plasma activated water as a green fertilizer and sanitizer for greenhouse and indoor farming - hydroponics and aquaponics

Sanitation, Disinfection & Cleaning in Food Processing Industry

• Conventional antimicrobial interventions (e.g., peracetic acid, lactic acid, citric acid, hydrogen peroxide, dry heat, quats)
• Cold plasma and UV based hybrid treatment development with conventional antimicrobial interventions

Agri-Food Processing & Engineering

• Low-moisture food safety engineering
• 3D printability of plant proteins, carbohydrates, and fibers
• Plant protein and carbohydrate particle formation (gels, powders, emulsions) and functionality improvement (e.g., peas, canola, lentil, faba bean, etc.)
• Conventional agri-food process intensification and development of novel extraction, homogenization, and drying processes

Wastewater Treatment

• Atmospheric cold plasma bubble technology development
• Treatments using ultraviolet and blue light pulses emitted from LEDs
• Microbial decontamination
• Degradation of antibiotics and pesticides in wastewater

UV LED applications

• Microbial decontamination
• Water treatment
