Agriculture and Food Process Engineering Research

Agri-Food Processing and Engineering 

  • Novel extraction, homogenization, drying processes (e.g., peas, canola, lentil, faba bean, etc.)  
  • Plant protein and carbohydrate particle formation (gels, powders, emulsions) and functionality improvement
  • 3D printability of plant proteins, carbohydrates, and fibers  
  • Atmospheric cold plasma based continuous process development

Antimicrobial Applications of Atmospheric Cold Plasma

  • Plasma activated air, water, micro/ultra fine bubbles, and mist 
  • Microbial decontamination 
  • Inactivation of microbial biofilms in processing environment 

Agricultural and Environmental Applications of Atmospheric Cold Plasma

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

UV LED applications

  • Microbial decontamination 
  • Water treatment

Wastewater Treatment

  • Atmospheric cold plasma bubble technology development
  • Treatments using ultraviolet and blue light pulses emitted from LEDs
