Research interests

  •  Effects of food processing on chemical hazards in foods including food allergens, mycotoxins and bacterial toxins, their detection and methods to reduce the potential risks/hazards in processed foods.
  • Developing novel food processing technologies using thermal and non-thermal (high pressure, PEF, ultrasound) techniques for detection and inactivation of high risk microbial contamination in perishable fruits and vegetables to improve food safety.
  • Developing processing methods, extraction techniques and bioprocessing to develop value-added products with enriched bioactive compound.
