Profile Image
Associate Professor

Research | Current

  • Bioactive and functional food research including extraction & separation of bioactives from waste by-product (e.g. antioxidants, functional lipid, collagen, gelatine, carotene and vitamin E), evaluating and developing suitable bioactive delivery systems (including microencapsulation) for bioactive components such as omega 3 fatty acids, phytosterols and vitamins.
  • Functiona Food Product Development
    Utilisation of functional food ingredients to formulate value-added and specialty food products; sensory evaluation for product acceptance; relation of food properties and sensory attributes.
  • Lipid science and antioxidant including emulsion properties and stability, characterization of fats & oils, omega-3 fatty acids, lipid oxidation and antioxidant determination.
  • Relation of food properties and processing including physicochemical, nutritional, sensory qualities and microbiological safety of foods and both thermal (spray drying, common heating treatment e.g., baking, pan fried) and non-thermal (e.g. high pressure processing) processing as well as post-harvest treatment.
  • Food Waste Utilisation
    Utilisation of food processing waste for water treatment; extraction of antioxidants from food waste.
  • Biodegradable / Nanocomposites Food Packaging
    Characterisation and application of biodegradable and nanocomposites materials as food packaging; shelf life of food, interactions between food components and nanocomposite food packaging materials.
