Profile Image
Honorary Academic

Research | Current

  • Chemistry and Technology of processing of food products, with special emphasis on functional foods
  • Transfer of technology to industry by way of national and international consultancies. Minimal processing of fruit and vegetable products
  • Functional foods such as soy isoflavones and vitamin D and changes during processing. Development of novel methods of processing including energy efficient methods of drying

Current projects

  • Dehydration
    Mathematical modelling of mass transfer during osmotic drying of fruit tissues coated with edible coatings (with Prof Zhao Weibiao of National University of Singapore).
  • Postharvest Technology
    Study of the effect of 1-Methylcyclopropene on the quality of fresh-cut fruits and vegetables.
  • Functional Foods
    Effect of processing on soy isoflavones, and vitamin D2 from mushrooms and its bioavailability, protein functionality.
