Characterisation of kafirin-polysaccharide edible coatings for delivery of bioactive compounds in spray coating food applications

Supervised by Professor  Indrawati Oey, and Dr, Azam Ali

About

Stephen comes from Kenya, where he completed his Undergraduate degree in Food Science and Technology at Egerton University (Nakuru). He went on to obtain a masters’ degree in Food Science and Technology at Curtin University (Australia).
He has worked in the meat processing industry in Kenya, working with individual farmers and farmers' cooperatives in livestock production, processing/value addition and marketing of livestock products,

Project Outline

  • Optimization of coating formulation using a selection of plant proteins and polysaccharides incorporated with essential oils.
  • Characterization of surface, structural, mechanical and bioactivity of the edible coatings
  • Phase modification of coating forming emulsion using physical, chemical and mechanical techniques
  • Application and characterization of coatings applied using spray coating technique
  • Application and study of edible coatings applied on fresh raw and cooked salmon fillets
