About Osaana Donkor

Dr Osaana Donkor is a senior lecturer in Food Science in the College of Health and Biomedicine. Osaana has experience in food microbiology, safety and preservation as well as probiotics and food chemistry. 

He is also experienced in fermentation biology for the production of yoghurt and dairy products. In addition, Osaana has experience in using mammalian primary cell cultures as well as adherent and suspension cultures. Osaana is a consulting analytical chemist for institutions and manufacturing companies.

Osaana is also a reviewer for several journals in the fields of Food Science, Nutrition and Food Chemistry.

He currently spends his time lecturing, supervising PhD students and conducting his own research. Some of his research interests include:

  • food safety – toxins, allergens and pathogens
  • immunostimulatory properties of probiotics
  • the effect of probiotic bacteria in modulating Th17 and T regulatory cells immune responses
  • probiotics and prebiotics – the production of short chain fatty acids and immunity
  • bioactive peptides derived from fish by-catch and fish waste for the treatment/prevention and/or management of colon cancer
  • studies of anti-carcinogenic peptides released in probiotic yoghurt
  • the effect of bioactive compounds from native plants - Carpobrotus rossii on a colon cancer model.

Qualifications

  • PhD (Food Science and Technology), Victoria University, Australia, 2008
  • Bachelor of Science (Hons.), Victoria University, Australia, 2004
  • Diploma of Applied Science (Biological Sciences and Chemical Laboratory Technology), Victoria University, 2000
