Dr. Craig Davis

Research interests include the extraction of bioactive chemicals from natural (e.g. food) products. Examples include the extraction of drugs from plants and the use of crude plant extracts for their anti-microbial, anti-oxidant, anti-browning, anti-cancer and anti-inflammatory activity. The extraction of essential oils and other terpenoid compounds is of particular interest. 


Sub-Critical Co2

The production of essential oils from Sandalwood using sub-critical CO2.

Consultancy services to the food industry in grains and nuts, honey, seafood, horticulture, etc.

Scale-up and commercialisation of alternative extraction technologies for the production of bioactive materials from nature.

Decades of experience

passionate advocate for the use of natural products for health and wellbeing. I also have a strong interest in the addition of value to biological resources and in the utilization of processing wastes. I currently work as a consultant to the food industry, predominantly in South East Queensland. Prior to this, I spent more than 20 years working in Queensland agriculture and food processing until the research priorities changed and support for primary industries reduced. I would like to use my skills to help guide students into science careers.


Research Topics

Bachelor of Science Degree in Biochemistry and Life Sciences at Griffith University (1983).

Honours Degree (First Class) in Biochemistry at Griffith University (1984).

         Topic: Effect of ethanol and its metabolites upon hepatic collagen metabolism.

Doctor of Philosophy Degree at Griffith University (1990).

Dissertation Topic: Studies of hepatocyte function in experimental liver disease.


Churchill Fellowship (1999). This work evaluate the opportunities to value-add to food (particularly seafood and seafood wastes) and involved a 3‑month study tour to the US, Canada, Europe and Asia. The outcomes of this fellowship have been broadly and repeatedly applied to local Queensland projects in many commodities (fruit and vegetables, seafood, grains, meat and juices) since the tour was completed.
