Investigating Ripening Stages and Bioactive Profiles of Burdekin Plum to Inform Harvest Timing

About the Research Project

Burdekin plum (Pleiogynium timoriense) is an Australian native fruit recognised for its high levels of phenolics, anthocyanins, and strong antioxidant capacity. Not only is Burdekin plum used as a popular ingredient in jams, juices, and fruit salads, but it has also been traditionally used by Aboriginal Australians to treat colds, headaches, and sores.    

This project examines the relationship between fruit maturity stage, physical ripening indicators (colour and firmness), and bioactive composition (phenolics, flavonoids, anthocyanins, antioxidant activity) to further support the commercial cultivation of the Burdekin plum.   

This project strengthens First Nations' knowledge and agricultural systems and advances scientific research on native resources. By generating new physiological and biochemical insights into the Burdekin plum, the project contributes to building capacity in emerging research areas around native food and medicinal plants, strengthening both applied science and community-led innovation. The project embeds a meaningful First Nations community engagement component, elevating Indigenous knowledges, strengthening culturally informed research practice, and modelling Indigenous-led pathways in science. It positions the project as an exemplar of how scientific research and Indigenous knowledge systems can be brought together with integrity.

Impact  

• A comprehensive physiological and biochemical profile of Burdekin plum across key ripening stages. 
• Evidence establishing the relationship between ripening stage and bioactive compound development. 
• Foundational data to inform future work on harvest timing and postharvest handling strategies for native fruits.
