Project

Characterisation and bioactive properties of protease inhibitors and phenolic components from Australian wattle (Acacia victoriae Bentham) seed

Summary

Wattle seed (Acacia victoriae Bentham) is one of the most economically viable Australian native plants and has considerable potential as a food ingredient in raw and roasted forms. However, the presence of anti-nutritional protease inhibitors and polyphenols in acacia seed has not been studied in detail, particularly in reference to their bioactive properties, such as anti-cancer, anti-hypertensive, antimicrobial and antioxidant activities. Our research interest is focused on the characterisation of protease inhibitors and polyphenols from wattle seeds, the effect of roasting on their chemical composition and their in vitro bioactivities. We believe our results could enhance and project the image of Australian native foods internationally, especially the value of wattle seed products in the growing healthy foods market and provide better social and economical returns for the Australian wattle-growing regions.
