Abstract
This study examines the nutritional composition of five Australian Indigenous spices: cinnamon myrtle (Backhousia myrtifolia), curry myrtle (Backhousia angustifolia), native ginger (Alpinia caerulea), native turmeric (Curcuma australasica), and mountain pepper berry (Tasmannia lanceolata). Compositional analysis revealed high protein levels in native turmeric (11.47% wt/wt) and curry myrtle (10.28% wt/wt), positioning them as promising ingredients for protein-rich or plant-based foods, offering novel options for flavour and colour enhancement. Macronutrient and mineral profiles were analysed using HPLC, Inductively Coupled Plasma Optical Emission Spectrometry, and enzymatic assays. Native turmeric had the highest energy at 1451 kJ/100 g due to its 54.33% wt/wt starch content, while mountain pepper berry was highest in fibre (54.78% wt/wt) and lipid (12.30% wt/wt) levels. Mineral analysis highlighted native ginger’s high iron (114 mg/kg) and molybdenum (1,058 mg/kg) content, with native turmeric rich in zinc (105.9 mg/kg). These findings underscore the potential of these spices as functional ingredients in food, providing health benefits like enhanced digestion from high fibre or natural thickening from starch-rich spices. Furthermore, this data support the creation of Nutrition Information Panels and global market integration, advancing the use of sustainable native resources and opportunities for food industry innovation.
