This study aimed to evaluate the preservative effect of Kakadu plum fruit (KPP) in meat. Beef patties were treated with KPP or Sodium metabisulphite (SMB) at different concentrations and stored for 20 days at 4°C. KPP-treated samples had lower Thiobarbituric-acid reactive substances (TBARS) than SMB and the control, indicating better preservation. KPP at 0.2% and 0.4% levels effectively inhibited food spoilage microorganisms, though SMB showed stronger antimicrobial effects. After 20 days, color parameters remained consistent across all samples. A negative correlation was found between KPP and TBARS, suggesting KPP's potential as a natural preservative for extending the shelf-life in meat.
