Abstract: This study evaluated the efficacy of Colocasia esculenta (CLE) and Eucalyptus globulus (ELE) leaf extracts in preserving the quality of frozen shrimp. Shrimps treated with 1.5% CLE exhibited significantly lower total volatile basic nitrogen (TVB-N) (12.47 mg/100 g), trimethylamine (TMA) (6.85 mg/100 g), and bacterial load (3.94 CFU/ml) compared to lower concentrations and the control. Similarly, 1.5% ELE-treated shrimps showed reduced TVB-N (11.28 mg/100 g), TMA (5.85 mg/100 g), and bacterial load (3.92 CFU/ml). The combined treatment (CLE+ELE, 1:1) was the most effective, yielding the lowest TVB-N (9.69 mg/100 g), TMA (5.08 mg/100 g), and bacterial load (3.78 CFU/ml). Sensory scores declined over the 24-week storage period but remained highest for combined treatment (8.62), followed by ELE (8.55) and CLE (8.42). These findings suggest that the combined CLE+ELE treatment at 1.5% concentration effectively enhances the microbial stability and sensory quality of frozen shrimp, making it a promising natural preservative for commercial applications.
