Abstract/Executive Summary
Bacterial contamination of chicken meat poses significant health and economic risks globally. This study explored the potential of Avocado Peel Extract (APE) as a natural antimicrobial agent to inhibit microbial load. Raw chicken meat samples were treated with varying APE concentrations (10%, 1%, 0.1%) and a negative control. Microbial Load Count (MLC), measured in colony-forming units per gram (CFU/g) via Aerobic Plate Count (APC) after 24-hour incubation at 37°C showed the following mean values: Control (1.73E+09 CFU/g), 10% APE (1.83E+09 CFU/g), 1% APE (3.03E+09 CFU/g), 0.1% APE (2.17E+09 CFU/g). One-way Analysis of Variance (ANOVA) revealed no statistically significant difference (p=0.149). The lack of significant antimicrobial activity may be due to the absences of flavonoids in the APE, storage conditions, and the complex microbial community in chicken. Future studies should standardize avocado peel processing, optimize extraction, increase sample size, investigate more extended incubation periods, and analyze specific bacterial populations. This research, while not demonstrating significant antimicrobial activity, highlights the potential of agricultural waste for sustainable food preservation.
