Abstract The negative effects exerted by chemical and thermal preservations on health and food quality have led to a rising interest in the active coating with natural antimicrobials, as a novel alternative. The aim of this study was to prepare and characterize the nanoemulsion incorporated with the mixture of star anise essential oil, polylysine and nisin, then evaluate the influences of nanoemulsion-based active coating (NEAC) on quality attributes and shelf life of Yao meat. Physicochemical, microbial, and sensory properties were regularly monitored at day 1, 4, 8, 12, 16, 20. Prepared nanoemulsion with 1.5% soy protein isolate (SPI) showed good stability with the smallest particle size (97.1 ± 0.8 nm) in 45 days, and better antimicrobial effect on microorganisms in Yao meat. The application of NEAC caused no effect on moisture content of the meat samples for 20 days. However, the reduction of pH and total volatile basic nitrogen of meat samples were significant (p
