Abstract This study aimed to investigate the extraction of total phenolic compounds of sugarcane bagasse using various solvents. In addition, the Sugarcane Bagasse Water Extract (SBWE) was used in refrigerated fresh meat as natural preservative. The fresh meat was dipped into water solutions containing various phenolic compounds concentrations (T1:125, T2:250 and T3:500 ppm). During 10 days of storage at 4 °C for all the treated samples were compared with untreated one. The results revealed that SBWE showed relevant values of total phenolic compounds (17.90 mg/g) and total flavonoids content (4.50 mg/g), as well as 45.90% of antioxidant content. On the other hand, microbiological examination and sensory evaluation have turned out to be the best treatment for T3:500 ppm. The SBWE showed an antibacterial impact on Staphylococcus sp. and a reduction in the Total Plate Count and in the group of Psychrotrophs. The shelf-life of refrigerated fresh meat treated with SBWE by dipping it into water solutions was also extended to more than 10 days.
