This study aims to assess the antioxidant efficacy of mulberry (Morus alba) polyphenol (MP) in vacuum-packed dried minced pork slices stored at room temperature for 20 days. Dried minced pork slices were manufactured with 20 g/kg, 40 g/kg MP or 0.2 g/kg BHT, respectively. The results presented that MP significantly reduced TBRAS values increment and carbonyls formation while decelerated sulfhydryl losses in dried minced pork slices. Dried minced pork slices manufactured with MP gained higher a* value (P < .05) and lower L* value (P < .05) than the control. In additional, MP also improved microbiological stability and sensory properties of dried minced pork slices during storage. All these results demonstrated that MP as a natural antioxidant might have remarkable potentiality in meat products.
