Abstract Purpose： To evaluate the application of ultra-high pressure technology for sterilizing hand tore special wild mountain pork. Methods： Process parameters optimization was performed using one-factor-at-a-time method and response surface analysis based on total plate count and comprehensive quality evaluation. Results： The best sterilization parameters were determined as follows： temperature 26.38 ℃, pressure 486.94 MPa, and press-holding time 15.92 min. Conclusions： High pressure technology can improve productivity, reduce nutrient losses, maintain the quality of wild mountain pork well and therefore has a bright application and popularization prospect.
