A series of single factor experiments were conducted to evaluate effects of high-pressure intensity(200-600 MPa) and pressure-holding time(10-30 min) on preservative properties of roast chicken during storage at 4 ℃.Results indicated that sterilization effect exhibited an obvious improvement with the increase of high-pressure intensity.A better sterilization effect at a high-pressure intensity of 500 or 600 MPa was observed,which reduced total bacterial and lactic acid bacterial counts by three or four magn...
