Abstract:
This study investigated the effects of high pressure (0.1, 150 and 400 MPa) and the aging method (wet- and dry-aging) on the quality characteristics of pork loin. Pork pressurized at the target pressure levels was aged at 1 °C for 3 weeks in vacuum packaging (wet-aging) or a moisture/vapor permeable bag (dry-aging). The water binding properties, shear force, color, volatile compounds and microbial counts were estimated as the quality characteristics of aged pork. Despite dry-aged pork having distinctive flavor characteristics, high moisture loss during aging was estimated as the most important factor that affected the quality of aged pork. Alternately, wet aging showed advantages of producing tender and juicy pork, and moderate pressurization (150 MPa) modified or improved the qualities of wet-aged pork. Consequently, this study indicated that pressurization followed by wet-aging had potential application as a meat tenderizing technique.
