Abstract

This study was performed to compare the effects of binding time(2hr, 4hr, 6hr and 16hr) and pressing condition (1kg, 3kg, 5kg and 10kg) on manufacturing restructured pork. Meat color, in terms of L, a, b showed no significant difference by treatment of binding time. Five kg pressing resulted in the highest red value(P<0.05). In tensile strength, 6 hour treatment showed significant difference ranging in 202.1g for raw restructured pork and 389.0g for cooked restructured pork. Five kg pressing showed the highest tensile strength, 114.6 for raw restructured pork and 303.3 for cooked restructured pork. In hardness, springiness, cohesiveness and chewiness, raw and cooked restructured pork showed insignificant difference regardless of pressing time. In sensory evaluation, four hour treated raw restructured pork showed the highest values of color, binding degree, shape, acceptance, while four or six hour treated restructured pork showed the highest values in cooked restructured pork. Therefore the optimal conditions for manufacturing restructured pork using TGase were four through six hour pressing with 5kg pressure.
