Abstract

The vacuum packaged ham and loin from low-fat pork cuts were frozen at $-20^{\circ}C$ for 3 months and thawed. Then, the thawed meat was chilled at $3^{\circ}C$, and impacts of chilling period on changes in physical properties of raw meat and cooked meat were investigated. In the case of raw meat, the pH value, $L^*$ value, drip losses, water holding capacity and gumminess of ham increased significantly on the 4th day compared with the 0th day of chilling after thawing. However the cooking losses, hardness and chewiness decreased significantly. The loin showed a similar tendency on the 2nd day of chilling after thawing. In the case of cooked meat, changes in physical properties during chilling period after thawing showed a similar tendency as raw meat, but pH value, $L^*$ value and $a^*$ value did not show significant difference. The springiness and cohesiveness of both raw meat and cooked meat did not show significant difference during chilling period after thawing. The sensory tenderness of ham and loin improved significantly on the 4th day and 2nd day during chilling after thawing, respectively.

돼지고기의 저지방 부위인 뒷다리살과 등심을 진공포장하여 $-20^{\circ}C$에서 3개월간 동결한 후 해동하였다. 해동육을 $3^{\circ}C$에 냉장하면서 냉장기간에 따른 생육과 가열육의 물리적 특성 변화를 확인하였다. 생육의 경우, 뒷다리살은 해동직후(냉장 0일)에 비하여 냉장 4일에 pH 값, $L^*$값, 드립 감량, 보수력, 점성이 상승한 반면, 가열감량, 경도 및 저작성은 유의적으로 낮아지는 현상을 보였다(p<0.05). 등심은 해동 후 냉장 2일에 이와 같은 같은 현상이 나타났다. 가열육의 물리적 특성 변화는 두 부위 모두 생육의 경우와 비슷한 경향을 보였으나, pH 값, $L^*$값 및 $a^*$값은 해동 후 냉장 중 유의적 차이를 보이지 않았다. 생육과 가열육의 탄력성 및 응집성은 두부위 모두 해동 후 냉장 중에 유의적 차이를 나타내지 않았다. 뒷다리살과 등심은 각각 해동 후 냉장 4일과 2일에 연도가 유의적으로 향상되었다(p<0.05).
