Abstract

돼지 뒷다리 부위 주요 근육 4개와 등심 근육으로 제조 된 햄의 이화학적 특성과 관능적 특성을 비교한 결과, 햄 제조에 사용된 원료육의 pH는 Longissimus 근육과 다른 4개의 뒷다리 부위 근육들 간에 차이가 없었으나 햄 제품의 pH에서는 Longissimus 근육 햄에 비해 Rectus femoris 근육 햄이 유의적으로 높은 pH를 나타내었으며(p<0.05), Longissimus 근육 햄의 pH 값이 가장 낮았다(p<0.05). 일반성분을 비교한 결과, 단백질 함량에서만 Longissimus 햄이 Rectus femoris, Semimembranosus, Gluteus medius 근육으로 제조된 햄보다 유의적으로 높았다(p<0.05). 제품색 특성 중 Hunter L 값은 Longissimus dorsi 근육이 가장 높았으며, Rectus femoris, Gluteus medius 근육이 가장 낮은 수치를 나타내었다(p<0.05). Hunter a값은 Rectus femoris, Biceps femoris, Gluteus medius 근육으로 제조된 햄들이 비슷한 수준을 나타내었으며, Longissimus 근육 햄에서 가장 낮았다(p<0.05). 조직감을 조사한 결과, 경도, 탄력성, 응집성, 검성, 씹힘성 모두 근육에 따른 차이가 발견되지않았다(p>0.05). 근육 햄들의 관능적 특성을 조사한 결과, 육안적 색도, 맛, 조직감은 근육간 차이가 없었으며(p>0.05), 풍미는 Semimembranosus 근육으로 제조된 햄이 가장 높은 점수를 받았고, Gluteus medius 근육으로 제조된 햄이 가장 낮았다(p<0.05). This study was conducted to evaluate the quality attributes of cooked hams made with four hind leg muscles (Biceps femoris, Semimembranosus, Rectus femoris, Gluteus medius) and Longissimus dorsi. Muscles were prepared from three market-weighted crossbreeds (<TEX>$L{\times}Y{\times}D$</TEX>) and the pH, proximate chemical composition, color, texture attributes, and sensory properties of cooked pork muscle hams were evaluated. In the raw state, no significant differences in pH were found among the five muscle hams. However, Rectus femoris ham had the highest pH, while Longissimus dorsi ham had the lowest pH (p<0.05). All muscle hams had similar moisture, fat, and ash contents. The protein content (%) was highest in Longissimus dorsi ham (p<0.05). The Hunter L value was highest for Longissimus dorsi ham while Rectus femoris and Gluteus medius hams had the lowest Hunter L values (p<0.05). The Hunter a values were similar in Rectus femoris, Biceps femoris, and Gluteus medius hams, and lowest for Longissimus dorsi ham (p<0.05). Texture attributes were not significantly different among the five muscle hams (p>0.05). The results of sensory evaluation showed that Semimembranosus hams had the highest flavor score, but there were no significant differences among five muscle hams with regard to color, taste, and texture (p>0.05).
