Abstract

This study was carried out to investigate the quality characteristics of brands pork: a crossbred between Korean native and wild pigs (Y), a commercial LYD breed fed with probiotics (J), and a commercial LYD fea without probiotics (M). The moisture and crude ash content of Y treated pork was higher than those for J and M brands, but the crude fat content of J pork was significantly lower (p<0.05) than Y and M brands. The moisture and crude fat contents of Y gilts were higher (p<0.05) than those of barrows. The pH values of Y gilts were higher (p<0.05) than those of gilts of J and M brands. The L and W values of Y pork were lower (p<0.05) than with J and M brands. The springiness value of J pork was significantly higher (p<0.05) than Y and M porks. The sensory scores of Y pork were higher than pork of J and M. The juiciness of gilts of M brands was higher (p<0.05) than for barrows. With regard to the fatty acid profiles among the pork loins, linoleic and arachidonic acid contents of Y pork were higher than with J and M, while the palmitic, pamitoleic, stearic, and oleic acid contents were lower. The saturated fatty acid (SFA) content of Y pork was lower than that for J and M ones, while the unsaturated fatty acids (USFA), essential fatty acids (FFA), USFA/SFA ratio, FFA/SFA ratio, and EFA/USFA ratio were higher. The stearic acid content of M barrows was higher (p<0.05) than that for gilts.

시중에 유통 중인 브랜드 돈육의 품질 특성을 조사하기 위해 3개 브랜드(Y처리구 :재래돼지$\times$멧돼지, 맥강과 한약제 급여; J처리구 LY$\times$D, 무항생제, 생균제 급여; M처리구 :LY$\times$D)돈육 등심을 구매하여 품질 특성을 분석하였다. 수분과 조회분 함량은 Y처리구가 J와 M처리구에 비해 높았지만, 조지방 함량은 J처리구가 Y와 M처리구에 비해 현저하게 낮았다(p<0.05). Y처리구의 미경산돈이 거세돈보다 수분과 조지방 함량이 현저하게 높았다(p<0.05). Y 처리구의 미경산돈의 pH는 J와 M처리구의 미경산돈에 비해 현저하게 높았다(p<0.05).돈육의 L(명도)값과 W*(백색도)값은 Y처리구가 J와 M처리구에 비해 현저하게 낮았다(p<0.05). 조직 특성 중 탄력성은 J처리구가 Y와 M처리구에 비해 현저하게 높았다(p<0.05). 관능적 점수는 Y처리구가 J와 M처리구에 비해 높았고, M처리구의 미경산돈은 거세돈에 비해 다즙성이 현저하게 높았다(p<0.05).지방산 조성 중 linoleic acid와 arachidonic acid 함량은 Y처리구가 J와 M처리구에 비해 높았지만 palmitic acid, pamitoleic acid, stearic acid 및 oleic acid 함량은 낮았다. 포화지방산 함량은 Y처리구가 J와 M처리구에 비해 낮았지만, 불포화지방산, 필수지방산, 불포화지방산/포화지방산 비, 필수지방산/포화지방산 비 및 필수지방산/불포화지방산 비는 가장 높은 함량을 나타내었다. 성별 간에는 M처리구에서 거세돈이 미경산돈에 비해 stearic acid 함량이 현저하게 높았다(p<0.05). 이상의 결과를 종합해 볼 때 재래돼지$\times$멧돼지를 교잡하여 맥강과 한약재를 급여한 Y처리구가 J와 M처리구에 비해 육의 이화학 특성과 관능적 특성에서 우수한 것으로 나타났다.
