Abstract

Crossbred pigs (female, 198 days old, $102{\sim}118kg$, Tamra Marketing Farm) were fed a diet supplemented with tangerine peel fer an extended period to study its effect on the physicochemical properties and palatability of the pork. The samples for this study consisted of the pork from pigs fed a diet without tangerine peel (T0), and the pork from pigs fed a diet containing 8% tangerine peel during the entire breeding period, from early pregnancy through the finishing period (T1). The pH Hunter's $L^*$ value, water holding capacity, freezing loss, thawing loss, cooking loss, hardness, springiness, cohesiveness, sensory raw meat color and cooked meat palatability of loin and belly were not significantly different between T0 and T1 pork (p>0.05). However, the Hunter's $a^*\;and\;b^*$ value, gumminess, shear force value (SFV) and smell were significantly higher in meat from loin of T1 than T0 pigs (p<0.05). Thus T1 pork exhibited an improved SFV, DPPH reduction and aroma of cooked belly meat (p<0.05).

감귤피를 급여하지 않은 돼지고기(대조구, T0)와 임신초기부터 분만 후 자돈기, 육성기 및 비육기까지 전 사육기간 동안 8%의 감귤피를 급여한 돼지고기(감귤피 급여구, T1, 198일령, $102{\sim}118kg$)의 물리화학적 특성과 기호도를 비교하였다. 등심과 삼겹살의 pH, 명도, 보수력, 동결감량, 해동 감량, 가열감량, 경도, 탄성, 응집성, 생육의 색깔 및 가열육의 종합적 기호도는 T0와 T1 사이에 유의적 차이를 보이지 않았다(p>0.05). 등심의 적색도, 황색도, 뭉침성, 저작성 및 전단력, 그리고 삼겹살의 항산화력, 전단력, 생육의 냄새 및 가열육향은 T0보다 T1이 높게 나타났다(p<0.05).
