Abstract

A total of 100 pigs were used to investigate the effects of pig breed on proximate, physicochemical, cholesterol, amino acid, fatty acid and sensory properties of loins. Crossbred pigs were alloted into one of five experimental groups [×Duroc(LYD), ×Berkshire (YBB), British Berkshire(BB), Kagoshima Berkshire(KB), Korean native black pig×Wild boars(KW; Sus coraanus)]. Pigs were slaughtered at 110 kg live weight. Moisture content was significantly(p<0.05) higher in KW than those of other pig breeds. Crude protein content was significantly(p<0.05) higher in YBB and KW than in LYD, BB, and KB. Cholesterol content was significantly(p<0.05) higher in YBB than those of other pig breeds. WHC and pH value had lower and shear force had higher(p<0.05) in YBB than those of other pig breeds. In color, LYD was significantly(p<0.05) higher in L* than those of other pig breeds. There was no significant different in a* and brittleness value among the breeds. In fatty acid and amino acid composition, KW had a higher(p<0.05) UFA/SFA, EFA/UFA ratio and EAA content but lower (p<0.05) SAAA. Total amino acid content was significantly(p<0.05) higher in LYD(20.44%) and BB (20.81%) than those of other pig breeds. In fresh meat, breeds affected meat color, drip loss, marbling score, and overall acceptability(p<0.05). Nevertheless, no significant differences were found among the breeds in the sensory parameters evaluated in the cooked meat, except for flavor

[Landrace×Yorkshire]×Duroc(LYD) 및 [Yorkshire×Berkshire]×Berkshire(YBB) 삼원교잡종과 흑색계 영국 Berkshire(BB; British berkshire), 가고시마 Berkshire(KB; Kagoshima Berkshire), [재래돼지×멧돼지(KNW; Native black pig×Wild boars)] 이원교잡종에서 생산된 돼지 100두를 생체중 110 kg 도달시 도축한 후 등심을 채취하여 분석하였다. 수분 함량은 KW, 조단백질은 YBB와 KW, 콜레스테롤 함량은 YBB가 다른 품종들보다 유의적으로 높았다(p<0.05). 다른 품종들에 비해 YBB는 보수력과 pH는 낮고, 전단가는 높았다(p<0.05). LYD에서 명도(L*)가 유의적으로 높게 나타났으며(p<0.05), 적색도(a*)와 파쇄성에서는 품종들 간에 유의적인 차이가 없었다(p>0.05). UFA/SFA와 EFA/UFA 비율과 EAA은 KW가 높게 나타났으나(p<0.05) SAAA는 유의적으로 낮았다(p<0.05). 총 아미노산 함량은 LYD와 BB가 각각 20.44%, 20.81%로 다른 품종에 비해 유의적으로 많았다(p<0.05). 신선육 상태에서 품종은 육색, 드립로스, 마블링과 전체적인 기호도에 영향을 미쳤지만(p<0.05), 조리육의 경우 풍미를 제외한 관능검사 항목에는 영향을 미치지 않았다(p>0.05).
