Abstract

The physicochemical properties and sensory characteristics of loins from crossbred Jeju black pigs from 4 different farms (Jl, J2, J3 and J4) were investigated. The approximate composition of loins were as follows; moisture 73.26∼74.75%, crude protein 22.78∼23.85%, crude fat 0.85∼1.81% and ash 1.23∼1.35%. The unsaturated fatty acid (60.21∼62.33%), pH (5.57∼5.70), water holding capacity (64.22∼69.40%), cooking loss (28.27∼30.45%), Hunter's L＊ (53.02∼55.64), a＊ (8.71∼9.87) and b＊ value (6.95∼7.29) of loins were not significantly different along the 4 samples (p>0.05). The crude fat contents and total amino acid (21.29%) of loin from farm J2 were higher than those from the others, and the hardness and chewiness were lower compared to those from farm Jl (p<0.05). The loin from farm J2 had a good score in sensory characteristics with regard to the taste (5.22), aroma (4.80), tenderness (5.30), juiciness (5.09) and palatability (5.33) of loins evaluated by the 7-point hedonic scale.

제주도 개량 흑돼지 고기의 이화학적, 관능적 품질 특성을 알아보기 위하여 4개 농진(Jl, J2, J3및 J4)에서 생산한 등심의 일반성분, 아미노산 함량, 지방산 조성, 물리화학적 특성을 분석하고 관능평가를 하였다. 등심의 수분 함량(73.06∼74.75%), 조단백질 함량(22.78∼23.85%), 조회분 함량(1.23∼1.35%), pH(5.51∼5.70), 불포화지방산(60.21∼62.33%), 보수력(64.22∼69.40%), 가열감량(28.17∼30.45%), Hunter's L＊(53.02∼55.64), a＊(8.71∼9.87) 및 b＊(6.95∼7.29) 값은 4개 농장간의 유의적 차이가 없었다(p>0.05). 등심의 조지방(0.85∼1.81%)과 총아미노산 함량(18.85∼21.19%)은 J2농장의 것이 제일 높고, 경도와 저작성은 J2농장의 것이 가장 낮아 Jl농장의 것과 현저한 차이를 보였다(p<0.05). 7단계 기호척도법에 의한 관능 평가 결과, J2농장의 등심이 맛(5.22), 향(4.80), 연도(5.30), 다즙성(5.09) 및 종합적 기호도(5.33)가 모두 가장 우수하였으며 향을 제외하면 Jl농장의 등심과 유의적 차이를 나타내 었다(p<0.05).
