초록
본 연구는 일반적으로 낮은 육질등급으로 유통되는 한우수소고기에 대하여 소비자 관능평가를 실시하여 사회인구학적 요인과 한국소비자들의 관능특성간에 어떠한 관계가 있는지 알아보고, 이 결과를 한국소비자들을 위한 요리방법별 부위별 맛 예측 모델을 설정하기 위한 기초자료로 활용하고자 수행하였다. 24개월령 한우수소를 도축한 후 업진, 보섭, 채끝, 등심, 꾸리, 홍두깨, 목심, 설깃, 우둔, 양지부위를 분리하여 전국 소비자 650명을 대상으로 탕, 그릴 및 구이형태로 각각 조리하여 연도, 다즙성, 향미 및 전반적인 기호도를 평가한 결과 탕형태로 조리된 한우수소고기는 거주지역, 연령, 성별, 직업, 고기섭취습관 및 10개의 부위에 대한 관능특성 4가지 요인(연도, 다즙성, 향미 및 전반적인 기호도)과 모두 관련이 있는 것으로 나타났다. 스테이크 형태인 경우 쇠고기에 대한 기호성향이 거주지역, 연령 및 식습관 등과 유의적인 차이가 없는 것으로 나타났으나 직업, 가족수, 가계수입 및 부위에 따라서는 유의적인 차이가 있는 것으로 나타났다(p<0.01). 구이형태인 경우 거주지역, 연령, 직업, 가계수입, 식습관 및 부위에 따라 기호도 성향에 차이가 있었다. 또한, 한우수소고기의 관능평가 결과에 대하여 주성분 분석을 실시한 결과 요리방법에 따라 연도, 다즙성, 향미 및 기호도가 부위별 관능특성에 미치는 가중치가 다른 것으로 분석되었다. 결론적으로 한국소비자들은 동일한 조건의 쇠고기일지라도 요리방법 및 부위에 따라 쇠고기 맛을 평가하는 기호도에 차이가 있었으며 이러한 점을 고려하여 부위별요리방법별 맛 예측모델을 확립한다면 한우고기를 차별화할 수 있는 유통시스템 개발이 가능할 것으로 생각된다.
Abstract
This study was conducted to investigate the relationship between the socio-demographic factors and the Korean consumers’ palatability evaluation and to collect the sensory information for development of prediction palatability model of Hanwoo beef. Ten cuts〔Abjin (short plate), Bosup (top sirloin), Cheggt (striploin), Dngsim (loin), Guri (chuck tender), Hongduke (eye of round), Moksim (chuck roll), Sulgit (bottom round), Udoon (top round), Yangi (brisket)〕 were separated from 10 Hanwoo bulls beef(～24 months old) and prepared with the same manner for 3 different cooking methods such as boiling, grilling and roasting. The cooked beef samples were served to 650 consumers recruited from Seoul, Joongbu, Honam and Youngnam locations and evaluated tenderness, juiciness, flavor and overall acceptability. The living location, age, gender, occupation, eating habit and cut were significantly related with the sensory properties when bull beef were cooked as boiled cooking(p<0.05). In grill cooking, only occupation, income and cut had the significant effect on the overall acceptability of Hanwoo bull beef(p<0.01). When bull beef were cooked as Korean traditional roast cooking, consumer’s sensory properties were significantly different by the living location, age, occupation, income, eating habit of consumers and cut(p<0.05). Also, results from the principal component analysis showed that palatability scores of Korean consumers were decided with different contribution scores of tenderness, juiciness, flavor and overall acceptability of cut depending on cooking methods. In conclusion, Korean consumers’ palatability for Hanwoo bull beef were related with the socio-demographic factors and the sensory results were different by cut and cooking methods.
