Abstract

Eogeul-tang is a traditional Korean soup dish made from dried pollack, minced beef, and tofu. This comparative study analyzed the quality characteristics of Eogeul-tang by varying the added amounts of cow gristle. The objective of this study was to analyze Eogeul-tang to promote its functionality and increased consumer preference. Collagen contents were $18.08{\pm}0.13g$ and $22.17{\pm}0.14g$ per 100 g of dried pollack skin and knee cartilage of cow, respectively. The overall collagen content was higher in the knee cartilage of cow. Different amounts of cow gristle (25%, 50%, 75%, and 100%) were added to traditionally cooked Eogeul-tang, and the general composition of Eogeul-tang was analyzed. Significant differences were exhibited in the amounts of water content, crude protein, crude fat, and crude ash depending on the added amounts of cow gristle. Moreover, the collagen content also significantly increased as the amount of gristle content increased. In particular, significant increases in the amounts of collagen components, including proline, glycine, and alanine were observed with increasing amount of gristle. When a sensory test was conducted on Japanese, overall preference values were highest for Eogeul-tang composed of 25% beef and 75% gristle compared to traditionally cooked Eogeul-tang. In conclusion, the study results promote the functionality of collagen as well as the increased quality of Eogeul-tang added with cow gristle manufactured by traditional cooking methods.

본 연구는 콜라겐이 풍부한 전통음식인 어글탕의 기능성과 기호성을 증진시키기 위해 콜라겐 함량이 풍부하면서도 지방의 함량이 낮고, 식감을 향상시킬 수 있는 도가니 연골을 첨가하여 어글탕의 품질특성과 관능적 특성을 분석하였다. 전통조리법에서 콜라겐 함량을 증가시키기 위해 육수에 도가니 연골을 첨가하였고 쇠고기 다짐육에 대한 도가니 연골의 첨가량을 25%, 50%, 75%, 100%로 제조하였다. 어글탕의 이화학적 특성으로 아미노산 함량, 콜라겐 함량을 측정한 결과 아미노산 함량, 콜라겐 함량 모두에서 유의적인 차이를 보였다. 콜라겐의 구성 아미노산인 proline(P<0.001)과 glycine(P<0.001), alanine(P<0.001)은 도가니 연골의 첨가량이 증가할수록 유의적으로 증가하였다. 콜라겐 함량 역시 도가니 연골의 첨가량이 증가할수록 유의적으로 높게 나타났는데, 대조군 CE의 collagenous connective tissue는 $0.61{\pm}0.19g/100g$이고 100% 도가니 연골을 첨가한 DE4는 $6.25{\pm}0.44g/100g$으로 최고 10배의 차이를 보였다(P<0.001). 어글탕의 관능평가를 실시한 결과 색(P<0.01)과 감칠맛(P<0.05), 전반적인 기호도(P<0.05)에서 유의적인 차이를 보였으며 전반적인 기호도에서는 쇠고기 25%, 도가니 연골 75%로 만든 어글탕이 가장 높게 평가되었다.
