초록

본 연구는 돈피 젤라틴 분말의 첨가 수준이 떡갈비의 품질특성에 미치는 영향을 규명하고자 실시하였다. 떡갈비의 단백질 함량은 대조구가 가장 낮은 수치를 나타내었으며 돈피젤라틴 분말 4% 처리구가 가장 높은 수치를 나타내었다(P<0.05). 수분 함량은 돈피 젤라틴 분말을 첨가할수록 점차 높아지는 경향을 보였으나, 지방 함량은 돈피 젤라틴 분말 첨가량이 증가함에 따라 점차 감소하는 경향을 나타내었다. 가열 전과 후 명도와 적색도는 돈피 젤라틴 분말 첨가량이 증가함에 따라 유의적으로 감소하였으며, 황색도는 증가하였다(P<0.05). 가열감량, 직경감소율과 두께감소율은 돈피 젤라틴 분말 첨가량이 증가할수록 감소하였으며, 경도는 돈피 젤라틴 분말을 첨가할수록 높은 수치를 나타내었고 3% 처리구와 4% 처리구가 가장 높은 수치를 나타내었다. 검성과 씹음성은 돈피 젤라틴 분말의 첨가량이 증가함에 따라 높은 수치를 나타내었다. 관능적 특성은 모든 돈피 젤라틴 분말을 첨가할수록 색도와 다즙성에서 대조구보다 우수한 평가를 받았으며, 이외 모든 관능평가 항목에서 3% 처리구가 유의적으로 가장 우수한 평가를 받는 것으로 나타났다(P<0.05). 이러한 연구 결과를 바탕으로 돈육 떡갈비에 돈피 젤라틴 분말을 첨가하여 품질 특성을 분석한 결과 2~3%의 돈피 젤라틴 분말을 첨가하여 우수한 떡갈비를 제조할 수 있을 것으로 판단된다.

This study evaluated the effect of the addition of pig skin gelatine powder with different levels on the chemical compositions, cooking characteristics, and sensory properties of tteokgalbi. Tteokgalbi was produced from products containing 0% (control), 1%, 2%, 3%, and 4% pig skin gelatine powder. The protein and moisture contents of samples increased with an increase of pig skin gelatin powder levels. In addition, the pH value and CIE $b^*$ values of uncooked and cooked samples increased with increasing amount of pig skin gelatin powder. However, cooking loss, diameter reduction, and thickness reduction of samples decreased with an increase of gelatin powder contents. The hardness, gumminess, and chewiness of samples increased with an increase of gelatin powder contents, and sensory evaluation of tteokgalbi containing 2~3% pig skin gelatin powder was the highest. Therefore, usages of pig skin gelatin powder can improve quality characteristics of tteokgalbi.
