초록

본 연구는 고 탄수화물식품인 설기떡에 단백질함량이 높은 탈지 밀웜 분말 첨가량(0, 3, 6, 9 및 12%)을 달리하여 제조한 설기떡의 품질특성으로 색도, 기계적 물성, 관능평가, 일반성분, 분지사슬 아미노산 함량을 평가하였다. 품질 특성 평가를 수행한 결과, 색도의 경우 명도(L) 값은 탈지 밀웜 분말 첨가비율이 증가할수록 유의하게 낮아진 반면, 적색도(a)과 황색도(b) 값은 탈지 밀웜 분말 첨가비율이 증가할수록 유의하게 높아졌다. 탈지 밀웜 분말 첨가량에 따른 설기떡의 기계적 물성 측정결과 경도, 검성은 탈지 밀웜 분말 첨가비율이 증가할수록 유의하게 높아진 반면, 씹힘성, 탄력성과 응집성에서는 유의하게 낮아졌다. 탈지 밀웜 분말 첨가량에 따른 설기떡의 관능평가의 경우, 탈지 밀웜 분말을 6% 첨가한 설기떡(MS-6)의 색, 맛, 향 및 전반적인 기호도 점수가 가장 높았다. 탈지 밀웜 분말을 6 % 첨가한 설기떡(MS-6)의 일반성분을 대조군과 비교한 결과, 대조군과 MS-6간에 수분함량과 조회분 함량에는 차이가 없었으나, 단백질 함량은 MS-6이 높았고 탄수화물은 대조군이 높았다. 탈지 밀웜 분말을 6 % 첨가한 설기떡(MS-6)의 분지사슬 아미노산(BCAA) 함량을 대조군과 비교한 결과, 대조군에 비해 탈지 밀웜 분말 첨가로 근육형성 기능을 하는 branched amino acids인 valine($275.8{\pm}3.41mg/100g$), leucine($414.3{\pm}5.87mg/100g$) 및 isoleucine($188.9{\pm}2.31mg/100g$)의 함량이 유의적으로 증가되었다. 이상의 결과 탈지 밀웜 분말을 6 % 첨가한 설기떡(MS-6)은 일반성분 중 단백질함량, 아미노산 중 분지사슬 아미노산(valine, leucine 및 isoleucine) 함량이 대조군에 비해 높아져 영양적 단점이 보완되어 단백질 강화식품으로의 활용가치가 높을 것으로 보여진다.

This study was performed to develop Sulgidduk prepared with different levels (0, 3, 6, 9 and 12%) of defatted mealworm powder and to evaluate the characteristics of this Sulgidduk. We performed an assessment of color values, mechanical properties, general compositions and branched amino acids of Sulgidduk prepared with different levels of defatted mealworm powder. For the color values, the lightness(L) was decreased with increased amount of defatted mealworm powder, while the redness(a) and yellowness(b) were relatively increased. For the mechanical properties, the hardness and gumminess were significantly increased according to the increased amounts of defatted mealworm powder, but the chewiness, springiness and cohesiveness showed significant differences. For the sensory evaluation, the overall quality of Sulgidduk prepared with 6% defatted mealworm powder (MS-6) was higher as compared with that of the other Sulgidduk samples. For the general composition, the moisture and crude ash contents of MS-6 did not shown differences, while the crude protein was higher than those of the control, and the carbohydrate content of the control was higher than that of the MS-6. The contents of branched amino acids (valine, leucine and isoleucine) of MS-6 were higher than those of the control. Therefore, it was concluded that MS-6 could be a protein rich food as a good source of branched amino acids such valine, leucine and isoleucine.
