Abstract

The purpose of study was to evaluate quality, physicochemical and sensory characteristics of acorn Sulgidduk by addition of acorn powder. Acorn Sulgidduk was processed rice powder which added 0, 5, 10, 15, and 20% of acorn powder. The moisture, crude lipid, and crude ash contents of Sulgidduk added with acorn powder was increased by addition amount of acorn powder, but carbohydrate and crude protein contents were decreased. By addition amount of acorn powder, soluble protein content of Sulgidduk were increased, but reducing sugar content were decreased. The L values of Sulgidduk were decreased by addition amount of acorn powder, but increased the a and b values. The hardness, adhesiveness, cohesiveness, springness and chewiness were decreased by addition amount of acorn powder. The sensory test of Sulgidduk added 10% of acorn powder showed the best score in overall preference. Therefore, these results suggested that Sulgidduk added 10% of acorn powder could be applied for produce of acorn Sulgidduk.

본 연구는 쌀가루 대비 도토리 분말의 첨가량을 0%, 5%, 10%, 15%, 20%로 설기떡을 제조한 후, 일반성분 함량, 수용성 단백질, 환원당, 색도, 조직감, 관능검사 등을 실시하여 도토리 분말을 첨가한 설기떡의 품질특성을 연구하였다. 일반성분을 분석한 결과, 수분함량은 40.15~44.42%로 도토리 분말의 첨가량이 증가할수록 수분함량은 증가함을 보였고, 탄수화물 및 조단백질의 함량은 도토리 분말 첨가량이 증가할수록 감소함을 보였으며, 조지방 및 조회분 함량은 도토리 분말의 첨가량이 증가할수록 증가함을 보였다. 수용성 단백질 함량은 0.10~0.81 g/100 g으로 도토리 분말 무첨가구에 비해 도토리 분말 첨가량이 증가할수록 수용성 단백질 함량도 증가함을 보였고, 환원당 함량은 도토리 분말 무첨가구에서 가장 높았고, 도토리 분말 첨가량이 증가할수록 환원당 함량은 감소함을 보였다. 색도측정 결과 L값은 54.13~36.33으로 도토리 분말 첨가량이 증가할수록 명도 값이 감소하는 것으로 나타났고, 적색도를 나타내는 a값과 황색도 b값은 도토리 분말을 첨가할수록 증가하는 경향을 보였다. 조직감 측정 결과, 경도 및 씹힘성은 도토리 분말 첨가량이 증가할수록 감소하는 경향을 보였다. 관능검사결과, 색은 도토리 분말 15% 첨가한 설기떡이 가장 기호도가 높았고, 맛과 향, 질감, 전반적인 기호도에서는 도토리 분말 10% 첨가한 설기떡에서 가장 높았으며, 15% > 5% > 0% > 20% 순으로 평가되었다. 따라서 도토리 분말 10% 첨가한 설기떡이 전반적인 관능평가에서 다른 첨가구에 비해 높게 평가되었으며, 설기떡 제조시 기호도 향상을 나타낼 수 있을 것으로 판단되며, 향후 다양한 제품에 도토리 분말을 활용할 수 있을 것으로 생각된다.
