Abstract

This study investigated the quality characteristics of noodles containing roasted Liriopis tuber. Roasted Liriopis tuber powder (LTP) was added in different amounts based on wheat flour (1%, 3%, 5%, 7% and 9%). Cooked noodles containing LTP exhibited significantly lower values for weight, volume, and water absorption; in contrast, higher values were exhibited for turbidity. The Hunter L value (for lightness) of uncooked and cooked noodles decreased but the a value (for redness) and b value (for yellowness) increased with the addition of Liriopis tuber. Textural properties (springiness, cohesiveness, chewiness, and brittleness) measured with a texture analyzer significantly decreased with the addition of Liriopis tuber. From the sensory evaluation results, noodle containing 7% Liriopis tuber was considered the best. To improve the quality of noodle containing 7% LTP, activated gluten was added at different percentages of flour (1%, 2%, 3%, 4% and 5%). Cooked noodles containing activated gluten exhibited significantly higher values for weight, volume, and water absorption; in contrast, lower values for turbidity were exhibited. In addition, the textural properties significantly increased with the addition of activated gluten. From the sensory evaluation results, noodle containing 3% activated gluten was considered the best. In conclusion, noodle with 7% LTP and 3% activated gluten exhibited the most desirable qualities.

본 연구는 볶음 처리를 한 맥문동 첨가 국수의 제면적성 및 품질특성을 살펴보기 위하여 생면을 제조한 후 최적의 맥문동 첨가비율을 밝히고자 하였다. 볶음 처리를 한 맥문동 분말을 밀가루 중량 대비 1%, 3%, 5%, 7% 및 9%를 첨가하여 제조한 국수의 제면적성과 품질특성을 조사하였다. 맥문동 분말을 첨가하여 제조한 국수의 조리 후 중량과 부피 및 수분흡수율은 맥문동 첨가량이 증가할수록 유의적으로 감소하였으며, 탁도는 증가하였다. 색도는 생면과 조리면 모두 맥문동 첨가량이 증가할수록 대조구에 비해 L값은 감소하였으며 a, b값은 증가하였다. 탄력성, 응집성, 씹힘성, 부서짐성 등의 조직감은 모두 맥문동 첨가량이 증가할수록 감소하는 경향을 보였다. 관능검사 결과 맥문동 분말 7% 첨가국수가 가장 좋은 것으로 나타났다. 하지만 맥문동 첨가량이 증가할수록 고형분의 용출로 인한 탁도 증가와 조직감의 저하가 나타났으므로 이를 보완하기 위해 품질개량제인 활성글루텐을 첨가하여 품질 향상을 시도하였다. 품질특성 실험결과 기능성과 관능 등에서 가장 적절한 것으로 선정된 맥문동 7% 첨가군에 활성글루텐 1%, 2%, 3%, 4% 및 5%를 첨가하여 품질특성을 살펴보았다. 이 결과 조리 후 중량, 부피, 수분흡수율은 글루텐 첨가량과 비례하여 증가하였으며, 탁도는 감소하였다. 탄력성, 응집성, 씹힘성, 부서짐성 등의 조직감도 모두 향상되었다. 관능검사 결과 활성글루텐 3% 첨가구가 관능적으로 가장 좋은 것으로 나타났다. 결과적으로 맥문동 분말 7%에 활성글루텐 3%를 첨가하였을 때 가장 우수한 맥문동 첨가 국수를 제조할 수 있는 것으로 나타났다.
