Abstract

Wet noodles with different percentages of Curcuma Ionga L. powder(CLP) as an additive were generated and their cooking characteristics were evaluated. Wheat flour with 8% CLP had the highest water binding capacity and breakdown, while setback was reversed. Cooked noodle characteristics, weight, volume and tensile strength decreased as CLP content of wheat flour increased, but turbidity of the soup was reversed. L value of wet noodles was higher than cooked noodles, while b value, and texture of wet noodles were lower than cooked noodles. Hunter color value and texture measurements demonstrated decreasing L value, springiness and cohesiveness but increasing b value, hardness, gumminess and chewiness with increasing CLP content. In sensory evaluations, noodles made with 4% CLP were most highly preferred, while noodles made with 2% and 8% CLP were less preferred than CLP-free prepared noodles.

울금가루를 새로운 식품소재로 활용하고자 하는 연구의 일환으로 울금가루 첨가량을 달리하여 국수를 제조하고 그 품질특성을 조사하였다. 밀가루와 울금가루 혼합분의 물결합력과 breakdown은 울금가루 8% 첨가구에서 가장 높았으나, setback은 울금가루 8% 첨가구에서 가장 낮았다. 울금가루 첨가 국수의 조리 특성에서 무게, 부피 및 인장강도는 울금가루 8% 첨가구에서 가장 낮았고, 대조구에서 가장 높았으나, 탁도는 울금가루 8% 첨가구에서 가장 높았으며, 울금가루 첨가량이 증가할수록 높았다. 국수의 조리 전과 조리 후의 색도 및 물성의 변화에서 L값은 조리 전 생국수가 조리된 국수보다 높았으나, 색도의 a값 및 b값과 물성에서는 조리 전 생국수보다 조리된 국수에서 높았다. 색도의 L값과 물성의 탄력성 및응집성은 울금가루 첨가량이 증가할수록 낮아졌고, 색도의 a값 및 b값과 물성의 경도, 점착성 및 씹힘성은 울금가루 첨가량이 증가할수록 높아졌다. 울금가루 첨가량에 따른 관능검사에서 울금가루 4% 첨가구의 기호도가 가장 높았고, 울금가루 2% 및 8% 첨가구는 대조구보다 낮은 기호도를 보였다.
