발아현미분을 첨가한 국수의 제조특성

국문 초록 (Abstract)

발아현미 가루 첨가가 국수제조에 미치는 영향에 대하여 특성을 파악하고 기호성을 고려한 최적의 배합비율을 조사하였다. 발아현미의 불용성 식이섬유 함량은 5.1%, 수용성식이섬유의 함량은 4.2%이었다. 발아현미분을 첨가한 반죽의 Farinogram 흡수율(water absorption)은 대조구(100% 밀가루)보다 낮아지는 결과를 보였고, 반죽형성시간(development time)은 대조구보다 빨랐다. 안정도(stability)의 경우는 발아현미분의 첨가량이 증가할수록 낮아지는 결과를 보였으며, 약화도(weakness)는 증가하여 글루텐 구조력이 저하되는 것으로 나타났다. 발아현미분을 첨가한 국수의 색도는 실험결과 대조군과 비교하여 L<SUP>*</SUP>값은 낮고, a<SUP>*</SUP>값은 높게 나타나는 결과를 보였다. 이는 대조군에 비하여 발아현미분은 도정되지 않은 껍질층의 혼입양이 많은 것에서 그 이유를 찾아볼 수 있을 것으로 사료된다. 발아현미분을 5~20% 첨가하여 제조한 조리면의 부피증가율은 큰 차이를 나타내지 않았으며, 조리 후 중량 역시 감소하였으나 국물의 탁도는 대조군에 비해서 증가하는 경향을 보였다. 조리면의 cutting force는 발아현미분의 첨가량 증가에 따라 약간의 감소는 보였으나 큰 차이는 나타내지 않았다. 발아현미분을 첨가하여 관능검사를 실험한 결과, 발아현미분을 10% 첨가하였을 경우 향, 색, 맛, 모양 및 전체적인 기호도에서 대조구와 큰 차이를 나타내지 않았다.

다국어 초록 (Multilingual Abstract)

The effects of germinated brown rice flour on the quality characteristics of white wheat flour noodles were investigated. The insoluble dietary fiber and soluble dietary fiber content of germinated brown rice flour were 5.1% and 4.2%, respectively. Water absorption, development time, and stability of farinogram decreased when germinated brown rice flour was added to white wheat flour. Brightness (L<SUP>*</SUP>) decreased, but redness (a<SUP>*</SUP>) increased in noodles made from germinated brown rice. Volume of cooked noodles did not change upon addition of germinated brown rice flour, but weight of cooked noodles decreased and the turbidity of cooked water increased. The cutting force of cooked noodles did not change upon addition of germinated rice flour. Addition of 10% germinated brown rice flour to white wheat flour did not have any effects on flavor, color, taste, appearance, and overall acceptability in sensory evaluation.
