Abstract

In order to develop low calorie noodles, flours of Jerusalem artichoke and strong wheat were mixed with ratios of 25 : 75, 30 : 70 and 35 : 65. The substitution of wheat flour with Jerusalem artichoke powder up to 25% showed good formation of noodle stripes similar to that of wheat flour alone. The formation was effectively improved by addition of $0.5{\sim}1.0%$ solution alginate, 1.0% Fremol or mixure of 0.5% ${\alpha}-Polygel$, 0.5% Alcalin and 1.5% fremol for $25{\sim}30%$ substitution with Jerusalem articoke powder. Also addition of sodium alginate to the 30% substitution with Jerusalem artichoke powder showed the high Hunter value of Lightness and good cooking quality of noodle, relatively close to those of noodle of wheat flour alone. The dough prepared with mixed flours showed increase in cohesiveness and resilience and decrease in hardness and adhesiveness, compared to those of wheat flour. The addition of sodium alginate was very effective for increase in adhesiveness and cohesiveness. The cohesiveness of cooked noodles was increased with substitution with Jerusalem artichoke powder while sodium alginate influenced little. There is no significant difference of taste, odor, color and texture of cooked noodles between wheat flour alone and composite flours with $25{\sim}30%$ of Jerusalem artichoke and texture modifying agents. The results suggested that good quality noodles could be produced using Jerusalem artichoke powder.

저열량식품의 개발을 목적으로 돼지감자가루와 강력 밀가루를 25 : 75, 30 : 70, 35 : 65의 비율로 혼합한 복합분으로 국수를 제조한 결과 돼지감자가루를 25%까지 혼합하여 만든 국수는 밀가루와 유사한 면대형성을 보였으며 돼지감자가루를 $25{\sim}30%$혼합한 것에 $0.5{\sim}1.0%$의 sodium alginate, 1.0% Fremol 또는 0.5% ${\alpha}-Polygel+0.5%\;Alcarin+1%\;Fremol$을 첨가하면 면대형성이 효과적으로 개선되었다. 색도면에서 돼지감자가루를 30% 혼합하고 sodium alginate를 첨가하여 만든 국수의 색이 표준 밀가루국수의 색에 가장 근접하게 나타났으며 또한 조리시험에서 좋은 효과를 나타내었다. 복합분 반죽의 응집성과 탄력성은 밀가루에 비해 감소하였으나 견고성과 부착성은 증가하였다. Sodium alginate의 첨가는 부착성과 응집성의 증가에 효과적이었다. 삶은 국수에서는 복합분이 밀가루에 비하여 응집성이 증가하고 씹는감은 감소하였고 sodium alginate는 영향을 주지 않았다. 돼지감자가루를 $25{\sim}30%$ 혼합한 복합분과 이에 품질개량제를 첨가한 조리국수의 색깔, 맛, 냄새, 텍스쳐에 관한 관능검사는 순 밀가루구수와 비교하여 유의적인 차이가 없는 것으로 나타나 국수 제조 가능성이 인정되었다.
