Abstract

The effects of the addition of germinated whole soy flour on dough and noodle characteristics were investigated in this study. The soybeans were germinated for 12 hours at $20^{\circ}C$ and ground to 60 mesh. With increasing soybean flour addition up to $16\%$, the RVA viscograph and mixograph properties were significantly decreased both with and without the addition of $3\%$ salt(p<0.05). The width and length extensibility were increased with increasing whole soy flour addition up to $8\%$ after which they decreased. The addition of the whole soy flour turned the color of the wet and cooked noodle a little darkish and greenish yellow. The hardness and gumminess of wet noodle increased with increasing whole soy flour amount, while those of cooked noodle gradually decreased. Sensory evaluation showed that addition of tile whole soy flour significantly increased the savory flavor and yellowish color of cooked noodle.

본 연구에서는 12시간 발아시킨 신팔달 2호 콩분말을 첨가하였을 때의 반죽특성과 제면특성을 살펴보았다. 발아콩분말을 첨가한 반죽의 호화특성은 발아콩분말 첨가량이 증가할수록 호화점도가 감소하였으며 $3\%$ 소금을 첨가한 반죽에서는 발아콩분말을 $8\%$ 첨가했을때까지 점도가 높았으나 그 이후에는 소금 무첨가군보다 낮은 경향을 나타내었다. Mixograph로 측정한 반죽의 점탄성도 발아콩분말 첨가량이 증가할수록 감소하였으나 $3\%$ 소금을 첨가한 반죽이 소금 무첨가군보다 높게 나타났다. 생면의 신장도를 측정한 결과 발아콩 분말 $8\%$ 첨가군이 치고의 신장도를 나타내었으며 조리면의 무게과 부피증가율은 발아콩분말 $4\%$ 첨가군에서 가장 높았다. 조리액의 탁도는 발아콩분말 $16\%$ 첨가군이 0.57로 측정되어 고형분의 용출이 가장 많은 것으로 나타났다. 생면 제조시 발아콩분말의 영향은 첨가량이 증가할수록 L값은 지속적으로 감소하였으며 a값은 (-)값이, b값은 (+)값이 증가하여 greenish yellow의 색상을 나타내었다. 조리면의 색도는 생면보다 낮은 값을 나타내었으나 같은 경향을 보였다. 발아콩분말의 첨가량이 증가하면서 생면의 hardness와 cohesiveness, springiness, gumminess 및 brittleness는 증가하였으나 조리면에서는 hardness, gumminess 및 brittleness가 감소하였다. 조리면의 관능검사 결과 발아콩분말 첨가량이 증가할수록 고소한 맛과 냄새는 유의적으로 증가하였고 hardness와 chewiness는 첨가군간에 유의적인 차이가 없는 것으로 나탸났다.
