Abstract

We conducted this study to investigate the quality characteristics of extruded noodles(EN) mixed with cereals. The EN were evaluated for cooking properties(weight, water absorption, volume, and turbidity), Hunter's color values, texture characteristics, and sensory characteristics. The cooked weight, water absorption, and volume of the cooked EN were significantly decreased relative to that of control noodles, whereas the turbidity increased. Hunter's color L- and b-value of EN were decreased compare with the control noodles, but a-value was increased. Hunter's color L-value of cooked EN was increased, whereas a- and b-value was increased. The texture characteristics(hardness, adhesiveness, springiness, gumminess, and chewiness) of the cooked EN-2 and EN-3 were similar to the cooked control noodles. A sensory characteristics (appearance, flavor, texture during mastication, taste, and overall quality) of EN-1 were significantly decreased relative to that of control noodles, but EN-2 and EN-3 was not different to control noodles. As the results of this study indicate that extrusion processing could be used to make the EN mixed with cereals.

본 연구에서는 잡곡을 원료로 압출성형공정을 이용하여 압출면을 제조하고 삶음 후 품질특성을 평가하였다. 잡곡 압출면의 삶음 후 중량, 수분흡수율, 부피는 각각 52.40~54.14 g, 161.74~170.16% 및 49.00~52.00 $m{\ell}$로 대조구에 비해 낮았고, 국물의 탁도는 0.60~0.87로 높게 나타났다. 삶음 전 잡곡 압출면의 색도는 대조구에 비해 L, b값은 감소하고, a값은 증가하였으며, 삶음 후 L값은 증가하고, a와 b값은 감소하였다. 잡곡 압출면 EN-2과 EN-3의 견고성, 부착성, 탄력성, 씹힘성, 검성, 응집성은 대조구와 유사한 조직감 특성을 보였다. 잡곡 압출면 EN-1의 외관, 풍미, 씹는 동안의 조직감, 맛 및 전반적인 기호도는 대조구에 비해 유의적으로(p<0.05) 낮게 평가되었지만, N-2와 EN-3은 유사한 관능특성을 보였다. 이상의 결과로부터 압출성형공정을 이용한 잡곡 압출면의 제조가 가능하며, 잡곡 압출면 제조시 녹두 첨가는 잡곡 압출면의 관능특성에 긍정적인 영향을 주는 것으로 생각된다.
