Abstract

This study was conducted to evaluate quality characteristics of noodles when different concentrations of chlorella extract powder were added to the wheat flour. The characteristics of noodle including cooking properties, color, mechanical texture properties, and sensory properties were determined. The noodles containing chlorella extract powder exhibited higher values in cooked weight, volume, moisture absorption, and cooking loss. When the amount of chlorella extract powder increased, the Hunter L(lightness) value, a(redness) value of cooked noodles decreased but b(yellowness) value increased. From the textural properties measured by texture analyzer, the noodles with chlorella extract powder were significantly lower in hardness, cohesiveness, springiness, gumminess, and chewiness than those of 100％ wheat noodle. The results of sensory evaluation of cooked noodles containing chlorella extract powder indicated that the cooked noodle with 1.5％ chlorella extract powder showed the highest value. Based on cooking properties and sensory evaluation, chlorella extract powder up to 1.5％ could be substituted for wheat flour to improve the noodle quality.

생리적 활성이 높은 클로렐라 추출물을 효율적으로 활용하기 위한 방안으로 클로렐라 추출물 분말을 0.5％, 1.0％, 1.5％, 2.0％ 수준으로 첨가하여 제조한 생국수의 품질 특성에 관하여 조사하였다. 클로렐라 추출물 분말을 첨가한 국수는 조리시의 중량, 부피, 함수율, 고형분 용출량이 대조구보다 높게 나타났다. 색도는 클로렐라 추출물 분말 첨가량이 증가할수록 L값과 a값은 감소되었고 b값은 증가하였으며 조리하였을 때 L, a, b값이 모두 감소하는 경향을 보였다. 클로렐라 추출물을 첨가한 국수의 조리 후 텍스쳐에서 경도, 응집성, 탄성, 점성, 씹힘성은 대조구에 비해 낮은 값을 나타내었다. 관능 검사 결과 클로렐라 추출물 1.5％ 첨가구에서 맛, 텍스쳐, 후미, 전체적인 기호도가 가장 좋게 평가되었고, 색깔과 향은 대조구와 유의적인 차이를 나타내지 않았다. 이상의 결과를 보면 클로렐라 추출물 분말을 1.5％첨가함으로써 품질과 관능성이 향상된 생국수 제조가 가능함을 알 수 있었다.
