Effects of Mulberry Leaves Powder on the Cooking Characteristics of Noodle

Mulberry leaves noodles were prepared with composite flour by the addition of various levels of mulberry leaves powder of 100 mesh particle site. The characteristics of cooked noodle including color, texture, cooking properties were measured, and sensory evaluation was performed. The L and a values of cooked noodle decreased as more wheat flour was substiruted with mulberry leaves powder. And the b value of noodle containing mulberry leaves powder was higher than control, but b value did not increase as the ratio of powder increased. The increase in cooking weight and volume was greater with cooked noodles of higher content of mulberry leaves powder. The turbidity of soup and eluted solid content increased as the content of powder increased, indicating higher cooking loss. There was not much difference in hardness among cooked noodles, but cohesiveness and springiness decreased as the ratio of mulberry leaves powder increased, while adhesiveness increased. The results of sensory evaluation showed that cooked noodles containing 4% and 6% mulberry leaves powder were acceptable as much as wheat four noodle in terms of color, texture, taste and flavor. But the overall acceptability of mulberry leaves noodle was lower than wheat now noodle.

뽕잎분말의 첨가가 국수의 조리특성에 미치는 영향

뽕잎분말이 국수의 제면과 조리특성에 미치는 영향을 조사하기 위해서 뽕잎분말의 첨가량을 달리한 국수를 제조한 후에 색깔, 조직, 조리특성, 관능검사를 실시한 곁과는 아래와 같다. 1. 뽕잎국수의 색깔은 뽕잎분말의 첨가량이 많을수록 어둡고 진한 녹색을 띠었으며, 이로 인해서 밝기를 나타내는 L값은 감소하였고. 녹색을 나타내는-a 값은 증가하였다. 황색을 나타내는 b값은 모든 뽕잎국수가 대조구보다는 높았으나, 2% 첨가국수에서 가장 높았고 뽕잎분말의 첨가량이 증가할수록 감소하였다. 2. 뽕잎분말의 함량이 높은 국수일수록 조리한 면의 중량과 부피가 높게 나타났으며, 조리액의 탁도나 조리손실도 증가하는 것으로 나타났다. 3. 뽕잎분말을 첨가한 국수는 대조구와 비교해서 견고성에는 별 차이가 없었으나, 응집성과 탄력성은 떨어지고 부착성은 증가하는 것으로 나타났다. 4. 관능검사 결과, 뽕잎분말을 4%와 6% 첨가한 국수는 대조구와 비교해서 색상, 조직, 맛, 향에서 비슷한 기호도를 나타내었으나, 8%와 10%는 모든 면에서 낮은 점수를 얻었다.
