Abstract

The principal objective of this study was to assess the quality characteristics of noodles prepared at ratios of 0% (I), 1.4% (II), 2.8% (III), and 4.2% (IV) Dioscorea japonica powder, based on the wheat flour weight. The lightness of the uncooked and cooked noodles decreased significantly as the amount of Dioscorea japonica powder increased. The yellowness of the cooked noodles were reduced significantly, but the redness of all samples were significantly increased with increasing amounts of Dioscorea japonica powder. The rate of weight increase and volume increase of the noodles, as well as the density, pH, and turbidity of the soups were also assessed. The cohesiveness and gumminess of samples III and IV were significantly lower than those values in samples I and II. The results of our sensory evaluation test evidenced no significant differences in appearance and flavor among all samples. The colors of I and II were better than those of III and IV. The taste and texture scores of IV were the highest, and as a result the overall acceptability of III was most preferred.

마 분말을 밀가루 대비 0%(시료 I), 1.4%(시료 II), 2.8%(시료 III), 4.2%(시료 IV)를 대체하여 첨가하여 국수를 만들어 여러 가지 특성을 조사하였다. 생국수와 조리된 국수의 L값은 마 분말의 첨가량이 증가할수록 유의적으로 감소하였다. 조리된 국수의 b값은 마 분말의 첨가량이 늘어날수록 유의적으로 감소하였으나 a값은 네 시료 모두 유의적으로 증가하였다. 조리에 따른 국수의 무게증가율에서는 IV 시료가 가장 높았다. III, IV 시료의 부피증가율이 I, II 시료보다 더 컸다. 조리된 국수의 밀도는 시료 간에 유의적인 차이가 없었다. 국물의 pH와 탁도는 마 분말의 첨가량이 늘어남에 따라 유의적으로 증가하였다. 조리된 국수의 경도와 탄성은 시료 I이 가장 높았고 시료 II, III, IV에서 모두 유의적인 차이가 없었다. 응집성과 검성은 시료 III, IV가 I, II에 비해 유의적으로 더 작았다. 관능검사 결과 네 시료 사이에 외관과 향미의 기호도에는 유의적인 차이는 없었다. 색은 I과 II 시료가 III, IV 시료에 비해 높은 기호도를 보였다. 맛과 조직감, 종합적인 기호도에서 시료 III이 가장 선호되었다. 이로써 마 분말이 첨가된 국수의 제조를 위해서는 2.8% 정도의 마 분말을 밀가루에 대체하여 첨가하는 것이 적당할 것으로 판단되었다.
