Abstract

The peak time, peak height, width at peak, and the width at 8 min of Mixograph increased as the amount of sodium chloride in yellow alkaline noodle sheet was increased. The peak time of the Mixograph duration increased almost twice when 0.5% sodium carbonate was added to yellow alkaline noodle sheet, but decreased when the amount of sodium carbonate was above 0.5%. The peak height decreased as the amount of sodium carbonate increased. Protein content and sedimentation values showed positive correlations with the Mixograph peak height, width at peak, and width at 8min. The pasting temperature, peak viscosity, minimum viscosity, and final viscosity increased as the amount of sodium chloride in yellow alkaline noodle sheets was increased for all wheat flours. The peak viscosity, minimum viscosity, and final viscosity also increased as the amount of sodium carbonate increased. The pasting temperature showed a positive correlation with the water retention capacity and the alkaline water retention capacity.

밀가루에 소금을 0, 2 및 4%를 첨가하였을 경우, Mixograph의 peak time은 밀가루의 종류에 관계없이 소금 첨가량이 증가함에 따라서 증가함을 알 수 있었으나 박력분의 경우에는 유의적인 차이를 나타내지는 않았다. Peak height와 width at peak도 소금 첨가량이 증가함에 따라 증가하는 경향을 나타내었으나 강력분과 중력분에서는 유의적인 차이를 나타내지 않았다. Width at 8 min의 경우에는 모든 밀가루에서 소금 첨가량이 증가함에 따라 증가하는 경향을 나타내었다. Sodium carbonate를 0, 0.5, 1.0 및 1.5의 농도로 밀가루에 첨가하여 Mixograph 특성을 관찰한 결과 밀가루의 종류에 관계없이 0.5% 첨가 시 peak time이 거의 2배정도 증가하였다가 그 보다 높은 농도에서는 다시 감소된 반면, peak height는 sodium carbonate 첨가량이 증가함에 따라서 감소하는 경향을 보였다. Mixograph peak time과 단백질 함량 및 침전가와는 유의적인 상관이 없었으나, peak height, width at peak 및 width at 8min과는 모두 정의 상관관계를 보여 주었다. 반죽의 초기호화온도, 최고점도, 최소점도, 최종점도는 밀가루의 종류에 관계없이 소금의 첨가량이 증가함에 따라 증가하는 경향을 나타내었으며, 최고점도, 최소점도 및 최종점도는 모든 밀가루에서 sodium carbonate 첨가량이 증가함에 따라서 유의적으로 증가하는 경향을 보였다. 초기호화온도와 보수율 및 알칼리수 흡수율과는 정의 상관이 있었으나, 보수율과 최고점도, 최소점도 및 최종점도와는 모두 부의 상관관계를 보여 주었다.
