|
Addition of whole soy flour(WSF) to wheat flour(WF) was studies for its effects on dough and noodle characteristics. The WF used was medium grade of strength and WSF was a fine flour of 350 mesh. The addition ratio of WSF to. n was up to 20%. The dough properties and textural properties of wet and cooked noodles were measured with using Farinograph, Amylograph and Rheometer. Farinogram data showed the minimum dough development time and stability at 6% addition of WSF. Amylograph data of initial pasting temperature and time were increased while the maximum and final viscosity and setback were decreased as the WSF added more to W The initial pasting temperature of 2.0∼6.0% WSF added flour were comparable to 100% WF eventhough viscosity was almost half of WF. The water absorption capacity was increased from 81.6% to 92.3% at 6.0% WSF and then decreased as the addition ratio of WSF increased. The extensibility of dough showed a maximal value at 8.0% WSF addition. Strengthness and hardness of wet and cooked noodle were increased to the heighest measurement as the WSF added up to 6.0% followed by a steady decrease thereafter. It was also found that WSF addition resulted an increase in adhesiveness of wet noodle and decrease in hardness and strengthness of cooked noodle.
