Abstract

|
The rheological properties of various flour blends of HRW-WW and DNS-WW having protein contents of 9.12∼9.78% in the presence or absence of salt and alkaline reagent (an equal mixture of Na₂CO₃ and K₂CO₃) were studied. The farinograph absorptions of HRW-WW and DNS-WW blends was increased by 1% and 0.6%, respectively, with increasing protein content by 0.33%. Salt (1.7%) decreased the absorption by 1% regardless protein contents. Alkaline reagent (0.17%) or a combination of salt and alkaline reagent had no effect on absorption of flours, indicating that the effect of salt on decreasing absorption is masked by alkaline reagent. The protein content of the flour in the presence or absence of salt, alkaline reagent or both showed a highly positive correlation with all reference points of farinograph and extensograph, but the peak viscosity of amylograph was negatively correlated with protein content only in the presence of salt, alkaline reagent or both.
