Sažetak
The appropriateness of a simple colorimetric method for damaged starch determination in wheat flour was tested in relation to the possibility of use of this method to predict farinograph absorption. The investigation of the influence of damaged starch and protein on farinograph absorption showed dominant influence of thus determined starch on absorption, especially in samples having a small range of protein content. Consequently, partial regression equations for predicting od farinograph absorption on the basis of damaged starch content for high-protein and low-protein samples were calculated. Predicted absorption agreed well (r=0.979) with actual absorption, what proved that simple method to be good enough for determination of damaged starch in flour and prediction of farinograph absorption.
