Abstract

The bread-making quality of two domestic flours, Hokushin and Haruyutaka, blended with Victoria INTA, an ES flour, and Harunoakebono, domestic strong flour, was investigated. The baking quality of Hokushin, representative middle-strong flour in Hokkaido, and Haruyutaka, semi-strong flour with preharvest sprouting damage, which is unsuitable domestic flours for bread production, were both improved by blending with Victoria INTA. The results were as follows : (1) With an appropriate blend of ES flour, it was proven that domestic flours with poor bread making quality could be improved and given properties for bread making that are generally attributed to foreign hard flours. (2) The estimation of specific loaf volume of bread made from blends of the flours in this experiment was possible with the following multiple-regressive equation ;X1=0.157 X2+0.251 X3+ 2.38 (X1 : specific loaf volume (ml/g); X2 : protein content of flour (%), X3 : breaking force of dough (N)). (3) Through analysis by the use of this equation, it was proven that the improvements of bread making quality by blending poor domestic flours with ES flour were principally due to the progress of physical property of the dough, an increase in the breaking force of the dough.
