The bread-baking properties of mixed naked barley/wheat flour blends with various food additives were investigated in the study, and changes of loaf volume of mixed naked barley/wheat flour blends prepared by lactic acid method were observed. Addition of egg yolk, soybean flour, gluten, C.M.C. and ascorbic acid were levels of 7%, 10%, 4% ,1% and 100 ppm, respectively. The addition of these food additives to 50% barley/50% wheat flour blends yieled an increase in loaf volume. Specific loaf volumes of 50% barley/50% wheat flour blend with egg yolk, soybean flour, gluten, C.M.C. and ascorbic acid were 2.85, 2.04, 2.69, 2.77, 2.56 and 2.56 ml/g bread, respectively. As the replacement percentages of wheat flour increased, the effect of food additives on loaf volume increased. In particular, the specific loaf volume of 30% barley flour/70% wheat flour blend was similar to that of 100% wheat flour bread.
