No significant differences were found among the treatments with respect to volume. moisture content, or crumb color. Loaves baked with the high-protein flour had significantly darker crust colors. High-protein loaves were significantly less tender. The sensory panel found no significant differences in crumb color t aroma, compressibility, mouth feel, moistness, flavor, or overall aftertaste. The panel did find that high-protein loaves were significantly darker in crust color, and loaves baked with high-protein flour and ascorbic acid had significantly larger cell sizes and less uniform cell structures.
