Quality Characteristics of White Pan Bread Using Whole Wheat (Triticum aestivum) Flour

Abstract

Five-color bread was prepared by adding herb powder to Korean whole wheat triticum aestivum flour and the quality of baking was analyzed. The pH of the control bread was 6.15±0.12 while that of the whole wheat flour test group was 6.35±0.11, 6.29±0.12, 6.36±0.12, 6.19±0.11, and 6.01±0.13, respectively. The L value of the control bread was 67.78±0.03 and that of the whole wheat flour test group was 69.66±0.02, 60.01±0.12, 64.23±0.01, 63.34±0.01, and 61.64±0.04, respectively. The water activity was slightly increased at 2 days of storage due to the difference in water absorption and water retention. However, on the third day, the water transfer phenomenon in the bread showed water activity decrease in all wheat flour test groups. On the 1st day of the whole wheat flour test bread, the hardness values were 186.86±4.81, 165.89±3.73, 189.71±3.32, 198.38±2.19, and 184.29±3.40 g/cm2, respectively, and that of the control group was 138.84±3.72 g/cm2. The hardness of the control group and the whole wheat flour test group showed a significant difference. The internal structure of the bread in the whole wheat flour test group (100x, 500x) was not smoother than the control’s. The swelling degree of the starch particles and the cracking of the crumbs were confirmed by the adding of five-colored herbs to whole wheat flour.
