In this study, domestic wheat flour was used to develop a native sourdough suitable for the Korean environment, in an attempt to replace the sourdough starter that are currently available in local markets and used to prepare sourdough breads. Nine kinds of domestic wheat flour (available at local market) were examined and to characterized according to their general ingredients, gluten contents, colorimetry data and mixograph measurement. In addition, the flour were used to make sourdough starters that were assessed for pH, TTA, and fermentation rate from which an optimal sourdough starter could be chosen. This study also compared the product characteristics breads prepared from the with one another by adding extracted sourdough starters. In order to analyze the quality characteristics of the breads, a comparative analysis was conducted through on data for dough fermentation rate, specific volume, texture analyses, colorimetry, water activity and sensory tests. According to the results, the sourdough starters KWF 3, KWF 4 and KWF 5 scored well in evaluations for gluten content, wheat flour characteristics and pH, and were deemed the most optimal starters. To characterize the sourdough breads prepared from KWF 3, KWF 4, and KWF 5, their quality characteristics were analyzed and then compared to those sourdough bread (control group) prepared using a sourdough starter made from imported wheat flour. According to the comparative analysis of the quality characteristics, KWF 4 had the largest volume and specific volume, but had the lowest textural hardness, indicating the softest texture of overall. According to sensory tests, the bread prepared from KWF 4 was significantly more preferred than the other specimens.
