This study was intended to make Korean type of sourdough bread using domestic wheat produced in Korea, while measuring and analyzing gluten content, pH level, TTA level and mixograph of wheat to extract the most excellent sourdough starter. Furthermore, this study also used CrumbScan to compare and analyze the properties of product as shown in making sourdough bread with the above starter. pH level ranged from 4.0 to 4.5 throughout all kinds of Korean wheat four, which were considered to be appropriately available as sourdough starter. As the result of analysis from mixogram, SF fit for making bread but korean wheat flour showed less level of mixing tolerance and content of protein, which were considered inappropriate for making bread. As the result of imaging analysis by CrumbScan, SF, KWF 5 and KWF 6 showed the higher fineness and elongation than any other kind of korean wheat flour, which were considered appropriate for making bread.

The bread qualities were analyzed objectively by using CrumbScan software. Samples were prepared at the same conditions of mixing, fermentation, and baking time except the amount of Korean wheat flour (KWF). The bread volume was increased with increasing KWF, and the maximum volume was attained in the product of 20% KWF. Although the products of 20% and 30% KWF showed the same thickness of the crust, the crust was thinner than control when KWF was added. The size (fineness) and shape (elongation) of crumb cells were larger and rounder than control due to the low degree of elasticity of the KWF-added dough. Among the samples, the product with 20% KWF showed the most even distribution of crumb cells around the sliced area. The precise determination of external and internal characteristics of the bread was possible with Crumbscan, suggesting the possibility of developing industrial standards for bread.

This study was designed to investigate the effect of Korean whole wheat flour making pan bread. Korean whole wheat flour was mixed with flour at the level of 10% (WHF10), 20% (WHF20), 30% (WHF30), 40% (WHF40) and 50% (WHF50) in order to make bread. According to mixogram, the CON (control), WHF10, WHF20, WHF30, WHF40, except WHF50 were found to be proper between 3 and 5 min. in terms of peak time. CON and WHF10 for peak value were at the level of over 60%. By increasing the ratio of Korean whole wheat flour, the pH, dough fermentation rate, volume, specific volume and moisture content were decreased, and gumminess, cohesiveness and hardness except springiness, were increased for storage days. In the crumbScan analysis, the addition of Korean whole wheat flour decreased the volume and increased the crumb fineness of pan bread. In the sensory evaluation, WHF30 showed good preference in the aspect of flavor, taste and overall acceptance, but was not significant between WHF20. CON scored the highest points in volume, specific volume, moisture content and texture, but was not significant between WHF20.

This study was designed to investigate the effect of cranberry powder making pan bread. Cranberry powder at the level of 1 % (CP1), 3% (CP3), and 5% (CP5) was mixed with flour to make the breads. According to mixograph, the control, CP1 and CP3 except CP5 were found to bo proper between 3 and 5 min. in tenn of peak time (min). All samples for peak value were at the level of over 60% It meant that all samples were proper to make bread. By increasing the ratio of cranberry powder, pH, dough fermentation rate, volume and specific volume were decreased, and adhesiveness, springiness, cohesiveness and resilience except hardness were decreased in texture profile analysis. In crumbScan analysis, the addition of cranberry powder decreased the volume and increased crumb fineness of pan bread. In sensory evaluation, CP1 and CP3 showed good preference in aspect of flavor, taste, and overall acceptance.

The purpose of this study is to investigate if Korean wheat flour(KWF) can be used a sourdough ingredient. Gluten contents, pH levels, TTA levels, fermentation rates, mixograph, crumbScan and sensory evaluation were analyzed. The pH levels of sourdough starters ranged from 4.0 to 4.5 throughout all kinds of KWF, and they proved to be available as a sourdough starter. KWF 5 and KWF 6 showed the higher fineness and elongation of crumb grain than any other kind of Korean wheat flour, which were considered appropriate for making bread. KWF 6 scored good mark in the sensory evaluation for texture of crumb and color of crust among all kinds of KWF. In conclusion, although the sourdough bread with sourdough starter SF of bread flour showed the best result in the evaluation, KWF 6 was considered as a good sourdough starter since the result was shown better than CON.

This study was conducted to examine the characteristics of bread quality as per addition rate of citrus mandarin peel powder since interests and concerns about healthy functional food have been increased in contemporary society. The result of mixogram from Mixograph showed that dough added with 3% citrus mandarin peel powder was suitable for baking quality. Stickiness of dough was decreased with addition of citrus mandarin peel powder. Compared with the controlled group, fermentation rate was decreased as the level of citrus mandarin peel powder increased while pH levels of dough and bread were significantly decreased. The TPA analysis showed that the hardness and adhesiveness levels increased as the level of citrus mandarin peel powder increased whereas springiness, cohesiveness and chewiness became decreased. Crumb fineness and elongation became higher as seen from the result of crumbScan. Volume and specific volume was decreased. The result of preference test presented that crumb color, texture, flavor and taste were the highest in the M3, which showed highest point in overall preference. In conclusion, M3 was the best in preference, taste and texture, thus determined as the optimal rate in association with the addition of citrus mandarin peel powder.

This study investigated the quality characteristics of white pan bread with banana addition. This analysis was through mixograph and stickiness of dough, fermentation rate, TPA, crumbScan image analysis, color, moisture contents and acceptance test. Mixograph peak time presented 4~5 minutes on every sample. However, CON, B10 and B20 sample presented more than 60%, and B30, B40 presented less than 60% at peak value (%). The result indicated that banana addition increased as the stickiness decreased. The fermentation rate generally increased, but the sample B40 decreased after 75 minutes. The result of crust and inside color, CON was the highest on lightness L value, B40 was the highest on both red a value and yellow b value. The result of pH showed that B40 was the lowest, and more banana addition made pH decreased. Thus, adding banana influences negatively on volume and cost of the product. The image analysis through crumbScan did not show any significant difference on crust thickness and distortion of crumb fineness. On the other hand, CON value was 774.33 that was the lowest, and B40 value was 927.66 which is the highest on the density of crumb fineness. Hardness showed a significant difference; B40 was the lowest, and Control was the highest. Moisture contents generally had a noticeable difference; CON value was the highest, and banana addition increased as the value decreased. At the result of acceptance test, one of the sensory tests, B20 showed the highest grade, and B40 showed the worst. Based on the above results of characteristic difference, banana addition could influence volume of the bread negatively.

This study was to investigate the quality characteristics of sourdough bread made with 4 kinds of kamut sour starter. Kamut sour starters were made according to dough yield of sour starter and yeast adding on sour starter. We exmanined pH level, fermentation rate, specific volume, CrumbScan, moisture content, color value, texture analyzer, shelf-life test and sensory evaluation for observing quality characteristics of sourdough bread. From the results of pH measurement, kamut sourdough breads had lower pH value in dough and crumb pH than CON. In the experiment of dough's fermentation rate, CON had the rapidest fermentation rate among the samples initially, but the experimental groups also expanded as much as CON grew in spite of its slow fermentation. Specific volume and CrumbScan results suggested that CON had the largest volume. In addition, CM and TM had smaller volume than Pool and Biga. The sample that had the highest moisture content was Pool because its sour starter had the most amount of water. In color value test, CON had lighter crumb and crust color than other specimens. As a result of the TPA and shelf-life tests, CON had the softest hardness after 24 hours. However, Pool had similar hardness with CON after 72 hours. The result of the acceptance test of sourdough breads indicated that people prefered Pool and Biga to TM and CM. Difference test showed similar results with prior experiments. As the final outcome, Poolish was chosen as the optimal formula for kamut sour starter.
