  • Quality characteristics and functional properties of Korean wheat noodle with brassica oleracea L. powder were investigated to develop health promoting and high quality product. Brassica oleracea L. powder was extracted with water and $70\%$ ethanol, and the extracts were tested its electron donating ability (EDA) and nitrite scavenging ability (NSA). Quality characteristics of the noodle were evaluated by its color, flavor, moisture, softness, texture and taste evaluation. Microbiological Quality was also tested counting total viable cells. EDA was highest at 1000 ppm of both water extract ($64\%$ of EDA) and ethanol extract ($76\%$ of EDA). NSA was highest pH 1.2 of both water extract ($42\%$ of NSA) and ethanol extract ($46\%$ of NSA). In antimicrobial activity test, Korean wheat noodle with $3\%$ pine pollen powder displayed $0.5{\~}1$ log cycle of total viable cell counts lower than that of control at 5 days of storage. Sensory evaluation of Korean wheat dried and cooked noodles with $3\%$ Brassica oleracea L. powder showed significantly higher scores in overall.

  • This study introduces the addition of wheat fiber, oat fiber, and inulin to Chinese-style sausages, in amounts of 3.5% and 7%, respectively. Researchers used analysis of general composition and texture properties, and sensory evaluation to assess the influence of these three types of dietary fiber on the quality and palatability of Chinese-style sausages. Results showed that the type and amount of dietary fiber introduced did not significantly influence the general composition, color, and total plate count of sausages. However, the addition of wheat fiber and oat fiber significantly hardened the texture of Chinese-style sausages (p<0.05). A greater amount of dietary fiber added implied a harder texture. Added inulin did not influence the texture of Chinese-style sausages (p>0.05). Results of product assessment showed that, aside from sausages with 7% wheat fiber scoring less than 6 points (on a 9-point scale) in terms of overall acceptability, the other groups of Chinese-style sausages scored over 6 points. Judges preferred the sausage groups with 3.5% added oat and wheat fiber. This study demonstrates that adding fiber to Chinese-style sausages to increase the amount of dietary fiber is feasible.

  • The various conditions of substituting wheat gluten for the bean, one of the raw materials for soy sauce manufacture, was studied by measuring the activities of the amylase and proteolytic enzyme of koji. It was found that substitute wheat gluten for up to 60% of bean content (30% of the total bran and wheat content) yielded good quality of soy sauce. By using more than 30% of wheat gluten the availability of nitrogen of raw materials was decreased. This was attributed to the low enzyme activity in koji containing more than 30% wheat gluten.

  • 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.

  • The purpose of this study is to investigate the sensory characteristics and preference of Spelt white bread and to examine its market potential. For this purpose, the sensory characteristics of Spelt flour dough was analyzed and a questionnaire survey was conducted on the general public to grasp the preference and repurchase intention of Spelt bread. As a result of this study, the sensory characteristics of Spelt wheat dough showed that the fermentation rate was slightly higher than that of general wheat flour and the Spelt flour dough was more slightly acidic than that of general wheat flour. The result of this survey showed that Spelt flour bread had a comparative advantage in terms of digestibility, flavor and overall favorability compared to general wheat flour. For the repurchase intentions for Spelt flour bread, it was found that the intentions to buy it for health and as gifts was high. Based on this research, I expect that the studies about marketing strategy with Spelt flour bread will be done along with the development of various products.

  • Fusarium head blight (FHB), also known as scab, caused mainly by Fusarium graminearum is a devastating disease of wheat in regions that are warm and humid during flowering. In addition to significant yield and quality losses, the mycotoxin deoxynivalenol produced by the pathogen in infected wheat kernels is a serious problem for food and feed safety. Twenty- three Korean cultivars and "Sumai 3", which is a FHB-resistant Chinese cultivar were tested for Type I, Type II resistances of FHB. Three cultivars were identified as resistant in Type I assessment, and two cultivars were resistant in Type II assessment. Genetic variation and relationship among the cultivars were evaluated on the basis of 11 Simple Sequence Repeat (SSR) and 29 Sequence Tagged Site (STS) markers that were linked to FHB resistance Quantitative Trait Loci (QTL) on chromosome 3BS. One SSR and 7 STS markers detected polymorphisms. Especially, using a STS marker (XSTS3B-57), 32.4% of the variation for Type II FHB resistance could be explained. Genetic relationship among Korean wheat cultivars was generally consistent with their released year. These markers on chromosome 3BS have the potential for accelerating the development of Korean wheat cultivars with improved Fusarium head blight resistance through the use of marker-assisted selection.

  • To develop dough methods for improving bread making properties of Korean wheat flour, straight dough methods (SDM) and dough and sponge methods (DSM) were applied. The bread making properties such as weight of bread, specific volume, baking loss, crumb color, and texture were analyzed. In comparison of flour properties between Korean wheat flour and imported wheat flour by Farinograph, Korean wheat flour showed less gluten network form ability than imported wheat flour. The dough making method affected bread quality such as weight of bread, specific volume, and baking loss. SDM had a more desirable effect on bread quality. Crumb color was lighter in bread made with Korean wheat flour compared to imported wheat flour, whereas dough making method did not affect crumb color. In consumer acceptance analysis, bread made by DSM showed higher consumer acceptance than that made by SDM. Regarding physicochemical changes during storage, bread made by SDM using Korean wheat flour showed higher chewiness, brittleness, and hardness than that made by imported wheat flour. However, bread made by DSM showed similar chewiness as bread made by SDM using imported wheat flour. The bread making properties of bread made by DSM is improved versus that of bread made with Korean wheat flour.

  • The aim of this study was to investigate the quality characteristics of sponge cakes with added rice flour produced by a modified genoise method to prevent volume reduction. A control group and experimental group I were prepared by the genoise method and experimental groups II, III, and IV were produced by a modified genoise method in which they were mixed with wheat flour and water to a make paste to form gluten for 3, 6, and 9 minutes, respectively. One third of the wheat flour in all experimental groups was replaced by rice flour. The control and experimental groups were compared in terms of quality characteristics, including batter specific gravity, volume, color, textural characteristics, and sensory qualities, to determine the optimal pasting time for wheat flour in the formulation. The specific gravity of the experimental groups was higher than that of the control and decreased with increasing wheat flour pasting time. The volume of experimental group I was lower than that of the control group, and the volume values of experimental groups III and IV, made by the modified genoise method, were higher than that of the control group. $dL^*$ and $db^*$values for the crust and inside of the cake were lower in the experimental groups than in the control. The $dL^*$ value, indicating brightness, increased as pasting time increased. The hardness values of experimental groups I and IV were higher than that of the control whereas experimental groups II and III had lower hardness values. Chewiness was higher in the control group, as well as experimental groups I and IV than in the experimental groups II and III. The gumminess of experimental group IV was highest. Cohesiveness decreased by adding rice flour to the sponge cake. Sensory attributes of cell uniformity, tenderness, moistness, taste, and overall acceptability had the highest scores in experimental group III. Based on these results, we conclude that the quality of sponge cake containing one third of the wheat flour replaced by rice flour is best with 6 minutes pasting of the wheat flour to form gluten.

  • Studies to obtain a fundamental data to improve the quantity and quality of wheat protein and to select the excellent breeding materials suitable for various uses of it were performed on the focuses of protein content, amino acid composition, and its related quality. The range of seed protein content of crossing block consisted with 319 varieties or lines was from 9.9% to 17.6% with the average of 13.2%. The minimum protein content was showed by Wonkwang, and the maximum by Chungnamjaerae and Suwon 210. Among the Korean native varieties or breeding lines of crossing block, at least twelve lines or varieties were selected as the high-protein wheats. In the effects of environmental conditions, the variations of protein content by cultivating locations and year were showed out to be up to 3.6%, and 3.3%, respectively. But the varietal characteristics of wheat protein were seemed to remain constantly. In the results of amino acid analysis, those related with bread quality, except proline were improved with the increase of seed protein. But the improvement of nutritional quality did not agree with the protein content increase of seed. The total content of amino acid essential to adults was very low with 266.6-273.3mg per one gram of protein compare to the 350mg (free from the amino acid of tryptophan) recommended by FAO/WHO. Especially the limiting amino acid such as methionine, lysine and threonine were critically deficient. The correlation between protein contents and sedimentation values was obtained r=0.656$\^$**/ of average notwithstanding widly different environmental conditions, and in some condition the value was obained about to r=0.956$\^$**/.
