Oat flour was purchased and investigated for quality characteristics of oat bread. Antioxidant and flour pasting properties of oat flour, and water content, weight, volume, Hunter color value, texture of bread were measured. DPPH radical scavenging capacity (%) of oat extract was 68.49%. Pasting temperature of oat flour ranged between $66.60^{\circ}C$ and $70.93^{\circ}C$. Flour pasting properties of sample added with 10 and 30% oat flour was shown similar results compared with wheat flour. Final viscosity of sample was increased by adding concentration of oat flour (up to 311.65 RVA). Water content (%) of bread was shown increasing trend by adding oat flour. Weight of bread loaf with 100% oat flour was shown higher score than other samples. Volume of loaf by adding oat flour of 10, 30, and 50 % ratio was 550, 450, and 388 mL, respectively. The Hunter color $L^*$ values of bread by adding oat flour was dark compared with wheat bread. Color value of bread added 10% oat flour was similar results with $L^*$ values of bread with wheat flour. The bread added with 20 and 30% oat flours had the higher hardness, gumminess, and chewiness compared with other samples. Cohesiveness of the bread with wheat flour showed higher than that of bread added with oat flour and increased by storage period. The growth of total viable cell was inhibited depending on the concentration of oat flour during storage.

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.

For high quality bread wheat production in Korea, it is necessary to develop optimal nitrogen (N) fertilizer methods. For optimal N fertilizer, we evaluated the alteration of growth, yield, yield components and end-use qualities according to the treatment of N fertilizer amounts and timings at heading stages. Growth, yield, yield components, and end-use quality weren't altered by various timings of N fertilizer treatment conditions whereas, 1,000 grain weight and lodging degree was increased by increasing amounts of N fertilizer treatment conditions at 7 days after heading (7 DAH). Especially, lodging degree was significantly increased by 6kg/10a of N fertilizer treatment conditions at 7 DAH. The flour protein contents increased by various amounts of N fertilizer treatment conditions. However, SDS-sedimentation and bread loaf volumes were decreased by exceeding 6kg/10a of N fertilizer treatment conditions at 7 DAH. When considering the quality of bread, 6kg/10a N fertilizer treatment is best, but 3kg/10a N fertilizer treatment is more suitable for both quality and lodging at 7 DAH. Therefore, it is preferable to fertilize 3kg/10a of nitrogen at 7 DAH in addition to standard fertilizer when cultivate bread wheat.

Rheological properties of the dough made from milled wheat products of various particle size, i.e., wheat shorts, girls and flour, and their effect on the loaf-volume potential of whole wheat bread were investigated in this study. One Korean wheat variety 'Cho-Kwang' was tested for suitability in whole wheat bread. The percent ash and protein content of the milled wheat products were 2.3% and 13.7% respectively. Ranges of 7.3, 5.6 and 4.8 mixograph peak-height were observed in Fraction 1(wheat flours), Fraction 2 (wheat girts) and Fraction 3(wheat shorts), respectively. Dought stability of Fraction 1 did not decreased appreciably as compared to that of commercial first grade baker's flour. Bread-baking test employing a standard formula showed that the wheat grits (0.2-0.5 mm in diameter) appeared to be the limit beyond which a rapid decrease in loaf-volume potential was noted. Optimum loaf volume and crumb characteristics were obtained in 80% wheat grits/20% wheat flour blend.

Bread baking parameters and relationships between bread baking properties and flour characteristics were evaluated for two years, 1997 and 1998, and at two locations, Suwon and Deokso, with Korean winter wheat cultivars and lines. Among the bread baking parameters, lightness of crumb grain showed differences between years. No significant differences were found in dough mixing time, bread loaf volume, crumb grain score or firmness. Keumkangmil, Suwon 278 and Tapdongmil showed higher bread loaf volume, good structure of crumb grain and softer crumb firmness. However, compared to commercial flours for baking, cultivar means averaged over years and locations of nineteen Korean winter wheats showed poor bread baking quality because of low protein content and unsuitable protein quality. Protein content and flour swelling volume showed better relationships with the bread baking parameters than other flour characteristics. Friabilin-absence lines showed softer crumb firmness than those of friabilin-presence lines.

The effects of defatted soy flour on the physicochemical characteristics of dough and bread-making properties were studied with sodium stearyl lactylate(SSL) as an emulsifier. Defatted soy flour was added to the wheat flour at the level of 0$\sim$12%. The emulsifier was added to the wheat flour-defatted soy flour blends at the level of 0.5 and 2%. Set-back and consistency in amylogram were significantly decreased as the level of soy flour was increased. On comparison with control, the bread made from defatted soy flour especially had less specific loaf volume. The specific loaf volume of wheat flour-defatted soy flour bread prepared with 0.5$\sim$2% SSL was better than that without SSL. Decrease of L value (lightness) of crust color and decrease of L value of crumb color were shown with the increase of defatted soy flour. From the result of sensory evaluation, wheat flour-defatted soy flour bread containing up to 6% defatted soy flour with 1.0% SSL were rated as high quality. Most of texture parameters of bread increased with the increase of defatted soy flour and decreased with increase of SSL. Considering the volume and sensory characteristics of bread, bread prepared with 6% defatted soy flour and 1% SSL was regarded as highly acceptable.

The primary objective of this study was tested the baking properties of Korean wheat. In test results, the wheat which was harvested from all over the Korea, not suitable for making bread and cake products. However, some of possibilities to make bread were found by using vital gluten as well as additives. Out of Korean wheat classes, the Tapdong wheat showed good properties for bread making, and it is recommended to develope it as bread making wheat by segregating from other classes in seeding and harvesting.

Wheat bran, a milling by-product of domestic wheat grains, containing approximately 42% of the total dietary fiber, was tested for the effects on bread-making properties. The amylograph peak viscosity and set bark values considerably decreased with increasing levels $(0{\sim}30%)$ of wheat bran. Adding wheat bran somewhat increased water absorption and showed no consistent effect on mixing time. Yeast-leavened breads were baked with wheat flour with up to 30% of the flour substituted with domestic wheat bran. Adding domestic wheat bran exerted detrimental effect on loaf volume and decreased sensory acceptability such as crust and crumb color, crumb grain, texture, and flavor. Wheat bran decreased lightness and imparted red and yellow tint. It was suggested that domestic wheat bran could be substituted for wheat flour at levels up to 15% without significantly depressing bread quality in the preparation of high-fiber bread. Crumb firmness of bread containing 15% wheat bran was significantly higher than that of the control bread (100% wheat flour) and increased rapidly at $2{\sim}3$ days during storage.

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.

Bread-baking properies of naked barley flour and naked barley-wheat flour blends were investigated, and changes of loaf volume of naked barley bread prepared by straight method and by lactic acid method were observed. Specific loaf volume of naked barley flour bread made by straight method was only 1.11 ml/g bread, while that of barley bread made by lactic acid method was more than 1.50 ml/g bread. No significant increase of loaf volume was noted in mixed naked barley-wheat bread. The increase of loaf volume of barley bread appeared to be due to total titratable acidity of barley dough. Loaf volume of what bread made by lactic acid method decreased sharply as the total titratable acidity of wheat flour dough increased.
