  • Flour characteristics and end-use quality of 10 commercial flours produced from Korean wheat (Kcom) were evaluated to assess consumersatisfaction with Korean wheat compared with commercial flour (Com) prepared from imported wheats. Two types of Kcom, whole wheatflour and white wheat flour, were found in various markets. Whole wheat flours showed higher ash and protein content, lower lightness, and higher water absorption in mixography, than did white wheat flours. The amylose content of Kcom was similar to that of Com, but peak viscosity and breakdown of Kcom were lower than those of Com. Noodle dough sheet prepared from white flours of Kcom was thinner and lighter than dough sheets prepared using whole wheat flours. Compared to Com, Kcom showed lower noodle dough sheet lightness. The hardness of cooked noodles prepared with Kcom was similar to that of noodles made from Com. When used for bread baking, Kcom showed lower loaf volume, lower crumb lightness, and higher crumb firmness, than did Com.

  • To determine the optimum condition for buckwheat noodle making, we prepared noodle from com posite flours of buckwheat, wheat and corn starch, and those physical properties and sensory evalua tion were investigated. The weights of cooked noodle became lower with increasing buckwheat content level indicating that elution of its components to soup was high. Wheat flour in the composite flours probably caused to drop gelatinization temperature and maximum viscosity compared to buck wheat flours. Corn starch in the composite flours increase gelatinization temperature and maximum viscosity compared to buckwheat flours. From the result of farinogram, buckwheat flour lower water absorption ability, and increased dough development time compared to composite flours. Adhesiveness of the cooked noodle with wheat flour was decreased. Cohesiveness of the cooked noodle was decrea sed with increasing buckwheat flour level. In sensory evaluation, chewing and softness of noodle with 100% buckwheat flour was evaluated the best. In taste, BW1 and BSW1 noodles showed slightly higher preference although there was no significant differences.

  • Practical use of wheat flour ferment with L. acidophilus during noodlemanufacturing was investigated. Water absorption decreased and overall mechanical tolerance index increased with ferment addition up to 20%. Amylograph of flour with ferment showed initial gelatinization temperatures of control, and 5% ferment-and ferment-added groups were equal. Maximum viscosity decreased by ferment addition. L, b and a values of dough increased proportionally with added ferment. Color of doughs with ferment was generally ligher. Total color difference of doughs added with ferment was higher than that of control group.

  • 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.

  • In this study, composite flour and dough were prepared with concentrated sweet pumpkin powder(CSPP) at varying concentrations of 3, 6, 9, 12, and 15%. The samples and a control were then compared with regards to quality characteristics, including moisture, protein, and ash contents, farinogram characteristics, amylogram characteristics, and falling number of flour and extensogram characteristics of dough, in an effort to determine the optimal ratio of CSPP in the formulation. As the CSPP content increased, the moisture and protein contents of the flour increased, whereas the ash contents decreased. With regard to the farinogram characteristics of flour, water absorption, development time, and stability decreased with increasing CSPP content, while weakness increased. The control group evidenced a significantly higher beginning temperature of gelatinization as compared to the CSPP samples. The temperature of maximum viscosity, maximum viscosity, and falling number of flour decreased with increasing CSPP content. With regard to the extensogram characteristics of dough, extensibility decreased with increasing testing time and CSPP content, whereas resistance, maximum resistance, and R/E ratio increased. In conclusion, these results show that $6{\sim}9%$ CSPP may prove very useful as a substitute for wheat flour in the production of hardroll bread, and may provide good nutritional and functional properties.

  • 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.

  • Rheolegical and baking properties of blends containing 10, 20 and 30 % of rice flours (Milyang 23, non-waxy and Tongil waxy) with wheat flour were investigated. Milyang-wheat blends showed higher amylograph paste viscosities at all reference points than waxy-wheat blends. Rice-wheat four blends had shorter farinograph stability than f·heat flour; however, the dough development time was similar between two blends. Breads produced from either Milyang-wheat or waxy-wheat flour blends at 10% rice level were acceptable compared with breads produced from wheat flour.

  • Scanning electron microscopy was used to study changes in granule shape, dough and cooked noodle structure of pea starch-wheat composite flour with 20% and 30% pea starch substitution. The granule shape of pea starch with low swelling power and solubility was oval, irregular and smooth, which had more a deep groove than corn starch and wheat flour. During gelatinization, pea starch after swelling was partially collapsed but it still held its main shape. The dough microstructure of 20% pea starch substitution showed compact structure distributed with more small starch granules than wheat dough and was held in discontinuous network. When cooked, more open filamentous network where starch gelatinization was complete were noticed. Swollen but partially collapsed large starch granules maintaining their shape were appeared in noodle structure after 30 min soaking in soup. In farinograph studies, 20% pea starch substitution to wheat flour showed that MTI value was as same as wheat flour even though stability was slightly decreased so that it was considered that it has proper property of noodle making.

  • The effects of defatted soy flour on the physicochemical characteristics of dough and bread making properties were studied. Defatted soy flour is added to wheat flour for bread-making in order to maximize the use of isoflavones in the soybean. Different particle sizes of both defatted soy flour and wheat flour were prepared by grinding and sievingwith meshes. In the mixograph test, the addition of defatted soy flour to wheat flour increased the requirement for water and decreased the dough development time. Water absorption rates were also investigated to determine the optimum quantity of water for good dough. As the level of defatted soy flour mixed with wheat flour increased, the sedimentation and P.K. values decreased. In comparison with control, the bread made with defatted soy flour especially had a lower specific loaf volume. Specific loaf volume of wheat flour-defatted soy flour bread prepared (Ed- this is an incomplete sentence, it's only a subject clause, and I don't how what you intend to state). In terms of the staling rate and hardness of the wheat flour-defatted soy flour bread, the increased defatted soy flour had a faster staling rate during storage at 5? than at 25? for 5days. From the result of sensory evaluation, wheat flour-defatted soy flour breads containing up to $4\%$ defatted soy flour were rated as being of high quality.

  • The effects of replacement of wheat flour with 10, 20, and 30% chestnut flour on the bread-making properties and quality characteristics of bread were evaluated. Among the physical characteristics of the dough, the development time in the farinogram decreased with increasing amounts of chestnut flour, and the dough stability and durability were reduced. In the amylogram, there was a slight increase in the gelatinization starting temperature when compared to the control flour, but the maximum viscosity gradually decreased in response to increasing amounts of chestnut flour. The expansion ratio did not increase in the dough containing 20 or 30% chestnut flour. Moreover, the loaf volume and specific volume of bread containing 20 and 30% chestnut flour were smaller than those of the control and the 10% treatment. The hardness of bread containing 10% chestnut flour($700g/cm^2$) was lower than that of the other treatments($1413-1,627g/cm^2$). Furthermore, bread containing 10% chestnut flour had denser porous structures than the other treatments. The sensory evaluation tests revealed that the 10% treatment had higher sensory scores for the internal and external qualities of bread than the other treatments.
