  • Effects of substituting wheat flour with rice flour on bread-making properties were investigated. Rice(Oryza sativa L.) cultivars were 'Goami2(G2)', a functional rice containing higher non-digestible carbohydrates, and 'Chucheongbyeo (CC)', an ordinary Japonica rice. Rice flour was substituted at 10, 20 and 30% in wheat bread formulation, and the composite flour was used for yeast-leavened bread making. Peak and final viscosity of G2 rice flour was significantly lower than that of CC rice flour. Mixograph analysis indicated that replacement of G2 rice flour increased dough water absorption and mixing time compared to wheat flour. But, typical mixograph pattern was not found in the dough from composite flour with CC rice flour. As increasing the amount of rice flour, the G2 rice breads showed a significant decrease in loaf volume, but an increase in bread crumb firmness(g). For the CC rice breads, no significant difference(p<0.05) was observed in loaf volume and crumb firmness, ranging 1012~1050 cc and 433~482g, respectively. The results revealed that Chucheongbyeo is more suitable for bread-making with the composite flour of rice(10~30%) and wheat flour.

  • This study was conducted in order to investigate the properties of bread making and quality improvement when wheat flour is replaced with whole waxy sorghum flour. Sorghum flour, which was prepared with two types of milling methods of pin mill and ultra fine pulverization, was used at different levels ranging from 10, 20 and 30%, respectively. The pasting properties of peak viscosity, setback viscosity and pasting temperature of the composite flour containing pin-milled sorghum flour were higher than those of ultra fine pulverized sorghum flour. The volumes of sorghum bread were lower than that of wheat bread; moreover, they gradually decreased with increasing amounts of sorghum flour, which has inferior dough properties and therefore collapses in the oven. The use of vital gluten (12% based on sorghum flour weight) and emulsifier (SSL; sodium stearoyl lactylate) increased the extensibility and resistance to the extension of the dough, thereby improving its rheological properties. Thus, the oven spring of bread containing sorghum was improved, demonstrating as loaf volume increase up to 15%. However, in the case of breads containing 30% sorghum flour, the loaf volumes were still unacceptably low. Therefore, the formula and the bread making process were further modified as follows: An increase of vital gluten ($12%{\rightarrow}18%$) and shortening ($3%{\rightarrow}6%$), a decrease of mixing time and dough fermentation temperature, and the addition of sorghum flour after gluten development during mixing. The above modifications resulted in the improvement of sorghum bread quality. Therefore, we suggest that pin-milled sorghum flour is more appropriate than ultra fine pulverized sorghum flour for making bread.

  • 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.

  • In order to streamline bread making process that is time-consuming in regard to the characteristics of process, this study focused on microwave irradiation to dough and raising its temperature to monitor potential variations of dough properties and bread quality, and also examined optimum irradiation time to deduce effective ways for streamlining bread making process. According to analyze dough properties depending on microwave irradiation time, it was found that microwave heat (MWH) 2 showed the highest specific volume and oven spring of all and the lowest hardness (i.e. the highest softness). Moreover, MWH 2 scored the highest points in overall preference under sensory characteristics. As a result, it found that 80-second heating of 700 g bread dough, when exposed to microwave irradiation, contributed to the highest quality of bread.

  • This study investigated the bread-making properties of rice bread supplemented with HPMC (hydroxypropyl methylcellulose) 1~3% and gluzyme (glucose oxidase), fungamyl (fungal ${\alpha}$-amylase) and pentopan (xylanase+hemicellulases) (0.0015~0.0090%). The viscoelastic properties of the dough with HPMC 1~3% were analyzed. When the rice flour was supplemented with HPMC 1~3%, the viscoelastic properties of the dough tended to increase as the amount of added HPMC was increased. The physicochemical characteristics of the rice bread with HPMC, gluzyme, fungamyl, and pentopan were analyzed. Supplementing the rice flour with HPMC, gluzyme, fungamyl, and pentopan had a significant effect on the volume (p<0.01) and specific volume (p<0.001) of the rice bread. Supplementing the rice flour with 3% HPMC and 0.0045% or 0.0090% pentopan had a significant effect on increasing the volume (p<0.01) and specific volume (p<0.001) of the rice bread. Supplementing the rice flour with 3% HPMC, 0.0023% gluzyme and 0.0015% fungamyl had a significant effect on increasing the volume (p<0.01) and specific volume (p<0.001) of the rice bread. These results suggest that supplementing the rice flour with HPMC, gluzyme, fungamyl and pentopan is effective for the production of rice bread.

  • To examine the quality characteristics of bread made of different amounts of chia seed powder, a functional food ingredient, this study made bread by adding chia seed powder by 1%, 3%, and 5% of the flour weight. When bread dough properties were determined using mixograph, all doughs were appropriate for bread-making. In the evaluation of fermentation rate, the dough with 3% of chia seed powder CS 3 showed the most favorable fermentation rate during the first 60-min fermentation of the bread. According to CrumbScan, the fineness of bread pores were higher in control group than bread loaves containing chia seed powder. The volume of bread in control group was significantly lower than those of other experimental groups. The volume and specific volume were highest when chia seed powder was added by 3%. According to preference analysis, appearance and taste was best in CS 3, showing the highest overall score in preference. Therefore, the optimum amount of chia seed powder is identified to be 3% in bread-making.

  • Six Domestic Wheat Tapdong, Eunpa, Kobun, Olgru, Uri, Kumgang cultivars and one standard wheat Dark Northern Spring (DNS) were milled and determined bread-making properties of dough and bread made the wheats. The ash contents of DNS showed 0.54%, on the other hand, domestic wheat flours showed lower contents than DNS, and Kumgang was the lowest. The Protein contents which suggest the flour gluten content showed 11.68% in DNS cultivars, however 13.85% in Kumgang, 12.35% in Eunpa, 12.32% in Kobun. Valorimeter value in Farinograph data for Kumgang, Kobun, Eunpa cultivars which evaluate the dough formation time and stability showed better result than DNS. Resistance rate in Extensograph for Tapdong and Kobun showed higher rate than DNS. Gelatinization temperature in Amylograph for DNS, Tapdong, Eunpa, Kobun, Kumgang revealed 59$\^{C}$, 59$\^{C}$, 58$\^{C}$, 58$\^{C}$, 59$\^{C}$ respectively, but Uri, Olgru cultivars showed upper temperature which suggest the two cultivars was not suitable for bread making. W(gluten strength) in Alveograph data for DNS showed 297, however, 386 for Tapdong, 327 for Kumgang which indicated that the upper domestic wheat cultivars satisfactory the bread-making properties. In the CO$_2$production of straight bread doughs measured with Meissle fermenter for 5hr, Kumgang cultivar showed the highest CO$_2$ as 333 mg per 30 g of dough. The breads prepared with the above domestic wheat flours showed acceptable quality in sensory test for parameters such as volume, color of crust, symmetry of form, crust, evenness, grain, color, texture, aroma, taste, but the bread made DNS seemed to be superior in organoleptic property to the breads made with domestic wheat flours. The sponge dough bread made with Kumgang cultivars showed the best organoleptic quality among the wheat flours tested. These results indicate that the Kumgang seemed to be practical wheat variety for bread-making.

  • This study was conducted to compare the protein characteristics, dough rheology and bread loaf volume of Korean wheat cultivars and CIMMYT lines produced in diverse environments and to determine the genetic and environmental effects on bread making quality. Protein characteristics, including protein content and SDS-sedimentation volume, mixing properties during dough development and bread loaf volume were primarily influenced by the environment. Wheat cultivated in Jinju exhibited higher SDS-sedimentation volume based on constant protein weight and bread loaf volume than those in Suwon and Iksan. SDS-sedimentation volume based on constant protein weight, mixing time of mixograph and mixing tolerance of mixograph were positively correlated with bread volume. Korean wheat cultivars showed different allelic variations of $Glu-1$ and $Glu-3$ compared to CIMMYT wheat lines. Alchanmil, Keumkangmil and Tapdongmil could be suitable for bread making because these cultivars exhibited a 10 point $Glu-1$ score. However, Korean wheat cultivars should be introduced specific alleles in $Glu-3$ loci, including $Glu-A3b$ or $d$ and $Glu-B3b$, $d$, $f$ or $g$, to improve gluten strength related to increase bread loaf volume.
