  • The purpose of this study was to investigate the properties of baguettes containing buckwheat flour. Physical properties of the bread flour mixed with buckwheat flour were tested by rapid visco analyzer(RVA), farinogram, and alveogram. Water activity of baguettes were measured and their properties were tested by rheometer. As the amount of buckwheat flour increased the peak viscosity and the holding strength were decreased, but the set back value was increased. Therefore, buckwheat flour prevented the gelatinization process. As the amount of buckwheat flour increased, the consistency and water absorption were increased, but development and stability were lower than the control. The bread flour containing high amount of buckwheat flour resulted in less breakdown and low farinogram quality number. As the amount of buckwheat flour was increased, Pmax, L, G, and W values were decreased on alveogram. The water activity and the springness of all samples were decreased during the storage, but the hardness was increased, especially after two days of storage. The sensory properties of baguette containing 10% buckwheat flour had the best scores.

  • This study was conducted to investigate the effects of mugwort powder on two types of flour batters, i.e., medium and cake, using the Falling Number test, RVA test, alveogram, and farimogram. The mugwort powder was added at 3% and 5% on the medium and cake flour bases, respectively. The Falling Numbers of the medium and cake flour batters with mugwort powder were increased due to the alteration of the protein in the flour. Analysis of the RVA characteristics showed that the addition of mugwort powder did not have significant effects on the initial pasting temperature. Peak viscosity, holding strength, final viscosity, and set back values of the medium flour batter were not consistent, but those of the cake flour batter were decreased. The characteristics of the alveogram showed that the addition of mugwort powder increased the extensibility and the swelling index. Farinogram demonstrated that the addition of mugwort powder decreased the water absorption and improved the stability of the medium and cake flour batters.

  • The purpose of this study was to investigate the properties of yellow layer cake with added buckwheat flour. The physical properties of the cake flour with added buckwheat flour were tested by RVA, farinogram, and alveogram, and then, after making the yellow layer cake, the samples were analyzed by rheometer. We found that the pasting temperature decreased with the addition of buckwheat flour in the cake flour, but peak viscosity, holding strength, and final viscosity increased. For the farinogram, the flour containing buckwheat showed increases for consistency and water absorption, but stability was decreased. The $P_{max}$ of the alveogram was not consistent according to the addition of buckwheat flour to the cake flour. The L- and G-values showed decreases, but they were not significant. After making the yellow layer cakes with added buckwheat flour, crumb softness was analyzed with storage for 7 days. The hardness and Max. G of the yellow layer cakes with buckwheat flour increased, and the highest values were after 1 day of storage. However, springness decreased with the addition of buckwheat flour as compared to the control, and showed the highest value at 7 days.

  • The objective of this study was to investigate the effects and availability of arrowroot powder in making white bread. The characteristics of pasting, farinogram and alveogram of the dough containing arrowroot powder were analyzed. Further, the physicochemical properties of white bread were analyzed by different mixing ratios (0, 3, 5 and 7%) of arrowroot powder during storage periods. When 7% of arrowroot powder was added, the initial pasting temperature of the dough by using a RVA (rapid visco analyzer) was significantly increased. Peak viscosity, holding strength, break down, final viscosity and set back were decreased by increasing added arrowroot powder. With the increasing amounts of arrowroot powder, the values of farinogram and alveogram parameter for the dough showed a tendency to decrement. The texture profile analysis of the white bread revealed that hardness, springiness, cohesiveness and gumminess were increased by adding arrowroot powder and further, the storage time was longer. By increasing the amount of added arrowroot powder, the L value of the white bread was decreased, whereas the a, b value were increased. In the sensory evaluation, the white bread of the control and that of the added 3% arrowroot powder showed the highest preference in total score.

  • The characteristics of sponge cake were investigated with various flour types and amounts of ginseng powder. Sponge cake made with medium flour in combination with 2 and 4% mixtures of ginseng powder was found to be optimal as a cake flour control, being unaffected by the addition of ginseng powder. The results of alveogram showed that increment of ginseng powder decreased over pressure(P), extensibility(L) and swelling index(G) value. Farinogram, consistency, water absorption, stability, time to breakdown and the farinograph quality number all decreased with increasing ginseng powder however, the longest development time was the medium flour with a 2% ginseng powder mixture. Water activities were not significantly affected by addition of ginseng powder, however the 2% ginseng powder mixture showed a slight decrease in water activity. Addition of ginseng powder caused an increase in darkness, as well as redness and yellowness. The results of the sensory test suggest that the 2% ginseng powder mixture was preferable for the cake flour control.

  • This study was carried out to evaluate the rheology of flour doughs containing 0.5% of hydroxypropylmethyl-cellulose (HPMC), methylcellulose (MC), and sodium alginate (SA), respectively. Farinograms, alveograms, a rapid visco analyzer (RVA), and rheofermentometer were employed in the analysis. According to the farinogram tests, the hydrocolloid additions caused changes in water absorption, dough development time, stability, and breakdown. The dough containing HPMC had the highest water absorption at $67.4{\pm}0.12%$. The HPMC dough also had the longest development time ($8.2{\pm}1.04$ min), stability ($12.7{\pm}0.42$ min), and breakdown ($7.9{\pm}1.3$ min). From the alveogram tests, P, G, and PIL values increased, whereas the L value decreased. The W values of the HPMC and SA doughs were increased, but that of the MC dough was decreased. According to the RVA results, the HPMC and SA doughs had reduced initial pasting temperatures whereas that of the MC dough was increased, but the difference was not significant. The peak viscosity of the MC dough also increased. Furthermore, all the doughs had increased breakdown times and decreases in final viscosity and setback. In the rheofermentometer tests, the HPMC dough presented the highest $H_m$, and the SA dough had the largest total volume.
