  • The content of total dietary fiber in biji dried by hot air was 65.40%, and the percent of insoluble fiber and soluble fiber in total dietary fiber was 63.60% and 1.80%, respectively. In testing the feasibility of biji as a fiber source in cake, cakes were prepared with flour substituted with biji powder at the level of 0%, 5%, 10%, 15% and 20%. The Hunter value showed that the crumb colors of the cakes with 10%, 15% and 20% biji powder were significantly different from the control. The specific volume of the cake with 20% biji powder was significantly lower tan the other cakes. Cakes with 5%, 10% and 15% biji powder were les hard than the control after 10 days storage at 2$0^{\circ}C$. Sensory evaluations showed that their characteristics - crumb color, crumb texture, moistness, softness and overall preference - were significantly influenced by the replacement of flour with 10%, 15% and 20% biji powder. However, there was no difference in softness and overall preference of the cake prepared with 5% replacement compared to the control.

  • The principal object of this study was to assess the effects of garlic powder(2 % and 4 %) on the sponge cake made with medium and cake flour. After making sponge cakes with garlic powder, water activity, softness, color of crumb, and sensory test were tested. Water activity(Aw) of the sponge cakes with different quantity of garlic powder were increased during 7 days storage. These meant that garlic powder had absorption effect. The Max G and springiness of the sponge cakes with garlic powder were all lower than that of the control. With regard to the color of the sponge cakes, the L values were reduced, but the a and b values were increased with the increment of percent of garlic powder. The micrographs of the sponge cakes with garlic powder evidenced slightly lower porosity than the control. And, the results of sensory test showed that the increment of the addition of garlic powder had low scores. But we know the possibility to make the sponge cakes using garlic powder. And the sponge cakes with medium flour using 2% of garlic powder had better evaluation than others using garlic powder.

  • The overall effects of three different beers on white bread were examined in terms of mixograph, pH, fermentation rate, TPA, crumbScan, colorimeter, sensory evaluation, and the hardness of bread through different storage times (0, 1, 2, 3 days), and texture as measured by texture analyzer. According to mixograph, the control (CON), black beer stout (BOB) and Asahi beer (AOB) but not max beer (MOB) were found to be proper between 3 and 5 minutes of peak time. All samples for peak value were at the level of over 60%. AOB showed the highest specific volume, and was the lowest in hardness (i.e. highest in softness) by TPA and storage days. In sensory evaluation, the difference test showed that AOB had the best volume, springiness, moistness, and softness. Moreover, in an overall preference test AOB scored the highest points in texture, flavor, taste, and overall acceptance.

  • This study was conducted to investigate the effects of emulsifiers on the quality of steamed bread. initial pasting temperature of the flour was decreased from $63.8^{\circ}C$ to $59.40{\sim}62.95^{\circ}C$ by adding 1% of emulsifiers such as monoglyceride, lecithin, sugar ester and diacetyl tartaric acid esters of mono- and diglycerides (DATEM). But other rheological properties of the doughs were varied with different emulsifiers. Flour with 1% sugar ester showed the lowest value of final viscosity and set back, therefore sugar ester might be effective for retard the retrogradation of bread. By alveogram test, flour with 1% DATEM showed the highest value of P (tenacity) but the lowest value of L (extensibility), that means DATEM might be effective for strengthening tenacity of dough but it lowered extensibility. After 72 hours of storage test, the steamed bread based on the flour with 1% monoglyceride showed the best crumb softness and the highest score of sensory test.

  • In the making of yellow layer cake, shortening was replaced with olive oil at levels of 25, 50, 75, and 100%. The hunter values of L and b showed that the crumb colors of the cakes with 50 and 75% olive oil were significantly different from that of the control. Both 50 and 75% olive cakes showed a higher specific gravity of batters, and lower specific volume of cakes, than the control. Cakes with 50 and 75% olive oil were less hard than the control during 3 days' storage at $22^{\circ}C$. Sensory evaluation showed that their characteristics-cell uniformity, crumb color, taste, softness, and moistness-were not influenced by the replacement of shortening with olive oil. And same as above for overall acceptance.

  • Effects of oligosaccharides substituted for sucrose on the sponge cake quality were investigated. Fructooligosaccharide and isomaltooligosaccharide were used as oligosaccharides. Oligosaccharides decreased batter specific gravity, and increased cake specific volume and expansion ratio, showing that oligosaccharides had higher foaming ability and foam stability than sucrose. Oligosaccharides darkened the crust and crumb color of cakes. Addition of oligosaccharides made cakes darker, softer, more moist and more acceptable as perceived by panels. The acceptability was significantly correlated with crust and crumb color, softness, moistness and flavor(p<0.01). The textural characteristics including hardness, chewiness and gumminess of cakes were decreased by replacing sucrose with oligosaccharides. The hardness, gumminess and chewiness among sensory characteristics were negatively correlated with acceptability(p<0.05). Therefore, oligosaccharides should be a good alternative for sucrose in cake making because the sponge cake quality was greatly improved by partial repacement of sucrose with oligosaccharides.

  • In this study, domestic wheat white breads were prepared with the substitution of 1.5, 3.0, 4.5, and 6.0% Nelumbo nucifera G. tea powder(NNTP). The samples and a control were then compared with regard to quality characteristics, including pH, total titratable acidity, fermentation power of dough expansion, specific volume, baking loss, moisture content, color, textural characteristics, external and internal surface appearances, and sensory qualities in order to determine the optimal ratio of NNTP in the formulation. As the NNTP contents increased, the pH of dough and bread, baking loss, and lightness decreased, whereas the total titratable acidity of dough and bread increased. The fermentation power of dough expansion increased with increasing incubation time. The NNTP samples evidenced significantly higher specific volume, greenness, yellowness, resilience, and crumb consistency than were observed in the control group. However, hardness and fracturability evidenced the opposite effect. The water content and uniformity of the crumb pores were highest at a substitution level of 1.5%, and were lowest at a level of 4.5%. Crumb color, flavor, and delicious taste decreased with increasing NNTP contents, whereas lotus leaf flavor, astringency, bitterness, and off-flavor increased. Density of the crumb pore and crumb springiness were not significantly different among the samples. Softness, chewiness, and overall acceptability were maximal with the 1.5% substitution, and were minimal in the 6.0% group. In conclusion, our results demonstrate that $1.5{\sim}3.0%$ NNTP may prove quite useful as a substitute for domestic wheat flour in the production of white bread, and may evidence favorable nutritional and functional properties.

  • The effects of Angelica gigas nakai powder on bread quality during storage period were evaluated. Breads were prepared by the addition of 0, 0.5, 1, 2, 3, 5 and 10% of Angelica gigas nakai powder to flour of the basic formulation. The moisture, crude protein, crude fat and crude ash contents of the bread decreased by increasing amounts of the Angelica gigas nakai powder were the lowest in the control group. There were no significant difference in pH of the bread among each experiment groups. The weight of bread increased with increasing Angelica gigas nakai powder concentration, while the volume of dough decreased. In color values, with increase of Angelica gigas nakai powder concentration, L value decreased in the crust and crumb, but a and b values increased. As the results of texture, hardness, gumminess and chewiness were increased with increase of Angelica gigas nakai powder concentration, but adhesiveness, springiness and cohesiveness were decreased. Softness in the crumb stored for 1 or 7 days was the highest for the bread made with 2% Angelica gigas nakai powder, and chewiness was the lowest for the bread made with 5% Angelica gigas nakai powder. The water activity in the bread stored for 3 days was the highest for the breads made with 2% and 3% Angelica gigas nakai powders. After 7 days, the water activity tended gradually to decrease. In the results of sensory evaluation, the quality of the 0.5% or 1% Angelica gigas nakai powder bread showed the highest in taste and flavor. The color, taste, flavor, appearance, texture, and overall acceptability of the bread decreased with the increasing Angelica gigas nakai powder content. Considering the able outcome, the addition of Angelica gigas nakai powder by 0.5% and 1% is thought to play a role as a functional breads, along with the improvement of quality.

  • Purpose: To improve the quality of basic gluten-free rice bread composed of white rice flour, salt, sugar, yeast, skim milk powder, olive oil, and water, the effects of transglutaminase (TGase), whey protein (WP), propylene glycol alginate (PGA), and hydroxypropylmethylcelluose (HPMC) were investigated. Methods: TGase, WP, PGA, and HPMC were added to rice flour cumulatively. The pasting properties of rice flour blends as well as volume, shape, color value, textural properties and sensory evaluation of basic rice bread (RB1) RB1+TGase (RB2), RB1+TGase+WP (RB3), RB1+TGase+WP+PGA (RB4), and RB1+TGase+WP+PGA+HPMC (RB5) were compared. Results: Consistency of rice batter increased upon addition of TGase, WP and PGA, and RB3 and RB4 had higher specific volumes than others. PGA improved volume, crumb air cell uniformity, and resilience but lowered elasticity and moistness of RB. HPMC increased, hardness, moistness and softness, and slightly reduced volume. Conclusion: Therefore, it is suggested that hydrocolloids, PGA and HPMC may be necessary to improve volume, crumb structure, textural properties and overall eating quality of gluten-free rice bread.

  • This study was conducted to assess the effects of mugwort powder (3% and 5%) on sponge cake made with medium and cake flour. After preparing sponge cakes with mugwort powder, the water activity (Aw), softness and color of crumbs were tested and the sensory properties were evaluated. The water activity of the sponge cakes containing different quantities of mugwort powder did not differ greatly. The springiness and hardness of the sponge cakes with mugwort powder were all lower than that of the control. With regard to the color of the sponge cakes, the L values were reduced, but the a and b values were increased in response to the addition of mugwort powder, resulting in the sponge cake containing mugwort having a darker color. The micrographs of the sponge cakes with mugwort powder showed a slightly lower porosity than the control. In addition, the results of the sensory test showed that cakes containing mugwort powder had low scores. However, it is still possible to make the sponge cakes using mugwort powder and the sponge cakes prepared with flower containing 3% of mugwort powder had better evaluation than those prepared using other amounts of mugwort powder.
