  • This study was conducted to evaluate quality characteristics of white breads with Acanthopanax senticosus extract(ASE) (0, 25, 50, 75 and 100%). Addition of ASE significantly decreased L-value, and increased a and b-values. Compared with the control bread, specific volume of bread added with ASE was increased. The cohesiveness, springiness and gumminess of the breads added with ASE were higher than those of the control group. Also, a sensory evaluation was carried out in terms of acceptability(color, flavor, taste, texture and overall acceptability). Taken together, the 50% treatment ranked the highest evaluation values, as compared to other treaments. Accordingly, to improve the quality of bread, it is recommendable to add ASE to the 50% level in substitution for water in making a loaf of bread. After all, this study was to confirm the possibility of ASE's utilization as natural materials containing the functional substance.

  • To develop health food using old pumpkin, freeze-dried old pumpkin powders were added into wheat flour in the ratio of 0, 1, 2, 4, and 8% and the quality characteristics of the baked products were investigated. Moisture content and water activity of breads with added pumpkin powders were raised from 42.22 and 0.528 in 1% addition ratio to 0.576 and 44.39% in 9% addition ratio compared to 40.69% and 0.521 in the bread of non-added, respectively and these increases were due to the effect of the added pumpkin powders. Water holding capacity of the added pumpkin powders raised the weight of the breads while the specific volume was decreased at that time. In the Hunter's color values, as the pumpkin powders content increased, 'L' and 'a' values were decreased while 'b' value was increased from +29.44 in 1% addition ratio to +45.58 in 8% addition ratio of freeze-dried old pumpkin powders compared to +12.65 in the bread of non-added. In the texture properties, hardness, fracturability, springiness, cohesiveness, gumminess and chewiness were increased by the added content of pumpkin powders hardness to 561 g in the bread withof 8% added pumpkin powders from 248 g in the bread of non-added. Judging from texture, taste and overall acceptability of the product, the recommended substitution level for freeze-dried old pumpkin powders in bread was 4% or less

  • The purpose of this study was to investigate the antioxidative effects of Mori Cortex Radicis powder and to determine the optimal mixing ratio of Mori Cortex Radicis powder and water in the preparation of bread. The optimal sensory composite recipe was determined by producing bread with different levels of Mori Cortex Radicis powder and water. The analysis was performed using response surface methodology and a sensory evaluation was performed with the data. Ten experimental recipes, including two with reference points in the composition, were selected. In terms of the antioxidative effects of Mori Cortex Radicis powder, the $IC_{50}$ for total phenolic content and DPPH free radical scavenging activity were 149.56 GAE/g dry powder and 137.77 /mL respectively. Measurement results of the mechanical properties showed differences in volume (p<0.05), baking loss (p<0.05), yellowness (p<0.01), lightness (p<0.01), redness (p<0.01), hardness (p<0.01) and springiness (p<0.05). The sensory measurements showed significant values for color (p<0.05), appearance (p<0.05), flavor (p<0.01), taste (p<0.01), and overall quality (p<0.01). Overall, based on numerical and graphical methods, the optimal formulation was determined to be 21.16 g of Mori Cortex Radicis powder and 372.47 g of water.

  • The effects of replacement of wheat flour with laver, Pyropia yezoensis, on the bread making properties and quality characteristics of bread were evaluated. The poor baking performance which arose from dried laver addition could be compensated by using exogenous enzymes (Flavouzyme) and baking aids. Laver hydrolysate was prepared by hydrolyzing laver using Flavouzyme for 9 hrs at $50^{\circ}C$. Doughs made by addition of laver hydrolysate (8% dried laver substitution level) showed excellent baking properties. Moreover, with the addition of glucose oxidase and hydro colloidal HPMC, loaf volume and crumb grain were improved for doughs containing laver hydrolysate. Both of intermediate fermentation and final proof time for doughs containing laver hydrolysate was shorter than that for conventional dough.

  • The rheological properties of wheat flour dough and qualities of bread prepared with 0, 10, and 20% of dietary fiber slurry extracted and purified from ascidian (Halocynthia roretzi) tunic were investigated. Water absorption of the dough increased with the increase of dietary fiber slurry. Both arrival and development time of the dough with 10 and 20% dietary fiber slurry added were shorter than those of the control. An increase in the added amount of the dietary fiber slurry resulted in an increase of weakness. The dough's extensibility and resistance to extension were decreased, and the ratio of resistance to extensibility (R/E) decreased with the increase in the dietary fiber slurry. The maximum viscosity gradually decreased with the increase in the amount of dietary fiber slurry, while the temperature of gelatinization was not changed. Both loaf and specific volume of bread were slightly decreased with an increase in the amount of dietary fiber slurry. Overall preference scores by sensory evaluation and the quality characteristics of the bread with up to 20% dietary fiber slurry added was not significantly different from those of the control(p<0.05). The results indicated that the addition of the dietary fiber from ascidian tunic retarded staling and improved the shelf-life of the bread by enhancing the water holding capacity.

  • In order to make use of Job's tears widely, Job's tears starch was analyzed and determinded the contents of amylose, amylographical and other physicochemical properties. And also the yeast breads and rice cakes were made from flour and rice flours with various mixing ratios of Job's tears flour and then they were tested for suitability to preparation of bread and rice cake. 1. The starch contents of Job's tears showed 12~20%. Which was about one third of rice or waxyrice starch. But amounts of crude proteins, fats, and total ashes in Job's tears were higher than rice or waxyrice. Job' tears starch was composed of amylopectins only, and was similar to that of waxyrice starch. 2. Depends upon the Amylogram of each starch, initial gelatinization temperature of Job's tears starch was the highest among three starches of rice, waxyrice, and Job's tears. Maximum viscosity of Job's tears starch was 860BU, then it was about two times of rice starch viscosity. 3. By the sensory evaluation results, the taste of bread prepared with mixing of 10% Job's tears flour was better than flour bread and the volume and grains of the bread made from mixing of 10%, 20% Job's tears flour were similar to that of flour bread, but the taste, volume and grains of bread made from 30% mixed flour were undesirable. The rice cake Prepared from mixed flour with 25% Job's tears flour has shown to be desirable.

  • The purpose of this study was to investigated quality properties of breads prepared from wheat flour with persimon leaf power. Results showed that the volume of bread was lessened, the weight of bread went up, and baking loss rate diminished as persimmon leaf powder content incremented. The experiment showed that bread was maintained in the low level of springiness and cohesiveness was relatively reduced as time lapsed, whereas 3.0 and 5.0% test group remained significantly high level. There was a rapid increment in chewiness and gumminess, which tended to show significantly low as compared to control group, Results of sensory evaluation showed that the preference scores decreased as the persimmon leaf powder contents increased (p<0.05), flavor made no significant differences up to 3.0% test group, however, 5.0% test group containing elutionsuch as catechin or tannin produced sour and bitter taste so strongly that made if feel uncomfortable with. The augment of content indicated a low prederence in terms of texture, in an overall preference had no significant differences as compared to the control group, and 0.5% test group. Through the results of these of these experiments, we can conclude that the highest quality of persimmon leaf powder content is no more than 0.5% in making bread added with persimmon leaf powder.

  • The purpose of this study is to determine potential effectiveness of sourdough starter powder (made of Korean wheat flour) in the quality characteristics of bread and in the substitution effect of a dough improver in bread baking. The bread containing sourdough starter powder was considered to be most suitable for making sourdough bread. As a result, SP 10 showed the best fermentation rate and the highest volume and specific volume. In sensory testing, SP 10 was most preferable among others. According to experimental comparison between optimal addition ratio of SP 10 and other sourdough starter powder products available in Korean domestic market, SI had the highest fermentation rate, highest volume and specific volume. Analysis of texture showed that SI was soft with the lowest hardness and the highest elasticity. Sensory test showed that SI was most preferable of all, and SP 10 was more preferable than BP. It was concluded that SP 10 was not less preferable in the aspect of preference at sensory test than other products. Hence, it is expected that sourdough starter powder made of Korean wheat flour will be possibly more popular and effective in replacing some portion of dough improver of baking.
