The quality characteristics of baguette bread added with water extracts of Liriopis tuber(LT) and effect of the diets containing 20% dried and powered baguette with 10% LT on the level of blood sugar and lipids in the diabetes induced rat by streptozotocin were investigated. pH of the dough added with 5∼10% LT was 5.00∼5.03 which were lower than that of control(5.12). The volume of the dough with 10% LT after 2nd fermentation was the biggest. Loaf volume index of the bread with 10% LT was significantly higher than that of control. $L^{*}$ values of outside and inside of the baguette decreased in proportion to the increase of the LT, while the $a^{*}$ values increased. Color of the bread with LT showed light dark-red. There was no significant difference in hardness, but springiness and gumminess were higher in the bread with 10% LT. Sweet taste increased, color acceptability and overall taste were enhanced by addition of LT, but it did not affect the sour and astringent taste. The overeating phenomenon showed in the diabetes rat decreased in the group fed with baguette bread with LT, while feed efficiency increased by feeding of the bread with LT. The level of glucose, neutral lipid and total cholesterol in blood were 118.92,95.47 and 37.42mg/dL in the control group, 245.60, 121.54 and 102.43 mg/dL in the diabetes control, 148.40, 103.25 and 57.63 mg/dL in the baguette diet group, respectively. There was no significant difference of HTR between control group and baguette diet group, while atherogenic index was considerably decreased, which might represent improving and preventing effects of diabetes.s.s.

The baking properties of rice bread with different percentages of butter and oil in wet and dry rice flour were investigated. The moisture, damaged starch, mean diameter, pasting properties by amylogram and RVA (Rapid Visco Analyzer), as well as thermal properties by DSC (Differential Scanning Calorimetry) of wet and dry rice flour were analyzed. The specific gravity and color (L, a, b) of the dough, as well as the appearance, color (L, a, b) and texture of the rice bread with different percentages of butter and oil in wet and dry rice flour were also analyzed. As a result, the wet rice flour were composed of a noted higher content in moisture, compared to the dry rice flour (p<0.001). The wet rice flour had lower values of damaged starch, higher values of mean diameter and a higher peak viscosity than was noted in the dry rice flour (p<0.001). The wet rice flour showed a higher degree of hydration and gelatinization than was seen in the dry rice flour (p<0.001). The prevailing principle to utilize the replacement of wet rice flour with oil had a significant effect on the volume, specific volume and hardness of the rice bread (p<0.001). The hardness of the rice bread also showed a decreasing trend as the amount of the added oil was increased into the mixture. These results suggest that the replacement of wet rice flour with 5.8% oil is effective for the production of rice bread.

Barley leaves tea white bread were prepared by the addition of 0.005, 0.010, 0.015, and 0.020% hemicellulase to flour of the basic formulation. The experiments and control were then compared in terms of quality characteristics, including pH, total titratable acidity, fermentation power of dough expansion, specific volume, baking loss, moisture content, color, textural characteristics, internal surface appearances, and sensory qualities in order to determine the optimal ratio of hemicellulase in the formulation. There were no significant differences in pH and total titratable acidity of dough and bread among the experiments. Fermentation power of dough expansion were increased as incubation time increased. Bread made by the addition of hemicellulase had significantly higher specific volume than the control group. However, lightness and yellowness showed the reverse effect. Greenness was not significantly different among the samples. Baking loss was the highest at the 0.020% addition level, and moisture content was maximal with the 0.010% addition, while the lowest in the control bread samples. As hemicellulase contents increased, harness and fracturability decreased. Resilience was maximal with the 0.015% addition, and was minimal in the 0.005% group. In the sensory evaluation, color, flavor, softness, overall acceptability, barley leaves flavor, delicious taste, astringency, bitterness, and off-flavor were not significantly different among the samples. In coclusion, the results indicate that adding 0.010% hemicellulase in barley leaves tea white bread is optimal for quality and provides a product with reasonably high overall acceptability.

This study was carried out to investigate the quality characteristics of breads with added Phellinus linteus grown in brown rice (BRPL). For color values, with increasing added BRPL powder, "lightness" decreased in the crumb while "redness" and "yellowness" increased ($^{***}$ p<0.001). The highest scores in volume and specific volume were observed in white pan bread with 5% BRPL powder added. When 10%, 15%, and 20% BRPL powder were substituted for equal amounts of strong flour, the volume and specific volume ratios of white pan bread decreased ($^{***}$ p<0.001). In texture measurements for white pan breads, hardness decreased slightly with the addition of 5% BRPL powder, but significantly ($^{***}$ p<0.001) increased with addition of 10%, 15%, and 20% BRPL powder. The addition of the BRPL powder significantly increased the springiness, gumminess, and brittleness of the white pan bread. The highest sensory scores for color, flavor, taste, and overall acceptance were obtained from white pan bread with 5% BRPL powder added ($^{***}$ p<0.001). By the results of these experiments, we can conclude that the hightest quality of bread with added BRPL powder has no more than 10% added BRPL powder content.

In this study, white bread was prepared containing 1.5, 3.0, 4.5 or 6.0% barley leaves tea powder (BLTP). The samples along with a control were then compared regarding their quality characteristics, including pH, total titratable acidity, fermentation power of dough expansion, specific volume, baking loss, moisture content, color, textural characteristics, internal surface appearances and sensory qualities, all to determine the optimal ratio of BLTP. As the BLTP content increased, the pH of the dough and bread and the lightness decreased, whereas the total titratable acidity increased. The fermentation power of dough expansion increased with a longer incubation time. The control group was evidenced by a significantly higher specific volume and baking loss than that observed in the BLTP samples. However, greenness and yellowness evidenced the opposite effect. Hardness was highest at a substitution level of 1.5% and lowest at a level of 4.5%. Fracturability and resilience were not significantly different among the samples. For the internal surface appearance, darkness and greenness increased both increased at higher BLTP content. In the sensory evaluation, color, flavor and overall acceptability were highest in the control bread samples but minimal at a substitution level of 6.0%. Softness was the highest at the 3.0% substitution level and lowest in the control bread samples. Barley leaf flavor, astringency, bitterness and off-flavor increased as the BLTP content increased. Delicious taste was not significantly different among the samples. In conclusion, the results demonstrated that 4.5% BLTP may prove quite useful as a substitute for wheat flour in the production of white bread and may provide favorable nutritional and functional properties.

Purpose: Pomegranate has been reported to exhibit medical properties such as antimicrobial, antimutagenic, anticancer, and anti-inflammatory effects. Especially the pomegranate peel as a by-product of the juice industry possesses more polyphenols with an antioxidant effect than the pomegranate flesh does. This study aimed to investigate the effect of the pomegranate peel on the quality characteristics of steamed bread. Methods: Steamed bread containing pomegranate peel was prepared with 0%, 1%, 3%, 5%, and 7% replacements of wheat flour with pomegranate peel powder, respectively. Results: The pH of dough significantly decreased from 5.66 to 4.42 with the amounts of pomegranate peel powder rising. After a 1st fermentation, the pH of all groups decreased. With an increase of the pomegranate peel powder level, the fermentation tension decreased from 42.83 mL to 29.03 mL. In addition, the volume, the specific volume, and moisture decreased as the pomegranate peel powder content level heightened. For color, steamed bread added with 7% pomegranate peel powder displayed low lightness but high redness and yellowness. In texture analysis, hardness and chewiness of the steamed bread rose as the pomegranate peel powder content increased, while the springiness and cohesiveness declined. Both total polyphenol and DPPH radical scavenging activity significantly increased with growing levels of pomegranate peel powder. In a sensory evaluation, the group with 1% pomegranate peel powder added showed the highest sensory preference scores for color, flavor, chewiness, taste, and overall acceptability. Conclusion: The results of this study suggest that steamed bread prepared with the addition of 1% pomegranate peel powder is the most optimal product for appropriate quality characteristics.

To develop and industrialize functional foods containing peanut sprout extract (PSE) and powder (PSP), the present study investigated the quality characteristics and antioxidant effects of breads prepared with 0, 0.5, 1, 2, 2.5, 5, 7.5, and 10% PSE and PSP. The expansion ratio of the dough, the quality characteristics such as volume, weight, specific volume, baking loss, color, texture, and sensory preference were evaluated. There were significant differences in the bread volume and specific volume among the control, PSE and PSP groups (p<0.001). Additionally, the weight and baking loss were decreased with an increasing amount of PSP (p<0.001). As the amount of PSE and PSP were increased, the L value of the crumb decreased, whereas the a and b values of the crumb significantly increased (p<0.001), suggesting that the crumb color of the bread may be significancy (p<0.001). As the amount of PSE and PSP increased, the hardness of bread significantly and rapidly increased from 5%. Meanwhile, there was no significance in springiness among the control, PSE and PSP groups. The total resveratrol content and DPPH free radical-scavenging activity of the bread significantly increased depending on the amounts of PSE and PSP (p<0.001). In the overall acceptance test, no significant differences were observed in the color, flavour, or texture, however, the taste and overall acceptance were significantly decreased between the control and the PSE group. All the sensory characteristics in the PSP group were significantly reduced compared with the control. Considering the above results, it can be expected that the suitable amount of PSE and PSP substituted for wheat flour will be from 1.0 to 2.5%. Furthermore, follow-up studies are being carried out continuously.

본 연구는 우리밀의 활용도를 높이기 위해 우리밀을 사용하여 방법을 달리해서 제조한 우리밀의 제빵 특성을 분석하였다. 우리밀 밀가루와 수입밀 밀가루 반죽의 Farinograph 분석 결과 견도(consistency)는 수입밀(534 FE)이 우리밀(503 FE)보다 높은 값을 나타내었다. 흡수율(water absorption)은 수입밀(66.1%)이 우리밀(60.6%)보다 높은 값을 나타내었다. 반죽형성시간(dough development time, DDT)은 우리밀(10.7분)이 수입밀(11.7분)보다 낮은 값을 나타냈다. 반죽의 안정도(dough stability time, DST)는 반죽의 강도를 나타내는데 수입밀은 Farinograph 반응시간을 20분으로 하여 평가하였을 때 20분까지도 반죽의 안정을 지키는 강한 반죽의 안정성을 나타내었으며, 우리밀은 15.2로 수입밀보다 낮은 DST를 나타내었다. Farinograph quality number(FQN)는 수입밀은 측정이 불가능할 정도로 높은 값을 나타내었고, 우리밀은 156으로 측정이 가능하였다. 이들 결과를 종합해 보면 우리밀은 수입밀에 비해 gluten network 형성 능력이 떨어진다는 것을 예측할 수 있었다. 제법을 달리한 식빵의 무게, 비용적 및 굽기 손실률 측정 결과 반죽의 방법이 식빵의 부피나 비용적에 중요한 영향을 미치는 것을 알 수 있었으며, 직접반죽법(straight dough method, SDM)이 부피나 비용적을 높이는 데 효과가 있었음을 알 수 있었다. 제법을 달리한 식빵의 crumb 색도 측정 결과 우리밀을 이용하여 제조한 식빵에서 높은 값을 나타내어 제법과는 상관없이 우리밀로 제조한 식빵이 좀 더 밝은 것을 알 수 있었다. 제법을 달리한 식빵의 소비자 기호도 조사한 결과 우리밀은 SDM 방법으로 반죽하여 제빵을 하는 것보다는 중종법(dough and sponge method, DSM)이 더 기호도가 높은 것을 알 수 있었다. 저장기간에 따른 제법을 달리한 식빵의 물성 변화를 측정한 결과 chewiness와 brittleness, hardness는 우리밀로 직접 반죽하여 제조한 빵(SDMK)이 저장기간 동안 가장 변화폭이 크게 변화하는 것을 알 수 있었으며, 100% DSM과 70% DSM 방법으로 제조된 식빵은 대조구인 수입밀로 직접반죽법을 이용하여 제조한 빵(SDMI)과 유의차가 없이 변화하는 것을 알 수 있었다. 또한 100% DSM 방법에 의해 제조된 식빵은 대조구인 SDMI 방법에 의해 제조된 식빵과 비교하였을 때 cohesiveness 등 물리적 특성이 유사함을 알 수 있었다. 결론적으로 gluten 함량이 부족한 우리밀을 이용하여 빵을 제조할 때 적당한 제빵 방법으로 100% DSM 방법을 활용하는 것이 바람직할 것으로 판단된다.
