  • This study investigated quality characteristics of sourdough bread using fermented fig. Bread containing sourdough, compared with control group, showed high inclination in moisture content. Sample with 20% of sourdough was the highest, and sample with 40% of sourdough was the lowest. There was a significant difference among samples. As for appearance and cross structure of sourdough bread with fermented fig, there was an inclination that the bigger sourdough bread is, the bigger cell is and the more even its structure is. As for the chromaticity, sample with 20% of sourdough showed the lowest value of L and value of b. Value of L and b got lower as its volume got bigger. Value of a, on the one hand, showed no fixed inclination. As for textural characteristics, sourdough bread showed lower hardness, cohesiveness, and gumminess, and higher springiness and cohesiveness than control group. There were significant differences among all items, but there was no significant difference in hardness, springiness, cohesiveness, and gumminess among samples. Changes in result of sensory analysis suggested that sample with 20% of sourdough showed the highest overall preference including color, flavor, taste, and appearance. On the other hand, sample with 40% of sourdough showed the lowest overall preference. Considering preference through sensory analysis and quality characteristics of sourdough bread with fermented fig, therefore, it seemed that sourdough bread with 20% of sourdough had the best characteristics.

  • Oat flour was purchased and investigated for quality characteristics of oat bread. Antioxidant and flour pasting properties of oat flour, and water content, weight, volume, Hunter color value, texture of bread were measured. DPPH radical scavenging capacity (%) of oat extract was 68.49%. Pasting temperature of oat flour ranged between $66.60^{\circ}C$ and $70.93^{\circ}C$. Flour pasting properties of sample added with 10 and 30% oat flour was shown similar results compared with wheat flour. Final viscosity of sample was increased by adding concentration of oat flour (up to 311.65 RVA). Water content (%) of bread was shown increasing trend by adding oat flour. Weight of bread loaf with 100% oat flour was shown higher score than other samples. Volume of loaf by adding oat flour of 10, 30, and 50 % ratio was 550, 450, and 388 mL, respectively. The Hunter color $L^*$ values of bread by adding oat flour was dark compared with wheat bread. Color value of bread added 10% oat flour was similar results with $L^*$ values of bread with wheat flour. The bread added with 20 and 30% oat flours had the higher hardness, gumminess, and chewiness compared with other samples. Cohesiveness of the bread with wheat flour showed higher than that of bread added with oat flour and increased by storage period. The growth of total viable cell was inhibited depending on the concentration of oat flour during storage.

  • 본 연구의 목적은 유산균 배양액과 계피 추출물을 물 대신 첨가하여 제조한 sourdough의 제빵 특성과 식품첨가물로서의 계피의 다양성을 연구하였다. 반죽의 무게는 시료간에 차이가 없었고, 식빵의 무게는 D 식빵에서 가장 높았다. 식빵의 부피와 비용적은 C 시료에서 가장 높았고, 굽기손실율은 대조구에서 가장 높았으며 각각의 식빵 시료 간에 통계적으로 유의미한 차이가 있었다. 수분함량과 pH는 계피추출물 첨가량이 증가할수록 낮아졌고, 각각의 식빵 시료간에 통계적으로 유의미한 차이가 있었다. 적정산도는 유산균 배양액 첨가량이 증가할수록 낮아지는 것으로 나타났으나 각각의 식빵 시료간에 통계적으로 유의미한 차이는 없었다. 색도에서 백색도는 계피첨가량이 증가할수록 낮아졌고, 적색도와 황색도는 유산균 배양액 첨가량이 감소할수록 높아지는 것으로 나타났으며 각각의 식빵 시료간에 통계적으로 유의미한 차이가 있었다. 식빵의 물성을 측정한 결과에서 유산균 배양액이 감소하고 계피추출물이 증가할수록 경도, 점착성 및 씹힘성은 증가하였고, 탄력성과 응집성은 감소하였다. ALH(Lactobacillus sakei subsp. ALI033) 유산균 배양액과 계피 추출물을 첨가한 sourdough로 제조한 식빵은 대조구보다 부피와 물성을 향상시키는 것으로 나타났고, 계피 추출물과 같은 부재료를 첨가하여도 식빵 제조가 가능한 것으로 나타나 ALH 유산균 배양액과 계피주정 추출물의 다양한 활용이 가능할 것으로 생각된다.

  • This study examined the quality of bread made from a wheat flour, oat powder, and wild carrot powder mixture. The lightness and redness values decreased with increasing amount of wild carrot powder addition, while the yellowness was increased significantly. In a sample of wild carrot powder addition, the total volume was lower than the control. The texture profile analysis of oat bread, such as hardness, gumminess and cohesiveness decreased significantly with increasing amount of wild carrot powder addition. In the case of springiness, the value was not significant. The sensory evaluation of oat bread was significantly different in all analyses. Oat bread (BCB2.0) containing 2.0% (w/w) wild carrot powder showed the highest value in the four sensory evaluation items. Therefore, the 2.0% (w/w) addition of wild carrot powder addition was appropriate. An analysis of the physicochemical active component and DPPH scavenging activity of oat bread revealed a higher total flavonoid and total polyphenol content than normal bread. The DPPH scavenging activity was also 20.3% compared to the wild carrot powder. The availability of wild carrot powder in oat bread could be identified.

  • The quality characteristics of breads made by adding levels of 30%, 60%, and 100% aloe gel were investigated. The 60% aloe gel sample had a larger dough volume than the control dough. Also, the loaf volume and specific volume of the bread made with 60% aloe gel were larger than those of the control bread. The pasting temperature increased gradually with the increasing amounts of substituted aloe gel as compared to wheat flour with water added$(66.5{\pm}12^{\circ}C)$; the wheat flour with 100% aloe gel had a pasting temperature of $90.7{\pm}1.1^{\circ}C$. Peak viscosity decreased gradually with increasing amounts of aloe gel when compared to the wheat flour with water added. Setback also was decreased gradually with the increasing amounts of aloe gel as compared to the wheat flour with added water. From the setback decrease it is suggested that the aloe controlled retrogradation of the bread during short-term storage. The crumb color of the bread made with the aloe gel was not significantly different to that of the control bread, and the color of the crumb was yellow-white. Bread hardness decreased gradually with increasing amounts of the substituted aloe gel. However, bread gumminess and chewiness increased gradually with increasing amounts of aloe gel. The springiness of the bread made with 100% aloe gel was lower than that of the control bread. With regard to flavor and taste, the bread made with 100% aloe gel produced a green-like odor and had a bitter taste. The mouth feel of the breads made with aloe gel was considered soft and moist. The overall acceptabilities of the breads made with 30% and 60% aloe gel were not significantly different from the control bread, but the bread made with 100% aloe gel had a green smell and bitter taste. Yet accordingly, the results indicate that functional and health products with improved quality could be developed by adding aloe gel to breads and cakes.

  • This study was carried out to investigate the quality of white pan breads as affected by various amounts of Terminalia chebula Retz (TC) powder, in which the breads were prepared with 0, 2, 4, and 6% TC powder. The samples and a control bread were compared in terms of bread quality characteristics, including pH, baking loss rate, loaf volume index, moisture content, TBARS values, texture, color, and sensory qualities in order to determine the optimal amount of TC powder in the formulation. The pH levels of the bread samples containing TC powder ranged from 5.30 to 5.44, while the control bread had a pH of 5.68. The loaf volume index values of the samples prepared with 2~6% TC powder were lower than that of the control. After 7 days storage, the moisture content of the control bread had decreased by 14.4%, while the moisture contents of the breads with added TC powder had decreased by approximately 8~10%. The breads with TC powder had lower TBARS values as compared to the control bread. For texture characteristics, hardness increased with the addition of TC powder, and was especially increased in the sample containing 6% TC powder. Cohesiveness and springiness, however, decreased with the addition of TC powder. For color, lightness of the bread crust and crumb decreased with the addition of TC powder, whereas redness and yellowness increased. In terms of sensory quality, the bread containing 2% TC powder was preferred over the control bread, as estimated by appearance, crust color, taste, and overall quality, while the 6% TC bread had the lowest preference scores. These results suggest that the addition of 2% TC powder to white pan bread had optimal effects for improving shelf-life and enhancing bread quality.
