The possibility of buckwheat-wheat flour mixture as bread was studied by adding 10, 20, and 30% of buckwheat to wheat flour. To improve bread-making quality of the mixture, gluten, ascorbic acid, and hydroxy propyl methyl cellulose (HPMC) were added to 30% buckwheat-wheat flour and sensory evaluation was also exercised on it. The weight of bread increased but the volume of that decreased as the percentage of buckwheat to wheat flour increased, and improved bread-making quality by adding gluten, ascorbic acid, HPMC to 30% buckwheat-wheat composite flour. When it comes to color, color of the bread got darker as the percentage of buckwheat increased, got brighter when gluten and HPMC were added and showed little difference when ascorbic acid was added. Texture of bread increased in maximum weight, strength, hardness but decreased in springiness and cohesiveness. The use of additives showed influence to the some results. In terms of the aging process, enthalpy increased with storage time, and it could be slowed down by the use of the additives. The sensory evaluation shwoed that 10% buckwheat-wheat bread was most excellent, 20% bread was similar to other bread made from wheat flour, and the bread made by mixing additives were better than just 30% buckwheat-wheat flour in terms of quality.

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.

The quality of the buckwheat bread made with previously heated ($55^{\circ}C$) and cooled buckwheat flour 0dough with the addition of ascorbic acid(AA) or/and sodium stearoyl lactylate(SSL) was evaluated . With heat treatemtn , handling property of dough and grain of the bread crumb were markedly improved and stickiness of the dough decreased . The optimum resting time to produce the best loaf volume and grain was found to be 3hr for both unheated and heated doughs. Heat treated dough showed higher dough expansion rate during fermentation than unheated dough, even though heated dough had lower loaf volume, probably because of an improper oven spring. Increase in shortening of dough formula from 3% to 5% improved loaf volume without improvement of handling property. With the addition of 100 ppm AA or/and 0.5% SSL, loaf volume and crumb grain were improved for both unheated and heated doughs.Microscopic analysis of a mixed dough by scanning electron microscope (SEM) showed that heated dough had a continuous network whereas unheated dough was discontinuous. The addition of AA and SSL gave the dough a more continuous network whereas unheated dough was discontinuous . The addition of AA and SSL gave the dough a more continuous structure with strengthened strands or interactions between the starch granule and protein. Therefore, it appears that the presence of continuity in heated buckwheat breadwheat bread dough is related to the improved loaf volume and crumb grain without dough stickness.

This study was conducted to compare the quality of steamed cakes supplemented with common buckwheat(F. esculentum Miench.) and tartary buckwheat(F. tartaricum Gaetn). A proximate analysis, and rutin content, color value, texture characteristics and sensory evaluations were performed, In the proximate analysis, the steamed buckwheat as opposed to raw buckwheat, appeared to afford higher values for most of the evaluated items. The rutin content of the tartary buckwheat was over 14 times higher than that of common buckwheat and remained about 58% higher after steaming. The lightness of the steamed cakes was in the following order: control(wheat flour only), with the addition of common buckwheat, and with the addition of tartary buckwheat. The redness and yellowness increased in the following order: tartary buckwheat, common buckwheat, control steamed cake. There were no significant differences in the springiness of steamed cake between the various samples including the control: therefore, resulted in good quality during bread-making. In the sensory evaluation, on increasing the amount of tartary buckwheat addition the score for entire taste increased compared with common buckwheat and the control and also had positive results for all other items, including flavor, color, softness and moistness. This study has suggested the ability to make steamed cakes containing tartary buckwheat flour.

메밀분 30%와 강력분 70%의 복합분으로 강력분만을 사용한 이스트 발효빵과 유사하도록 메밀빵을 만들기 위하여 활성 글루텐과 gum 물질을 첨가하였으며 복합분의 제빵 적성에 미치는 그들의 효과를 알아보기 위하여 첨가물별 메밀빵의 물리적, 관능적 검사를 통하여 메밀빵의 품질 특성을 비교하였다. 메밀에 결여된 글루텐의 기능성을 보완하기 위하여 활성 글루텐과 gum물질을 첨가한 결과 메밀빵의 부피와 무게가 모두 증가하였으며 그 효과는 xanthan gum>활성 글루텐>guar gum 순 이었고, 단독 사용시보다는 활성 글루텐과 gum물질을 같이 사용하였을 때 효과가 더욱 증대되어 대조구 밀빵과 유사한 부피를 나타내었다. 빵 껍질색은 guar gum의 첨가로 L, a값이 증가하여 밝아졌고 xanthan gum을 첨가한 경우에는 L, b값이 감소하여 상대적으로 어두운 색을 나타내었다. 빵 내부색은 활성 글루텐과 xanthan gum 첨가로 L, b값이 감소하여 어두워졌다. 관능검사 QDA 결과 메밀빵에 활성 글루텐이나 gum 물질을 첨가함으로써 빵 속의 부서짐성이 유의적으로 감소되었고 그 밖의 탄력성, 촉촉함, 깔깔함 등의 조직감이 개선되었다. Amylograph에서 호화는 밀가루보다 메밀가루가 낮은 온도에서 일찍 시작되었고 최고 점도는 밀가루보다 메밀가루가 현저히 높았다. 메밀가루 30%와 강력분 70%의 복합분에 활성 글루텐과 gum물질을 간이 첨가함으로써 호화 점도가 감소되고 제빵 적성이 개선되었다. 또한 100% 강력분의 호화 점도쪽으로 낮아질수록 관능검사에서 메밀랑은 부드럽고 촉촉하게 나타났으며 부서지는 정도도 감소하였다. 이러한 관점에서 첨가물에 따른 메밀빵의 저장기간 중 노화변화에 대한 연구가 수행되어져야 할 것으로 사려된다.
