To make soft and less stale bread, various amounts of gelatinized wheat flour dough were added for making pan bread. In the dough process, higher gelatinized wheat flour dough showed higher consistency and dough development time but a lower dough stability time. Expansion during fermentation represented the highest value upon addition of 10% gelatinized wheat flour dough (GWFD), and this value decreased with increasing amount of gelatinized wheat flour dough. Volume of bread was the highest in the control and lowest in 30% GWFD, and there was no difference between 10% GWFD and 20% GWFD. Moisture contents of bread made with various amounts of gelatinized wheat flour dough increased with increasing gelatinized wheat flour dough amount. Color values of bread made with various gelatinized wheat flour dough were not significantly different. Chewiness, brittleness, and hardness of bread made with control and 10% GWFD showed low values, whereas bread made with 20% GWFD and 30% GWFD showed high values. During storage, chewiness, brittleness, and hardness increased with increasing storage period in whole breads, whereas breads made with 10% GWFD showed the lowest increasing rate. In the sensory strength test, chewy texture increased upon addition of gelatinized wheat flour dough. In the consumer acceptance test, 10% GWFD showed the most overall acceptance. In conclusion, bread made with 10% gelatinized wheat flour dough is desirable for increasing softness and decreasing bread staling.

In this study, the fermentative characteristics of rye sourdough fermented with Omija extract were investigated. The pH and total titratable acidity, numbers of yeast and lactic acid bacteria, and expansion rate were measured. While the pH of Omija rye sourdough decreased from 5.60 to 3.86, the total titratable acidity significantly increased from 2.39 to 8.50 with fermentation time (p<0.05). The numbers of yeast and lactic acid bacteria significantly increased for 18 h of fermentation period (p<0.05). The expansion rate of Omija rye sourdough showed a maximum of 183%, more than 47% more than the highest value of rye sourdough (129%). These results suggest that the application of Omija extract for making sourdough could be a good way to decrease the sanitary risk especially for early stage of sourdough fermentation. In addition, Omija rye sourdough could contribute to improvement of baking quality such as volume increase and flavor improvement of rye bread.

This study attempted to examine the effects on sensory characteristics and texture of Kyongdan in various volume of adding water and number of kneading in the preparation of Kyongdan. Evaluation was conducted through sensory evaluation and objective evaluation. The results were summarized as follows. 1. In sensory evaluation on the various volume of water and unmber of kneading, the most favorite tendency on the overall guality was at the 25% addition water and over 50 times kneading with glutious rice powder. 2. This condition corresponded to the low level of hardness, gumminess, chewiness and the high level of springiness and cohesiveness in comparison with Instron measurement.

This study was carried out to investigate the possibilities of adopting xanthangum, guargum and ${\kappa}-carrageenan$ as cryprotectant by examining the rheological and structural properties of dough. Results of farinography showed that water absorption, development time and mechanical tolerance index in dough with the gums increased more than those of the control. It was also found that resistance in dough with the gums increased greatly, but extensibilities were similar to that of the control, resulting in increasing R/E values in the dough with the gums through extensograph. According to amylogram, gelatinization temperature of dough was $59.5^{circ}C$ and those of the dough with the gums were $58^{circ}C$. Even though maximum viscosity of the dough was 550 B.U in the control, those were 690 B.U, 780 B.U and 760 B.U in the dough with xanthangum, guargum, and ${\kappa}-carrageenan$, respectively. The control deeply increased the pH during frozen storage but the addition of ${\kappa}-carrageenan$ and xanthangum increased the pH slightly. The dough with the gums had more stable spaces than control in the microstructure through SEM.

The rheological properties of dough made with 0% 1 % 2% or 3% Corni fructus flour were investigated Rapid Visco Analyzer (RVA) analysis showed that the initial pasting temperature increased with increasing Corni fructusflour content, while the peak viscosity decreased. The water absorption, stability, development time, elasticity and valorimeter value of the dough, as determined using a farinograph and alveograph, decreased with increasing amounts of Corni fructusflour, while weakness increased. The extensibility, fermented volume and consistency of the dough increased gradually with increasing Corni fructus flour content. These results indicate that the addition of Corni fructus flour affects the rheological properties of bread.

메밀가루를 이용한 빵을 만들기 위하여 밀가루에 메밀가루를 10,20,30%를 혼합한 반죽과 30% 메밀복합분에 글루텐, ascorbic acid 및 HPMC를 혼합한 반죽들의 amylogram, farinogram 및 extensogram의 특성을 측정하였으며 SEM을 이용한 반죽의 구조도 관찰하였다. Amylograph에 의한 호화개시온도, 최고점도 및 최고점도시의 글루텐, ascorbic acid 및 HPMC의 의해 감소하는 경향이었다. Farinograph에 의한 흡수량은 메밀가루의 참가량이 많을수록 약간씩 감소하였고, 글루텐을 첨가하였을 경우에는 증가하였으나 HPMC에 의해서는 오히려 감소하였다. 반죽형성시간은 메밀가루의 혼합비율이 높을수록 점차 짧아졌고 첨가제에 의해서는 증가하였다. Extensograph에 의한 발효특성은 메밀가루의 첨가량이 많을수록 신장도와 신장에 대한 저항도는 감소하였으나 첨가제사용에 의해 증가하였으며 특히 글루템에 의해 신장저항도와 반죽의 강도가 높게 나타났다. 또한 SEM에 으한 반죽의 구조는 메밀가루의 혼합비율이 높아질수록 규칙적인 protein matrix를 형성하지 못하고 구형의 큰 전분입자와 작은 전분입자들이 엉겨서 덩어리진 상태로 혼합되어 있었으며 첨가제에 의해 전분입자와 단백질matrix 상호간에 결합상태가 개선되었으며 특히 첨가제 중 글루템은 밀가루 반죽과 유사하였으므로 빵의 부피 및 제빵성을 향상시켜 줄 것으로 생각된다.

효모와 젖산균에 의해 발효된 소위 sourdough빵은 천연의 고유 향미와 그리고 건강식품이라는 인식과 더불어 계속 소비가 증가되고 있는데, 이것은 젖산균에 의해 생성된 젖산과 아세트산에 의해 약간의 신맛과 독특한 풍미가 제공되고 저장성이 향상되기 때문이다. 이에 본 연구에서는 냉동 빵의 품질 향상을 목적으로 sourdough의 냉동반죽 특성을 조사하였다. soudough용 wheat brew 제조에는 L.plantarum과 Lbrevis혼합균주(0.1%)의 발효상태가 양호하였으며 wheat brew를 첨가한 경우 farinouam 특성중 반죽의 stability가 감소되어 반죽의 발효시간이 단축된 short time법을 반죽제법에 적용하였다.

증편반죽의 발효에 따른 해면상의 조직(망상구조)형성능의 mechanism을 조사하기 위하여 반죽의 구성성분의 경시적 물성 및 효소(diastase 및 protease) 활성의 변화, 구성 전분 분획의 glucose chain length 변화 및 1% SDS에 의해서 용출되는 단백질 분획의 변화에 대해서 검토하였다. 발효가 진행됨에 따라 증편반죽의 pH는 감소한 반면 점성 및 부피는 발효경과 10시간가지 증가하다가 그 이후로는 약간 감소하는 경향을 보였다. 발효의 진행과 더불어 diastase의 활성은 증가하였으며, 쌀전분 분획 중 amylose의 함량은 약간 감소하였다. 그리고 전분분자의 $\alpha-1,6-glucoside$ 결합을 isoamylase(debranching enzyme)로 가수분해시킨 후 Sephadex G-75를 이용한 chromatogram 분석에 의하면 쌀가루 전분 분획과 증편반죽 전분 분획의 glucose chain length 분포는 거의 유사하지만 발효가 진행됨에 따라 중합도가 낮은 부분이 우선적으로 diastase의 작용을 받은 것이라고 생각되어진다. 한편, 발효가 진행된에 따라 protease의 활성은 증가하고 있었음에도 불구하고 증편반죽의 당에 의한 단백질 분획의 고분자화가 Suprose CL-12 column chromatogram 상에서 관찰되었는데, 이것은 아마도 발효과정 중 증편반죽에 공존하는 미생물들의 발효산물인 당질(gum질)을 매개로 한 단백질 분자의 회합에 의한 결과라고 생각되어진다. 따라서 이러한 결과를 미루어 볼 때 증편반죽의 망상구조 형성능은 발효과정 중 일어나는 당과 단백질간의 상호작용에 의한 결과라 생각되어진다.
