Abstract

This study was to investigate the quality characteristics of sourdough bread made with 4 kinds of kamut sour starter. Kamut sour starters were made according to dough yield of sour starter and yeast adding on sour starter. We exmanined pH level, fermentation rate, specific volume, CrumbScan, moisture content, color value, texture analyzer, shelf-life test and sensory evaluation for observing quality characteristics of sourdough bread. From the results of pH measurement, kamut sourdough breads had lower pH value in dough and crumb pH than CON. In the experiment of dough's fermentation rate, CON had the rapidest fermentation rate among the samples initially, but the experimental groups also expanded as much as CON grew in spite of its slow fermentation. Specific volume and CrumbScan results suggested that CON had the largest volume. In addition, CM and TM had smaller volume than Pool and Biga. The sample that had the highest moisture content was Pool because its sour starter had the most amount of water. In color value test, CON had lighter crumb and crust color than other specimens. As a result of the TPA and shelf-life tests, CON had the softest hardness after 24 hours. However, Pool had similar hardness with CON after 72 hours. The result of the acceptance test of sourdough breads indicated that people prefered Pool and Biga to TM and CM. Difference test showed similar results with prior experiments. As the final outcome, Poolish was chosen as the optimal formula for kamut sour starter.

본 연구는 카무트 사워종 제조 방식을 달리하여 제조한 사워도우 식빵의 품질 특성을 알아보고자 반죽의 pH와 발효율, 비용적, 영상분석, 수분함량, 색도, TPA, 저장성, 기호도 검사를 실시하였다. 반죽의 pH의 경우, 카무트 사워종을 첨가함으로써 대조구보다 유의적으로 낮은 pH를 가지는 것을 확인하였으며, 발효율 측정을 통해 사워종을 첨가한 시료의 발효가 대조구보다는 다소 느리지만, 대조구와 동일한 부피만큼 팽창하는 것을 알 수 있었다. 비용적과 영상분석 결과, 사워종을 첨가한 실험구가 CON보다는 다소 작은 부피를 가지며, 실험구 중에서도 TM과 CM의 부피와 비용적이 유의적으로 낮음을 확인하였다. 수분함량은 사워종의 수분함량이 높을수록 최종 제품의 수분함량도 높아지는 경향을 보여, Pool의 수분함량이 가장 높게 나타났다. 색도 분석 결과, 카무트 자체의 색으로 인해 카무트 사워종을 첨가한 실험구에서 다소 어두워지는 것을 알 수 있었다. TPA과 저장성 측정 결과, 시료 제조 24시간 후 시료의 경도는 CON이 유의적으로 가장 낮았으나, 72시간 경과할 때는 Pool과 CON은 유의적인 경도 차이가 없어짐을 확인하였다. 관능검사 중 기호도 검사 결과, 실험구 중에서는 이스트가 소량 첨가된 Pool과 Biga가 높은 평가를 받았고, TM과 CM은 전체적 기호도에서 좋지 않게 나타났다. 특성 차이 검사결과, 카무트 사워종을 첨가함으로써 부피는 다소 감소하지만, 빵의 속질과 껍질 색은 더 진해지며, 신맛과 곡물 풍미를 향상시킬 수 있음을 확인하였다. 전반적인 품질특성 결과와 관능검사 결과에 따르면, Poolish의 형태로 카무트 사워종을 제조하는 것이 사워도우 빵의 품질과 기호도 측면에서 최적으로 여겨진다.
