초록

생리활성, 물성 및 관능적인 특성 등이 개선된 발효빵의 개발을 위하여 복합 생균제와 제빵효모의 적정 사용량 규명을 위한 연구를 수행하였다. 복합 생균제와 제빵효모(Saccharomyces cerevisiae)의 초기 사용량은 각각 1.5 : 0.1(Test 1군), 0.3 : 0.02(Test 2군), 0.15 : 0.01(g/g)(Test 3군)였다. 복합 생균제의 사용으로 반죽내의 생균제 균수는 44~642배 증가하였으며, 반죽의 pH는 산성화 되었다. 복합 생균제를 사용한 반죽의 pH와 비교시, 제빵효모를 사용하여 15시간 발효한 반죽의 pH는 상대적으로 높게 나타났다. 스타터균의 사용량을 달리한 세 가지 그룹들 중에서, 빵의 부피와 경도, 식빵껍질의 두께, 기공의 형태, 압박력 지수, 빵의 비용적 등에서 유의적인 차이가 없었다. 그러나, 관능평가에서는 발효빵의 향, 맛 및 전체적인 기호도는 Test 2군에서 유의적으로 높게 나타났다(p<05). 결과적으로, Test 1군과 Test 3군들보다 Test 2군에서 우수한 제빵특성을 보였다.

The principal objective of this study was to provide the basic information on the sourdough bread made with probiotics and yeast(Saccharomyces cerevisiae) and to establish an optimum formula for the development of sourdough bread with high physiological, textural and sensory quality characteristics. The following mixing ratios of probiotics and yeast were used: Test 1, probiotics: yeast = 1.5 : 0.1; Test 2, 0.30 : 0.02; Test 3, 0.15 : 0.01(g/g). Fermentatioin using sourdough resulted in increase in number of probiotics in sourdough by 244~642 times but reduced pH in sourdough. Contributions by yeast in pH in sourdough were not as high as probiotics after the first fermentation of 15 hrs period of the dough. Among the three groups, bread volume, crumb firmness, crumb thickness, crumb elongation, compression force value, and specific volume of bread of bread were not significantly different. However, in sensory evaluation, flavor, taste, overall acceptance in sourdough produced by Test 2 markedly improved(p<0.05). These results show that Test 2 bread had improved sourdough properties, compared to Test 1 bread and Test 3 bread.
