초록

본 연구는 밀가루의 일정량을 당진 특산물인 해나루 쌀가루를 10%, 30%, 50% 대체하여 제조된 식빵의 품질 특성을 알아보고자 진행되었다. 발효율, pH, 부피, 비용적, TPA, 영상분석, 색도, 기호도 검사, 특성차이 검사를 통하여 해나루 쌀가루를 첨가한 식빵을 분석하였다. 발효율은 60분까지는 대조구가 가장 좋았으나, 그 이후부터는 HRF 50 시료를 제외한 나머지 시료 간의 차이는 나타나지 않았으며, 반죽과 식빵 모두 해나루 쌀가루의 첨가량이 높을수록 pH가 높아졌고, 쌀식빵의 부피와 비용적은 감소하였다. TPA와 영상분석 결과, 쌀가루 첨가량이 많을수록 경도와 기공의 조밀도는 증가하였으며, 기공의 찌그러짐은 감소하였고, 색도는 해나루 쌀가루 첨가량에 따라 b값이 낮아졌다. 관능검사 결과 조직감과 풍미, 전체적인 기호도에서 대조구가 가장 좋은 평가를 받았으나, 외관은 HRF 30, 맛은 HRF 10이 대조구보다 더 좋게 평가되었으며, 세 시료 간 유의적인 차이는 발견되지 않아 결과적으로 해나루 쌀가루를 30%까지 첨가하여도 밀가루 식빵과 소비자의 기호도에서 큰 차이는 나타나지 않을 것으로 사료되었다.

This study investigated the quality characteristics of white pan bread with Haenaru rice flour which is regional product of Dangjin. Haenaru rice flour was substituted 10%, 30% and 50% for each bread sample. The overall effects of Haenaru rice flour substitution on pan bread were examined by investigating fermentation rates, pH, volume, specific volume, TPA, crumbScan and colorimeter and using sensory evaluation. A control showed the highest fermentation rate by 60 min, but there was no differences among all samples except HNR50 after 60 min. The higher Haenaru rice flour content, the higher pH value of bread loaf and bread and the lower volume and specific volume of rice breads. According to TPA and crumbscan, high amounts of Haenaru rice flour substitution increased the hardness of bread and decreased fineness and elongation of bread cells. In sensory evaluation, though a control got the best texture, flavor and overall acceptance, HRF30 and HRF10 showed the best preference of appearance and taste respectively, But most of all, there were no significant differences among those samples. Consequently, the results indicate that a substitution of Haenaru rice flour for wheat flour by 30 percent will not show any decisive difference in consumer's acceptance.
