Abstract

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.

부드럽고 노화를 지연하는 빵을 제조하기 위해 호화밀가루반죽을 다양한 농도로 첨가하여 제빵 하면서 제빵특성 및 저장성을 분석하였다. 호화밀가루반죽을 첨가하여 반죽특성을 분석하였을 때 견도는 호화밀가루반죽 함량이 증가할수록 높은 경향을 나타내었으며, 반죽형성시간은 호화밀가루반죽의 양이 증가할수록 증가하는 경향을 나타내었고, 반죽의 안정도는 호화밀가루반죽의 양이 증가할수록 짧아지는 경향을 나타내어 호화밀가루반죽의 양이 증가할수록 gluten 형성 능력은 약화되는 것을 알 수 있었다. 가장 발효 팽창력이 높은 것은 10% 호화밀가루반죽을 이용하여 반죽하였을 경우였으며 호화밀가루반죽 첨가량이 많을수록 낮은 발효 팽창력을 나타내었다. 식빵의 부피는 대조구가 가장 큰 것을 알 수 있었고 10%와 20%의 호화밀가루반죽을 첨가하여 제조한 식빵의 부피는 통계적으로 유의차가 없었으며, 30% 호화밀가루반죽을 첨가하여 제조한 식빵의 부피는 가장 작은 것을 알 수 있었다. 호화밀가루전분 함량을 달리하여 제조한 식빵의 수분 함량은 제조 당일에는 호화밀가루반죽을 이용하여 제조한 식빵보다 높은 경향을 나타내었다. 저장기간 중 수분 함량의 변화는 호화밀가루반죽을 첨가하여 제조한 식빵은 호화밀가루반죽 첨가량이 많을수록 수분 함량은 더 높아지는 경향을 나타내었으며, 저장기간 동안 수분 함량의 감소율은 낮았다. 색도는 각 저장기간에 따라 통계적 유의차가 없음을 알 수 있었다. 제빵 직후 씹힘성, 깨짐성과 경도는 대조구와 10% 호화밀가루반죽을 첨가하여 제조한 빵이 낮은 값을 나타내었다. 저장기간 동안 씹힘성, 깨짐성과 경도는 저장기간에 따라 증가하는 경향을 보였으며 2일 저장 시까지는 10% 호화밀가루반죽을 첨가하여 제조한 빵의 증가폭이 가장 적었다. 관능특성 강도 평가 결과 호화밀가루반죽을 이용하여 제빵 하였을 때 쫄깃한 조직감이 증가하는 것을 알 수 있었으며, 소비자 기호도 조사결과 호화밀가루반죽을 첨가하여 제조한 식빵이 조직감 및 전반적인 기호도가 더 높게 평가되었으며 전반적인 기호도에서 10% 호화밀가루반죽을 첨가하여 제조한 빵을 가장 선호하는 것을 알 수 있었다. 결론적으로 너무 많은 호화밀가루반죽의 첨가는 제빵 적성을 향상시키는 데 큰 영향을 미치지는 못했지만 10% 호화밀가루반죽의 첨가는 좋은 물성과 기호성을 나타내며 노화속도를 줄이는 데 영향을 줄 수 있는 제빵 방법임을 알 수 있었다.
