초록

본 연구는 기능성 성분들이 함유하고 있는 꾸지뽕잎 분말 첨가에 따른 식빵의 품질 특성을 알아보고자 진행하였다. Mixograph, pH, TPA, 부피, 비용적, 수분, 영상분석, 색도, 기호도 검사, 보존성 검사를 통하여 꾸지뽕잎 분말을 첨가한 식빵을 분석하였다. Mixograph를 측정 결과, 꾸지뽕잎 분말을 첨가한 반죽은 제빵 적성에 적합하였다. 꾸지뽕잎 pH의 경우 분말의 첨가량이 많아질수록 pH는 높아졌으며, 1차 발효 후와 식빵의 pH는 첨가량이 많을수록 낮아졌다. TPA 분석결과, 꾸지뽕잎 분말 첨가량이 높아질수록 경도, 씹힘성, 검성은 높아졌으며, 탄력성, 응집성, 탄성은 유의적인 차이가 없었고, 꾸지뽕잎 식빵의 부피와 비용적은 감소하였다. 영상분석 결과 기공의 조밀도, 껍질의 두께, 크기는 첨가량이 많아질수록 유의적인 차이를 보여주었으며, 색도는 꾸지뽕잎 분말의 첨가량에 따라 L값은 어두워졌다. 기호도 검사 결과, 외관과 조직감은 CLP3가 대조구보다 좋았으며, 맛과 전체적인 기호도는 CLP2가 대조구보다 더 좋게 평가되었다. 보존성 측정 결과, 경도는 24, 48, 72시간 동안 모두 꾸지뽕잎 분말 1∼2% 첨가한 시료가 대조구와 유의적인 차이를 보이며 경도가 낮았으며, 적은 양의 꾸지뽕잎 첨가가 식빵 속질의 부드러움을 유지하는데 좋은 것으로 사료되며, 수분함량이 낮아지긴 하였으나, 대조구와 유의적인 차이가 없었다.

This study was conducted to investigate quality characteristics of white pan bread with Cudrania tricuspidata leaf powder having functional components. Mixograph, pH, TPA, volume, specific volume, moisture, CrumbScan, color value, sensory evaluation and shelf-life test were performed on the white pan bread with Cudrania tricuspidata leaf powder. The obtained results are as follows. Mixogram analysis results showed that the dough with Cudrania tricuspidata leaf powder was suitable for baking quality. The more Cudrania tricuspidata leaf powder was added in the dough, the higher dough pH was and the lower pH values after fermentation and of the final productwere. TPA analysis results showed that higher amounts of Cudrania tricuspidata leaf powder resulted in increased hardness, chewiness, and gumminess of the white pan bread. Volume and specific volume of white pan bread were decreased with increased amounts of Cudrania tricuspidata leaf powder. CrumbScan images showed that fineness of grain, crust thickness, and volume of the bread were significantly different depending on the amount of Cudrania tricuspidata leaf powder. While color value analysis showed that increasing the amount of Cudrania tricuspidata leaf powder resulted in low L and a values. The results of the acceptance test showed that CLP3 had better scores in the appearance and texture characteristics than the control, while taste and overall acceptance were higher in the CLP2 compared with the control. According to the results of the shelf-life test, the white pan bread with 1∼2% of Cudrania tricuspidata leaf powder had a significantly lower hardness when compared with the control. It was judged that a lower amount of Cudrania tricuspidata leaf powder could help in maintaining the softness of bread crumbs. Moisture content in the white pan bread decreased with the increased amounts of Cudrania tricuspidata leaf powder, but there were no significant differences among specimens.
