Abstract

This study investigated color barley powder substituted for wheat flour in bread recipes with the amounts of 0%, 5%, 10%, 15% and 20%. Color barley powder consisted of 9.35% of moisture content, 9.37% of crude protein, 1.64% of crude fat and 2.96% of crude ash. Water soluble dietary fiber is 3.21, insoluble dietary fiber is 4.91, total dietary fiber content is 8.12, and ${\beta}$-glucan is 49.31. DPPH radical scavenging activity is 56.76%, total phenol content is 234.34. The farinograph measurement result of the bread made with color barley powder showed that consistency, water absorption, development time and time breakdown have decreased. The alveogram measurement result of the bread made with color barley powder showed that overpressure, extensibility, swelling index and deformation energy have increased. The amylograph measurement result of the bread made with color barley powder showed that peak viscosity, hot past viscosity and breakdown have decreased. Baking loss and specific loaf volume have decreased as the color barley powder content increased. The chromaticity measurement result showed that the 'L' and 'b' of bread have increased as the color barley powder content increased, while the chromatic 'a' value increased. The texture measurement result showed that the hardness and gumminess of bread have increased as the color barley powder content increased. cohesiveness, springiness and chewiness have decreased. Overall preference scores showed a high overall acceptability for the bread made with 10% color barley powder.

본 연구에서는 기능성 물질이 함유된 유색보리와 유색보리 분말을 첨가한 식빵 반죽 및 식빵을 제조하여 이화학적, 관능적 특성을 첨가량을 달리하여 측정하였다. 유색보리 분말의 수분함량은 9.35%, 조단백은 9.37%, 조지방은 1.64%, 조회분은 2.96%로 나타났다. 수용성 식이섬유 함량은 3.21 g/100 g, 불용성 식이섬유 함량은 4.91 g/100 g, 총 식이섬유 함량은 8.12 g/100 g으로 나타났고, ${\beta}$-glucan 함량은 49.31 mg/g으로 나타났다. DPPH radical 소거능은 56.76%로 나타났고, 총 페놀 함량은 234.34 mg/100g으로 나타났다. 유색보리 분말을 첨가한 식빵 반죽의 farinograph 측정 결과 consistency, water absorption, development time, time breakdown은 첨가량이 증가할수록 감소하였고, tolerance index는 첨가량이 증가할수록 증가하였다. Alveogram 측정 결과 overpressure P값, extensibility L값, swelling index G값, deformation energy W값은 첨가량이 증가할수록 감소하였다. Amylograph 측정 결과 pasting temp. T값은 첨가량이 증가할수록 증가하였고, peak viscosity P값, hot past viscosity H값, breakdown P-H값은 첨가량이 증가할수록 감소하였다. 유색보리 분말을 첨가한 식빵의 굽기 손실률, 비용적은 첨가량이 증가할수록 감소하였다. 색도 L값, b값은 첨가량이 증가할수록 감소하였고, a값은 첨가량이 증가할수록 증가하였다. 유색보리 분말 첨가한 식빵의 texture 경도, 점착성은 첨가량이 증가할수록 증가하였고, 응집성, 탄력성, 씹힘성은 첨가량이 증가할수록 감소하였다. 기호도는 맛, 부드러움, 씹힘성은 10% 첨가군이 높게 나타났고, 전반적인 기호도도 10% 첨가군이 5.04로 가장 높게 나타났다.
