  • The purpose of this study was to determine the optimization mixing ratio of wheat sprout powder (WSP) and hemicellulase for the preparation of white pan bread. Using a response surface methodology, independent variables were WSP and hemicellulase. Dependent variables were physicochemical properties, antioxidant properties and sensory evaluation. Water binding capacity of dough increased with increasing WSP. Color value showed positive correlations with WSP. L value decreased and a, b values increased as WSP increased. The adjusted determination coefficient of texture analysis was calculated to be 0.7230~0.9446 having the p-value less than 0.1. Specific volume of bread showed a positive correlation with hemicellulase and a negative correlation with WSP. DPPH radical scavenging activity and total polyphenol were represented by a linear model and showed positive correlations with WSP. Sensory evaluation were represented by a quadratic model. In conclusion, the optimal formulation for WSP added bread, as assessed by numerical and graphical optimization methods, was WSP 2.36%, hemicellulase 0.069% per wheat flour 100 g. The above results indicate that WSP can be used as health-oriented material in the bread industry. This is also expected to meet demands of consumers who are in the pursuit of healthy food.

  • Yacon (Smallanthussonchifolius) is a root crop that contains high amounts of fructo-oligosaccharides (FOS). FOS has a sweet taste, is low in calories, and is known to promote intestinal tract health. In this study, various yacon concentrates were substituted for sugar in white pan bread to obtain healthy benefits from the use of FOS. The quality characteristic changes during storage of the white pan breadswith 0, 25, 50, 75 and 100% of added yacon concentrates instead of sugar were investigated. During storage, the water contents and water activities of the breads made with high amounts of yacon concentrates changed less than in those made with only sugar. The hardness and chewiness of the breads made with high amounts of yacon concentrates had lower values than those made with only sugar. Thus, bread made with yacon concentrates might exhibit increased moisture retention and decreased aging velocity. The substitution of yacon concentrates for sugar in pan bread improved the bread quality.

  • This research is about the quality characteristics of white bread mixed with varying ratios of Seomcho powder, such as 1%, 3%, 5%, and 7% (Spinacia oleracea L.). The pH level of dough decreased as more Seomcho powder (Spinacia oleracea L.) was added, and 7% addition recorded the lowest pH. The fermentation power of dough expansion decreased as the additional ratio increased in both the first and second proofing, and it was negatively correlated to the fermentation time factor. The moisture content of bread decreased as the addition ratio increased. The bread volume became smaller as the addition ratio increased, but it correlated negatively with its specific volume. The color of the crumb, the lightness and redness decreased in comparison to the control, but the yellowness increased. The total amino acid contents increased as the addition ratio increased, and glutamic acid was positively correlated to the additional ratio. The total free amino acids increased as the additional ratio increased, but cysteine levels were high at 5% and 7% additional ratio. The textural characteristics of the bread, springiness and cohesiveness were lower than the control, but gumminess, brittleness, and hardness were higher than the control. The adhesiveness was realized at 7% additional ratio.

  • In this study, domestic wheat white breads were prepared with the substitution of 1.5, 3.0, 4.5, and 6.0% Nelumbo nucifera G. tea powder(NNTP). The samples and a control were then compared with regard to quality characteristics, including pH, total titratable acidity, fermentation power of dough expansion, specific volume, baking loss, moisture content, color, textural characteristics, external and internal surface appearances, and sensory qualities in order to determine the optimal ratio of NNTP in the formulation. As the NNTP contents increased, the pH of dough and bread, baking loss, and lightness decreased, whereas the total titratable acidity of dough and bread increased. The fermentation power of dough expansion increased with increasing incubation time. The NNTP samples evidenced significantly higher specific volume, greenness, yellowness, resilience, and crumb consistency than were observed in the control group. However, hardness and fracturability evidenced the opposite effect. The water content and uniformity of the crumb pores were highest at a substitution level of 1.5%, and were lowest at a level of 4.5%. Crumb color, flavor, and delicious taste decreased with increasing NNTP contents, whereas lotus leaf flavor, astringency, bitterness, and off-flavor increased. Density of the crumb pore and crumb springiness were not significantly different among the samples. Softness, chewiness, and overall acceptability were maximal with the 1.5% substitution, and were minimal in the 6.0% group. In conclusion, our results demonstrate that $1.5{\sim}3.0%$ NNTP may prove quite useful as a substitute for domestic wheat flour in the production of white bread, and may evidence favorable nutritional and functional properties.

  • 양배추 분말을 첨가한 건강 기능성 식빵을 제조하기 위해 밀가루에 양배추 분말을 2.5%~10% 첨가하여 반죽에 대한 물성, 제빵적성 및 관능적 특성을 조사하였다. 첨가한 양배추 분말의 양이 증가할수록 식빵의 색도는 L값은 유의적으로 저하하였고, a값과 b값은 양배추의 첨가량에 따라 증가하는 경향을 나타내었다(p<0.05). 양배추 분말의 첨가에 의해 반죽의 pH값과 제조한 빵의 무게는 증가하였고, 빵의 부피와 비용적 및 굽기 손실률은 감소하였다. 양배추 분말을 첨가하는 양을 증가시킬수록 경도는 유의적으로 증가하였으며, 관능검사 결과 전체적인 기호도에서는 대조구와 2.5%, 5.0% 첨가구 간에는 유의적 차이는 없었으나 맛에서 대조구의 기호도가 다소 높은 것으로 나타났다(p<0.05) 이상의 결과에서 양배추 분말을 제빵공정에 첨가하는 것은 빵의 색, 부피 등 식빵의 물리화학적 특성의 변화를 가져오는 문제점이 있었다. 그러나 대조구와 비교했을 때 식빵 제조시 양배추를 5%까지 첨가하는 것은 관능적 특성에는 의미 있는 영향을 주지 않았다.
