  • For the consumption extension of Chinese artichoke(Stachys sieboldii MIQ), the quality characteristics and sensory evaluation of white pan bread prepared with different levels of added Chinese artichoke powder(0, 3, 6, 9, and 12%) were investigated. Volume changes of dough, moisture contents(p<0.001), and baking loss rate(p<0.001) decreased with increasing levels of Chinese artichoke powder. In addition, with an increase in the level of Chinese artichoke powder, the volume and specific volume of white pan breads significantly decreased(p<0.001 and p<0.001, respectively) whereas the weight of white pan breads significantly increased (p<0.001). In terms of color, the lightness(L) decreased, but the redness(a) and yellowness(b) increased with increasing Chinese artichoke powder levels(p<0.001). From the texture profile analysis(TPA) of white pan breads, hardness, chewiness(p<0.05), gumminess(p<0.001), and adhesiveness(p<0.001) increased whereas springiness and cohesiveness(p<0.01) decreased according to the levels of added Chinese artichoke powder. In the attribute difference test, crumb color(p<0.001), grain size(p<0.05) decreased whereas grain uniformity, yeast flavor, acridity flavor(p<0.001), plainer taste(p<0.05), sweet taste(p<0.01), acridity taste(p<0.001), firmness, springiness, moistness, softness, and chewiness increased in accordance with levels of added Chinese artichoke powder. Overall acceptability showed that the sample containing 9% Chinese artichoke powder had the highest score (p<0.001). As a result, the optimal ratio of Chinese artichoke powder for white pan bread was determined to be 9%.

  • The effects of Angelica gigas nakai powder on bread quality during storage period were evaluated. Breads were prepared by the addition of 0, 0.5, 1, 2, 3, 5 and 10% of Angelica gigas nakai powder to flour of the basic formulation. The moisture, crude protein, crude fat and crude ash contents of the bread decreased by increasing amounts of the Angelica gigas nakai powder were the lowest in the control group. There were no significant difference in pH of the bread among each experiment groups. The weight of bread increased with increasing Angelica gigas nakai powder concentration, while the volume of dough decreased. In color values, with increase of Angelica gigas nakai powder concentration, L value decreased in the crust and crumb, but a and b values increased. As the results of texture, hardness, gumminess and chewiness were increased with increase of Angelica gigas nakai powder concentration, but adhesiveness, springiness and cohesiveness were decreased. Softness in the crumb stored for 1 or 7 days was the highest for the bread made with 2% Angelica gigas nakai powder, and chewiness was the lowest for the bread made with 5% Angelica gigas nakai powder. The water activity in the bread stored for 3 days was the highest for the breads made with 2% and 3% Angelica gigas nakai powders. After 7 days, the water activity tended gradually to decrease. In the results of sensory evaluation, the quality of the 0.5% or 1% Angelica gigas nakai powder bread showed the highest in taste and flavor. The color, taste, flavor, appearance, texture, and overall acceptability of the bread decreased with the increasing Angelica gigas nakai powder content. Considering the able outcome, the addition of Angelica gigas nakai powder by 0.5% and 1% is thought to play a role as a functional breads, along with the improvement of quality.

  • This study was carried out to evaluate the quality characteristics of white pan breads containing 0.5% of gums, including HPMC, MC and SA. Moisture content, water activity, cooling loss, bread volume, rheological, and sensory evaluations were performed to examine the bread quality characteristics. Moisture content and water activity were highest in the bread with added HPMC. HPMC showed the smallest cooling loss among the breads compared to the other added gums. The bread with added SA had the thelargest volume at $2,560{\pm}24$ mL. In terms of rheological properties, the hardness of the bread containing HPMC was lowest and the springness of the bread with added SA was the highest. In sensory evaluations, the bread containing HPMC was evaluated as the most preferred product by acquiring the highest scores in internal and external evaluations. Consequently, the bread containing 0.5% SA showed better volume and springiness values. However, the bread containing 0.5% HPMC showed greater moisture content, greater water activity, lower cooling loss, and better sensory evaluation scores. Based on the overall results, HPMC was considered to be the most effective hydrocolloid to increase bread quality.

  • 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.
