  • Mulberry fruit powder was substituted for wheat flour in pound cake recipes in amounts of 0%(control), 5%, 10%, 15%, and 20%. We measured the specific gravity of the dough, specific loaf volume, dough yield, baking loss, moisture content, pH, color, identified the texture, and conducted a sensory evaluation for each pound cake. Moisture content increased according to the amount of mulberry fruit powder, but specific gravity, dough yield, and pH decreased. Specific loaf volume and baking loss increased as the amount of mulberry fruit powder increased, but not considerably. The chromatic 'L' and 'b' values were reduced as more mulberry fruit powder was added to more pound cake, While the chromatic 'a' value increased. Texture hardness, springiness, gumminess and chewiness decreased as the pound cake contained more mulberry fruit powder. Cohesiveness did not show any considerable differences beteeen the cakes. A sensory evaluation showed a high preference for the pound cake made with 10% mulberry fruit powder.

  • This study assessed the preparation and quality characteristics of cookies prepared from Taraxacum coreamm powder (TCP) (0, 2, 4, 6, 8%) substituting wheat flour. The pH of the cookie dough significantly decreased with increasing TCP. However the density of the cookie dough was not significantly different among the test groups. The baking loss rate of the groups with TCP was slightly lower, whereas the moisture content was higher than the control group. The spread factor of the cookies decreased significantly with increasing TCP. The hardness of the cookies increased as TCP increased. In Hunter's color value, the L and a value of the cookies decreased with increasing TCP, while the b value increased. The DPPH radical scavenging activity of the cookies significantly increased with increasing TCP. Based on the above results, this study suggested that TCP can be a good ingredient to increase the functionality of cookies.

  • This study investigated the effects of freeze-dried sweet pumpkin powder on the baking of bread. Freeze-dried sweet pumpkin powder (0, 3, 6, 9, or 12%) was supplemented during the baking process and the bread volume, weight, specific volume, baking loss rate, texture, and sensory characteristics were measured. The results were following. Freeze-dried sweet pumpkin contained 4.88% water, 4.40% protein, and 4.02% ash. The L-values (brightness) of the bread were significantly lower as increasing amounts of sweet pumpkin powder were added (p<0.001). However, higher values for the a-value (redness) and b-value (yellowness) were observed (p<0.01 for both values). The volume and baking loss rate decreased when the sweet pumpkin powder was added. In contrast, the weight significantly increased as sweet pumpkin powder was added (p<0.01) and the intensity of dark brown color increased. The outer side of the bread was balanced overall, but the outer skin of the bread appeared darker as the amount of sweet pumpkin powder increased. The overall acceptability, hardness (p<0.001), elasticity (p<0.01), cohesiveness (p<0.01), gumminess (p<0.01), and brittleness (p<0.001) increased as sweet pumpkin powder increased as well. However, when sweet pumpkin powder was added at 12%, the overall acceptability value was fairly low. Sensory parameters, such as taste (p<0.001), color (p<0.001), and flavor (p<0.05) were observed when sweet pumpkin powder was used at 3% and these results were lower than the control. Overall acceptability (p<0.001) was best when sweet pumpkin powder was used at 9% and the texture was best when sweet pumpkin powder was used at 6%.

  • This study was carried out to investigate the effect of pastry margarine content and number of layers on moisture content, baking loss, specific loaf volume and the vapor action in the manufacturing process of puff pastry. As the number of layers of the puff pastry increased the moisture content of the products slightly increased. And the moisture contents of the products decreased, as the pastry margarine contents of the puff pastry increased in the same number of layers. The baking loss of the products tended to decrease as the number of layers increased. On the other hand, as the pastry margarine contents of the puff pastry increased, the baking loss of the product increased. When the pastry margarine content in puff pastries became 130%, 81 layers provided the maximum specific loaf volumes $21.62{\pm}0.79\;ml/g$ of puff pastries. When 110% of margarine and 256 layers were applied for preparation of puff pastry, the number of vapor action was $8.25{\pm}0.50$ with the vapor action size of 9-15 mm.
