To develop and industrialize functional foods containing peanut sprout extract (PSE) and powder (PSP), the present study investigated the quality characteristics and antioxidant effects of breads prepared with 0, 0.5, 1, 2, 2.5, 5, 7.5, and 10% PSE and PSP. The expansion ratio of the dough, the quality characteristics such as volume, weight, specific volume, baking loss, color, texture, and sensory preference were evaluated. There were significant differences in the bread volume and specific volume among the control, PSE and PSP groups (p<0.001). Additionally, the weight and baking loss were decreased with an increasing amount of PSP (p<0.001). As the amount of PSE and PSP were increased, the L value of the crumb decreased, whereas the a and b values of the crumb significantly increased (p<0.001), suggesting that the crumb color of the bread may be significancy (p<0.001). As the amount of PSE and PSP increased, the hardness of bread significantly and rapidly increased from 5%. Meanwhile, there was no significance in springiness among the control, PSE and PSP groups. The total resveratrol content and DPPH free radical-scavenging activity of the bread significantly increased depending on the amounts of PSE and PSP (p<0.001). In the overall acceptance test, no significant differences were observed in the color, flavour, or texture, however, the taste and overall acceptance were significantly decreased between the control and the PSE group. All the sensory characteristics in the PSP group were significantly reduced compared with the control. Considering the above results, it can be expected that the suitable amount of PSE and PSP substituted for wheat flour will be from 1.0 to 2.5%. Furthermore, follow-up studies are being carried out continuously.

Purpose: Pomegranate has been reported to exhibit medical properties such as antimicrobial, antimutagenic, anticancer, and anti-inflammatory effects. Especially the pomegranate peel as a by-product of the juice industry possesses more polyphenols with an antioxidant effect than the pomegranate flesh does. This study aimed to investigate the effect of the pomegranate peel on the quality characteristics of steamed bread. Methods: Steamed bread containing pomegranate peel was prepared with 0%, 1%, 3%, 5%, and 7% replacements of wheat flour with pomegranate peel powder, respectively. Results: The pH of dough significantly decreased from 5.66 to 4.42 with the amounts of pomegranate peel powder rising. After a 1st fermentation, the pH of all groups decreased. With an increase of the pomegranate peel powder level, the fermentation tension decreased from 42.83 mL to 29.03 mL. In addition, the volume, the specific volume, and moisture decreased as the pomegranate peel powder content level heightened. For color, steamed bread added with 7% pomegranate peel powder displayed low lightness but high redness and yellowness. In texture analysis, hardness and chewiness of the steamed bread rose as the pomegranate peel powder content increased, while the springiness and cohesiveness declined. Both total polyphenol and DPPH radical scavenging activity significantly increased with growing levels of pomegranate peel powder. In a sensory evaluation, the group with 1% pomegranate peel powder added showed the highest sensory preference scores for color, flavor, chewiness, taste, and overall acceptability. Conclusion: The results of this study suggest that steamed bread prepared with the addition of 1% pomegranate peel powder is the most optimal product for appropriate quality characteristics.

As interest in health has recently increased, many researchers have investigated the utilization of functional foods by confectioneries and bakeries. However, research on loaf bread containing beets has not been conducted. To investigate the optimal ratio of beet in loaf bread containing beet powder, characteristics of loaf bread according to 2%(B2), 4%(B4), and 6%(B6) beet powder per wheat flour were examined. The experimental results were as follows. Fermentation rate was reduced as content of beet powder increased compared with the control, whereas pH levels of dough and loaf bread significantly increased as content of beet powder increased. As content of beet powder increased, volume of loaf bread decreased, whereas specific volume increased. There was no significant difference in volume of loaf bread between the samples. As far as color changes are concerned, as content of beet powder increased, L value decreased, whereas a and b values increased with significant differences between the samples. Characteristics were examined by sensory evaluation of loaf bread containing beet powder. Color of inner texture and peel color of loaf bread significantly increased as content of beet powder increased. Size of air pores was largest in B4, and there was no significant difference in the uniformity of loaf bread between the control and experiment groups. As content of beet powder increased, rigidity of bread was reduced. Control showed the highest elasticity, whereas moisture level was highest in B2 with no significant differences between the samples. The flavor of beet was stronger as content of beet powder increased. In the preference test, B4 showed the highest preference scores for texture, flavor, taste, and overall likeness but not appearance. The experimental results showed that B4 among all control and experimental groups had the most suitable baking characteristics and an optimum content of beet powder. Therefore, B4 can be considered as the most appropriate for making loaf bread containing 4% beet powder in terms of physical and sensory characteristics. This is a new product that satisfies overall sensory preferences and has improved functionality.

This paper investigated the effects of the percentages of yeast and fermentation time as well as the top and bottom temperature of oven on the baking properties of rice bread. The specific volume of the dough decreased as the amount of added yeast and fermentation time increased. When 1.5% yeast was added at 60 min of fermentation time, the shape of the rice bread showed the largest volume, high appearance and a round shape. The top and bottom temperature of the oven on the baking characteristics of rice bread were affected by the baking time. When the top and bottom temperature of the oven at 200 and $140^{\circ}C$, and 200 and $170^{\circ}C$, the baking time was 20 min. When the top and bottom temperature of oven at 140 and $170^{\circ}C$, the baking time was 40 min. When the top and bottom temperature of the oven were 170 and $170^{\circ}C$, the shape of the rice bread indicated the largest volume, high appearance and a round shape. The results of this study revealed that the replacement of rice flour with 1.5% yeast, 60 min of fermentation time, and the top and bottom temperature of oven at $170-170^{\circ}C$ are effective for rice bread.
