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 study is performed to examine the functional and quality characteristics of glutinous barley Jeung-pyun added with beet powder. Jeung-pyun is being prepared with concentration of 0, 2, 4, 6 and 8% (w/w) of the beet according to nonglutinous rice powder weight. The pH level of Jeung-pyun batters decrease along with fermentation time. However, the pH level of Jeung-pyun is higher than that of the Jeung-pyun batter. For hunter's color value of glutinous barley Jeung-pyun added with beet powder, the L (lightness) values decrease with increasing concentrations of beet powder, whereas a (redness) values increase (p<0.001). In the texture analysis, the hardness, chewiness and gumminess are significantly increased with the amount of glutinous barley Jeung-pyun with added beet powder. According to sensory evaluations, the appearance, color, flavor, taste, texture and overall quality are considered very good in the 4% of added beer powder in glutinous barley Jeung-pyun (p<0.001). The antioxidant activities of beet powder by DPPH free radical scavenging activity, ferric reducing antioxidant power and total phenolic contents are being recorded at $259.52{\mu}{\ell}/mg$, $0.44{\pm}0.01$, $15.29{\pm}0.04mg$ GAE/g respectively. The antioxidant activities of glutinous barley Jeung-pyun added with beet powder increase with increasing concentrations of beet powder. These results suggest that beet powder are useful as functional food resources within antioxidant activities.

The purpose of this study was to assess red beet as a natural colorant in emulsified pork sausage and to investigate the effect of red beet on quality characteristics of emulsified pork sausage during 20 d of cold storage. Red beet was prepared as a powder and a substitute with sodium nitrite at 0.5% and 1.0% levels in emulsified pork sausage. Red beet significantly increased the moisture content and pH (p<0.0001) and affected color traits. Lightness of emulsified pork sausage decreased by the addition of red beet powder (p<0.01), whereas lightness with red beet treatments slightly increased during 20 d of cold storage at $4^{\circ}C$ (p<0.05). Redness dramatically increased with red beet powder (p<0.0001). Color by sensory evaluation also showed a significant effect from red beet addition (p<0.05), whereas the other sensory properties such as flavor, tenderness, juiciness, and overall acceptability were not affected by the addition of red beet powder (p>0.05). Texture and 2-thiobabituric acid reactive substance were also not affected by red beet addition (p>0.05). Therefore, red beet could be a good natural colorant in emulsified pork sausage but it needs additional processing, such as betalain concentration and extraction as a juice, to be used as an antioxidant in meat products.

This study was conducted to develop an optimal composite recipe for nutritional cookies containing beet powder. Flour was substituted with whole wheat flour containing germinated brown rice powder. The sensory optimal composite recipe was determined by making cookies containing two levels of beet powder (A) or butter (B) according to Central Composite Design (CCD) and by conducting the sensory evaluation and instrumental analysis according to Response Surface Methodology (RSM). Using CCD, the results of physical measurement for ten conditions with two variables were obtained. The values of lightness (L), redness (a), and yellowness (b) were in the range of 36.65~49.03, 22.15~29.31, and 13.96~19.34, respectively. Lightness decreased significantly (P<0.001) and redness increased significantly (P<0.01) upon an increase in beet powder. The results of sensory evaluation showed very significant values in color (P<0.05), texture (P<0.05), flavor (P<0.01), taste (P<0.05), and overall quality (P<0.05), whereas those of the instrumental analysis showed significant values in lightness (P<0.001), redness (P<0.01), spread ratio (P<0.01), and hardness (P<0.05). As a result, the optimal sensory ratio of beet cookie was calculated for beet powder 7.75 g and butter 77.88 g.

This study examines the quality characteristics of the muffins made by adding 3%, 6%, and 9% of beet powder, comparing with the reference group. The result showed that there has been no significant difference in the ash content from the groups added with 3% and 9% of beet powder. The height of muffins appeared to be 4.7~5.0 cm, which didn't show any significant difference among the samples. The volume of beet muffins has shown significant difference among the samples (p<0.001). From the measurement result by scanning electron microscope (SEM), the samples had thick cellular walls and coarse pores because there was less gluten content with increased beet powder. From the chromaticity measurement result, L value and b-value decreased, while a-value increased with increased beet powder. From the texture measurement result, hardness increased with increased beet powder. Adhesiveness appeared to be getting lower with increased beet powder. Also, there was significant difference among the samples for cohesiveness (p<0.001). Gumminess got higher in the samples added with 3% and 6% of beet powder, and the highest chewiness was shown in the sample group added with 3% of beet powder. From the sensory evaluation result, overall acceptance has appeared in order of 6% > 9% > 3% > 0%.

This study was conducted to evaluate the substitution effect of red beet powder on sodium nitrite in emulsion-type pork sausages, and to investigate the effect of the addition of red beet powder on the physicochemical characteristics of emulsion-type pork sausages at 10℃ for 6 weeks. The treatments were divided into five groups: Control (sodium nitrite 0.01%), T1 (sodium nitrite 0.005% + red beet powder 0.5%), T2 (sodium nitrite 0.005% + red beet powder 0.25%), T3 (red beet powder 0.5%), and T4 (red beet powder 0.25%). In the CIE^*I didn’t delete this asterisk (*) because it might be a marker for something you wish to add later, but please note that if there is no significance for the asterisk, it should be removed as a typographical error. color of emulsion-type pork sausages, the lightness value of the control was significantly higher than for the other groups (p＜0.05). The redness value was higher in T1, whereas the yellowness value was higher in the T3 and T4 groups compared with the others (p＜0.05). The pH values of emulsion-type pork sausages were significantly decreased in the T3 and T4 groups by the addition of red beet powder (p＜0.05). However, the DPPH radical-scavenging activity was higher in the T1 and T3 groups than in the others (p＜0.05). The residual nitrite ion was the highest in the control group (p＜0.05). Therefore, it is determined that red beet powder can substitute for nitrite as a natural colorant, and it has a slightly antioxidant effect in emulsion-type pork sausages.
