The principal objective of this study was to assess the sensory and mechanical characteristics, moisture content and color values of Ogapisulggi by varying the quantity of Acanthopanax sessiliflorus Seemann var. Goma(Ogapi) berry powder and the types of sugar utilized. The moisture content, color values, texture characteristics, and sensory characteristics of the different Ogapisulggi were then measured and compared. When the quantity of the Ogapi berry powder was the same, Ogapisulggi with honey added and the equal amount of sugar and honey added group was moister than that with sugar. The ightness values and yellowness values were decreased with increasing the Ogapi berry powder, whereas the redness values was increased. In particular, decreased proportions were observed in the Ogapi berry powder and sugar-added group($R^2$=0.922), the equal amount of sugar and honey-added group($R^2$=0.922) and the honey-added group$R^2$=0.966). In our texture analysis, hardness and adhesiveness values were reduced in the 0.3% Ogapi berry powder-added group, and springiness, cohesiveness, and chewiness values were increased the Ogapi berry powder-added group. Sensory evaluation showed that the Ogapisulggi containing 0.3% Ogapi berry powder was the lowest in terms of color, flavor, after-swallowing and overall preference. On the basis of the results of this study, the best ratio of ingredients was as follows: 0.3% addition of Ogapi berry powder with sugar and 0.1% addition of Ogapi berry powder with honey, which supports the conclusion regarding the benefits of Ogapi berry powder supplementation in Ogapisulggi in terms of taste and functionality.

The objective of this study was to evaluate physicochemical and sensory properties, the texture profile, and antioxidant activity of ginseng extract-supplemented quark cheese as a new cheese product intended to improve public health. After addition of less than 1.0% ginseng extract, the moisture content of quark significantly decreased, while fat and protein levels increased, although microbial counts and lactose and ash contents were not affected significantly (p<0.05). In terms of color, $L^*$ values decreased significantly with increasing concentration of ginseng extract, while $a^*$ values increased significantly (p<0.05). The results of texture profiling showed that cohesiveness and springiness were unaffected, whereas hardness, gumminess, and chewiness increased significantly. The 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical-scavenging activities of the cheese fortified with 0%, 0.5%, or 1.0% of the ginseng extract were $4.22%{\pm}0.12%$, $20.14%{\pm}1.34%$, and $56.32%{\pm}1.54%$, respectively. The results of sensory analysis indicated that bitterness, ginseng odor, and aftertaste significantly improved with increasing concentration of ginseng extract (p<0.05). However, there was no significant difference in the overall quality attributes of quark cheese between the no-supplement control and samples with less than 0.5% of the ginseng extract (p>0.05), suggesting that these products could help to promote public health as functional foods.

This study was carried out to examine the sensory characteristics of Demi-glace sauce prepared by fresh basil with different amount of salt added. The evaluation of the sensory quality of Demi-glace sauce prepared by fresh basil was conducted by unexperienced and trained panel with regard to color, odor, taste, appearance, texture, viscosity, and overall acceptability while varying the quantity of salt added, the time of preparation, and the conditions of sauce offered in which each panel was supposed to evaluate both sauce itself and sauce with meat. It was found that Demi-glace sauce prepared by fresh basil with 0.3% salt added was gained the highest score from both panels in most properties and the second was the one with 0.1% salt added. In the sensory properties correlation analysis according to the time of preparation and the conditions of sauce offered, there was no significant correlation in most sensory properties for the unexperienced panel, except some significantly positive correlation between taste and overall acceptability of the sauce. Whereas there was a positive correlation in the majority of sensory properties for the trained panel regardless of the time of preparation and the conditions of sauce offered. The sauce with 0.3% salt added ranked as the best recipe by both panels among four different ratios of salt adding regardless of the time of preparation and the conditions of sauce offered. Triangle test showed that the sauce B with 0.1% salt added before the preparation was more highly appreciated in terms of taste than the sauce A with 0.1% salt added in the final step of preparation. In conclusion, it could be suggested that Demi-glace sauce prepared by fresh basil with 0.3% salt added is the best recipe for commercial products. Also, there seems to be the need of further sensory evaluation studies on the Demi-glace sauce according to the time of addition during the process of preparation.

The objective of this study was to investigate the quality and sensory characteristics of yanggaeng prepared with different amounts of ginseng paste. Ginseng paste was incorporated with yanggaeng at a range of different levels of 5~15% based on the total weight of water. The pH and total acidity of yanggaeng were 6.35~6.49% and 0.03~0.07%, respectively. The sugar content of yanggaeng in the control was $25.0^{\circ}Brix$ and showed proportional increases up to $25.0{\sim}29.7^{\circ}Brix$ with increasing levels of ginseng paste. In terms of the texture profile analysis, the hardness and adhesiveness of yanggaeng decreased but the cohesiveness, gumminess, and chewiness increased compared to the control and ginseng paste added treatments. In color value determination, the $L^*$ and $a^*$ values decreased but the $b^*$ value increased with increasing levels of ginseng paste. The sensory evaluation indicated that the yanggaeng contained up to 15% ginseng paste and showed similar flavor, taste, texture, and overall acceptance in the control. These results suggest that ginseng paste is an ingredient that can enhance the quality and sensory potential of yanggaeng.

In this study, we assessed the physicochemical and sensory characteristics of cookies containing various concentrations (0, 3, 5, 7 and 9%) of leek powder. The L values of cookies containing leek powder were significantly lower than those of the controls. The spread ratio decreased proportionally with the quantity of leek powder added to the cookie recipe. The loss rate and leavening rate of samples to which 3% and 5% leek powder was added evidenced a higher value than the samples to which 7% and 9% leek powder was added. The L value of brightness was significantly reduced when leek powder was added to the cookie recipe. The a and b values were also significantly reduced with the addition of leek powder. Hardness evidenced significantly high levels in the samples to which 3% and 5% leek powder was added. The results of our sensory evaluation evidenced significantly better appearance, flavor, color, texture and overall acceptability as compared to the 3% and 5% added samples. The observed quality characteristics of the 3% leek powder added samples and 5% leek powder added samples indicated the possibility that leek cookies might be developed.

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.
