The purpose of this research was to prepare Yackwa by addition of red ginseng marc powder to enhance its functional properties. For this purpose, ginsenosides composition of red ginseng marc powder was analyzed and red ginseng marc powder was added at different levels (1 to 15%) for Yackwa preparation. Also, their quality characteristics such as texture and color were measured and sensory evaluation was performed. Four ginsenosides including Rg3, Rc, Rb2, and Rd were the most abundant forms in red ginseng marc powder. With the increase of red ginseng marc powder, the properties of hardness, cohesiveness, and gumminess of samples decreased. The $a^*$ value of sample was highest when 10% of red ginseng marc powder was added. With the addition of red ginseng marc powder, the $L^*$-and $b^*$-values of samples decreased significantly (p<0.05). Based on the results of sensory evaluation, we recommended 10% addition to prepare Yackwa with red ginseng marc powder.

Red ginseng has been considered a functional food, and many studies on red ginseng and the prevention of cancer, hypertension, arteriosclerosis and constipation have been conducted. In this study, white bread dough with 1, 2, 3, 4 or 5% red ginseng marc powder was measured by a farinograph, extensograph, amylograph, as well as for pH to evaluate the development time, stability, extensibility, resistance to extension, gelatinization temperature, and maximum viscosity temperature. The ash content of the wheat flour increased with an increasing content of red ginseng marc powder. The gelatinization maximum and the temperature for the gelatinization maximum of the flour-water suspension in the amylograph were not affected by the addition of red ginseng marc powder. The moisture absorption of the wheat flour in the farinograph increased as the content of red ginseng marc powder increased. Also, as the content of red ginseng marc powder increased, dough development time decreased. The extensibility of the dough in the extensograph showed a negative relationship with the amount of red ginseng marc powder added.

This study evaluated the quality characteristics of muffins added with different amounts (0%, 3%, 6%, or 9%) of red ginseng marc powder. The specific gravity of red ginseng marc muffin batter significantly increased with increasing amounts of red ginseng marc powder (P<0.05). Weight and baking loss rate of muffin were not significantly different from those of the control. Volume, height, and pH of muffins significantly decreased when amounts of red ginseng marc powder increased (P<0.05). The moisture contents of muffins added with red ginseng marc powder increased with increasing amounts of red ginseng marc powder. The lightness and yellowness of muffins and dough increased as concentration of red ginseng marc powder increased. Redness decreased as concentration of red ginseng marc powder increased. DPPH radical scavenging activity of muffins increased with an increase in the concentration of red ginseng marc powder. The hardness, gumminess, and chewiness decreased with increasing red ginseng marc powder concentration. Adhesiveness, springiness, cohesiveness, and resilience increased with addition of powder. Sensory test revealed no significant differences in color, texture, and mouthfeel between the muffin samples. Therefore, red ginseng marc powder can be incorporated into muffins up to 6% to improve functional quality of red ginseng marc and minimize changes in quality. Futhermore, this study proposes the possibility of development of various products using red ginseng marc.

In this study, sponge cakes were prepared with 3, 6, 9, 12, and 15% red ginseng marc powder. The samples and a control were then compared in terms of quality characteristics, including batter viscosity and specific gravity, moisture content, water activity, volume index, weight, color, textural characteristics, and sensory qualities, in order to determine the optimal ratio of red ginseng marc powder in the formulation. The batter samples containing 0, 12, and 15% red ginseng marc powder had significantly higher viscosity than the other samples. Specific gravity of batter was not significantly different among the batter samples. The control group presented significantly higher moisture content as compared to the samples containing red ginseng marc powder samples. Water activity, volume index, and weight of all samples were not significantly different among the samples. In terms of crust color, lightness, redness, and yellowness of the crust samples decreased as the level of red ginseng marc powder content increased. For the crumb color, lightness and yellowness decreased, and redness increased, with increasing red ginseng marc powder content. Hardness, cohesiveness, gumminess, and springiness were not significantly different among the samples; however, the red ginseng marc powder samples had significantly higher chewiness than the control group. In the sensory evaluation, as the content of red ginseng marc powder increased, scores for color, flavor, softness, overall acceptability, moistness, and egg-flavor decreased, while scores for red ginseng taste, bitterness, astringency, and off-flavor incresed. Overall, the 3 and 6% red ginseng marc powder samples obtained fairly good sensory scores. In conclusion, the results indicate that adding $3{\sim}6%$ red ginseng marc powder to sponge cake is optimal, providing good physiological properties as well as reasonably high overall consumer acceptability.

This study was carried out to investigate the optimum conditions for extraction of soluble acidic polysaccharides from ginseng marc. Method of carbazole-sulfuric acid was applied to determine the amount of acidic polysaccharides in ginseng marc. The amounts of soluble acidic polysaccharides in water extract of ginseng marc were increased with increasing extraction temperature. The contents of acidic polysaccharides were not significantly different despite the extraction time increasing from 0.5 hours to 6 hours. To estimate the rehydration rate of the freeze dried polysaccharide, the extracted acidic polysaccharide fraction powder was determined the amount of soluble acidic polysaccharides by carbazole-sulfuric acid method again. The rehydration rate of acidic polysaccharides from water-extract of red ginseng marc at room temperature was 100%. On the other hand, the rehydration rate of acidic polysaccharide of red ginseng marc at boiling temperature was about 50%. The rehydration rate of acidic polysaccharides from water-extract of white ginseng marc at room temperature was 50%. The rehydration rate of acidic polysaccharide of red ginseng marc at boiling temperature was about 40%. The rate of soluble acidic polysaccharide of Red Ginseng is higher than that of White Ginseng. We can find out the maximum extraction method of soluble acidic polysaccharide from ginseng marc.

This study investigated the physicochemical properties of Pekin duck breast meat obtained from ducks fed diets consisting different types of sipjeondaebo-tang by-products and red ginseng marc with fermented red koji during storage. A total of 180 Pekin ducks (0-day old) were divided into four groups, each consisting of three replicates (15 ducks per pen). This study investigated diets with four types of treatments: control (basal diet),1% blend powder, pelleted 1% blend, and coated pellets of 1% blend; the blend was a mixture of sipjeondaebo-tang by-products powder and red ginseng marc with fermented red koji. There was no significant difference (p>0.05) in duck breast meat pH on storage days 3 and 7, TBARS on storage days 0 through 7, and DPPH radical scavenging on storage days 0 and 7. However, the pH values on storage day 0 and DPPH radical scavenging on storage day 3 were significantly different (p<0.05) in the meats from control and treated diet fed ducks. Especially, on storage day 7, the breast meat from ducks treated with different types of sipjeondaebo-tang by-products and red ginseng marc with fermented red koji showed lower TBARS values and increased DPPH radical scavenging activity compared to the control. In conclusion, addition of different types of sipjeondaebo-tang by-product and red ginseng marc with fermented red koji to 1% blend might be helpful in increasing antioxidant effects and reducing product wastage.
