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.

In this study, we investigated the appropriate conditions to extract acidic polysaccharide and to prepare red ginseng extract being rich in acidic polysaccharide from red tail ginseng marc produced after manufacturing alcoholic extract from red tail ginseng. Amount of acidic polysaccharide in red tail ginseng marc was about 11%. The best condition for the extraction of acidic polysaccharide from the marc was using of 3~5 mg of $\alpha$-amylase/g residue/15 ml of distilled water, and the amount of acidic polysaccharide in water extract of the residue treated with $\alpha$-amylase was about 27%. So, it is possible to manufacture red ginseng extract being rich in acidic polysaccharide using water extract of red tail ginseng alcoholic residue as extraction solvent. From the above results, we suggest that red tail ginseng residue produced by manufacturing alcoholic extract of red tail ginseng has high potencies in the utilization of waste material.

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.

This study was carried out to investigate the optimum conditions for extraction of acidic polysaccharides from red ginseng marc produced by manufacturing alcoholic extract from red ginseng. Method of carbazole-sulfuric acid was applied to determine the amount of acidic polysaccharides in red ginseng marc. The amounts of acidic polysaccharides in water extract of red ginseng marc were increased with increasing extraction temperature. The contents of acidic polysaccharides were not significantly different despite of the extraction time increasing from 6 hours to 48 hours. The contents of starch in water-extract of red ginseng marc were increased with increasing extraction temperature. The starch amounts in water extract of red ginseng marc extracted for 48 hours were increased. The yields of polysaccharide precipitated from water-extract of red ginseng marc were increased with increasing extraction temperature. The hydration rate of acidic polysaccharides and starch from water-extract of red ginseng marc were decreased with increasing extraction temperature. The contents of starch were not significantly different despite of the extraction time increasing from 6 hours to 48 hours at $8^{\circ}C$. However, the rehydration rate of acidic polysaccharide for 48 hours were decreased at $8^{\circ}C$. The rehydration rate of acidic polysaccharide and starch extracted from 6 hours to 24 hours at $25^{\circ}C$ were not significantly different, but those extracted for 48 hours were increased. From the above results, we suggest that by altering the extraction conditions in red ginseng marc it is possible to develop optimum conditions for extraction that modulate the proportions of acidic polysaccharide and starch.

This study was conducted to investigate the effects of dietary supplementation of various types of fermented red ginseng marc with red koji to laying hens on eggshell and egg yolk quality characteristics. A total of 240 Hy-line Brown laying hens (40 wk of age) were randomly allotted to 24 pens (6 replicates per treatment and 10 laying hens per replicate). Experimental diets consisted of 4 treatments containing basal diet (control), 1% fermented red ginseng marc powder with red koji, 1% fermented red ginseng marc pelleted with red koji and 1% fermented red ginseng marc coated with red koji. During the 8-wk feeding trial, there were no significant differences in eggshell strength, eggshell thickness and eggshell color among the treatments, except for eggshell strength at 4 and 8 wk and eggshell thickness at 0 wk. In addition, no differences in egg yolk color and egg yolk index were found for all treatments throughout the 8-wk feeding period, except for egg yolk color at 0 wk. Thus, using various types of fermented red ginseng marc with red koji to laying hens did not improve eggshell and egg yolk quality characteristics.
