This study was conducted to evaluate the effects of red ginseng marc powder on egg freshness in laying hens during 4 weeks. A total of 60 Hy-line Brown laying hens, 50 week of age, were randomly assigned to 2 groups with diets containing 0% and 2% red ginseng marc powder. There were 3 replications per group with 10 laying hens per pen. Throughout the period of the trial, there were no effects of red ginseng marc powder on egg weight (but not 4 weeks). Haugh Unit (HU) values were observed by showing significant differences between red ginseng marc powder and controls at 0 and 4 weeks, except for HU at 1 through 3 weeks. For egg yolk color, red ginseng marc powder has no difference in comparison with controls at 0, 3 and 4 weeks (but not 1 and 2 weeks). In conclusion, the dietary supplementation with 2% red ginseng marc powder improved HU values throughout the experiment.

Background: The aim of this study was to evaluate the effects of Korean Red Ginseng marc with aluminum sulfate as litter amendments on ammonia, soluble reactive phosphorus, and pathogen populations in poultry litters. Methods: Increasing levels of Korean Red Ginseng marc with aluminum sulfate were applied onto the surface of rice hull as a top-dress application; untreated rice hulls served as controls. Results: Treatment with Korean Red Ginseng marc with aluminum sulfate or aluminum sulfate alone resulted in lower litter pH (p < 0.05), as compared with that of the controls. There were some differences (p < 0.05) between treatments with Korean Red Ginseng marc with aluminum sulfate or aluminum sulfate alone and controls at 2-4 wk (not at 1 wk). Ammonia levels reduced on an average by 29%, 30%, and 32% for 10 g, 20 g Korean Red Ginseng marc with aluminum sulfate, and aluminum sulfate alone, respectively, as compared with controls at 4 wk. During the experiment, Korean Red Ginseng marc with aluminum sulfate or aluminum sulfate treatment had an effect (p < 0.05) on soluble reactive phosphorus content, as compared with the controls (not at 4 wk). A decrease in Salmonella enterica and Escherichia coli was observed (p < 0.05) in litter amended with both Korean Red Ginseng marc with aluminum sulfate and aluminum sulfate alone, as compared with the control, except at 1-3 wk for Salmonella enterica and 1 wk and 4 wk for Escherichia coli, respectively. Conclusion: The results showed that using Korean Red Ginseng marc with aluminum sulfate (blends), which act as acidifying agents by reducing the pH of the litter, was equally effective as aluminum sulfate in reducing the environmental impact.

This study was carried out to investigate the optimum conditions for extraction of acidic polysaccharide from red ginseng marc produced by manufacturing alcoholic and water extract from red ginseng. Extraction efficacy of acidic polysaccharide from dried red ginseng marc was higher than that before drying. The appropriate conditions for the extraction of acidic polysaccharide from red ginseng marc were particle size under 3.35 mm after drying red ginseng marc, 1∼2 hours of extraction time and 2∼3 extraction times, respectively. The amount of acidic polysaccharide in water extract from red ginseng marc treated with $\alpha$-amylase and cellulase increased about 20∼50%. From the above resuts, we suggest that red ginseng marc produced by manufacturing alcoholic and water extract of red ginseng has higher potencies in the utilization of waste materials.

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 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.

We conducted two experiments to evaluate effects of feeding various types of red ginseng marc and Houttuynia cordata (H.cordata) on blood profiles of poultry in a completely randomized design. In experiment 1 (28 d), a total of 240 broilers (Arbor acres) were used. Four dietary treatments (15 broilers per pen with four replicate pens per treatment) were included: (1) control, (2) 2% red ginseng marc, (3) 1% fermented red ginseng marc with red koji, and (4) 2% liquid red ginseng. There were no significant differences in HDL and LDL-cholestrol among treatments (P > 0.05), but total cholesterol and triglyceride decreased in diets supplemented with red ginseng marc and 1% fermented red ginseng marc with red koji compared to that in the control treatment (P < 0.05). In experiment 2 (38 d), a total of 240 Pekin ducks were randomly divided into 4 groups by dietary treatments (control, 1% fermented H. cordata powder with red koji, 1% fermented H. cordata pelleted with red koji, and 1% fermented H. cordata coated with red koji) with 4 replicates of 15 ducks in each group. Total cholesterol and VLDL-cholesterol were not affected by diet with various types of H. cordata. However, increase in HDL-cholesterol and decrease in LDL and VLDL-cholesterol were greater in treatments with different types of H. cordata than in the control treatments (P < 0.05). In conclusion, using various types of red ginseng marc and H. cordata in poultry diets was effective for increasing HDL-cholesterol and decreasing total, LDL, and VLDL-cholestrol or triglyceride.

Red ginseng has been considered as a functional food, with much researches on the prevention of cancer, hypertension, arteriosclerosis and constipation having been conducted. In this study, white bread, with the addition of 1, 2, 3, 4 or 5% red ginseng marc powder was measured for its moisture content, volume, height, color, and texture, and sensory analysis was also conducted. The moisture content increased with increasing red ginseng marc powder content. The volume and height of the bread were decreased with increasing red ginseng marc powder content. The crust color, lightness, yellowness and redness all decreased with increasing red ginseng marc powder content. Both the crumb color, and lightness decreased, but the yellowness and redness increased writh increasing red ginseng marc powder content. In the consumer acceptability test, the white bread with a 2% red ginseng marc powder content was shown to have the most favorable quality characteristics.

The red ginseng marc was roasted at various conditions and its organo-leptic properties and flavor components were investigated. Scorched-rice odor and roasted odor and the roasted red ginseng marc powder were much stronger than those from the unroasted red ginseng marc powder while earth odor, old-rice odor, metalic off-odor and woody odor were much weaker than those from the unroasted red ginseng marc. Savory odor and scorched-rice odor as well as savory taste and astringent taste from the water-extract of red ginseng marc roasted at $200^{\circ}C$ were stronger, but smoky odor, woody odor, biner taste and rough taste were weaker than those roasted at $230^{\circ}C$. Seven kinds of pyrazines, two kinds of carbonyl compounds, seven kinds of acids, two kinds of esters, five kinds of phenolic compowlds, maltol and six other compounds were identified as flavor components in distillate from red ginseng marc roasted at $200^{\circ}C$ for twenty minuties. Of them pyrazines and maltol are thought to be compounds which have characteristic odor such as roasted odor and/or scorchedrice odor in the roasted red ginseng marc.

This study was conducted to determine the effects of mixed Korean red ginseng marc with aluminum sulfate on gas concentration and volatile fatty acid (VFA) in poultry litter during 4 weeks in terms of livestock and environment managements. A total of 240 broiler chicks were randomly allocated to four treatments in four replications and 15 birds per replicate. The four treatments was mixed to rice hull under each pen at 0, 10 g or 20 g red ginseng marc + 90g aluminum sulfate, and 100g aluminum sulfate per kg poultry litter (rice hulls). Carbon dioxide, methane, acetic acid, and propionic acids were measured weekly. The results that could be available include: First, during the experimental period, carbon dioxide emissions were not remarkably different among treatments. Second, no differences were observed among treatments in methane emissions at 2 weeks through 4 weeks, but at 1 week, the reduction in methane emissions was in following order: 100 g aluminum sulfate > 20 g red ginseng marc + 90 g aluminum sulfate > 10 g red ginseng marc + 90 g aluminum sulfate > control. Third, in spite of statistically differences, treatment with 10 g or 20 g red ginseng marc + 90g aluminum sulfate, and 100g aluminum sulfate reduced acetic acid and propionic acid as a function of time, except acetic acid in aluminum sulfate treatment at 2 and 4 weeks. In conclusion, the results indicated that like aluminum sulfate, using 10 g or 20 g red ginseng marc with aluminum sulfate was effective in decreasing methane and propionic acid released from poultry litter.

The purpose of this research was to investigate the effects of nondigestible oligosaccharides (NDO) from red ginseng marc on the growth of Bifidobacterium spp. Red ginseng marc, a fibrous byproduct of ginseng extract from processing, was destarched by ${\alpha}$-amylase and amyloglucosidase treatment, and then treated with a commercial pectinase to produce NDO. The bifidogenic effects of NDO on B. adolescentis, B. animalis, B. breve, and B. longum were investigated in vitro. NDO significantly promoted the growth of Bifidobacterium spp. The growth, decrease of pH, and organic acid formation (acetate, lactate, formate) were markedly different among the species. B. adolescentis showed the best growth and produced the greatest amount of organic acids. When NDO was used as a carbon source in the cocultivation of Bifidobacterium spp. and Clostridium perfringens, the growth of Bifidobacterium spp. was not influenced by the existence of Cl. perfringens. The result strongly suggested that NDO from red ginseng marc could be used as a potential bifidogenic source.
