The purpose of this study is to determine the possibility of using cultured wild ginseng roots as a natural health food source. To accomplish this purpose, the contents of general and antioxidative nutrients of cultured wild ginseng roots were measured. The contents of carbohydrate, crude protein, crude lipid and ash are 61.72%, 17.36%, 0.23% and 10.90%, respectively. Further, the calories of cultured wild ginseng roots were 323.97 kcal. Total dietary fiber was 82.13%. The protein contained a total of 18 different kinds of amino acids. The contents of amino acids were 16.15 g. The K was the largest mineral followed by P, Ca, and Mg, which means cultured wild ginseng roots is alkali material. The contents of saturated fatty acids and unsaturated fatty acids were 0.23 g, and 0.62 g, respectively. Crude saponine content was 25.87 mg/g. Total phenolic contents of cultured wild ginseng roots were 11.2mg/g, and total flavonoids contents were estimated as 4.2mg/g. The electron donating ability of cultured wild ginseng roots were 24.7~31.6%. The nitrite scavenging activity was pH dependent, and was highest at pH 1.2 and lowest at pH 6.0. The cultured wild ginseng roots extract showed the highest reducing power (0.06) at the concentration of $1,000{\mu}g/m{\ell}$. Based on the above results, we deemed that the cultured wild ginseng roots might have potential antioxdant activities.

Drying of raw ginseng root down to 35% moisture content required for extrusion process. There were two kinds of pre-treatments of raw ginseng root which were chopping and whole-root ginseng before frying at 80, 100 and 12$0^{\circ}C$. Drying rate and physicochemical properties of dried ginseng were evaluated to determine optimum drying temperature for extrusion process. Drying time at 8$0^{\circ}C$ to decrease to 35% moisture was 6.5 hr and ginsenoside content in dried ginseng at 8$0^{\circ}C$ was lower than that of dried ginseng at 100 and 12$0^{\circ}C$. Drying time at 100 and 12$0^{\circ}C$ to decrease to 35% moisture was 5.5 and 3.5 hr and redness of dried ginseng powder was 5.20 and 7.23 respectively. Browness and redness of dried ginseng extract from 75% ethylene were significantly increased with the increase in drying temperature. Ginsenosides Rb1, Rb2, Rc, Rd, Rg1 and total saponin were also increased with the increase in drying temperature from 8$0^{\circ}C$ to 10$0^{\circ}C$, however, those were not significantly different with drying temperature at 100 and 12$0^{\circ}C$. Drying temperature for extrusion process can be optimal at 10$0^{\circ}C$.

For prevention of moisture adsorption, the fermented red ginseng extract spherical granules were coated by using hydrophobic fractions. The hydrophobic parts were extracted from red ginseng such as the perfect soluble part in 90% ethanol (PSE) and non-soluble part in hot water (NSHW). The optimum operating conditions for making fermented red ginseng extract spherical granules coated with PSE were a feeding rate (FR) of 0.49 mL/min, atomization air pressure (AP) of 2.14 bar, and product temperature (PT) of $48.96^{\circ}C$., whereas conditions for granules coated with NSHW were a FR of 0.61 mL/min, AP of 2.75 bar, and PT of $46.30^{\circ}C$. The solubility of coated fermented red ginseng extract spherical granule was lower than that of not coated. The fermented red ginseng extract spherical granules coated with NSHW showed more preventative effects for moisture adsorption than those coated with PSE, although there were no differences in solubility and fluidity. In the sensory evaluation, granules coated with hydrophobic fractions extracted from red ginseng were shown to be bitterer and less soluble than those not coated spherical granules. In conclusion, fermented red ginseng extract spherical granules coated with hydrophobic extracts from red ginseng showed a preventative effect against moisture.

This study was performed to investigate the antioxidant activity of Korean ginseng using an ORAC(Oxygen Radical Absorbance Capacity) assay. Four fractions each (80% ethanol, ethyl acetate, water saturated 1-butanol, and water) were obtained from different ginseng samples (White Ginseng: ; 6 yrs-., 5 yrs-., ; Cork Ginseng: ; 5 yrs-., 4 yrs-.). The saponin content of each fraction was quantified by LC/MS, and the antioxidant capacity of the ginseng was measured by the ORAC assay. The ORAC method, which was recently validated using automatic liquid handling systems, has been adapted for manual handling with the use of a conventional fluorescence microplate reader. Furthermore, the ORAC assay provides a direct measure of hydrophilic chain-breaking antioxidant capacity against peroxy radical, which is the exiting and emission of 2,2'-Azobis (2-methylpropionamidine)-dihychloride (AAPH). As a result of our experiments, ginsenosides Rg1 and Rb1 were the two major saponins found in the ginseng samples, and Rc, Rb2, Re, Rd, Rg3, and Rh1 were detected in a small quantities. For the antioxidant capacities of the fractions (80% ethanol, ethyl acetate, butanol, and water), we found that the organic solvent fraction had similar antioxidant capacities, and were higher than the capacity of the water fraction. When determining the similarities in each fraction, only the ethyl acetate fraction showed similarity compared to other fractions (p>0.05). The antioxidant capacity of ginseng may come from phenolic compounds and some nonpolar saponins. However, based on the results of this study, we hypothesize that some acidic polysaccharides and other biological components may contribute to its antioxidant capacity. Additional research is required to determine other possible biological response modifiers that contribute to the antioxidant capacity of ginseng.

Panax ginseng has been used since ancient times based on the traditional Asian medicine theory and clinical experiences, and currently, is one of the most popular herbs in the world. To date, most of the studies concerning P. ginseng have focused on specific mechanisms of action of individual constituents. However, in spite of many studies on the molecular mechanisms of P. ginseng, it still remains unclear how multiple active ingredients of P. ginseng interact with multiple targets simultaneously, giving the multidimensional effects on various conditions and diseases. In order to decipher the systems-level mechanism of multiple ingredients of P. ginseng, a novel approach is needed beyond conventional reductive analysis. We aim to review the systems-level mechanism of P. ginseng by adopting novel analytical framework-network pharmacology. Here, we constructed a compound-target network of P. ginseng using experimentally validated and machine learning-based prediction results. The targets of the network were analyzed in terms of related biological process, pathways, and diseases. The majority of targets were found to be related with primary metabolic process, signal transduction, nitrogen compound metabolic process, blood circulation, immune system process, cell-cell signaling, biosynthetic process, and neurological system process. In pathway enrichment analysis of targets, mainly the terms related with neural activity showed significant enrichment and formed a cluster. Finally, relative degrees analysis for the target-disease association of P. ginseng revealed several categories of related diseases, including respiratory, psychiatric, and cardiovascular diseases.

In order to observe the effect of defatted ginseng which is made by extracting fat from ginseng using petroleum ether during the growth and the starvation, the powder of defatted ginseng was added to the basal diet by 25% and 50% respectively, and the mixtures were fed for 4 weeks to just weanling white female rat which weighed 78-82 g. As for the diet initake, there was not showed any meaningful difference between the defatted ginseng powder fed group and the control group (to which was fed just - the basal diet not including defatted ginseng powder), but the protein intake for the former group appeared to be reduced (P<0.02-0.01) compared to the control group. As for the growth rate, that of the defatted ginseng powder fed group appeared higher (P<0.02) than that of the control group in 1 week after feeding, but since after 2 weeks, there was not showed meaningful difference between the two groups. As for the weight-reduction rate by starvation, that of the 25% defatted ginseng powder fed group showed just 79.6% (P<0.05) of the control group's in 5 days after feeding, but the rate of the 50% defatted ginseng powder fed group appeared 119.3% of the control group's. As for the required time from the beginning of starvation to the death, it was resulted that the higher the rate of defatted ginseng addition is, the shorter the time becomes (P<0.05)

The objectives of this study were to investigate the quality characteristic of the nutrition bar with various concentrations (0, 5, 10, 20%) of defatted ginseng seed meal(DGSM). Specific gravity and pH of bar batters were lower in bars containing DGSM. Specific volume, loss rate and leavening rate of bars were decreased as DGSM increased. In color of bar crust and crumb, the L and bcolor values decreased according to the level of DGSM added, whereas the a color valuesand ${\triangle}$ increased. The bars with 5, 10 and 20% DGSM had significantly higher hardness value than control bar (p < 0.05). The result of sensory evaluation showed that intensity scores for color, flavor, taste, after taste and texture were highest for the nutrition bar substituted with 20% DGSM. The nutrition bar with 10% DGSM attained the highest overall acceptability score. Results indicated that optimal concentration of DGSM into the nutrition bar was 10%.

We focused on the condition of washed, fresh ginseng in the market and analyzed consumer attitudes to the product to improve the consumption of fresh ginseng. A preference for fresh ginseng was high among every age class, and was particularly notable in older individuals. Fresh ginseng was usually eaten as ginseng chicken soup, mostly in summer and winter, and as a valuable health food, rather than because of desirable qualities of taste or smell. A total of 66.5% of those surveyed reported that they had purchased fresh ginseng, mostly from big discount stores. Such stores were preferred as outlets owing to a reputation for quality and shopper convenience (the stores were located near interviewees' homes). More than 70% of purchasers emphasized that they chose to purchase in department stores and traditional markets owing to the reputation for quality of such sources. Most consumers considered quality to be a prime element in purchase decisions. A total of 32.9% of those surveyed had bought washed fresh ginseng to give as a gift to a friend. Of those surveyed, 67.1% had never bought washed fresh ginseng. The following reasons were proposed to explain the preference for purchase of ginseng with attached soil. Most consumers (40.2%) thought the soil was a reflection of quality. Those who preferred washed fresh ginseng considered that the material was hygienic and convenient to store. When questioned about their intention to buy washed fresh ginseng, 55.0% of consumers replied in the affirmative and 17.1% in the negative. When consumers were asked whether they would be willing to pay an additional charge for the washing and packing of fresh ginseng, 58.8% answered in the affirmative.

This study was performed to process Tofu as an hypolipidemic food using black ginseng. Before processing we performed the ameliorating effect of black ginseng on the serum levels of triglyceride and total cholesterol in diabetic mice (db/db mice). As a result, the diabetic mice, whose diet was supplemented with black ginseng has a reduced level of serum lipid total cholesterol ($124.58{\pm}10.59mg/dL$) compared to non-supplemented diabetic mice, The supplemented mice exhibited a significant decrease (p<0.05) in serum lipid triglycerides ($80.32{\pm}35.40mg/dL$), which provided the efficacy of black ginseng in reducing hyperlipemia, thus indirectly proving the prevention and treatment of obesity. Then we processed Tofu as a hypolipidemic food using 0~8% black ginseng extract. We evaluated the quality characteristic after producing black ginseng Tofu. For color value, as the addition level of color increases, the value of L (lightness) decreased and a (redness), b (yellowness) increased. With increase in black ginseng concentrate additional level increases, the hardness, gumminess, and chewiness values increased (p<0.05), but the springiness and cohesiveness showed no significant differences. In case of sensory evaluation, Tofu with the addition of 2% black ginseng concentrate (BGT2) showed the highest preference overall. To sum up, black ginseng demonstrated pharmacological effects in treating diabetic complications like hyperlipidemia and reducing body deposit fat.
