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.

In this study red ginseng was extracted with ethanol and then fermented by yeasts including Lactobacillus casei and Bifidobacterium longum. Fermented red ginseng extracts(FRGE) were found to be more effective antioxidants in vitro with regards to 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical scavenging activity than red ginseng extracts(RGE). In FRGE, the contents of ginsenosides $Rb_1$, $-Rb_2$ and -Rc were much lower than in RGE, however, the contents of ginsenosides 20(S)$-Rg_3$, 20(R)$-Rg_3$ and compound K were higher than RGE. FRGE was added to Yanggaeng(0, 5, 10, 15, 20%), and physicochemical and sensory evaluations of the Yanggaeng were conducted. The L and b values of Yanggaeng with added FRGE were decreased by increasing the ratio of FRGE, while the a value was increased. Sensory evaluations for, taste, color, flavor, texture and overall acceptability of Yanggaeng with addition of FRGE (10%) were applicable for improving the Yanggaeng product.

Viscous fermented red ginseng extracts were dried and coated using a fluidized bed coater to increase convenience and consumer acceptance. The methods for making spherical granules of fermented red ginseng extracts with increasing convenience were established by using indigestible dextrin. Spherical granules of fermented red ginseng extracts with increasing convenience were made by mixing indigestible dextrin at 40% (40% IDD), 50% (50% IDD), and 60% (60% IDD) versus the soluble solid content of fermented red ginseng extracts. Spherical granules of fermented red ginseng extracts showed less angle of repose than powder of fermented red ginseng extracts. This means that spherical granules of fermented red ginseng extracts had good fluency with increased convenience. The more indigestible dextrin showed higher yields. Although 50% IDD showed less yield than 60% IDD, 50% IDD was the best mixing ratio for making spherical granules of fermented red ginseng extracts, as fermented red ginseng extracts is known as a healthy food. The optimized operation conditions of the fluidized bed coater for making 50% IDD were feeding rate 0.54 mL/min, atomization air pressure 2.15 bar, and product temperature $83.03^{\circ}C$.

Red ginseng (RG) and fermented red ginseng (FRG) are produced from ginseng (GS) via certain biological processes. The main difference between three ginsengs is the composition of ginsenosides known as major metabolites having several biological activities. The concentration of the metabolites has been known to be dependent on the methods which make RG and FRG In this study, we investigated the effects of WG, RG and FRG on the productions of inflammatory proteins (NF-${\kappa}B$, iNOS, COX-2) and cytokines (TNF-$\alpha$, INF-$\gamma$) in LPS-stimulated RAW 264.7 cells. The levels of NO production and iNOS expression were suppressed by the treatment of white ginseng (WG), RG and FRG in LPS-stimulated cells. Also, the production of TNF-$\alpha$ and INF-$\gamma$ was decreased in the cells by all of them. It was indicated that the inhibition of NF-${\kappa}B$ activation in LPS-stimulated cells treated with three kinds of ginsengs was resulted from the suppression of the level of COX-2 expression and the phosphorylation of IkB by LPS. The present study indicated that RC showed the best biological activity among them and FRG was better than WG. The better activity of RG on the inhibition of NO production is considered to be caused by the difference of ginsenoside composition produced during their preparations. In order to elucidate the mechanism, animal test should be performed with three ginsengs.

Red ginseng(RG, steamed and dried root of Panax ginseng C. A. Meyer, family Araliaceae) and fermented red ginseng(FRG, fermented red ginseng by yeast and lactic acid bacteria) are known to show different pharmacological effects by changed composition of saponins through fermentation. We examined the effects of RG and FRG on $\beta$-hexosaminidase secretion, ICAM-1 expression, the mitogen-induced proliferation of lymphocyte from mice in ex vivo systems and HaCaT cell(keratinocyte) proliferation to compare the anti-allergic and anti-inflammatory effects between both groups. RG groups showed inhibition of $\beta$-hexosaminidase secretion and ICAM-1 expression at $1{\mu}g/ml$, $10{\mu}g/ml$ and the same effects were observed at all concentrations in FRG groups. In our study, RG increased LPS-induced B cell proliferation at $1{\mu}g/ml$ and ConA-induced B cell proliferation at $100\;{\mu}g/ml$ but FRG decreased LPS- and ConA-induced lymphocytes at $100\;{\mu}g/ml$. We showed that FRG increased the proliferation of HaCaT at 1, $10{\mu}g/ml$ but not by RG. These findings suggest that RG and FRG might have anti-inflammatory and anti-allergic effects, which can be needed to proper clinical concentration to applied to various allergic diseases and inflammation.

This study focused on alcohol fermentation properties of red ginseng extracts using Saccharomyces cerevisiae JF-Y3. Central composite design was employed to investigate the influence of red ginseng extract content ($10{\sim}50%$, v/v) and yeast extract ($0.5{\sim}2.5%$, w/v) on the properties of alcohol fermentation added with red ginseng extracts. Yeast cell growth was affected both by red ginseng extract content and yeast extract content, and red ginseng extract content had a greater effect on yeast cell number than yeast extract content. Yeast cell number increased along with decrease of the red ginseng extract content and with increase of yeast extract content. Alcohol content was maximal at 30% red ginseng extracts and 0.50% yeast extract and the predicted maximum value of alcohol content was 12.45%. Brix degree and total sugar content were significant within 1% level (p<0.01), and brix degree was affected both by red ginseng extract and yeast extract content. Total sugar content was significantly affected by red ginseng content.

Monascus-fermented Korean red ginseng (MFRG), fermented by Monascus purpureus KCCM 12002, may be an ideal candidate for the hepatoprotectic, hypolipidemic and antioxidative activities. Effect of MFRG powder on these parameters in rats was investigated. Body weight gain, food intake, and water consumption were not significantly different among the groups. Total and relative weights of liver were significantly higher in MFRG group than that in other groups. The activities of AST and $\gamma$-GTP were highly lowered in MFRG group compared to control group. Contents of serum total lipid and triglyceride were significantly lowered in silymarin group and were significantly increased in MFRG group compared to control group, but tended to be lowered in RG group. Serum content of total cholesterol tended to be lowered in silymarin, RG, and MFRG groups compared to control group. HDL-cholesterol contents was only significantly increased in MFRG group compared to control group. At the same time, atherogenic index (AI) was also significantly lowered in silymarin, RG and MFRG groups compared to control group, and this effect was more pronounced in MFRG group. Content of thiobarbituric acid reactive substances (TBARS) in the liver was significantly lowered in MFRG group and tended to lowered in silymarin and RG groups compared to control group. The hepatic glutathione concentration was significantly higher in silymarin and MFRG groups. Hepatic morphology in all experimental groups revealed clear-cut hepatic lobules with the uniform pattern of the polyhedral hepatocytes radiating towards the periphery from the central vein. These results suggested that MFRG may have anti-atherogenic index (AI) and antioxidative activity in normal dietary feeding rats.

Onion juices supplemented with different concentrations of puffed red ginseng extract were fermented using Pediococcus pentosaceus KC-007 and their biologically functional properties were investigated. When onion juices were supplemented with puffed red ginseng extract at the concentration of 0.5, 1, 2, and 4% (v/v) each, viable cell number of lactic acid bacteria was the highest at 24 hr of fermentation in all samples. The titratable acidity increased as the fermentation proceeds irrespective of the added amount of red ginseng extract, and the pH of fermentation broth decreased until 36 hr of fermentation. The reducing sugar of fermentation broth decreased until 24 hr of fermentation and did not change thereafter. The electron donating ability and nitrite scavenging ability were highest when red ginseng extract was added at the concentration of more than 1% (w/v). The overall acceptance in sensory evaluation was the best when red ginseng extract was added at the concentration of 1% (w/v). From these results, it is confirmed that the optimum concentration of puffed red ginseng extract for the lactic acid fermentation of onion juice was 1% (w/v).

Comparison of the physico-chemical characteristics were investigated among white (WG), fermented (FG) and red ginseng (RG) extracts. We observed maximum contents of extractable solids in FG, but viscosity was lower than other ginseng extracts. The contents of ash and crude protein of FG were higher than those of other ginseng extracts. The contents of carbohydrate were similar, but component Na and cruid lipids were maximum in RG. we extended our study on comparison of the calories among WG, FG and RG. We noticed that comparison of the calories among WG, FG and RG showed insignificant difference.
