Recent trend of ginseng (p. ginseng) trade in Japan was analyzed. From 1984 white ginseng import increased continuously to 240% while export of red ginseng decreased to 29%. Red ginseng import increased until 1990 and decreased thereafter, resulting in 12% of total import ginseng in 1993 from 47% in 1990. During five years (1989∼1993) white ginseng import from Korea decreased from 44% to 14% of total white ginseng imported while import from China increased. Red ginseng import from China ranged 97 to l00% of total red ginseng and little change was shown during five years. Price of Korean ginseng was higher than that of China by 2.2 times for white and 6.6 times for red. The continuous decrease of Chinese ginseng price might affect import trend. Export price of red ginseng increased continuously and was higher than that of Korean red ginseng (1.95 times) and much higher than import price (20 times in 1993).

This mass balance study about ginsenoside Rg1 and Re in Red ginseng processed from Fresh ginseng is useful to understand that herbal material sources of ginseng and raw material consumption in Red ginseng preparations. In our results, total molar amounts of ginsenoside Rg1, Re and their converts in Fresh ginseng, Red ginseng, and Red ginseng extract are substantially the same. The molar amounts of ginsenoside Rg1, Re (4.324, 2.880 μmol/g) as starting materials in Fresh ginseng are kept constant as total molar amounts (sum of starting and converts) in Red ginseng (4.264, 2.596 μmol/g) and Red ginseng extract (3.389, 3.129 μmol/g). This result means that protopanaxtriol type ginsenosides and their characteristic converts are not destroyed or inflowing in Red ginseng process. Therefore, it is important for quality assurance of Red ginseng preparations that the ratio between ginsenosides Rg1, Re and these converts is kept constant.

This study was carried out to determine the differences of essential oil components among Korean, Chinese and Japanese red ginseng, and Korean white ginseng (Panax ginseng C.A Mayer) , American and Canadian ginseng (P. Quinquefolium), and sanchi ginseng (P notoginseng). The steam distilled oils of these ginsengs were analyzed by GC and GC-MS, and 22 sesquiterpenes, 8 sesquiterpene alcohols, 8 monoterpenes, 5 aldehydes, 4 esters, 3 acids, 2 alcohols and 5 miscellaneous components were identified. The major oil components of Korean, Chinese and Japanese red ginseng were $\beta$-panasinsene, $\beta$-caryophyllene, $\alpha$-panasinsene, $\alpha$-neoclovene, selina-4,11-diane, bicyclo-ger-macrene and spathulenol. The contents of $\beta$-panasinsene, $\alpha$-neoclovene, $\alpha$-basabolene and spathulenol were higher in Korean red ginseng than Chinese and Japanese red ginseng. The contents of $\alpha$-cubebene, selina-4,11-diene and ledol were higher in Chinese red ginseng than Korean and Japanese red ginseng, but those of selina-4,11-diene and spathulenol were lower in Japanese red ginseng than Korean or Chinese red ginseng. On the other hand, the GC patterns of the oils from American, Canadian and sanchi ginseng were different from that of Korean white ginseng.

To compare the effects of red Ginseng and white Ginseng on the growth of experimental animals, both Ginseng were given to Broiler male chicken. Red and white Ginseng were administered to Broiler chicken in doses of 0.25, 0.5, 1, 2 and 4g per kg weight of chicken. The increase in weight were 282g in red Ginseng group and 162g in white Ginseng group compared with control group. The increase of the feeding amounts per kg weight were 2.4kg for red Ginseng group, 2.67kg for white Ginseng group and 2.87kg for non-treated group. The growth of each organ in the red Ginseng group showed favorable increase trend than white Ginseng group as a whole and, particularly, considerable significance were observed in liver and brain. These results suggest that red Ginseng has better effect on the growth of chicken and organ than white Ginseng does.

Background: It has been known that ginseng can be applied as a potential nutraceutical for memory impairment; however, experiments with animals of old age are few. Methods: To determine the memory enhancing effect of red ginseng, C57BL/6 mice (21 mo old) were given experimental diet pellets containing 0.12% red ginseng extract (approximately 200 mg/kg/d) for 3 mo. Young and old mice (4 mo and 21 mo old, respectively) were used as the control group. The effect of red ginseng, which ameliorated memory impairment in aged mice, was quantified using Y-maze test, novel objective test, and Morris water maze. Red ginseng ameliorated age-related declines in learning and memory in older mice. In addition, red ginseng's effect on the induction of inducible nitric oxide synthase and proinflammatory cytokines was investigated in the hippocampus of aged mice. Results: Red ginseng treatment suppressed the production of age-processed inducible nitric oxide synthase, cyclooxygenase-2, tumor necrosis factor-${\alpha}$, and interleukin-$1{\beta}$ expressions. Moreover, it was observed that red ginseng had an antioxidative effect on aged mice. The suppressed glutathione level in aged mice was restored with red ginseng treatment. The antioxidative-related enzymes Nrf2 and HO-1 were increased with red ginseng treatment. Conclusion: The results revealed that when red ginseng is administered over long periods, age-related decline of learning and memory is ameliorated through anti-inflammatory activity.

Browning intensity is a major factor to estimate the quality of red ginseng or red ginseng products. The Maillard type of browning reaction proceeds nonenzymatically during extraction and concentration of red ginseng. The present studies were carried out to investigate the effects of amino acids and sugars on the browning reaction during extraction and concentration of red ginseng. Red ginseng was pulverized to 115 mesh and then tenfold (v/w) of water was added to the powder to make the substrate of red ginseng. Solution (0.1 M) of fourteen amino acids and of folly silgars were added to the substrates of red ginseng powder and these were then extracted and concentrated to examine their browning intensities. Amino acids were more effective than sligars in acrelerating the browning reaction. Acceleration of the browning reaction in the concentrate was in the order of arginine> histidine>glycine>alanine>lysine phenyl alanine>aspartic acid>lelicine>threonine>gllitamic acid>tyrosine>valine>istleucine>methionine for amino acids, and was glucose>frlictose >silcrose, maltose for sugars.

Background: Explosive puffing can induce changes in the chemical, nutritional, and sensory quality of red ginseng. The antioxidant properties of ethanolic extracts of red ginseng and puffed red ginseng were determined in bulk oil and oil-in-water (O/W) emulsions. Methods: Bulk oils were heated at $60^{\circ}C$ and $100^{\circ}C$ and O/W emulsions were treated under riboflavin photosensitization. In vitro antioxidant assays, including 2,2-diphenyl-1-picrylhudrazyl, 2,2'-azinobis-3-ethyl-benzothiazoline-6-sulfonic acid, ferric reducing antioxidant power, total phenolic content, and total flavonoid content, were also performed. Results: The total ginsenoside contents of ethanolic extract from red ginseng and puffed red ginseng were 42.33 mg/g and 49.22 mg/g, respectively. All results from above in vitro antioxidant assays revealed that extracts of puffed red ginseng had significantly higher antioxidant capacities than those of red ginseng (p < 0.05). Generally, extracts of puffed red and red ginseng had high antioxidant properties in riboflavin photosensitized O/W emulsions. However, in bulk oil systems, extracts of puffed red and red ginseng inhibited or accelerated rates of lipid oxidation, depending on treatment temperature and the type of assay used. Conclusion: Although ethanolic extracts of puffed red ginseng showed stronger antioxidant capacities than those of red ginseng when in vitro assays were used, more pro-oxidant properties were observed in bulk oils and O/W emulsions.

This study was performed to find out the quality characteristics of rice noodles by addition of red ginseng(0, 2, 6, 10%). The quality characteristics of the sample were estimated in terms of general composition, growth of microorganism and sensory evaluation. The results from this study were as follows. The protein, lipid and ash contents did not show significant difference in any of the groups. In dry rice noodles, moisture content significantly decreased in red ginseng groups but, in half-cooked rice noodles, moisture content significantly increased in 6 % and 10% red ginseng added groups(p<0.05). The microbial count showed less growth in red ginseng added groups after 3 months(p<0.05). According to sensory evaluation, surface color proved very good in the 10% red ginseng added group among the training panel while very good in the 2% red ginseng added group among consumers. Flavor was good in red ginseng added groups(p<0.05). Taste was very good in the 3% red ginseng added group. Appearance and overall quality were highest in the 2% and 6% red ginseng added groups(p<0.05). Therefore, rice noodles containing 2% or 6% red ginseng were most preferable and safe during 5 months and 6 days in dry and half-cooked noodles respectively.

This study was performed to find out the quality characteristics of Noodles by addition of red ginseng powder(0, 2, 4, 6, 8%). The quality characteristics of the sample were estimated in terms of general com-position, color difference, cookery characteristics(water absorption, volume of cooked noodles, turbidity), texture profile analysis and sensory evaluation. The protein, lipid, ash, Na and water binding capacity did not show significant difference in any of the groups. In red ginseng powder added groups, moisture contents, a and b values significantly increased but L value considerably decreased(p<0.05). The weight, volume, water absorption of the cooked noodles and turbidity of 8% of red ginseng powder added group were significantly higher than the control group(p<0.05). In texture profile analysis, adhesiveness, gumminess, hardness and springiness significantly decreased(p<0.05) with more red ginseng powder added. Chewiness and cohesiveness significantly(p<0.05) increased with the 4, 6, 8% of red ginseng powder added. In sensory evaluation, surface color was very good in the 8% red ginseng powder added group while taste and flavor of red ginseng were very good except the 8% red ginseng powder added group(p<0.05). Appearance and overall quality were highest in the 4% red ginseng powder added group(p<0.05). Therefore, noodles containing 4% red ginseng powder were most preferable.
