This study was conducted to investigate changes in ginsenoside by continuously treating fine bubble, which are mainly used for environmental purification, in 2-year-old ginseng. The ginsenoside content and composition of ginseng leaves and roots were analyzed for 4 months (120 days) after application of Fine bubble. As a result of treatment with common water in leaves, only Re of protopanaxatriol was significantly higher and As a result of treatment with fine buble, it was confirmed that protopanaxadiol Rb1, RC, Rb2 and Rd components were also increased. Especially, the increase of Re and Rb1 resulted in an increase of total ginsenoside. The ratio of PD / PT to ginseng was 0.811 in finebubble treated leaves and 1.28 in root. The fine bubble treatment induced the synthesis of ginsenoside from the roots and resulted in a PD / PT ratio of close to 1. Therefore, this study suggests a method of cultivating high quality ginseng using fine bubble water and suggests possibility of using it as a functional food material which can be used with leaves as well as roots.

The aim of this study was to evaluate the potential of fermented red ginseng extract (FRGE) as feed additive in broilers and laying hens. In broilers, 480 Arbor Acre male broilers were randomly allotted to 4 treatments with 6 replications per treatment and 20 chicks per pen. The experiment lasted 5 weeks and dietary treatments were as follows: i) CON, basal diet; ii) FRGE1, basal diet+1 g/kg fermented red ginseng extract; iii) FRGE2, basal diet+2 g/kg fermented red ginseng extract and iv) FRGE3 basal diet+4 g/kg fermented red ginseng extract. Throughout the experiment, no effects were observed (p>0.05) in performance in response to FRGE. At the end of the experiment, FRGE administration improved (p<0.05) the lymphocyte level compared with CON. The relative weight of bursa of fabricius and spleen were increased (p<0.05) by the inclusion of FRGE3. Besides, redness ($a^*$) value for the breast meat was higher (p<0.05) in FRGE1 and FRGE3 treatments than that in CON. In laying hens, 240 ISA brown layers at 35 weeks of age were used in this 8-week trial. Dietary treatments were the same as in the broilers trial with 10 replicates per treatment and 6 layers per replicate. During the entire experiment, there were no significant differences (p>0.05) in performance or egg quality among all the treatments. However, the layers fed diets supplemented with FRGE had higher lymphocyte level (p<0.05) compared with those fed CON. In conclusion, the dietary supplementation with FRGE did not influence performance but improved the lymphocyte level in both broilers and laying hens.

Sprout ginseng paste were prepared with pine nut, dry oyster and dry shrimp to examine the antioxidant properties(total polyphenols, total flavonoids, and electron donating ability) and sensory test(attribute difference and acceptance). Sprout ginseng paste were measured based on color value, pH, viscosity, total bacteria cell numbers for 0 and 20 days at $4^{\circ}C$. The higher total polyphenol and total flavonoid content of sprout ginseng paste added with pine nuts, dry oyster, and dry shrimp were higher antioxidant capacity. DPPH radical scavenging activity was increased from 52.2% (SGP0) to 79.5.0 % with SGP5. The attribute test results reveal that the color intensity, bitter taste, and oily taste were decreased in SGP3 to SGP6. Taste, flavor, and coarseness did not show significant difference in SGP0 to SGP6. Thickness and After taste were increased in SGP4 to SGP6. The preference test results reveal that the appearance, flavor, and texture level did not show significant difference in SGP0 to SGP6. Taste and overall preference were increased in SGP4 to SGP6. L value, pH, decrease while a value and b value show no change in sprout ginseng paste with pine nut, dry oyster and dry shrimp. Total cell number was not detected during storage.

This study was carried out to get basic information that can be used in quality control for processing ginseng products and also in separation of pure ginsenosides for experimental purpose. The composition of various parts of 6 year-old ginseng was 4.1% of rhizome (node), 47.7% of main root, 34.1% of lateral root and 14.1% of fine Toot on dried weight basis. The weight ratios of epidermis-cortex and xylem were about 1 : 1 in main root and about 2 : 1 in lateral root. The distribution of total saponin content shows 29.2% in main root, 34.6% in lateral root, 29.1% in fine root and 7% in rhizome, but the order of the content per unit weight was fine root > rhizome > lateral root > main root. Total saponin content according to age of root was increased gradually within 3% for 6 years, as compared with two year old root. In view of the increase of root weight owing to the net amount of saponin in root increased continuously. The increase rates of total saponins per year were 3.1,12.3,19.8,43.8 and 21.1% in 2, 3, 4, 5 and 6 years-old ginseng root, respectively.

This experiment was carried out to select suitable organic matter in To-jik nursery (self soil nursery) for complement To-jik nursery's defects that are deterioration of raw material by poor quality of seed ginseng and reduction of the quantity in seed ginseng production. Organic matter used were Yacto, rice bean, defatted rice bran, soybean cake and their mixture. As follows, bulk density in soil physical property by treating organic composts was the greatest in soybean cake and the next was followed by mix, Yacto, defatted rice bran, and rice bran treatment in order. Soil pore space ratio was totally the opposite; that was rice bran the first and followed by defatted rice bran, Yacto, mix and soybean cake treatment. The incidence rate of damping off by treating organic composts was 1.5% in both soybean cake and mix while the others was 1.0%. Emergence time was the same among treatment on April 16 and Emergence rate was the highest at 73% in Yacto. There was no significant differences among treatment in the growth of aboveground part but it was a little better in defatted rice bran treatment. In Yacto treatment, the growth of underground part, total root number per kan, rate of first grade ginseng seedling, and rate of usable ginseng seedling etc. were entirely higher but there was little differences. Using defatted rice bran was slightly lower in productivity compared to Yacto, but the possibility was high as a alternative for Yacto in a view of managing cost down.

Red ginsengs are inspected manually by examining those in the dark room with back light illumination. Manual inspection is often influenced by physical condition of inspectors. Sometimes. the best grade, heaven. has some inner holes though it was inspected by a specialist. In order to resolve this problem, this study was performed to develop image processing algorithm to detect the inner holes in the x-ray image of ginseng. Because of little gray value difference between background and ginseng in the image. simple thresholding method was not appropriate. Modified watershed algorithm was used to differentiate the inner holes from background and normal ginseng body. Inner hole edge region detected by watershed algorithm consists of many number of blobs including normal portions. With line profile analysis with scanning one line at a time beginning the starting point. it shelved two peaks both ends representing extracting each blobs. in which setting threshold value as of lower peak value enabled us to obtain inner hole image. Once this procedure has to be done till the finishing point it is completing inner hole detection for one blob. Thus. conducting ail blobs by this procedure is completing inner detection of one whole ginseng. Detection results of the inner holes fer various size of red ginsengs were good even though there was small detection variation. 6.2%. according to position of x-rat tube.

Ginseng was stored at a temperature lower than the freezing point after a treatment of freezing point depressing agents to extend its freshness. Respiration rate at freezing point of ginseng, -1.7${\pm}$0.1$^{\circ}C$, was inhibited 92% and 97% compared with those stored at 5$^{\circ}C$or 20$^{\circ}C$ , respectively. Sorbitol solution chosen as a freezing point depressing agent lowered the freezing point of ginseng to about -3.0$^{\circ}C$. Ginsengs treated with the sorbitol solution and packaged with 0.06mm LDPE was stored at -2$^{\circ}C$ , and the quality change was then compared with ginsengs stored at 0$^{\circ}C$ and 5$^{\circ}C$. Weight loss of ginsengs stored at -2$^{\circ}C$ for 100days was 1.5%, which is about 2.6times less than those stored at 5$^{\circ}C$. However, there were no significant difference between the ginsengs stored at -2$^{\circ}C$ and at 0$^{\circ}C$(1.9%). Spoilage rate of the ginsengs was 100% after 50 days of storage at 5$^{\circ}C$ and 25% after 100days at 0$^{\circ}C$respectively. but that of ginsengs stored at -2$^{\circ}C$ was 13%, which was half than that of ginsengs stored at 0$^{\circ}C$. Firmness and amount of monoscaccharides in ginsengs were decreased during storage at 5 or 0$^{\circ}C$ but ginsengs stored at -2$^{\circ}C$ showed better firmness and an increase in monosaccharides such as fructose and glucose. From above, when ginseng treated with freezing pont depressing agents were stored at -2$^{\circ}C$, the shelf life was extended to 2 or 3 times longer than those that were stored at 5 or 0$^{\circ}C$, respectively.
