This study was performed to investigate the changes in chemical composition of Panax ginseng leaf by harvesting at July, August and September. The levels of crude protein of dried ginseng leaf were decreased from 17.12mg% to 14.26% by harvesting month, however, crude fat contents of dried ginseng leaf were increased slightly from 1.90% to 2.49%. Three kinds of free sugar, i.e. glucose, fructose and sucrose were found in dried ginseng leaf and maltose was not found. Free sugar contents were increased by delaying harvest, but free amino acid were decreased. Total free amino acid was decreased in delayed harvesting month, serine was revealed superior in free amino acid composition, and valine was revealed next order. In minerals, contents of Ca were from 1,306.1mg% to 1,923mg%, that of K were higher than others patricualy as 1,266.9∼1,216.0mg%. The contents of minerals were existence in order of Mg, P, Na, Fe, Mn, Zn and Cu, abundantly. Total vitamin C were present of 391.0∼336.1mg%, and the contents were decreased as delayed as harvesting period despite of the plentiful content. In fatty acid composition of ginseng leaf, the palmitic acid content was as 40% higher than other fatty acids, remarkably.

In this review quality improvement, new products and processing of ginseng are discussed. Ginseng products are generally classified into two types; the dried product without significant change in original shape of fresh ginseng and various processed ginseng products in liquid or solid types prepared by addition of either ginseng extract of ground powder. The dried ginsengs are generally made 4 years old fresh ginseng roots for production of white ginseng and 6 years old ones for red ginseng. The processed ginseng products, such as ginseng drinks, extracts, teas, powders, capsules or tablets are prepared by addition of extract or powder of the ginseng roots which contain relatively high amount of saponin. At present, more than 200 items of 40 types of products are commercially available in over 70 countries in the world, Since consummers preference on the quality of ginseng products as an health food differs with their cultural background of each country, new products development and quality improvement should be investigated with concerning the particular preference of the consummers of various country. It has been generally found that the Orientals has higher product acceptance on strong ginseng flavor while the Westerners generally prefers the products having mild ginseng odor and taste. Recently consummers are asking for supplemented type of ginseng products with various medical herbs and vital materials instead of ginseng alone. Therefore future work on product development should be emphasized to meet the consummers demand and preference.

We compared the germination rate of dehisced ginseng (Panax ginseng) seeds that were dried under two different conditions, slowly at $15^{\circ}C$ [relative humidity (RH) 10-12%] and rapidly under a laminar airflow cabinet at $25^{\circ}C$ (RH 22-25%). The measurements showed that drying rate and seed moisture content (SMC) play important roles in storage ability and vigor. The seeds that were dried rapidly at $25^{\circ}C$ showed high GR compared with the seeds that were dried at $15^{\circ}C$ after 6 and 12 months of storage at $-80^{\circ}C$ irrespective of MC. Seeds dried slowly at $15^{\circ}C$ with MC higher than 7.0% showed high GR maintenance after storage at $-18^{\circ}C$ and at $4^{\circ}C$ in comparison with rapidly dried seeds. However, the GR of the slowly desiccated seeds decreased as mean SMC was reduced to less than 5.0%, whereas the rapidly dried seeds were distinguished by significantly high GR irrespective of the storage conditions. The ginseng seeds desiccated under different conditions showed differences in storage performance. Seeds with 7-9% MC that were dried slowly at $15^{\circ}C$ for 5-7 days showed high GR after $4^{\circ}C$ and $-18^{\circ}C$ storage; however, longer periods of desiccation decreased the germination level remarkably compared with that of rapidly dried seeds.

Studies were carried out to clarify the effect of ginsenoside-Rbl -Rbr and acid hydrolyzatps of ginsenoside-Rbl, -Rb2 (HRbl, HRbf) on lipolysis and lipogenesis induced by epinephrine, glucagon, ACTH (adrenocorticotrophic hormone), TSH (thyroid-stimulating hormone) and insulin in rat adipose tissilr. HRbl , HRb2 slightly inhibited lipolysis induced by epinephine. glucagon and TSH. ACTH-induced lipolysis in fat tissue slices was significantly inhibited by ginsenoside -Rbl, -Rb2, HRbl and HRb2, particulary HRb2. None of ginsenoside-Rbl, -Rb2, HRbl and HRb2 accelerated insulin-stimulated lipogenesis in fat calls. Among ginseng products, extract powder (freeze dried), extract powder (spray dried), red ginseng powder inhibited ACTH-induced lipolysis in adipose tissue slices, but red ginseng extract not affect them.

본 연구에서는 새로운 전처리를 통한 홍삼을 제조하여 홍삼의 향취미의 변화를 살펴보았으며 이로써 맛과 향이 개선 된 홍삼제품을 개발하고자 하였다. Acid(ascorbic acid, citric acid) 감압침투 방법으로 산처리 홍삼을 제조하였으며, 반 건조 산처리 홍삼과 반건조 홍삼의 색, 유리당, ginsenoside 함량, 관능검사를 실시하였다. 홍삼분말 색은 산을 처리하면 밝기 (L)와 황색도 (b)도는 감소하며, 적색도 (a)는 증가하는 것으로 나타났다. Fructose, glucose는 산을 처리하지 않은 홍삼이 가장 높았으나 sucrose, maltose는 citric acid 처리한 홍삼이 높게 나타나는 것을 알 수 있었다. Ginsenoside 함량은 산을 처리한 홍삼에서 $Rg_2+Rh_1$, $Rg_3$의 함량이 증가 되는 것을 알 수 있었다. 산을 처리한 반건조 홍삼과 일반 반건조 홍삼 관능검사에서는 색과 단맛에서만 유의적 차이가 나타났다. 그러나 건조 홍삼 추출물을 관능 검사한 결과 쓴맛과 떫은맛, 신맛, 향취, 색의 강도에서는 유의적 차이가 나타났다. 특히 산 처리한 홍삼 추출물은 쓴맛과 떫은맛이 감소되어 산으로 전 처리한 홍삼은 인삼에 대한 거부감을 줄일 수 있는 제품으로 사용 가능성을 보여 주었다.

This study was performed to develop a prototype continuous flow ginseng dryer with which better product quality and lower drying energy consumption could be achieved compared with conventional ginseng dryers. A dryer having both far infrared ray (IR) and heated-air as the drying energy sources was designed and fabricated . Dryer performance was studied by examining energy efficiencies and dryer performance evaluation indices (DPEI) during the drying tests of medium-sized four year ginseng roots with IR radiating plate temperature and drying air temperature in the range of 80-12$0^{\circ}C$ and 22-5$0^{\circ}C$, respectively. The DPEI of IR /heated -air combined drying was 1/3 of that of the conventional heated-air drying when ginseng were dried to the same final moisture ratio. When ginsengs were dried for 12 hours in the prototype IR/heated-air combination dryer, a linear relationship was found to exist between final moisture ratio and ginseng temperature. As the drying progressed, drying air temperature inside the dryer was nearly constant but ginseng temperature was drastically increased during the first two hours and gradually increased thereafter until the end of drying. With the prototype Ir/heated-air combination dryer, the drying rate changed little but the energy efficiency increased proportionally when the amount of ginseng to be dried increased. Drying capacity, energy efficiency, and DPEI of the prototype IR/heated-air combination ginseng dryer were estimated to 1.500 roots, 65% and 3.800kJ/kg-water , respectively.

Red ginseng and fermented red ginseng were prepared, and their composition of ginsenosides and antiischemic effect were investigated. When ginseng was steamed at 98-$100{\circ}C$ for 4h and dried for 5h at $60{\circ}C$, and extracted with alcohol, its main components were ginsenoside $Rg_3$ > ginsenoside $Rg_1$> ginsenoside $Rg_2$. When the ginseng was suspended in water and fermented for 5 days by previously cultured Bifidobacterium H-1 and freeze-dried (fermented red ginseng), its main components were compound K > ginsenoside $Rg_3{\geq}$ ginsenoside $Rg_2$. Orally administered red ginseng extract did not protect ischemia-reperfusion brain injury. However, fermented red ginseng significantly protected ischemica-reperfusion brain injury. These results suggest that ginsenoside Rh2 and compound K, which was found to be at a higher content in fermented red ginseng than red ginseng, may improve ischemic brain injury.

When saponin extracts of dried ginseng and red ginseng were anaerobically incubated with human intestinal microflora, these extracts were metabolized to compound K and ginsenoside $Rh_2$, respectively. However, when these extracts were incubated with commercial lactic acid bacteria, these did not metabolize these ginsenosides to compound K or ginsenoside $Rh_2$. Among some intestinal bacteria isolated from human feces, Bacteroides C-35 and C-36 transformed these saponin extracts to compound K and ginsenoside $Rh_2$, respectively. These bacteria also transformed water extracts of dried ginseng and red ginseng to compound K and ginsenoside $Rh_2$, respectively, similarly with that of the saponin extracts. Among transformed ginsenosides, compound K and 20(S)-ginsenoside $Rh_2$ exhibited the most potent cyotoxicity against tumor cells.

Ginseng is being distributed in 35 countries around the world and there are differences by each country in the distribution volume and amount. However, since there is no accurate statistics on production and distribution amount by each country, it is very difficult to predict the world ginseng market. Ginseng trading companies and governments are in desperate need of comprehensive data that shows the world ginseng market status for sales and marketing. For that reason, this study will look into the approximate size of the world ginseng market based on recent ginseng distribution amount by each country and production by major ginseng producing nations. In addition, the review sets an opportunity to check the status of ginseng (Korea) in the world and presents future direction by examining recent history of ginseng development in Korea, which is one of the world's largest ginseng distributers. Since ginseng is cultivated in limited areas due to its growth characteristics, ginseng distributing countries can be divided based on whether they grow it domestically or not. In general, four countries including South Korea, China, Canada, and the US are the biggest producers and their total production of fresh ginseng is approximately 79,769 tons which is more than 99% of 80,080 tons, the total ginseng production around the world. Ginseng is distributed to different countries in various forms such as fresh ginseng, dried ginseng, boiled and dried ginseng (Taekuksam), red ginseng and the related products, etc. and is consumed as food, dietary supplements, functional food, medical supplies, etc. Also, the world ginseng market including ginseng root and the processed products, is estimated to be worth $2,084 million. In particular, the size of the Korean market is $1,140 million which makes Korea the largest distributer in the world. Since the interests in alternative medicine and healthy food is increasing globally, the consumer market of ginseng with many features and the processed products are expected to expand continuously.
