Background: Ginsenosides, which have various physiological activities, are known to be abundant in the leaves and roots of ginseng. Ginseng sprouts can be used as a fresh vegetable and roots, stems, and leaves of ginseng can be consumed. This study aimed to investigate the effect of carbon dioxide treatment and the modified atmosphere (MA) packaging method in suppressing quality deterioration during the distribution of ginseng sprouts. Methods and Results: Ginseng sprouts were packed using Styrofoam, barrier film + non gas treatment, barrier film + gas treatment, 15 ㎛ polyamide (PA) double film + non gas treatment, 15 ㎛ PA double film + gas treatment, 25 ㎛ PA film + non gas treatment, or 25 ㎛ PA film + gas treatment. Quality parameters including gas composition, relative humidity, chlorophyll SPAD (Soil Plant Analysis Development) value, firmness, and rate of quality loss in ginseng sprouts were monitored at the following temperatures: 20℃, and 10℃. Ginseng sprouts packaged with 25 ㎛ PA film showed loss in quality because of wilting owing to low relative humidity within the film. Chlorophyll and firmness did not differ between film and gas treatments. The time point at which the combined loss from softening and decay owing to fungal, and bacterial infection and wilt reached 20% was considered the limit of distribution. At 20℃, the packaging not included in the 20% distribution loss rate limit or up to 7 days was 15 ㎛ PA double film + gas treatment. At 10℃, the packaging not included in the 20% distribution loss rate limit for up to 18 days were barrier film + gas treatment and 15 ㎛ PA double film + gas treatment. Conclusions: The film packaging suitable for the distribution of ginseng sprouts was found to be the barrier film and PA film with low gas permeability and maintaining hygroscopicity at 95% relative humidity. To prevent the loss in quality of ginseng sprouts, gas treatment (8% of O₂ and 18% of CO₂) in the film was found to be more suitable than no gas treatment for inhibition of decay.

Background: Since the revised Ginseng Industrial Act was passed, ginseng sprouts have become a new medicinal vegetable for which there is high consumer demand. However, the existing amount of research and data on ginseng production has not kept pace with this changed reality. Methods and Results: In this study we analyzed the changes in the amounts of ginsenosides in different parts of growing ginseng sprouts during the period from when organic seedlings were planted in nursery soil until 8 weeks of cultivation had elapsed, which was when the leaves hardened. In the leaves, ginsenoside content increased 1.62 times with the panaxadiol (PD) system and 1.31 - 1.56 times with the panaxatriol (PT) system from 7 to 56 days after transplantation. During the same period, the total ginsenoside content of the stems decreased by 0.66 - 0.91 times, and those of the roots increased until the $21^{st}$ day, and then underwent steep declines. The effect of fermented press cake extract (FPCE) and tap water (TP) on the total amount of ginsenoside per plant were similar, and could be represented with the equations $y=1.4330+0.2262x-0.0008x^2$ and $y=0.9555+0.2997x-0.0031x^2$ in which y = ginsenoside content x = amount of and on the total amounts of FPCE or TP, respectively after 26.4 days, however, the difference between ginsenoside content with FPCE and TP widened. Conclusions: These results suggested that the amounts of ginsenosides in different parts of ginseng varied with the cultivation period and nutrient supply. These findings also provide fundamental data on the distribution of ginsenosides among plant parts for 2-year-old ginseng plants in the early-growth stage.

This study evaluates the microbial safety of ginseng sprouts packaged in moss and a modified atmosphere (MA) film within Styrofoam boxes. Ginseng sprout samples were stored at 4℃ for seven days, and the total fungi and aerobic bacteria counts, relative humidity, and moisture content were measured at 0, 1, 3, 5, and 7 days. During the storage period, both packaging treatments caused an increase in the total fungi and aerobic bacteria counts. However, by the seventh day, the ginseng sprouts packaged in the MA film demonstrated significantly lower counts of total fungi (3.03 log CFU/g) and aerobic bacteria (7.32 log CFU/g) than those in moss (3.66 and 7.63 log CFU/g, respectively). Moss packaging alone resulted in the total fungi count reaching up to 3.36 log CFU/g, with the aerobic bacteria count consistently exceeding 7 log CFU/g, highlighting the importance of hygienic management. Moreover, no significant differences were observed in the moisture content and relative humidity between the MA-film- and moss-packaged groups throughout storage. These findings indicate that the functional MA film is a more hygienic packaging solution for ginseng sprouts than moss.

The study was conducted to identify the anti-inflammatory and anti-cancer effects in sprouts of mouse-eyed bean (Rhynchosia nulubilis), ginseng (Panax ginseng), perilla (Perilla frutescens), broccoli (Brassica oleracea var. italica), and lettuce (Lactuca sativa) grown with organic germanium concentrate. Western blot analysis was performed to assess the anti-inflammatory activity of the extract. All extracts exhibited noticeable anti-oxidant activity, indicating a significant correlation between the germanium content and anti-oxidant activity (p<0.05). In particular, rat-eyed bean sprouts with the highest germanium content showed significant anti-inflammatory activity (p<0.05) by significantly inhibiting the expression of the inflammatory complexes, NLRP3, cytokines IL-1β and caspase-1. Ginseng and broccoli sprouts showed strong anti-cancer properties and had high anti-oxidant effects (p<0.001). Germanium-concentrated water allows the mass production of agricultural products containing high concentrations of organic germanium. Agricultural produce grown with germanium concentrate add organic germanium to various physiological active ingredients, increasing the anti-oxidant and anti-cancer effects. These results strongly suggest that agricultural products containing high germanium concentrations can be used as novel health supplements to improve health.

인삼추출물(100∼400 ppm)로 콩을 발아시켜 4일간 재배한 콩나물의 생육특성, 아미노산, 유기산 및 유리당 함량의 변화를 조사하였다. 인삼추출물은 콩나물의 길이 및 무게증가에 효과적이었다. 총 아미노산 함량은 100 ppm에서 3일간 재배하였을 때가 가장 높았고, 추출물의 농도가 높을수록 그 함량이 많아졌다. 또한 재배일수가 길어질수록 aspartic acid 함량은 증가하지만, glutamic acid 함량은 오히려 감소하는 경향을 나타내었다. 총 유리당은 재배일수가 증가할수록 많아졌으나, 농도별로는 일정한 경향이 나타나지 않았다. Sucrose는 대조구에서 점진적으로 감소하였고, 추출물 처리구는 3일까지는 증가하다가 그 이후는 감소하였으며, 다른 유리당은 4일까지 지속적으로 증가하였다. 총 유기산은 인삼추출물 200 ppm으로 발아시켜 3일 동안 재배한 콩나물이 가장 많은 함량을 나타내었다. 그 중에서 phytic acid가 가장 많았으며, 총 유기산의 45∼60% 정도를 차지하였다. 결론적으로 인삼 추출물을 콩의 발아액으로 활용하면, 콩나물의 성장촉진, 아미노산, 유기산 및 유리당 함량의 증진에 효과가 있는 것으로 나타났다.

Background: The ginseng ginsenosides, which have various physiological activities, are known to be more abundant in the leaves than in the roots, and the consumers' interest in ginseng sprout as a functional vegetable has been increasing. Methods and Results: The aim of this study was to investigate the effects of growth period on growth properties, active ingredients and rheology of ginseng sprouts cultivated in a non-heated greenhouse equipped with a shade net for 60 days, starting from the end of May to the middle of July. The chlorophyll content of the leaves decreased, but their length and width increased with increasing cultivation days. In particular, growth increased significantly until 40 days, but only slightly after 50 days. The stem length did not increase greatly from the 20 th to the 30 th day of cultivation, but increased significantly from the 30 th to the 40 th day, and then further increased gradually. The weight of the leaves, stems, and roots increased slightly, but not change significantly. After 40 days of cultivation, the total ginsenoside content increased by 1.07 times in the leaves and decreased by 0.80 times in the roots with increasing cultivation days. The leaf contents of ginsenosides $Rg_1$, Re, $Rb_1$, Rc, $F_3$ and $F_4$ increased with increasing cultivation days. The rheological properties of ginseng sprout showed the greatest influence on stem hardening with increasing cultivation days. Conclusions: Therefore, based on the growth characteristics, active ingredients and physical properties, 40 days after sowing was considered to be an appropriate harvesting time for ginseng sprouts.

Ditylenchus destructor isolated from diseased ginseng roots was cultured on ginseng calli, fungal mycelium (Fusarium solani), carrot discs and radish sprouts. Effects of temperature, organic material and flooding on the nematode population changes were examined. D. destructor multiplied readily on the culture media except radish sprout medium, and was cultured best on the fungal culture at 2$0^{\circ}C$. Feeding of the fungal hypha and radish root hairs, molting and mating in the fungal culture medium were observed. Addition of organic materials (perilla, sesame, soybean and ginseng leaves) in soil significantly increased Aphelenchus avenae and saprophytic nematode populations, while D. destructor populations changed little and the nematode population growths were limited by the organic amendments (except sesame leaves). The nematode populations in soil including D. destructor were decreased by flooding. The results indicate that D. destructor may survive but not multiply readily in soil without host plants and that it can be effectively controlled by flooding.
