Powders prepared from three different varieties of Korean ginseng (white, red and black) are consumed daily by many Koreans as a functional food material. These variants exert a variety of physiological effects. The principal objective of this study was to evaluate the quality characteristics of Yanggaeng prepared with three different types of ginseng powder. We conducted tests for ginsenosides content, Hunter's color values, mechanical characteristics, and sensory evaluation analysis. The ginsenosides of black ginseng were higher than those of white and red ginseng. The lightness of the black ginseng Yanggaeng was significantly less than the white, red, and control samples (p<0.05). We noted significant differences in Hunter's a and b values. With regard to the mechanical properties of the samples, we noted significant differences in gumminess (p<0.05), but no differences in hardness, springiness, chewiness, and cohesiveness were detected. The results of sensory evaluation showed that there were significant differences in the color, flavor, and overall quality of the samples (p<0.05), but there were no significant differences in taste and texture. Overall, red ginseng Yanggaeng appeared to have the most commercial value for improving the Yanggaeng product.

For the purpose of developing a safe & hygienic manufacturing method to acquire low levels of benzo(a)pyrene in black and red ginseng products, this study investigated the effects of steam- and dry-processing temperatures on benzo(a)pyrene production in ginseng. By the red ginseng with a fix dry-process temperature of $50^{\circ}C$ and setting the steam-process temperature between $80{\sim}120^{\circ}C$, an extremely small amount(0.1 ppb) of benzo(a)pyrene was produced, indicating there was no relationship between the steam-temperature and benzo(a)pyrene production. On the other hand, when the red and black ginseng were steamed at the fixed temperature of $100^{\circ}C$ and dried at various temperatures between $50{\sim}120^{\circ}C$, the amount of benzo(a)pyrene produced was closely connected with the dry-temperature, and increased with higher drying temperatures. Upon repeating the steam and dry process nine times, in which the steam-temperature was set at $100^{\circ}C$ and the dry-temperature at $50^{\circ}C$, higher amount of benzo(a)pyrene were produced in red and black ginseng, respectively, with increasing steam- and dry-processing time. However, the level of benzo(a)pyrene still remained extremely small(below 0.12 ppb), showing a maximum amount in the black ginseng that was steamed and dried nine times. This suggests that the fine root of ginseng may be carbonized by increasing the number of times it is steam- and dry-processed. From the above results, this study determined that the optimum temperatures for manufacturing red and black ginseng products with safe levels of benzo(a)pyrene would be a temperature between 80 and $120^{\circ}C$ for steaming and a temperature less than $50^{\circ}C$ for drying.

Background: Ginseng black spot disease resulting from Alternaria panax Whuetz is a common soil-borne disease, with an annual incidence rate higher than 20-30%. In this study, the bacterial strains with good antagonistic effect against A. panax are screened. Methods: A total of 285 bacterial strains isolated from ginseng rhizosphere soils were screened using the Kirby-Bauer disk diffusion method and the Oxford cup plate assay. We analyzed the antifungal spectrum of SZ-22 by confronting incubation. To evaluate the efficacy of biocontrol against ginseng black spot and for growth promotion by SZ-22, we performed pot experiments in a plastic greenhouse. Taxonomic position of SZ-22 was identified using morphology, physiological, and biochemical characteristics, 16S ribosomal DNA, and gyrB sequences. Results: SZ-22 (which was identified as Brevundimonas terrae) showed the strongest inhibition rate against A. panax, which showed 83.70% inhibition, and it also provided broad-spectrum antifungal effects. The inhibition efficacies of the SZ-22 bacterial suspension against ginseng black spot reached 82.47% inhibition, which is significantly higher than that of the 25% suspension concentrate azoxystrobin fungicide treatment (p < 0.05). Moreover, the SZ-22 bacterial suspension also caused ginseng plant growth promotion as well as root enhancement. Conclusion: Although the results of the outdoor pot-culture method were influenced by the pathogen inoculum density, the cropping history of the field site, and the weather conditions, B. terrae SZ-22 controlled ginseng black spot and promoted ginseng growth successfully. This study provides resource for the biocontrol of ginseng black spot.

The aim of this study was to examine the ameliorating effect of black ginseng on the growth of the HepG2 cell transplanted tumor in BALB/c nude mice. 27 male BALB/c nude mice (all six weeks old) were randomly divided into three groups: the control group, the first treatment group (HepG2300RG, using 300 mg/kg red ginseng), and the second treatment group (HepG2300BG, using 300 mg/kg black ginseng). The HepG2300BG in the HePG2 cells showed increased mean survival time than that of red ginseng group. The size and volume of the tumor in the 300BG group showed significant reduction compared to those of the HepG2300RG group (p<0.05). The body weight and liver weight of the HepG2300RG group was not significantly different with control and HepG2300BG group. The serum levels of ALT and AST in the HepG2300RG and HepG2300BG group were significantly lower than those of the control group. In conclusion, these results suggest that the black ginseng may have possible anti-tumor activities.

The objective of this study is to provide the basic information for developing a high-value ginseng product using ginseng saponin and prosapogenin. In order to achieve such aim, Ginsenoside compositions of black ginseng (BG) extracts with various solvent conditions were examined by HPLC. The total saponin and the prosapogenin content of 95$\%$ ethyl alcohol extract were higher than that of the either 50$\%$ ethyl alcohol extract or distilled water extract. As a result, the order of the total saponin and the prosapogenin content was 1) 95$\%$ ethyl alcohol,2) 50$\%$ ethyl alcohol,3) the first and second mixture of 95$\%$ ethyl alcohol, distilled water, and 4) distilled water extract. In the case of fine black ginseng (FBG), the first and second mixture extracts of 95$\%$ ethyl alcohol and distilled water were the highest. In addition, the ratio of the protopanaxadiol group and the protopanaxatriol group (PD/PT) showed that the ratio of BG ranged from 0.304 to 0.601, while the ratio of FBG ranged from 1.166 to 1.657.

Streptozotocin-유도 당뇨병 모델을 이용하여 흑삼의 혈당강하작용에 대한 효과를 연구하고 증포과정에 따른 ginsenoside의 조성 변화를 분석하였다. 증포별 ginsenoside의 정량분석 결과, 증포 횟수가 증가할수록 조사포닌의 총량과 대부분의 ginsenoside는 줄어든 반면 ginsenoside-$Rg_3$ 함량 및 PD/PT 비율은 증가하는 경향을 보였는데, 이러한 조성은 다른 인삼제품과는 차별성 있는 특징이다. 또한, streptozotocin-당뇨병 유발쥐를 이용한 모델실험에서 흑삼추출물의 투여는 고혈당 준위(300 mg/dL이상)를 정상 수준(102 mg/dL)으로 감소시켰으며, 혈당 수준의 감소는 glycolysis나 HMT shunt 및 지방산 합성에 관여하는 glucokinase, glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, acetyl CoA carboxylase 등의 효소의 활성증대에 기인하는 것으로 판단되었다. 이러한 결과는 흑삼추출물의 유의적인 혈당강하 효과를 입증하며 이에 따라 신약이나 식이보조제의 항당뇨물질로서의 이용가능성을 시사한다.

Black ginseng is produced by a repeated steaming process. The aim of this study was to investigate the anti-obesity effects of black ginseng ethanol extract (BG-EE) in high fat (HF) diet-fed mice. Two groups were fed either a normal control (NC) diet or a HF diet (45% kcal fat). The other three groups were given a HF diet supplemented with 1% BG-EE, 3% BG-EE, and 5% BG-EE for 12 wk. The anti-obesity effects of the BG-EE supplement on body weight, the development of fat mass, and lipid mechanisms were assessed in obese mice. HF-induced hyperlipidemia, fat accumulation in the liver, and white adipose tissues were reduced after BG-EE supplementation. Total fecal weight and the amount of fecal fat excretion also were increased after BG-EE supplementation. These results suggest that BG-EE may be useful to ameliorate HF-induced obesity through the strong inhibition of fat digestion.
