This study evaluated the quality characteristics and antioxidant activities of cookies after adding black ginseng powder at ratios of 0%, 1%, 3%, 5%, and 7%, and the potential of black ginseng as a functional food. The moisture content increased with an increase in the black ginseng powder content while the pH decreased. The L value decreased with increase in the black ginseng powder content while the a and b values increased. The hardness decreased with increase in the black ginseng powder content. Notably, antioxidant activities, such as 2,2-diphenyl-1-picryl-hydrazyl (DPPH), 2-2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid)diammonium salt (ABTS) radical scavenging showed the highest increases in cookies containing 7% black ginseng powder. The total phenol and flavonoid contents significantly increased according to the amount of black ginseng powder added. These results suggest that black ginseng powder can be applied to cookies to achieve high quality and antioxidant activity.

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.

Background: Black ginseng has a more potent biological activity than non-steamed ginseng. We investigated the effects of long-term intake of dietary black ginseng extract (BG) on antioxidant activity in aged mice. We also compared the effects of BG on cognitive deficits with those of white ginseng extract (WG) and red ginseng extract (RG). Methods: Ten-month-old mice were fed an AIN-93G-based diet containing 10 g/kg (low dose, L) or 30 g/kg (high dose, H) WG powder, RG powder, or BG powder for 24 wk. We measured serum lipids, the activities of antioxidant enzymes, and malondialdehyde levels. Additionally, the protein expression levels of choline acetyltransferase and vesicular acetylcholine transporter, which are presynaptic cholinergic markers in the cortex and hippocampus of the brain, were measured by western blotting. Results: Triglyceride levels were reduced in all the extract-treated mice, except those in the LBG group. High-density lipoprotein cholesterol levels in the HBG group were higher than those in the control group. Total cholesterol levels were reduced in the LBG group. Additionally, glucose levels in the HBG group were significantly reduced by 41.2%. There were lower levels of malondialdehyde in the LBG group than in the control group. Furthermore, glutathione reductase activity increased in the HWG group and the HRG group. The protein expression levels of choline acetyltransferase and vesicular acetylcholine transporter significantly increased in all the ginseng-treated groups. Conclusion: The results suggest that supplementation with the tested ginseng extracts may suppress the cognitive decline associated with aging, via regulation of the cholinergic and antioxidant defense systems.

Ginsenosides are major constituents of ginseng and are known to be responsible for its pharmacological properties. This study aimed to investigate the detoxification effect of a mixture containing black red ginseng powder, red ginseng extract, Puerariae radix extract, and Hovenia dulcis extract, on SD (Sprague Dawley) rats treated with 30% ethanol. Thirty minutes before treatment, the animals were orally administered different concentrations of the mixture or water. Results revealed that the concentration of ethanol in blood serum was significantly decreased in the black red ginseng mixture treated group in a dose-dependent manner, as compared with that of the control group. The blood level of acetaldehyde increased until 1 hr after alcohol administration, but the levels rapidly decreased later. Furthermore, ADH and ALDH activities in the hepatic tissue were also increased in the black red ginseng mixture administered group, than in the control group. These results indicate that the black red ginseng mixture has the ability of decomposing alcohol by increasing the ADH and ALDH activities responsible for alcohol metabolism.

We investigated the anti-obesity effects of Lactobacillus acidophilus C isolated from kimchi and red ginseng and black raspberry mixture fermented by this strain. Experimental samples were prepared with 10% skim milk, 1% red ginseng extract and 1% immature black raspberry powder and without red ginseng extract and black raspberry fermented by this strain at $37^{\circ}C$ for 24 hour. Male C57BL/6J mice were randomly divided into 4 groups (a normal diet group (N), a high-fat diet group (HF), a high fat diet with L. acidophilus C (C), and a high fat diet with fermented mixture (CEx)) and were orally administered daily for 6 weeks at concentration of 2,000 mg/kg body weight. The results showed that weight gain, weight of periepididymal fat and perirenal fat, adipocyte size, lipid accumulation in liver, serum glucose concentration, serum GOT and GPT concentration and serum leptin were decreased and concentration of HDL-cholesterol and serum adiponectin were increased compared to HF group. These results suggest that fermented mixture (CEx) might be helpful in improvement of high-fat diet-induced obesity than only L. acidophilus C intake.

This study was undertaken to evaluate the effects of green and taste teas on the in-vitro antimicrobial activity and vacuolating toxin titer of Helicobacter pylori. Crude aqueous extracts prepared by adding 2 g of tea leaf or powder to 100 ml of boiling distilled water, and sterilized by passing through a 0.22 $mutextrm{m}$ membrane filter. Green tea, coffee, and ginger tea showed bactericidal activity on H. pylori within 3 hours. Black tea and ssangwha tea also showed bactericidal activity on H. pylori in 24 hours. Arrowroot tea show no bactericidal effect on H. pylori after 48 hours. Two fold diluted green tea and coffee decreased(1/10,000cfu) the growth of H. pylori in 24 hours, but the two fold diluted black tea, ssangwha tea, and ginger tea showed suppression effect upon of(1/10cfu) H. pylori in 24 hours. The two-fold and 10-fold diluted green tea, coffee and two-fold diluted black tea abrogated the vacuolating toxin titer of H. pylori, but the two-fold and 10-fold diluted ginger, ssangwha, ginseng, and arrowroot tea only reduced the vacuolating toxin titer of H.pylori from 1/2 to 1/8. These result suggest that green tea and coffee have effective antibacterial or bactericidal effects on H.pylori, and that they also have a neutralization effect upon the vacuolating toxin of H.pylori.

Acceptable fish noodles of better nutritional and sensory values than conventional noodle made only wheat flour were prepared by mixing wheat flour and ground tile fish (Branchioste gus japonicus). In oder to mask a distinctive fish odor, various herbs and spices, such as ginger (Zingiber officinale), curry (Chalcas koenigii), nutmeg (Myristica Pagrans), garlic (Ailium sativum), black pepper (Piper nigrum), lemon (Cirtus limon) or sodachi (Citrus sudachi) were added to the basic tile fish noodle. Also, for the purpose of enhancing eating qual ify and nutritional value of basic noodle were combined some agricultural or fishery products of Cheju island, citrus fruits; danyooja (Citrus danyooga), hagul (C. natfudaidai), medical plants; angelica utilis (Angelica keiskei), ginseng (Panax ginseng), cactus (Opuntia dillenii), vegetable; carrot (Daucus carota), dropwort (Oenanthe jnvanica), seaweeds; fusiforme (Hizkia fusiforme), gulfweed (Sargaceae hlvelium). The optimal mixing ratio for preparing the basic tile fish noodle amounted to ground tile fish 135 g: tile fish stock 139 $m\ell$: wheat flour 450 g: salts 10 g. The mixture of curry powder (2.5 g) and nutmeg powder (2.5 g) was proved to be the most effective combinations for masking unfavorable fish odor. The optimal amounts of materials to be added to the prepared basic noodle were 25 g citrus zest and 80m1 citrus juice for citrus fruits noodles, and ca. 140 g puree for noodles from medical plants, vegetables and seaweeds, respectively. The preference score obtained from consumer preference test, on a 9-point scales, were in oder of i) danyooja > carrot, angelica, ginseng > fusiforme, ii) hagul > dropwort, cactus > gulfweed. The shelf-life of tile fish noodle based on bacterial counting was estimated to be 7-days at 5$^{\circ}C$.
