Objectives : We investigated the anti-aging effects on skin with 9 Repetitive steaming and fermenting herbal composition extract (FHE). Methods : Herbal composition is comprised of Panax Ginseng, Rehmannia glutinosa, Polygonum multiflorum and Polygonatum Sibiricum. They steamed and fermented with Saccharomyces cerevisiae and Lactobacillus brevis by turns at 9 times. We measured various effects related to skin aging such as scavenging activity against free radical, cell proliferation, collagen synthesis and toxicity of 9 repetitive steaming and fermenting herbal composition extract were evaluated and compared with herbal composition extract (HE). Results : As the number of steaming and fermenting cycle increased free-radical scavenging activity were increased. But cell proliferating ratio was not increased when the number of steaming and fermenting cycle. The FHE could significantly increase the collagen synthetic ratio compared with HE treated group. And, FHE was showed no toxicity at all tested concentrations. Conclusions : The results of our study propose that FHE has good anti-aging effects on skin.

In order to save foreign currency and to domesticize the dairy products, various fresh cheeses and whey drinks were developed and some physicochemical, microbiological and sensory evaluation were performed. The yield of fresh cheese was 22.3%, while that of whey 77.7%. The pH-values of fresh cheeses were $5.90{\sim}6.49$, while those of whey drinks $6.07{\sim}6.49$, and fermented whey drinks $3.97{\sim}4.91$. The acidities of fresh cheeses were $0.09{\sim}0.26%$, while those of whey drinks $0.09{\sim}0.36%$. The contents of solid substances, protein and lactose in fresh cheeses were $25.67{\sim}34.18%$, $7.45{\sim}9.11%$ and $3.61{\sim}4.14%$, while those of whey drinks $7.39{\sim}7.70%$, $0.88{\sim}0.94%$ and $4.93(\sim}6.17%$, respectively. The lactic acid contents of whey drinks varied from $0.01{\sim}0.38%$, where the content in the fermented sample was the highest. The general colony counts of fresh cheeses were $0{\sim}30/g$, while those of whey drinks $0{\sim}80/ml$. The psychrotrophs counts of fresh cheeses were $0{\sim}20/g$, while those of whey drinks $0{\sim}60/ml$. Lactic acid bacterial counts in both products were not detected except for $97{\sim}401{\times}10^8/ml$ in fermented whey drinks. E. coli and fungi were not detected in both products. In sensory evaluation of both products, the strawberry added fresh cheese was the best of fresh cheeses, while the garlic added fresh cheese was the worst. Pure whey drink was the best of whey drinks, while the ginseng added whey drink was the worst.

In the current food sanitation regulation, food additives are under controlled by the Food Code. The naturally derived preservatives such as benzoic acid and propionic acid can be naturally carried over or produced as metabolites during manufacturing process such as fermentation. To monitor naturally formed benzoic acid and propionic acid levels, a total of 145 samples were classified into berries (prune, cranberry), functional foods (propolis liquid, ginseng product), vinegars (vinegar-based drink, vinegar beverage, vinegar), and salted and pickled products (olive, pickled cucumber, salted/pickled product) and analyzed by HPLC-PDA and GC-FID. From the results, benzoic acid and propionic acid were each detected and identified in 144 samples and 64 samples respectively. The amount of benzoic acid ranged from $4.1{\sim}478.4\;ppm$ in cranberry, from $49.7{\sim}491$ in propolis liquid, and from $2.5{\sim}10.2\;ppm$ in ginseng, and other tested samples contained very small quantity. Also, the amount of propionic acid ranged from $179.8{\sim}951.9\;ppm$ (av. 553.6 ppm) in vinegar (persimmon vinegar 100%), which was the highest level among fermented foods, from $13.7{\sim}247.0$ ppm in propolis liquid, from $2.0{\sim}180.7\;ppm$ in vinegar-based drink, and from $1.6{\sim}76.6\;ppm$ in olive. Vinegar beverage and pickled cucumber each showed 24 and 18 ppm of propionic acid; in contrast, propionic acid was not detected in prune, cranberry, ginseng, and picked/salted products.

Western countries came to Asia aggressively in the early 1900s. Westerners who came to Korea at that time also had a various jobs with diplomats, missionaries, doctors, and so on. Korean diet was curious and shocking to foreigners in the early 1990s, so they made a record of the Korean diet. They thought Korea was peaceful, attractive and rich to eat. Koreans ate mainly rice and kimchi, a variety of grains, vegetables and bibimbap. Korea had a variety of meat and fish, seaweed, and herbs(ginseng). Foreigners said Koreans were greedy for food and ate a lot. Koreans ate basically a bowl of rice(bap), a bowl of soup(kuk), kimchi, soy sauce and other dishes. If Koreans wanted to set a table in abundance, they have meat soup(kuk) with meat and additional fish like as raw fish, dried fish, and boiled or fried fish. Korean people had a jangdokdae with Ongki(Earthen jar) where soy sauce(kanjang), soybean paste(doenjang), red pepper paste(kochujang), pickles (jang-achi) have been fermented. Foreigners felt the smell of lacquer tree and kimchi hung in the air from Korean people. While they were compared it to the smell of western rim cheese burger, they said Korea was a country with nasty smell in the feet. By the records of foreigners in the early 1900s, Korean's diets and image were appeared objectively.

As a series of study on the hygienization and long-term storage of dried red pepper and red pepper powder using gamma irradiation, water activity and fatty acid composition were monitored for stored samples. In proximate composition of dried pepper, moisture contents were 21.75 % in pericarp and 9.30% in seed, and crude fats were 7.20% (fresh wt.) in pericap and 22.50% in seed, respectively. Proximate components were stable against irradiation up to 10 kGy. Moisture contents and water activity of packaged samples in PE (0.1mm)/polycloth (whole pepper) and in nylon $15\;{\mu}m/PE\;100\;{\mu}m$ (pepper powder) were not remarkably changed during storage for 9 months under room temperature $(3{\sim}30^{\circ}C,\;RH\;50{\circ}95%,\;whole\;pepper,\;powder)$ and low temperature $(5{\sim}10^{\circ}C,\;pepper\;powder)$, respectively. Fatty acids of dried red pepper were mainly composed of linoleic acid, oleic acid, palmitic acid and linolenic acid. Particularly higher composition of unsaturated fatty acids were observed in seed $(84{\sim}85%)$ than in pericarp $(73{\sim}76%)$, and which showed negligible changes during post irradiation period for 6 months.

The headspace flavors of roasted tea, prepared with steamed and nonsteamed polygonatum roots, were absorbed in solid-phase microextraction(SPME) fiber coated with $65\;{\mu}m$ of carbowax/divinylbenzene(CW/DVB) and analysed by GC-MS. The absorption conditions of SPME fiber for equilibrated headspace were selected as $60^{\circ}C$ and 30 min. In a comparison for both samples roasted at $130^{\circ}C$ for 15 min, gas chromatograms showed a similar pattern in overall profiles between steamed and nonsteamed samples before roasting, but some differences were observed in peak characteristics. From 40 separated peaks, 25 compounds were identified with both GC-MS and retention time comparison. The pyrazines including 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one, 2,5-dimethyl-4-hydroxy-3(2H)-furanone, 2-acetyl-1-pyrroline, etc. were higher in their contents in nonsteamed-roasted sample than steamed-roasted one. In particular, steamed-roasted polygonatum showed higher contents of acetic acid(8.17%) and hexanoic acid(5.43%) than the corresponding compounds of nonsteamed-roasted one, 2.40% and 2.00%.

Objective : The aim of this study is to analyze medicinal herbs, the ingredients of traditional Korean liquor, focusing on efficacy in the traditional Korean medicine. Through this study, for vitalizing traditional Korean liquor market, the researchers attempt to explain the superiority of traditional Korean liquor and the advantages of using herbs to brew alcoholic beverages. Method : We conducted a research targeting traditional Korean liquors in domestic market from July through september 2012, and finally 70 kinds of liquor were selected and analyzed. Results : Among traditional liquors, fermented liquors are most common. When comparing regions of brewery, the central region of Korea, Gyeonggi-do and Chungcheongnam-do, is major brew area. 37 liquors contain just one medicinal herb. followed 10 liquors contain two medicinal herbs. The most frequently used medicinal herb is Ginseng Radix. And Lycii Fructus, Schisandrae Fructus, Angelicae Gigantis Radix and Chrysanthemi Indici Flos are well used medicinal herbs to brew traditional liquors. In the classification of efficacy of medicinal herbs, tonifying and replenishing medicinal herbs are most popular as ingredients in the traditional alcohols, astringent medicinal herbs, exterior releasing medicinal herbs and heat clearing medicinal herbs are also frequently used. Investigation of tastes and properties of the herbs, it reached a conclusion as below: sweet taste is most common, followed by sour taste and bitter taste. Warm property is account for 50% approximately, followed by cold property. Conclusion : Medicinal herbs have been widely used in the traditional Korean liquor. It came out into the open that the liquor with medicinal herbs is very good for our body in terms of longevity and invigoration. However, liquor consumers concern about not only the efficacy but also the taste, scent and color. Therefore, further study about these things would be required to demonstrate the superiority of the traditional Korean liquor.

The chemical and organoleptic properties of dongchimi studied for their changes during fermentation at $4{\sim}35^{\circ}C$ in 7% NaCl solution with seasonings. It was found that pH decrease showed three variation points in its slope at about pH 5.2, 4.7 and 4.1 during fermentation. A negative linear relationship between total acidity and logarithmic value of pH was obtained. The slope of the relationship curve was increased as the fermentation temperature increased. The reducing sugar was increased until pH reached$4.0{\sim}4.2$ followed by a small decrease and its amount was lowered as the temperature increased from $4\;to\;25^{\circ}C$ The major nonvolatile organic acids were lactic and citric acids. The increase in lactic acid were more marked at $25^{\circ}C$ than at $4^{\circ}C$. As fermentation proceeded the fresh radish odor significantly decreased while sourness and yeast-moldy odor increased. The crispness of the radish decreased slightly during fermentation.

The purpose of this study was to investigate whether the activity of ginsenoside metabolites and the intestinal immunity antioxidant activity were remarkably improved by lactic acid bacteria fermentation by adding a small amount of ginsenoside to the complex extracts of fruits and vegetables. It was confirmed that the increase in intestinal immunity antioxidant activity due to synergistic effect was observed in the fruit-vegetable extract containing ginsenoside compared to the ginsenoside-only extract or the fruit-vegetable extract. Then, by adding ginsenosides by content, the concentration of ginsenosides that can obtain a synergistic effect according to the fermentation of lactic acid bacteria was determined. As a result, it was confirmed that a synergistic effect was exhibited when lactic acid bacteria were fermented and extracted by mixing ginsenosides in a mass ratio of 3 to 10% with respect to the mass of the fruit-vegetable mixture. As a result, when treated at a concentration of 200 ㎍/ml, the fruit-vegetable complex extract containing ginsenoside metabolites inhibited the generation of NO by about 60% compared to the complex extract containing no ginsenoside, The expression of IL-1β was suppressed by 63%, the expression of IL-6 by 69%, and the expression of TNF-α by 76%, confirming that the intestinal immune antioxidant properties were significantly improved.
