Korean medicinal herbs -sasam, gilkyung, jakyak, danggwi, hwangki and chunkung were soaked to the distillate of Korean rice wine for 75 days. The alcohol concentration of distillate, soaking media was adjusted to 45, 35, and 25% respectively with distilled water. Changes in alcohol concentration, pH, optical density, concentration of peoniflorin and decursin were analyzed. Quality of the final product was determined by sensory evaluation. Alcohol concentration was rapidly decreased but pH increased in 15 days and thereafter they showed slow decrease. Decrease of alcohol concentration was affected by the kind of herb and alcohol concentration of soaking media. The strongest effect was observed from danggwi and low alcohol concentration. Concentration of paeoniflorin and decursin, an index component of jakyak and danggwi respectively, showed the similar trend of decrease after increase to maximum concentration. From the sensory evaluation, the best overall quality was obtained from liquors made from 45% alcohol concentration. The quality was decreased in the order of sasam, jakyak, chunkung and hwanggi.

The purpose of this study was to examine the effect of supplementary highly purified chitosan (HPC) on blood alcohol concentration in healthy human. The human study was performed with two sections. Each section of the study was conducted by two-phase cross-over design with a week wash-out period. All volunteers took HPC in one phase, and took a placebo in the next phase. Blood alcohol concentrations were different between in those taking HPC and in those taking the placebo in the human. And the concentration of serum aspartate aminotransferase (AST, GOT) and alanine aminotransferase (ALT, GPT), the indicator of liver cell damage, was lowered in those taking HPC, compared to those taking the placebo. In conclusion, taking HPC prior to drinking alcohol can somewhat reduce alcohol concentration in human blood and liver cell damage.

This experiment was conducted to determine the amount of asparagine content in soybean sprout soup as well as its effect on the regulation of blood alcohol concentration in human body. Asparagine content and alcohol concentration in blood were analyzed using the amino-acid analyzer and alcohol tester, respectively. Asparagine content in soybean sprout soup was highly significantly different among sprout soups sampled from different restaurants, although the boiling time and amount of sprout used were different among the samples. Significantly higher asparagine content was observed in soups with higher amounts of sprouts (2.81% in 500 grams of sprout) and 10 minutes after boiling with other solid ingredients in the soup. Lower concentration of alcohol in blood was recorded in persons with higher body weight. The asparagine+soybean extract (eaten immediately after drink) lowered the blood alcohol concentration significantly followed by only asparagine and control. The blood alcohol concentration after drinking become zero earlier (by 30 minutes), when asparagine+soybean extract or only asparagine was consumed as compared to control.

We have performed dispersion polymerization of acrylamide in tert-butyl alcohol/water mixture-using hydroxypropyl cellulose and ammonium persulfate as the stabilizer and the initiator, respectively - to study the effects that the concentration of monomer, initiator, and stabilizer, the tert-butyl alcohol/water ratios as polymerization media, and the reaction temperature have on, among other things, the polymerization kinetics, particle sizes, and molecular weights. The polymerization rate increased upon increasing the concentration of the monomer, initiator, and stabilizer, the water content in the tert-butyl alcohol/water media, and the polymerization temperature. The average particle size of the lattices increased upon increasing the concentration of initiator, the polymerization temperature, and the water content in the tert-butyl alcohol/water media, but it decreased upon increasing the concentration of monomer and stabilizer. The viscosity-average molecular weight increased upon increasing the concentration of monomer and stabilizer and the water content in the tert-butyl alcohol/water media, but it decreased upon increasing both the concentration of initiator and the polymerization temperature.

Chunggansan was tested for the effects on detoxication mechanism of alcohol. Chunggansan was treated firstly into samples, and then ethanol intoxicated animal models were set with them. The administration of Chunggansan to the rats increased proportionally in alcohol dehydrogenase activities in liver in relation to the level of concentration and days of treatment. Especially, the alcohol dehydrogenase was the most active when the concentration of extract was 200mg/kg and it was 7th day. The enzyme activities of alcohol dehydrogenase and aldehyde dehydrogenase in liver highly increased in Chunggansan pre-medicating group compared to that of ethanol treated group. Also, the blood ethanol concentration in rats was considerably decreased. In conclusion, Chunggansan recovers the damage of liver due to acute alcohol intoxication by the increased enzyme activities of alcohol dehydrogenase and aldehyde dehydrogenase.

Alcohol and acetaldehyde concentrations were measured in the blood and brain of rats which were treated with 20% alcohol (control group) or co-administered 20% alcohol with ginseng extract residue roasted (test group). There was no change in blood alcohol concentration between control and test group. However, the brain alcohol concentration was lowered in the test group which was treated for seven days. The concentration of aldehyde in the brain and blood was lowered in the test group. The activities of monoamine oxidase b in various regions of brain were recovered to normal group in the test groups. However, the Quantities of naloxone binding receptors were not changed by ginseng extract residue roasted.

The production results of the oriental functional beverage, which is aimed at reducing the alcohol concentration in blood, are as follows. Different kinds of herb medicine ingredients were combined to achieve the balance between Yin And Yang. They were grouped according to their respective characteristics and extracted by heat, Then they were combined and produced following the most effective mixture ratio. The drink produced by this way consisted mainly of water, Sugar, mineral, protein and fiber were partially contained. Among the minerals, the proportion of calcium, potassium, magnesium was high and iron was also contained. This drink turned out to be effective in reducing the alcohol concentration in blood within a very short time when it was taken once after drinking and taken aging 30 minutes later, which would double the dosage. This result shows that development of such a functional beverage using the herbal medicine, At the same time it will play an important part in reducing the alcohol concentrate in blood after drinking liquors.

The effects of alcohol concentration (30% 45% and 60%) on quality changes of maesil (Prunus mume) liqueur during leaching and ripening for 5 months were examined. Total acidity, pH and color of the liqueur generally increased with an increase alcohol concentration for 2 months. Thereafter the significant change did not occur. The contents of reducing sugar and polyphenol in the liqueur increased with an increase alcohol concentration and ripening periods. The major components of free sugar in maesil liqueur were fructose, glucose, sucrose and maltose. The content of fructose and glucose were higher than those of sucrose and maltose regardless alcohol concentration. Sucrose and maltose did not detect in the liqueur after leaching and ripening for 2 months. The major components of organic acid in maesil liqueur were citric, lactic, malic, and acetic acids. The optimal alcohol concentration was 45% and the duration of leaching and ripening was about 2 months for production of high-proof maesil liqueur.

This study was carried out for the purpose of improving the persimmon vinegar. Crushed persimmon(persimmon pulp) was used at alcohol fermentation using Saccharomyces bayanus for persimmon alcohol medium preparation. Glucose(8.39%) and fructose(7.96%) were the dominant free sugar in persimmon pulp before the at cohol fermentation. They decreased abruptly during alcohol fermentation and glucose was consumed more rapidly than fructose. Final alcohol concentration was finally reached to 8%(v/v) in 5 days for mentation of persimmon pulp. Pectinase pre-treatment of persimmon pulp resulted in tusker contents of galacturonic acid, galactose, methyl alcohol and isoamyl alcohol in main mash for alcohol fermentation than those in main mash prepared without pectinase pre-treatment. After alcohol fermentation tannin concentration was 350ppm and astringency was not perceived.

Aqueous mixtures of hyaluronic acid and poly(vinyl alcohol) system and hydrogels thereof were introduced to obtain new bioartificial materials that have excellent mechanical properties, biocompatibility and enhanced rheological properties. The interactions between hyaluronic acid and poly(vinyl alcohol) and/or borax were investigated by rheological measurements. Preparation parameters of the aqueous mixtures were mixture composition, the degree of hydrolysis of poly(vinyl alcohol) and borax concentration. From the rheological behavior, it could be deduced that the key factor of the interaction between hyaluronic acid and poly(vinyl alcohol) was the hydrogen bonding between them and the effect was pronounced with borax. Enhanced viscosity was observed at the composition of $20wt\%$ of hyaluronic acid solution and $80wt\%$ of poly(vinyl alcohol) and borax solution. Rheological properties were influenced by the degree of hydrolysis of poly(vinyl alcohol) and borax concentration. As the degree of hydrolysis and borax concentration increased, rheological properties increased due to the increased hydrogen bonding and networking of hyaluronate aggregates. Physical hydrogels from hyaluronic acid and poly(vinyl alcohol) were prepared and the composition dependence of the gels was rheologically investigated as well.
