The present study was conducted to investigate the effects of beverages containing fermented Akebia quinata extracts on alcoholic hangover. For this study, 25 healthy young men were recruited. All participants consumed 100 mL of water (placebo), commercial hangover beverage A or B, fermented A. quinata leaf (AQL) or fruit (AQF) extract before alcohol consumption. After 1 h, all participants consumed a bottle of Soju, Korean distilled liquor (360 mL), containing 20% alcohol. Blood was collected at 0 h, 1 h, 3 h, and 5 h after alcohol consumption. The plasma alanine transaminase (ALT) activity was highest in the placebo group. Compared with the control group, the AQL and AQF groups showed decreased ALT activity at 5 h after alcohol consumption. Plasma ethanol concentration was increased after alcohol intake and peaked at 3 h after alcohol consumption. Compared with the control group, the A group showed a higher plasma ethanol concentration at 1 h (P<0.05). At 3 h after alcohol consumption, the AQF group showed the lowest mean plasma ethanol concentration compared to the other groups; however, there were no statistical differences. After 5 h of alcohol consumption, the AQL and AQF groups showed lower plasma ethanol concentrations compared with the B group. The sensory evaluation score for the fermented A. quinata fruit extract was lower than for the commercial hangover beverages. In conclusion, the present intervention study results suggest that fermented A. quinata extracts alleviate alcoholic hangover and reduce plasma ethanol concentrations.

A study was conducted on three pollination methods on oriental melon(sageageol-ggul) grafting with pumpkin(seongjutozoa) for the labor-saving and to improve fruit set. Fruit weight, flesh thickness and fruit setting rate of oriental melon were greater in growth regulators treatment than those of pollinated by bees. Sugar content and hardness of fruits pollinated by bees were higher than those of by growth regulators. From the last ten days of the February to the first ten days of the March, fruit setting rate was $95\%$ in fruit setting growth regulators, whereas it was $46\%$ and $45\%$ in pollinated by honey and bumble bee, respectively. After the middle of March, the percentage of fruit setting was >$98\%$ in all the pollination methods. The cultivation under plastic houses of oriental melon, suitable fruiting time far the pollination by bees was decided after middle days of the March. Chromaticity and especially the value of 'a' of fruit of oriental melon pollinated by bees were higher than those of growth regulators. The percentage of fermented fruits of bee pollinated and growth regulators treated was $6.7\~9.1\%\;and\;28.1\%$, respectively. The weight of 100 seeds of bees pollinated were higher than that of growth regulators. The more increased the weight of 100 seeds the less appeared the rate of fermented fruits. The percentage of marketable fruits of the honey and bumble bee pollinated and that of growth regulators treated was $82\%,\;80.3\%\;and\;62.5\%$, respectively. The decreasing rate of fruit weight during storage of bees pollinated was less than those of growth regulators. In these results, the introduction of honey bee and bumble bee for the pollination of oriental melon was able to labor-saving of fruit set and increase of fruit quality.

Effects of interspace mulching between polyethylene film house on growth and quality of oriental melon were followed. Soil moisture in control was 26.0%. Those of black nonwoven fabrics sheet and black film were less 1.2% and 2.9% than control, respectively. Soil temperature in control plot was $2.4^{\circ}$ Those of black nonwoven fabrics sheet and black film were higher $0.8^{\circ}$ and $1.8^{\circ}$ than control, respectively. Black film was better than control in stem length, leaf number and area, chlorophyll content, xylem exudate, first flowering and fruit riping periods. Black film was better in fruit weight and soluble solid, and lesser in fermented and malformed fruit ratios, and increased 28% in marketable fruit ratio to control, 1,864kg. This results were mainly from vinyl coverage between polyethylene film house to intercept rainfall and to increase soil temperature, which fasted growth of roots after transplanting in winter season.

Objectives: This study was conducted to estimate the related health risk by investigating the content of biogenic amines (BAs) in commercial fermented alcoholic beverages. Methods: Ninety-seven samples, including takjus (34), fruit wines (26), distilled liquors (20) and beers (17) were purchased in Gangwon-do (Province) in 2019. The eight BAs (putrescine, cadaverine, spermine, spermidine, tyramine, β-phenylethylamine, histamine, and tryptamine) were analyzed by high performance liquid chromatograph (HPLC) after extraction (0.4 M HClO₄), pigment removal (carbon cartridge) and derivatization (1% dansylchloride). The health risk of exposure to BAs due to ingestion of commercial fermented alcoholic beverages was estimated as the margin of exposure (MOE). Results: Various BAs were detected in takju, fruit wine, distilled liquor and beer. Putrescine (not detected (ND)-12.60 mg/L), cadaverine (ND-5.45 mg/L), tyramine (ND-8.34 mg/L), β-phenylethylamine (ND-13.73 mg/L), histamine (ND-7.96 mg/L), and tryptamine (ND-19.00 mg/L) were found in takju. Putrescine (ND-15.34 mg/L), cadaverine (ND-7.90 mg/L), β-phenylethylamine (ND-3.06 mg/L), histamine (ND-9.68 mg/L), and tryptamine (ND-14.06 mg/L) were identified in fruit wine. Putrescine (less than limit of detection (

To raise the added value of the fruits of Cudrania tricuspidata, Cudrania tricuspidata vinegar was produced and examined for its fermentation conditions. Forty nine acetic acid bacteria with resistance against acetic acid, ethanol, and sulfide as high acetic acid producers were isolated from fermented foods and identified as Acetobacter indonesiensis, A. cerevisiae, A. orientalis, A. tropicalis, A. fabarum, A. pasteurianus, and A. syzygii based on the results of the analysis of the 16S rRNA gene sequences. Among them, two GRAS strains, A. pasteurianus SCMA5 and SCMA6, were finally selected for the production of acetic acid. Optimal vinegar productions were obtained from the medium containing 40% (v/v) fruit juice of Cudrania tricuspidata and 5% (v/v) ethanol at $25^{\circ}C$ for 72 hr. The sensory panel preferred the vinegar fermented with the SCMA06 to that with the SCM05 strain. The radical scavenger capacity of DPPH was 53% higher than that of the control in the vinegar fermented with the SCMA06 strain. The ${\alpha}$-glucosidase inhibitor activity as an index of the antidiabetic drug showed 91% inhibition, which is higher than that of acabose. This study will be helpful for the scale-up production of vinegar with the fruit of Cudrania tricuspidata.
