This study was conducted to compare the quality of Korean and imported wine through sensory evaluation and to determined the harmony between wine and foods. The physiochemical characteristics, such as the sugar content, total acidity, pH and color values of Korean and imported wine were also measured. Three white wines made in Korean (WWK), Germany (WWG) and U.S.A (WWU), and three red wines made in Korean (RWK), France (RWF) and Chile (RWC), were used for testing. In the result of sensory evaluation, the white wine made in Germany (WWG) was the most preferred in flavor, taste and overall preference, and the red wine made in France (RWF) was the most preferred in appearance, flavor, taste and overall preference. The overall preference of wine was positively correlated with the total balance in the white wine (r=0.66) and in red wine (r=0.81). In regards to the harmony of wines with foods, the white wine made in Korean (WWK) was suitable for sirloin steak, the WWG for codfish steak and salad and the white wine made in the U.S.A (WWU) for sandwiches. The red wine made in Korean (RWK) was significantly harmonious with salad, the France red wine (RWF) with sirloin steak and in the red wine made in Chile (RWC) with sandwiches. The L and b-values of white wine were the highest in WWG. the L-values of red wine were the highest in RWK, and the a-values of red wine were the highest in RWC and RWF. The WWU was the highest in sugar content among the white wines $10.83^{\circ}$ Brix and the RWC ($8.32^{\circ}$ Brix) was the highest among the red wines. Total acidity was higher in WWU (0.8) and in RWF (0.45) and thy pH values were the highest in WWK (2.82) and RWK (3.35).

The aim of this research was to evaluate the effects of red wine on the quality characteristics of sauteing chilli sauce shrimp. Cooked chili sauce shrimp was storaged on $3^{\circ}C$ fot 15 days. The TPC of sauteing chili sauce shrimp with red wine was increased for all experimental groups with a longer storage period and the groups with 10% or 20% red wine had lower TPCs than control. The AV and TBA were increased for all experimental groups with increased holding time, but in case of 20% red wine had lower value for AV and TBA than control and 10% red wine. In a sensory evaluation, the 10% red wine group was highly evaluated compared to control and 20% red wine group. In conclusion, we can find out that 10% red wine group was most pertinent to antimicrobial effect, antioxidant effect and sensory quality.

To develop a ginseng wine, the brewing conditions and sensory evalution of the wine were studied. The ginseng, ginseng marc and red ginseng marc can be made into wine by ethanol fermentation with Saccharomyces cerevisae. The results showed that the higher ginseng concentration was, the faster the brewing velocity became. The ginseng marc wine brewed with 10% ginseng marc and 25% sugar was a great favorite The results from the mixture of ginseng and ginseng marc revealed that the mute the content of ginseng was, the faster the velocity of brewing became. It took 27 days for a wine from 10% ginseng marc to be brewed Into 12% ethanol, 10% ginseng took 10days and red ginseng took 15 days. Among these, a wine from 10% ginseng was superior to others in flavor, color and taste. And the wine from 6.7% red ginseng was favorite. Contents of the favorite wine from ginseng marc were 80mg/ml of reducing sugar, 2.6 of acidity, 12% of ethanol, 28mg/ml of saponin, and it's pH was 3.5.

Abilities of Korean black raspberry (KBR) wine to induce differentiation of 3T3 L1 adipocytes and express HepG2 cardiovascular disease-related genes were determined and compared with those of red wine. Red wine attenuated the differentiation of adipocytes faster than KBR wine and control. KBR wine decreased cholesterol concentration in HepG2 cells at a similar level to that of red wine, resulting in similar degrees of suppression in apolipoprotein B100, and enhancement in LDL receptor and 3-hydroxy-3-methylglutaryl coenzyme A reductase mRNA levels.

A Vitis hybrid-Vitis coignetiae red wine was vinified by fermentation of a mixture of a Vitis hybrid.Vitis coignetiae must with Saccharomyces cerevisiae KCTC 7904 at $25^{\circ}C$ for 10 days. The Vitis hybrid-Vitis coignetiae red wine showed high antihypertensive angiotensin I-converting enzyme (ACE) inhibitory activity (67.8%) and antioxidant activity (76.7%). The antihypertensive ACE inhibitor in the Vitis hybrid-Vitis coignetiae red wine was partially purified by solid phase extraction chromatography, and its ACE inhibitory activity yielded an $IC_{50}$ of 1.8 mg/mL. Six kinds of oligopeptides, including five new kinds, were contained in the partially purified ACE inhibitor fraction from the red wine after 10 days of fermentation. Antioxidant activity decreased significantly from 76.7% to 40.5% when the post-fermentation period was prolonged to 30 days.

The wine industry requires practical methods for objectively measuring the composition of both red wine grapes on the vine to determine optimal harvest time; and of freshly harvested grapes for efficient allocation to vinery process streams for particular red wine products, and to determine payment of contract grapegrowers. To be practical for industry application these methods must be rapid, inexpensive and accurate. In most cases this restricts the analyses available to measurement of TSS (total soluble solids, predominantly sugars) by refractometry and pH by electropotentiometry. These two parameters, however, do not provide a comprehensive compositional characterization for the purpose of winemaking. The concentration of anthocyanin pigment in red wine grapes is an accepted indicator of potential wine quality and price. However, routine analysis for total anthocyanins is not considered as a practical option by the wider wine industry because of the high cost and slow turnaround time of this multi-step wet chemical laboratory analysis. Recent work by this ${group}^{l,2}$ has established the capability of near infrared (NIR) spectroscopy to provide rapid, accurate and simultaneous measurement of total anthocyanins, TSS and pH in red wine grapes. The analyses may be carried out equally well using either research grade scanning spectrometers or much simpler reduced spectral range portable diode-array based instrumentation. We have recently expanded on this work by collecting thousands of red wine grape samples in Australia. The sample set spans two vintages (1999 and 2000), five distinct geographical winegrowing regions and three main red wine grape varieties used in Australia (Cabernet Sauvignon, Shiraz and Merlot). Homogenized grape samples were scanned in diffuse reflectance mode on a FOSE NIR Systems6500 spectrometer and subject to laboratory analysis by the traditional methods for total anthocyanins, TSS and pH. We report here an analysis of the correlations between the NIR spectra and the laboratory data using standard chemometric algorithms within The Unscrambler software package. In particular, various subsets of the total data set are considered in turn to elucidate the effects of vintage, geographical area and grape variety on the measurement of grape composition by NIR spectroscopy. The relative ability of discrete calibrations to predict within and across these differences is considered. The results are then used to propose an optimal calibration strategy for red wine grape analysis.

Alcohol fermentation conditions for the production of plum wine were investigated and further, sensory evaluation and physiological functionalities of the plum wines were also determined and compared with those of plum liquors made by soaking plums in a mixture of commercial soju and 10% sugar for 15, 30, 60 and 120 days. Ethanol was produced maximally when 5% Saccharomyces cerevisiae was added to red plum juices and fermented at 25$^{\circ}C$ for 5 days. Angiotensin-converting enzyme inhibitory activity and fibrinolytic activity of the red plum wine were better than those of the plum liquors. However, the antioxidant activity, the SOD-like activity and the tyrosinase inhibitory activity of the plum liquors were better than those of the red plum wine. On comparing the red plum wine and the various kinds of plum liquors, the red plum wine was shown to be more acceptable by sensory evaluation.

The antioxidant activities of aroma extracts from commercially available red wines in Korea were evaluated. The aroma extracts of the red wines were extracted by simultaneous steam distillation. Antioxidant activity was measured by DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity and ABTS (2,2-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid) radical cation scavenging activity. DPPH radical scavenging activity of the aroma extracts in the red wines increased with increases in the amount of wine used for aroma extraction. Antioxidant activities of domestic wine 1, imported wine 7, and imported wine 12 were 97.16, 96.72 and 94.52%/20 mL wine by DPPH assay and 7.09, 8.07 and 7.28 mg ascorbic acid equivalents per mL wine by ABTS assay, respectively. This study demonstrates potent antioxidant activities of the aroma extracts of commercially available red wines in Korea.
