Garlic (Allium sativum L.) and traditional herb has several functional properties and strong biological activities, making it useful as a functional food material. We investigated the antioxidant and anti-inflammatory activity of mixed compounds from red garlic and supplementary materials, including ginger (Zingiber officinale Roscoe), doraji (Platycodon grandiflorum), quince (Chaenomeles sinensis), citrus peel (Citri Pericarpium), and mint (Mentha arvensis). The extracts were prepared with water (W) and ethanol (E) at $70^{\circ}C$ (W-70, E-70) and $95^{\circ}C$ (W-95, E-95) for 3 h. The total content of phenolic compounds was the highest in E-70 (608.60 mg/100 g). Alliin, one of the active ingredients in red garlic, was contained at 1.18-1.29 mg/g and 0.81-0.85 mg/g in water and ethanol extract, respectively. Another active ingredient of red garlic, S-allyl-cysteine (SAC) had higher content in the water extract than in the ethanol extracts. DPPH radical scavenging activity was higher in E-70 (15.96-73.65%) at $313-5,000{\mu}g/mL$. ABTS radical scavenging activity was also higher in E-70 (5.71-77.19%) than in the others. The ROS production rate showed the same tendency as the NO production, with more efficacy in E-95. The expression level of iNOS and $IL-1{\beta}$ was decreased in the E-95 significantly at the concentration of $1,000{\mu}g/mL$ compared to the lipopolysaccharide (LPS) treated group. Based on the above results, the antioxidative and anti-inflammatory activities of the extracts of red garlic and supplementary materials were expressed by different useful substances. The contents of these useful substances were different according to the extraction solvent and temperature.

Ground fresh garlic and 50% ethanol garlic extracts were added into ground porks in order to investigate their effects on pH, peroxide and TBA values of ground porks during storage at 4$\^{C}$. The grounded porks tested were devided into two groups of fresh and heated forks at 100$\^{C}$ for 10 minutes. A significant control effect of ground garlic and extracts was found on peroxide and TBA values during storage, particularly for those added with 20% ground garlic and 10% garlic extracts. The effects were maximum after storage of 4-6 days and then decreased thereafter The pH was generally decreased until 6 days followed by the increase. Addition of garlic and garlic extracts caused a little increase in pH and the pH changes were less than the changes of control. Eventhough the effects of garlic on pH, peroxide and TBA values were similar for both heated and fresh pork, heat treated one showed more changes than fresh pork.

An attempt was made in this study to investigate the possibility of processing fresh garlic into an fresh garlic paste. The characteristics of fresh garlic paste and processing properties were investigated and the effect of salt, maltodextrin, acid and heat on product quality during storage were studied. After the processed fresh garlic paste was stored at 3$0^{\circ}C$ and 5$^{\circ}C$ without light for 6 months. The weight and pH of colve were 93% of total and 5.95, respectively. Addition of 10% salt, 10% maltodextrin, 01.% dl-malic acid, and heat on fresh garlic paste maintain color of fresh garlic could be preserved for 6 months at 5$^{\circ}C$. Judging from thiosulfinate and pyruvate content, and sensory evaluation, quality damage of fresh garlic paste which was make of 10% salt, 10% maltodextrin, 0.1% dl-malic acid, and heat on fresh garlic paste hardly occurred at 5$^{\circ}C$ but occurred considerable level at 3$0^{\circ}C$ during storage for 6 months.

Manufacturing method and ingredient ratio for young radish kimchi (yulmoo kimchi) and young radish watery kimchi (yulmoo mool-kimchi) were standardized from literatures. Ingredients having frequency of use greater than 50% were only used in the standardization process. Green onion, red pepper, red pepper powder, garlic, ginger, and anchovy juice were included in young radish kimchi. Green pepper, red pepper, garlic, ginger, and starch were included in young radish watery kimchi. The standardized ingredients ratio of young radish kimchi (yulmoo kimchi) on young radish 100 g was as follows: green onion 8.0$\pm$3.8, crushed garlic 2.9$\pm$1.3, crushed ginger 1.6$\pm$0.7, red pepper 7.0$\pm$1.7, red pepper powder 4.2$\pm$1.2, and anchovy juice 3.7$\pm$0.5. The standardized ingredients ratio of young radish watery kimchi (yulmoo mool-kimchi) on added water 100 mL was as follows: young radish 50.6:$\pm$10.8, crushed garlic 3.0$\pm$0.7, crushed ginger $1.5\pm$0, green onion 3.3$\pm$1.3, green pepper 3.3$\pm$1.9, red pepper 2.4$\pm$1.3, and starch $1.5\pm$0.6.

This study was carried out to evaluate the land suitability for southern-type garlic cultivation associated with both temperature and soil constraints. The suitability analysis was conducted with hourly temperature data from 2001 to 2010 at all fifty seven meteorological stations and the soil-based suitability map of garlic provided by Rural Development Administration. Firstly the temperature data were processed by the growth stages (germinating, bulbing, and winter vegetation season), and then were adopted to limit the irrelevant lands. Next, as a result of overlaying each soil and temperature suitability map, the total 274,339 ha of area was mapped as highly suitable or suitable for southern-type garlic cultivation and the top four of the largest classified si-guns were identified as Naju, Jeongeup, Gochang, and Jinju. On the other hand, the statistical records of KOSIS (KOrea Statistical Information Service) showed lower amount of cultivation area than the analyzed results in the major production sites, Goheung, Sinan, Haenam, and Muan. However, it should not be regarded as exceptional because farmer's preference might not correspond to potential land usability.

Effects of pH (1.8-10.2) and time (56 sec-15 min 4 sec) at high hydrostatic pressure (500 MPa) on the reduction of volatile compounds in garlic were studied. Volatile components of garlic were obtained from the headspace, analyzed, and identified by gas chromatography (GC)-mass spectrometry and an electronic nose. Nineteen sulfur compounds were identified as major compounds in garlic, and furan, aldehydes, alcohols, and ketones were also detected. Off-flavor compounds were more effectively reduced under strong acidic conditions. As the residence time at 500 MPa increased from 56 sec to 15 min 4 sec, the total amount of volatile compounds decreased significantly. The total amount of sulfur compounds decreased about 70% compared to those of raw garlic when the garlic was soaked in buffer (pH 6.0) and treated at 500 MPa for 15 min 4 sec. A principal component analysis showed that the off-flavors of garlic were reduced by the operating time of high hydrostatic pressure as well as pH treatment. The correlation coefficient of the results between GC and the electronic nose analysis was 0.9620. Therefore, pH and high hydrostatic pressure treatment could be used as an efficient method for reducing of garlic off-flavor.

White rot caused by Sclerotium cepivorum was reported to be severe soil-born disease on garlic. Disease progress of white rot of garlic (Allium sativum L.) was investigated during the growing season of 2009 to 2011 at Taean and Seosan areas. The white rot disease on bulb began to occur from late April and peaked in late May. The antifungal bacteria, Burkholderia pyrrocinia CAB08106-4 was tested in field bioassay for suppression of white rot disease. As a result of the nucleotide sequence of the gene 16S rRNA, CAB008106-4 strain used in this study has been identified as B. pyrrocinia. B. pyrrocinia CAB080106-4 isolate suppressed the white rot with 69.6% control efficacy in field test. These results suggested that B. pyrrocinia CAB08106-4 isolate could be an effective biological control agent against white rot of garlic.

This study was carried out to examine the mutagenicity of extracts from grilled pork belly and the effect of garlic on it by using Arnes test. And in order to imitate the in vivo metabolic activation system of the mutagens, the enzymatic activation system was adopted. The results are summarlized as follows: 1. The degree of browning in pork belly extracts increased with the increasing heating intensity of the grilling. 2. When pork belly grilled at "low" heating intensity, no mutagenicity was detected. However with the samples grilled at "medium" and "high" heating intersity, mutagenicity was recognized. 3. The mutagenicity of grilled pork belly extract decreased remarkabley with the addition of S-9 mix. 4. The mutagenicity of grilled pork belly extract decreased with the addition of garlic extract.
