        This study was conducted to demonstrate quality characteristics of ginger by making aged ginger( AG) with two methods, the frist method was that ginger was aged at constant temperature and humidity chamber for the duration of 10, 20 and 30 days, and the other method was drying the ginger just after steaming it for 3 hours. As the age was being processed, the volume of ginger’s appearance decreased rapidly and its color seemed to be darker because of the decrease in moisture. In the case of general components, the content of crude ash was depended on aged periods while the content of crude fat was independent with aged periods, and according to the content of crude protein, there was not any significant differences. The main valuable ingredient which is 6-gingerol showed the decreasing trend as it was exposed to heat with more time, and 6-shogaol which is also one of the main valuable ingredients showed high content at T-II(AG-10days). Free sugar and free amino acid of AG decreased as aged period goes by, and this study found that there were lots of essential amino acid (threonine, glutamic acid, alanine, valine, leucine and tyrosine) in ginger. The amount of unsaturated fatty acid of AG was significantly higher than the amount of saturated fatty acid of AG with the approximate ratio of 60:40, and the amount of free fatty acid of AG did not seem any big differences between AG and none AG. Considering both valuable ingredients and nutritive components, T-I (steamed ginger, SG) and T-II which was aged for 10 days were evaluated excellently.

        This study was designed to investigate foreigner preferences for the sensory characteristics of kimchi with different fermentation periods. After fermentation in a 5 freezer for 1, 7, and 15 days, Red Chinese Cabbage Kimchi, White Chinese Cabbage Kimchi, Kkakdugi, Chonggak Kimchi, Cucumber Kimchi, Green Onion Kimchi, and Mustard Kimchi were served to the respondents. The respondents had resided in Seoul and Kyunggi province for 3 years or less, and were from Asia, Europe, and the Middle East. Most respondents (62.9%) consumed a Korean meal daily, and 45% of all respondents reported eating kimchi 3 or 4 times a week. As a result, it can be said that foreigners residing in Korea preferred to eat kimchi as a side dish. Based on the respondents answers, we were able to determine the relative popularity of the different types of kimchi. They were, from most popular to least popular, Red Chinese Cabbage Kimchi, Kkakdugi Kimchi, Cucumber Kimchi, White Chinese Cabbage Kimchi, Chonggak Kimchi, Green Onion Kimchi, and Mustard Kimchi. Among those fermented for 1 day, Cucumber Kimchi was most preferred for its. When evaluating the overall preference of Kimchi, the best was in the order of Chinese cabbage (red)>Kkakdugi>Cucumber>Chinese cabbage (white)>Chonggak>Green onion>Mustard Kimchi. For 1 day in a fermented period, Cucumber Kimchi had the most preferred taste (5.76), appearance (5.66), odor (5.89), and texture (5.70). However, Cucumber Kimchi was least popular after 15 days of fermentation (p<0.01). The most preferred Kimchi after 15 days of fermentation was Red Chinese Cabbage Kimchi. Among the kimchi fermented for 7 days, White Chinese Cabbage Kimchi was most preferred. While foreigners indicated that they were satisfied with all the types of kimchi fermented for 1 day and 15 days, they were not satisfied with any of the kimchi fermented for 7 days, save for the White Chinese Cabbage Kimchi. Kkakdugi Kimchi had very high satisfaction scores for appearance, but low scores in taste. On the other hand, Chinese Cabbage Kimchi had low scores in odor (5.02-5.29), but high in texture (5.37-5.62) and taste (4.80-5.30), which are not factors sensitive to a change in acidity. These results showed that foreigners were generally satisfied with Kimchi, but became less satisfied as the Kimchi ripened. Most foreigners were not satisfied with the types of Kimchi that had a strong flavor. Chinese Cabbage Kimchi became the least sour after fermentation, and Cucumber Kimchi became most sour after fermentation.

        This paper analyzes phenolic compounds, carbon isotopes, and sugar components of whiskys based on the maturation period. For this, the paper considers a total of 40 whiskys(mainly imports) distributed in Korea. It is important to analyze the presence phenolic compounds(e.g., furfural, syringaldehyde, vanillin, syringic acid, and vanillic acid) because these are found only in whiskys ripened in oak. The results indicate that the total content of phenolic compounds increased with the increase in the storage period regardless of the type of whisky. In terms of vanillin/syringaldehyde(V/S), Scotch whiskys had 0.4~0.5; American whiskies, 0.30~0.34; and Canadian whiskies, 0.31~0.33. In terms of Scotch whiskys, Macallan had 0.25~0.34, making it unique among Scotch whiskys. In terms of the ratio of carbon isotopes, there were clear differences between malt Scotch whiskys, blended Scotch grain whiskys, American whiskys, and Canadian whiskys: -23.4~-24.3, -16.8~-21.0, -11.0~-11.5 and -9.5~13.9, respectively. In addition, malt Scotch whiskys contained 40~230 ㎎/ℓ of fructose; blended Scotch whiskys, 20~120 ㎎/ℓ; American whiskys, 50~70 ㎎/ℓ; and Canadian whiskys, 20~100 ㎎/ℓ, demonstrating that the fructose content of single-malt whiskys was twice the average fructose content. On the other hand, malt Scotch whiskys contained 30~170 ㎎/ℓ of glucose; blended Scotch whiskys, 20~120 ㎎/ℓ; American whiskys, 20~30 ㎎/ℓ; and Canadian whiskys, 10~110 ㎎/ℓ, demonstrating that the glucose content of single-malt whiskys exceeded the average glucose content. This study’s results can be used as a database of classification for whiskys based on the fermentation of raw ingredients and the period of maturation for distinguishing between different types of whiskys. In addition, the results can facilitate the verification of genuine whiskys by allowing for the identification of different types of whiskys based on the period of maturation.

        This study was carried out to investigate the effect of muscle part and aging period on free amino acids and aroma compounds of Hanwoo (Korean cattle) cow beef. The M. longissimus (ML) and M. semitendinosus (MS) from 101 mon-old-cows were aged at 2℃ for 14 d. The free amino acids concentration increased in both ML and MS on 14 d of aging. In ML, asparagine, glutamine, histidine, glycine, threonine, arginine, tyrosine, phenylalanine, isoleucine, leucine and lysine were significantly (p<0.05) higher than those in MS. Varieties of aldehydes, ketones, alcohols, hydrocarbons, nitrogen and sulfur compounds were detected in both ML and MS and majority of these compounds showed increasing trend on aging. The ML had higher 14 aldehydes (acetaldehyde, 2-methylpropanal, 3-methylbutanal, 2- methylbutanal, pentanal, hexanal, heptanal, E-2-heptanal, octanal, 2-octenal, 2-nonenal, E-2-decenal, E,E-2,4-decadienal and 2-undecenal), 5 ketones (2-propanone, 2,3-butanedione, 2-butanone, 2-heptanone and 2,3-octanedione), 4 alcohols (ethanol, 1-pentanol, 1-hexanol and 1-octanol), 3 hydrocarbons (3-ethyl-2-methyl-1,3-hexadiene, 3- methyldecane and 2,2-dimethyloctane) significantly (p<0.05) compared with MS. However, the MS had higher 5 nitrogen and sulfur compounds (methanethiol, dimethyldisulfide, fufural, 2,5-dimethylpyrazine and 2-octylfuran) significantly (p<0.05) compared with ML.

        This study analyzes flavor ingredients according to types of whisky and maturation periods based on total 40 different types of whisky that are mainly distributed to Korea via imports. Whisky was classified into four categories based on origin, and also into different categories based on maturity period, ingredients such as fusel alcohol, fatty acid, and fatty acid esters and proportion of patterns were analyzed. As a result of an analysis for fusel alcohol, high qualified types of alcohol including 3-methylbutanol, 2-methylbutanol, iso-butanol, and 1-propanol were detected from all Scotch whiskys, America whiskys, and Canadian whiskys. In particular, the proportional sum of 3-methylbutanol and 2-methylbutanol, and the sum of 3-methylbutanol and 2-methylbutanol/iso-butanol were regarded as core factors to determine each type of whisky. Acetaldehyde, ethyl acetate, and acetic acid increased as maturation and storage period became longer. As a result of the fatty acid and fatty acid ethyl ester analysis, the major fatty acids were dodecanoic acid and decanoic acid, both with detection of octanoic acid and hexanoic acid. However, dodecanoic acid, decanoic acid, and octanoic acid were lower than the detectable limit in American and Canadian whiskys, showing a unique phenomenon that hexanoic acid was detected only in very small amounts. Malt Scotch whisky showed higher significance than blended Scotch whisky, making it possible to classify types of whisky. Fatty acid ethyl ester contents showed significance with fatty acid either. In addition, changes in the whiskys based on maturation period were confirmed via proportions of fatty acids and fatty acid ethyl esters. In general, the proportion of fatty acids and fatty acid ethyl esters decreased as the storage period increased. This study provided basic data to classify types of whisky based on maturation periods by analyzing the proportion of flavor ingredients such as fusel alcohols, fatty acids, and fatty acid ethyl esters.

        This study examined the roles of autolytic enzymes and microorganisms in the ripening process of salted Alaska pollack tripe made with various concentrations of salt i.e, 7.5% and 20% by weight. Salted Alaska pollack tripe treated with antibiotic agents for the inhibition of microbial growth and a control were prepared experimentally, and changes in chemical composition and viable cell counts were investigated, individually, during the ripening process. Just after the preparation of the low salt Alaska pollack tripe made with 7.5% salt, viable bacterial cells occurred at a level of 10(5) CFU/g. In the control, bacterial counts increased rapidly to 10(7) CFU/g by the 14th day of ripening. However, in the sample treated with antibiotic agents, counts were decreased to a level of 10(4) CFU/g by the 3rd day of ripening and increased gradually to 10(6) CFU/g by the 5th day of ripening, and then the same value was maintained there-after. Just after the preparation of the high salt Alaska pollack tripe made with 20% salt, viable bacterial cells occurred at a level of 10(3) CFU/g. In both the samples treated with antibiotic agents and the control, bacterial counts decreased rapidly to 10°CFU/g by the 45th day of ripening and increased gradually there-after. The content of amino type nitrogen was 76.3 ㎎% just after the preparation of the low salt Alaska pollack tripe made with 7.5% salt. Amino type nitrogen content was increased to 283.5 ㎎% by the 5th day of proper ripening in the control, but it was increased to 208.0 ㎎% in the sample treated with antibiotic agents. The difference in amino type nitrogen content was 75.5 ㎎/100 g. The content of amino type nitrogen was 57.2 ㎎% just after the preparation of the high salt Alaska pollack tripe made with 20% salt. Amino type nitrogen content was increased to 198.3 ㎎ by the 60th day of proper ripening in the control, but it was increased to 162.0 ㎎% in the sample treated with the antibiotic agents. The difference in amino type nitrogen content was 36.3 ㎎/100 g. The contents of VBN and TMA-N were 102.1 ㎎% and 20.5 ㎎%, respectively, at the 7th day of ripening in the low salt Alaska pollack tripe made with 7.5% salt. The content of VBN was 60.0 ㎎% and TMA-N was not detected at the 21st day of ripening in the sample treated with antibiotic agents. The control sample was spoiled by the 7th day of ripening but the sample treated with antibiotic agents was not spoiled by the 21st day of ripening. On the other hand, VBN content was 37.2 ㎎% and TMA-N was not detected at the 90th day of ripening in the high salt Alaska pollack tripe made with 20% salt, and the control sample was not spoiled.

        Changes in major volatile odor components (VOC) and sensory properties of kimchi during ripening for 4 days were investigated, and major VOCs of the raw materials of kimchi were also analyzed. Seven of eight major VOCs of kimchi originated mainly from garlic, while one originated from ginger. During 4 days of kimchi ripening, the amount of ethanol, which was substantially higher than that of other VOCs, increased continuously but decreased slightly on the fourth day. The amount of diallyl disulfide decreased during ripening, while that of allyl mercaptan decreased on the first day and increased slightly thereafter. The amount of methyl allyl sulfide, diallyl sulfide, and methyl trisulfide increased continuously during ripening, while that of dimethyl disulfide and methyl propyl disulfide increased until the second day and decreased thereafter. Scores of overall acceptability, taste, and odor for kimchi ripened for 2 days were significantly higher than those of other samples (p<0.05). The correlation between scores of overall acceptability and the amount of dimethyl disulfide or methyl propyl disulfide was higher than that of other VOCs.

        Beef traceability, a system that provides all the records of beef production, helps customers purchase that they get to know detailed information of the Hanwoo beef. This study was carried out to investigate the DNA identity possibility in various cooking methods to ripen meat (soy sauce, gochujang sauce, 10% vinegar, 10% coke, 10% Cheongha, 10% Soju, raw, dried, and decayed) for beef traceability. The DNA content of decayed beef was higher than those of other cooking methods. It is thought that result of mixed pollutant, it did not affect amplified DNA allele height because of bovine specific microsatellite (MS) markers. The ripened sample in 10% vinegar 3 days was lowest a mount of extracted DNA (156 ng) and amplified DNA allele height (based on the raw samples to 38%) by MS markers compared with the other cooking methods. There are no significant correlation between amplified DNA allele height and the amount of extracted DNA. Therefore, beef DNA identity test in various cooking methods to ripen meat can used by bovine specific MS markers. Beef traceability system by DNA identify test will give more confidence in food safety to customers

        The study was done to change the morphology and pore size of SBA-15 silica, and the characteristics of SBA-15 silica were investigated with TG-DSC, XRD, SEM, TEM and N2 adsorption-desorption under changing aging conditions. SBA-15 silica having a 2D-hexagonal structure was synthesized and confirmed by SEM and TEM. The structure of mesoporus silica SBA-15 showed a pore having regularly formed hexagonal structure and a passage having a cylindrical shape. This result is in good agreement with the pore forming in XRD and cylindrical shape of the structure in N2 adsorption-desorption isotherm. SBA-15 silica showed a large BET surface area of 603-698 m2/g, a pore volume of 0.673-0.926 cm3/g, a large pore diameter of 5.62-7.42 nm, and a thick pore wall of 3.31-4.37 nm. This result shows that as the aging temperature increases, the BET surface area, pore volume, and pore diameter increase but the pore wall thickness decreases. The BET surface areas in SM-2 and SM-3 are as large as 698 m2/g. However, SM-2 has a large surface area and forms a thick pore wall, when the aging temperature is 100˚C and is synthesized into stable mesoporous SBA-15 silica.

        This study was conducted to aid in the development of the optimal recipe for chocolate with fermented and aged garlic extract (Allium sativum var. pekinense). We added garlic extract in order to increase the nutritional value of the chocolate. The optimal sensory composite recipe was determined, following Central Composites for chocolate with different levels of fermented and aged garlic extract (A) and cream (B), while analysis was performed by Response Surface Methodology, from the date that the sensory evaluation was performed. Ten experimental recipes, including 2 reference points in the composition, were selected. The compositional and functional properties were measured, and physical and sensory values were applied to the mathematical models. Perturbation plots showed the influence of each ingredient on the final product. Measurements showed significant values in lightness, sweetness, pH, hardness and cohesiveness, while sensory measurements showed significant values in color, texture, sourness, bitterness and overall quality. The optimum formulations were calculated by numerical and graphical methods, as being 34.61g fermented and aged garlic extract and 72.68g cream for each 200g chocolate. As well it was revealed that the aptitude of chocolate was more influenced by fermented garlic extract than it was by cream.

        This study was carried out to investigate the effects of various kinds of commercial salts, including sun-dried (Korea), purified, and traditional salts on the chemical and sensory properties and growth of microorganisms involved in kimchi fermentation. Kimchi was prepared by salting in 10% NaCl solution for 2 hours followed by addition of other spices and fermentation at 20℃. The decreases in pH suggested that kimchi fermentation can be classified into 3 steps: initial, intermediate, and final stages. In texture analysis, the hardness and fracturability of traditional salt kimchi were higher than those of regular kimchi. From the sensory evaluation test for kimchi, sensory scores were high for traditional salt addition, especially taste, overall preference and texture. Among various microorganisms related to kimchi fermentation, the growth of Leuconostoc mesenteroides, Lactobacillus plantarum, Pichia membranaefaciens and Escherichia coli were examined. Based on the conditions of kimchi fermentation, a 2% and 5% concentration of each salt were studied. Also, the conditions of the cultures at 37℃ were examined. There was no considerable difference in the growth of Leuconostoc mesenteroides, Lactobacillus plantarum, Escherichia coli in the different kinds of salts. However, the growth of Pichia membranaefaciens was strongly inhibited by a 5% concentration of traditional salt during incubation at 37℃.

        The effects of part of plum, alcohol content and addition of t-resveratrol on the formation of ethyl carbamate during the fermentation for wine were investigated at a time interval (45 days) for 6 months. The concentration of the ethyl carbamate in plum wine was determined according to KFDA guideline for ethyl carbamate analysis. In the plum wine with 16% or 30% alcohol content, the concentrations of ethyl carbamate were increased with time of fermentation periods. The maximum concentrations of ethyl carbamate in 16% and 30% plum wines after the fermentation for 6 months were 0.071 μg/g and 0.188 μg/g, respectively. When t-resveratrol was added at the level of 10 μg/g in both 16% and 30% plum wine, the concentrations of ethyl carbamate at 6 months were 0.078 and 0.216 μg/ g, respectively. The addition of t-resveratrol at the level of 300 μg/g in both 16% or 30% plum wine, the concentrations of ethyl carbamate at 6 months were 0.078 and 0.169 μg/g, respectively. The ethyl carbamate in the plum wine was not formed during fermentation for 6 month as using the flesh of plum, but 0.588 μg/g of ethyl carbamate was formed as using plum with plum seed. The addition of 300 μg/g of t-resveratrol actually increased the concentration of the ethyl carbamate by 0.088 μg/g as fermented for 6 months using plum with seed. These results suggest that the flesh of plum should be used to reduce the formation of ethylcarbamate for production of plum wine and that the addition of t-resveratrol during fermentation of plum wine can not reduce the concentration of the ethyl carbamate.

        This study was conducted to made a grid alloy (Pb-Ca-Sn-Al) which has a temporary composition ratio in order to improve the efficiency of lead acid batteries. The positive activity material made a 3BS(tri-basic lead sulfate; 3PbO·PbSO4·H2O) by a low temperature curing and it evaluates the plate efficiency through the life cycle testing. The initial current capacity of low temperature curing plate was excellent but the life cycle was not good (S1). As for the S2 plate, however, the initial current capacity and the life cycle were superior.

        This study was carried out to investigate the effects of addition of aged garlic extract (AGE) on the color and lipid oxidation of ground chicken during refrigerated storage. The leg meat from 6 weeks-broiler was chopped and added with 4% of distilled water (control) and AGE, respectively, and then stored at 4±0.2℃ for 8 days. The commercial garlic was aged for the relatively short time (40-90℃/300 hr →natural dryness/40 hr→20-30℃/30-50 hr). The pH value was not significantly different between control and AGE-added chicken. The TBARS level of chicken was remarkably inhibited by addition of AGE during storage. In CIE color values, AGE-added chicken showed lower L* and higher b*, C* and Ho values than those of control during storage. Therefore, the addition of AGE in ground chicken enhanced the lipid oxidative stability and change to dark color.
