  • A group of 132 pre-school children with a mean age of six years and one month was the subjects of this investigation. These children were members of three nursery schools locating in Kwang-ju city. Each child's mother replied to a questionaire which included 42 food items and 4 questions. The results showed that the food preference of each child was variable and the group as a whole expressed more positive than negative feelings. The average number of foods liked per child was 22.9(range: $7{\sim}42$) among 42 food items. Peach, Apple, Strawberry, Laver, Egg, Tomato, Sweet Potato, Tangerine Orange and Beef were ranked in descending order of 'like' ratings. The average number of foods refused was 4.9 (range: $0{\sim}25$). Onion, Liver, Red Pepper Leaf, Root of Bellflower, Taro, Wild Seasame Leaf, Egg Plant, Cabbage, Water Cress and Bracken were ranked in descending order of 'refuse' ratings. The odor of hurting feelings, the hot taste and the flabby texture were the reasons why the children refused these foods. The average number of foods unexperienced was 4.4 (range: $0{\sim}14$). Kidney, Dried Small Whitebail, Tangle (DA SHI MA), Liver, SA RI Mushroom, Acorn Mook, Dried Fragrant Mushroom, Pine Agaric, Root of Bellflower and Ped Pepper Leaf were ranked in descending order of 'unexperience' ratings. Children's 'like' rating toward total foods was 57.3% and the 'refuse' rating was 11.7%. Among eight food groups, fruits showed the highest favority (91.4%) and mushroom showed the least (25.9%). The difference between male and female in the preference of total foods did not showed significant level. But the difference were significant in those of individual food groups; other vegetables, green and yellow leafy vegetables, mushrooms(above, p.<01), fishes and shellfish and sea weeds (above, p<.05). Children who had experienced meals missed rated 59.1% and 34.1% of these children missed meals once a week. The main reason for maels missed was due to the heavey snacks before meal time. Children who had snacks twice a day rated 45.6%. Main foods used as their snacks were starch foods (Cake, Biscuit, Sweet Potato) and citrous foods (Fruits, Apple, Tangerine).

  • Stone-cultural-properties, distributed In the area, have been investigated and studied on the characteristics and the rock phases in the geological and conservational point of view. Stone-Buddhas in the area can be subdivided into Maebul-, General -, and Massive rock-types according to their styles. The rocks used in these stone-cultural-properties are mainly massive, coarse grained biotite granite of the Jurassic age, which is widely distributed around the Reckon-gun area. However, quartz-feldspathic banded gneiss, marble, phyllite and hornblendite are also used. These rocks are mainly distributed in the Yongin-gun area. This suggests that the rocks used. These rocks are strongly influenced by chemical weathering so that the rock surface is very irregular with $2\~3mm$ relief. Biotite granite used shows generally weathered surface of brown color due to chemical weathering of feldspars. Moss are pervasive partly on the surface to show black and/or green colors. The strong weathering may induce secondarily to appear the igneous lineation, onion-structure, and/or minor cracks latent in the rocks. The cultural properties In the area are relatively well conserved except Maebuls and one(Duchangri 3-story) pagoda. However, one stone-buddha may be grinded recently by machine to take off the weathered surface resulting in the loss of its age and the original detailed shape. For conservation, they must be scientifically considered on the shape, kind of the rock phase and characteristics of the weathered phenomena.

  • In an effort to determine the effect of ingredients on the sensory characteristics of dongchimi, 10 different samples of dongchimi were prepared in various combinations of 4 ingredients most notably red pepper, garlic, ginger, and green onion and their physicochemical, microbiological, and sensory characteristics were assessed. Each ingredient utilized for the preparation of dongchimi did not affect changes in pH and titratable acidity, but exerted significant effects on sensory scores of overall acceptability, acid odor, salty, and hot taste. In cluster analysis using the 'Ward' method, dongchimi samples were classified into three groups. The first group was the samples prepared with a variety of ingredients including garlic, and the second group included samples prepared with the sole ingredient, except for red pepper. The third group had features similar to those of the sample prepared without other ingredients. It was determined that garlic played a crucial role in the sensory properties of dongchimi, and the addition of various ingredients enhanced hot taste and reduced acid odor, sourness, moldy odor, and carbonated taste by their interaction.

  • This study was intended to suggest HACCP-based standard recipe for bellflower roots, classified as no thermal cooking process, served in a university foodservice operation. The time-temperature and microbial contamination level in each cooking step were analyzed. The temperatures of bellflower root, peeled garlic and green onion at receiving were at 13.8$\pm$2.8, 12.6$\pm$2.9 and 13.7$\pm$$0.8^\circC$ respectively, which were above the temperature limit. The time consumed for pre-preparation was up to 90 min at room temperature having high microbial growth potential. The levels of total plate counts (TPC) of bellflower root and garlic were over the limit of $10^6$ CFU/g as were the numbers of coliforms in bellflower roots. There were no microbial reductions in pre-preparation and cooking, which resulted in over $10^5$- $10^6$ CFU/g of TPC at service step. Two CCPs identified were washing/sanitation at pre-preparation and service steps. The control measures were washing/sanitation and temperature control. It was verified that CCPs for no cooking process developed in preceding studies were applicable for the microbiological food safety of this menu item. The HACCP-based standard recipe was developed to produce a quantity for 100 servings by observing the critical limits established for CCPs. These results suggest that the selection of proper provider is imperative to control the microbial contamination of raw materials at purchasing step. Also, the sanitary education program should be developed for the employees to understand and comply the HACCP plan and standard recipe.

  • This principal objective of this study was to evaluate the sensory properties and flavor compounds of Kimchi prepared with different levels (0.0%, 0.4%, 0.8%, and 1.2%) of Backryeoncho extracts (BE). At high levels of BE, Kimchi showed increased level of crispness and flavor, and also jeotgal odor decreased in the sensory evaluation. Addition of 0.8 % BE resulted in the highest scores for color, taste, and overall acceptance of Kimchi. Therefore, addition of 0.8 % BE appears to be an acceptable approach to enhance the quality of Kimchi without reducing acceptability. As a result of flavor compound analysis, a total of 24 volatile flavor compound, including 11 S-containing compounds, 6 terpenes, 1 acid, 1 ester, 1 alcohol, 2 miscellaneous compounds, 2 thiocyanates, etc., were detected by GC/MS. The major volatile compounds were s-containing compounds and terpene hydrocarbon, and especially terpene of sabinene was newly detected in Kimchi with added BE. Levels of 2-vinyl-[4H]-1,3-dithin derived from garlic flavor as a sulfide-containing compound along with diallyl trisulfide derived from green onion flavor were reduced in Kimchi with added 0.8% BE. Most sulfide-containing compounds were reduced in Kimchi with added BE, whereas most terpenes detected in control Kimchi were not detected.

  • The purpose of this study was to investigate the knowledge and perception for Kimchi in middle school students. A questionnaire was used as the instrument of investigation. The subjects were 375 male students and 278 female students in Masan and Changwon City. The main results of this study are as follows. Ninety-three point three percent of the subjects were nuclear family type and 61.7% of respondent's mother had job. The average knowledge score for Kimchi of the subjects was 5.27 out of possible 10 points and the average value score on Kimchi was 41.25 out of 50 points. Eighty-six point one percent of students think they should eat Kimchi because Kimchi is good for the health(38.6%) and Kimchi is our traditional food(31.4%), and it was significantly difference between gender(p<0.01), male students more realized 'Kimchi is good for the health(41.6%)', whereas female students more realized 'Kimchi is our traditional food(38.9%)'. The subjects perceived that the additive material making for Kimchi were powdered red pepper(80.2%), garlic(62.5%), salt(62.0%), salted, fermented shrimp(50.2%). ginger(49.5%), green onion(39.8%), salted, fermented anchovy(34.9%), sesame(25.0%), carrot(22.4%). More than 70% of the subjects estimated for Kimchi 'Kimchi is our traditional food(84.1%)', 'Kimchi must be developed the international food'(73.7%), 'Kimchi must be in succession(75.8%)', 'Kimchi is very nutritious food(70.3%)'. However, they thought Kimchi have to be improved more hygienically(38.8%) and less stimulative taste(25.7%). The knowledge for Kimchi showed a positive correlation with the value on Kimchi and the preferences for Kimchi, and the value on Kimchi was a positively related to the preferences for Kimchi(p<0.01). Therefore it is need to the development of program for the knowledge for Kimchi and the value on Kimchi in order to improvement the preferences for Kimchi.

  • The consistant appearance of coliforms in fermenting kimchi was examined and measures of removing coliforms early in the fermentation were investigated. Allyl isothiocyanate $({\geq}50\;ppm)$, horseradish powder $({\geq}0.4%)$, and garlic juice $({\geq}2.0%)$ were effective in removal of coliforms early in kimchi fermentation. However, mustard powder and methyl methanethiosulfonate were not effective. Nisin, known as a promising agent for the prevention of kimchi over-acidification, allowed coliforms to survive in kimchi longer with only marginal extention of edible period. Individual kimchi ingredients such as Chinese cabbage, garlic, red pepper powder, ginger and green onion were all found to contain coliforms. Coliforms were not detected from garlics sold unpeeled and commercially prepared red pepper powder.

  • Fermentative and antioxidative characteristics of red mustard leaf (RML) kimchi, a traditional, fermented Korean vegetable food, were investigated. For the study, RML kimchi was made of RML, with green onion, red pepper, garlic, ginger, and sugar, and fermented at 15$^{\circ}C$. The pH was decreased and total acidity was increased during fermentation. The contents of reducing sugar, total vitamin C, and total Phenol content were 2.36%, 65 mg%, and 59 mg% at the initial stage. Although the content of reducing sugar decreased gradually during fermentation, however, the quantity of ascorbic acid decreased with the tendency of slightly increased at 6 days, and the amount of total phenol was increased. CIE L*, a*, b*values were increased until 6 days of the fermentation. In order to determine the antioxidative activity of RML kimchi itself, the model systems of RML kimchi were made with cooked beef. TBA values of RML kimchi which was fermented for 6 days showed the lowest level in model systems. Water, n-hexane, methanol extracts of RML kimchi had a considerable antioxidative activity with the inhibition of formation of peroxide during the autoxidation of linoleic acid mixtures in aqueous model systems.

  • Four bacteria producing viscous exopolysaccharides (EPSs) were isolated from Korean fermented vegetables (Cucumber kimchi, Young radish kimchi, Green onion kimchi) using a selection medium intended for isolating bacteria with tannin-degrading activity. They were identified phylogenetically by 16S rDNA sequence analysis and found to be very close to Enterobacter cowan ii, Escherichia senegalensis, Enterobacter asburiae, and Enterobacter ludwigii. Strain CK31, the most efficient EPS-producer, produced a heteropolysaccharide with an approximate molecular weight of 420 kDa. The neutral sugar fraction of the EPS was composed of rhamnose, fucose, arabinose, mannose, galactose, and glucose.

  • Effects of kimchi and its ingredients, vitamin C and $\beta$-sitosterol on the growth of Helicobacter pylori were investigated. Three kimchi variations were studied: a standard recipe (kimchi I) and two functional variations for cancer prevention and treatment made with organically grown ingredients (kimch II and III). Methanol extracts and juices from kimchi I and III did not inhibit the growth of H. pylori. However, 10 mm and 12 mm inhibition zones were formed by methanol extract and juice from kimchi II, which had higher concentrations of red pepper powder (RPP) than those of kimchi I and III. Among the major kimchi ingredients, methanol extracts of RPP, garlic and ginger substantially inhibited the growth of H. pylori. The maximal inhibition zone (30 mm) was attained with garlic treatment. Inhibitory effects of the RPP, garlic and the sub-ingredient mixture (prepared with radish, garlic, RPP, ginger, green onion, sugar and fermented anchovy juice) on H. pylori were decreased by lactic acid bacteria fermentation. Neither the fermented garlic nor the fermented sub-ingredient mixture inhibited the growth of H. pylori. But, the inhibition Bone of fermented RPP was 12 mm, which was less than the 16 mm inhibition zone formed by the non-fermented RPP. Vitamin C and $\beta$-sitosterol which are known to be functional active compounds of kimchi also showed no inhibitory effect on the growth of H. pylori after 3 days of incubation. Further study is needed to determine why the inhibitory effect is removed or decreased by lactic acid fermentation, and to determine if fresh kimchi and lactic acid bacteria of kimchi can inhibit the growth of H. pylori.
