        This study was carried out to investigate the effects of various kinds of commercial salts, including Hanju salt, Deep sea water salt, Salicornia herbacea salt, Guwoon salt, Bamboo salt and salt replacement for the reduction of Na concentration in kimchi. The fermentative characteristics of these salts were determined during the fermentation at 10℃. Kimchi using a salt replacement and with Salicornia herbacea salt showed slow changes in their pH values. The use of salt replacement showed the lowest level(0.97%) of the retardation of kimchi fermentation. For the preparation of kimchi that used a low Na, chemical and microbial changes were investigated during the fermentation of process, examining preparations with both table salt and a salt replacement(CS-17). The salinity level of kimchi prepared with table salt(control) and the salt replacement (CS-17) were 2.17~2.5% and 1.72~1.99% during fermentation, respectively. The Na contents of kimchi with CS-17(562.5 ㎎%) showed a lower level than that with table salt(879.0 ㎎%). The growth of Leuconostoc sp. was highest (1.5×108 cfu/g) in Kimchi with CS-17 at 6 day-fermentation, but the highest level(2.3×107 cfu/g) in kimchi with table salt was at 7day- fermentation. The cells of Lactobacillus sp. in the kimchi prepared with CS-17 and table salt increased to 3.0×108 cfu/g and 6.0×107 cfu/g at 8day-fermentation, respectively. It was concluded that the use of CS-17 could reduce Na levels in kimchi and mitigate over-maturation.

        Ohmic heating uses electric resistance heat which occurs equally and rapidly inside food when an electrical current is passed throught. In this study, we observed the physical & chemical characteristics changes which occurs in soybean protein during heating denaturation by using ohmic and conventional heating. After the ohmic heating process, we could not find any change of the primary protein structure in the denaturated soy protein samples. However, the rate of imbibed water(RIW) of the ohmic samples was 2 times faster than that of the conventional samples. Also the ANS-surface hydrophobicity was decreased, which is very closely related to RIW. In the differential scanning calorimeter(DSC) analysis result, all 7S soyprotein fraction samples were completely denaturated by ohmic and conventional heating. However, the 11S samples were completely denatured only by ohmic heating. According to the DSC result, we decided that soyprotein was damaged by temperature and electrical current during ohmic heating. The damage of electrical current was a cause of the charcteristic changes.

        Differences in sensory evaluation, physicochemical properties and antioxidant activities between green tea concentrations and tannase-treated green tea concentrations were measured in this study. The results showed that pH did not differ dependent on tannase treatment but antioxidant ability were slightly increased through tannase treatment without significant (p<0.05). However, the turbidity of the tannase-treated green tea concentration had significant difference to the non-treated concentration. The astringency, tested via sensory evaluation, decreased significantly after tannase treatment(p<0.05). Traces of epicatechin gallate(ECG) and epigallocatechin gallate(EGCG) also disappeared after the tannase treatment, due to the fact that the ester linkages in the catechin structure were broken by the tannase. It was concluded that tannase treatment of tea products is a very effective process for decreasing astringency and turbidity.

        The antioxidant activities of the ethanol extract of Arctium lappa were assessed by measuring the 1, 1-diphenyl-2-picryl- hydrazyl(DPPH) radical scavenging effect, inhibition of Fe2+-induced lipid peroxidation, inhibition of malondialdehyde(MDA)- bovine serum albumin(BSA) conjugation reaction and antimutagenic capacities using the Ames test. The DPPH radical scavenging activity and inhibition of Fe2+-induced lipid peroxidation of the Arctium lappa ethanol extract significantly increased in a dose-dependent manner. In the radical scavenging assay using DPPH, the IC50 of the Arctium lappa extract was 296 ㎍/assay(1.29 ㎎ of dry sample). In addition, the IC50 in the inhibition of Fe2+-induced lipid peroxidation was 1, 759 ㎍/assay(7.65 ㎎ of dry sample). This extract also significantly inhibited the MDA-BSA conjugation reaction with an IC50 of 57.58 ㎎/assay(250 ㎎ of dry sample). However, no inhibitory effects against the direct and indirect mutagenicities in Salmonella Typhimurium TA98 and TA100 were observed. Based on these results, the ethanol extract of Arctium lappa was shown to display considerable antioxidative activities.

        The purpose of this study was to assess dietary variety by food habits(regularity of meal time, regularity of repast, repast of breakfast, lunch, and supper, number of suppers and night snacks per week, and duration of meal) in 138 female university students residing in Bucheon and its adjacent area. Food habits were assessed via a self reporting questionnaire, and a 3-day dietary recall survey was conducted by interviewing. Dietary variety was assessed by dietary diversity score(DDS), meal balance score(MBS), and dietary variety score(DVS). The average DDS, MBS, and DVS were 3.87±0.57, 7.27±1.48, and 12.59±3.14, respectively. The DDS(2.21±0.83) of the breakfast in the group in which the regularity of meal time per week was 5~7 days was significantly higher(p<0.01) than the DDS(1.47±0.96) of the breakfast in the group in which the regularity of meal time per week was ≤2 days. The MBS(6.69±1.43) of the group in which the regularity of meal times per week was ≤2 days was significantly lower(p<0.01) than the MBS of the group in which the regularity of meal time per week was ≥3 days. The DDS(2.38±0.69) of the breakfast in the breakfast over eating group was significantly higher(p<0.001) than the DDS(1.83±0.83) of breakfast under eating group. The MBS(6.56±1.46) in the breakfast skipping group was significantly lower(p<0.01) than the MBS(about 7.6) in other breakfast eating groups, and the DVS (13.79±3.21) in the breakfast over eating group was significantly higher(p<0.05) than the DVS(11.53±2.94) in the breakfast skipping group. The DDS of breakfast, lunch, and snack were not significantly correlated with the number of suppers per week, but the DDS(2.65±0.52) of the supper in the group in which the number of suppers per week was 7 was significantly higher(p<0.05) than the DDS(2.22±0.49, 2.25±0.62) of the supper in the group in which the number of suppers per week was ≤2, 3~4. The DDS, MBS and DVS were not significantly correlated with the number of suppers per week. The DDS(1.33±1.25) of the breakfast in the group in which the number of night snacks per week was 6~7 was significantly lower(p<0.05) than the DDS of the breakfast in the group in which the number of night snacks was ≤5. Also, the DDS(4.42±0.32) per day in the group in which the duration of meal was <10 min. was significantly higher(p<0.01) than the DDS(3.51±0.53) per day in the group in which the duration of meal was ≥30 min. These findings suggest that nutritional education based on female university students` eating variety and food habits(regularity of meal time, regularity of repast, repast of breakfast, lunch, and supper, number of suppers, and night snacks per week, and duration of meal) may be required to improve dietary variety.

        Wet noodles with different percentages of amaranth powder were prepared and their cooking characteristics were evaluated. The cooking quality, mechanical textural properties, and a sensory evaluation was conducted with the prepared noodles. Cooked noodle properties, weight, and volume decreased as amaranth content of the wheat flour increased, whereas turbidity and water absorption of the soup increased, except for cooked noodles with 30% amaranth. The L-value of the raw and cooked noodles decreased significantly with increasing amaranth powder content. The a- and b-values increased with increasing amounts of added amaranth powder. The L-value of the raw and cooked noodles with amaranth was significantly lower than that of the control, and the a-value was lower than that of the control, whereas the b-value was higher than that of the control for both raw and cooked noodles. A texture profile analysis of the raw noodles showed significantly higher levels of hardness, cohesiveness, gumminess, chewiness, and springiness in the amaranth noodles compared to those in the control; the values for adhesiveness were not significantly different. The hardness, gumminess, springiness, and chewiness of the cooked noodles decreased in proportion to the quantity of added amaranth. The springiness, adhesiveness, and cohesiveness of cooked noodles with amaranth decreased slightly. Overall, the results of a sensory evaluation revealed that the cooked noodles with amaranth had higher values than those of the control, except for overall acceptability. Amaranth added at a concentration of up to 30% increased brown color and the peculiar amaranth odor. In a sensory evaluation, cooked noodles with 20% amaranth powder were preferred more than the other noodles for overall acceptability.

        In this study, we made Sulgidduk with commercialized dried nonglutinous rice flour and different levels of soybean curd. For physical properties of the bean curd-Sulgidduk, its water content was increased significantly with a growing addition of soybean curd. In chromaticity, its L value(brightness) and a value(redness) were decreased significantly with more bean curd while b value(yellowness) went up in Sulgidduk with a large amount of rice flour but went down significantly in the Sulgidduk with a small amount of it. Its hardness of texture was found to be the highest in the Sulgidduk with the most dried nonglutinous rice flour and it tended to be higher with more rice flour and less soybean curd. For cohesiveness, it was recorded to be the highest in the Sulgidduk without soybean curd and showed a tendency of decreasing by adding the bean curd but increased later significantly. In addition, its springiness and brittleness became larger with addition of more dried nonglutinous rice flour. From these results, the best ratio of the bean curd-Sulgidduk to increase nutrition and absorption and to satisfy physical and sensory properties, was 420 g to 500 g of soybean curd to dried nonglutinous rice flour. Moreover, it was considered to decline the calorie of Sulgidduk by adding soybean curd as a material and to contribute to its commercialization by extending storage and preservation time of soybean curd with a short expiration date.

        The purpose of this study was to investigate foodservice management practices in the child care centers and kindergartens. Interviews were held from May to July 2008 to understand the current situation concerning foodservices in Seoul and Gyeonggi provinces. Surveys were sent out from August 2008 to April 2009 to 1, 478 child care centers and 299 kindergartens via the postal service. Among them, 203 child care centers(13.7%) and 64 kindergartens(21.4%) responded. One of the largest concerns while preparing the food was nutrition(68.7%, 69.8%, respectively) followed by sanitation(24.4%, 27.0%, respectively). The most frequently referred sources for planning the menu were the Seoul child care information center(55.4%) for child care centers and kindergarten related internet sites(39.0%) for the kindergartens. In general, the child care center principal was in charge of planning the menu(40.1%). Child care centers and kindergartens purchased ingredients mostly from large retailers(55.3% and 44.7%, respectively), whereas 46.0% and 56.3% of those did through foodservice suppliers. Dietitians were rarely employed at these facilities, and this may cause unprofessional foodservice management.

        This study was performed to assess the relationships among bone mineral density, anthropometric measurements, maternal factors and exercise in premenopausal and postmenopausal women. Anthropometric measurements were taken by a trained practitioner and the maternal factors of the 78 subjects in Gyeonggi-do were acquired by an interview questionnare. The BMD of the lumbar spine(L2~L4), femoral neck, Ward`s triangles and trochanters were measured by dual energy X-ray absorptiometry. The mean age of the premenopausal women was 45.23 years and that of the postmenopausal women whose ase of menopause was 49.37 years was 61.27 years. The age, waist and waist to hip ratio of postmenopausal women were significantly higher than those of premenopausal women. BMD of the lumbar spine(L2~L4) in postmenopausal women was significantly higher than that of premenopausal women. Number of children and age at last delivery were significantly higher in postmenopausal women than those in premenopausal women. The BMDs of the lumbar spine and femoral neck of premenopausal women was positively correlated with weight, body mass index, waist and WHR and the BMDs of these two sites in postmenopausal women were positively correlated with height, and weight. In postmenopausal women, BMD of the lumbar spine was negatively correlated with duration time after menopause and BMD of the femoral neck was positively correlated with age at last delivery. These results suggest that it is necessary to maintain adequate body weight. Health management and education about performing more exercise are recommended for postmenopausal women to prevent osteoporosis.

        This study was performed to investigate the effect of rice bran dietary fiber powder on serum lipid levels, bowel function, and mineral absorption in rats. Four weeks old male Sprague Dawley rats(SD rat) were divided into four groups : control group fed 5% cellulose as a fiber source, RB10 fed 5% of cellulose and 10% of rice bran dietary fiber powder, RB20 and RB30. The animals were fed the experimental diets for 4 weeks. Serum lipid levels were not significantly different among the groups. But, fecal total cholesterol(TC), triglycerides(TG), and high density lipoprotein cholesterol(HDL-c) excretion increased in the RB30 group. Fecal weight and fecal water content were higher in the rice bran added groups than those in the control group. Transit time was significantly shorter in the rice bran fiber-added groups than that in the control. Weight of the stomach and large intestine in the RB20 and RB30 groups were significantly greater than those in the other groups. Absorption rates of Ca, Mg, P, and Zn decreased significantly in the RB30 group compared to those in the other groups. A high amount of rice bran increased fecal lipids, including TC, TG and HDL-c. Rice bran increased fecal weight and fecal water content and shortened gastrointestinal transit time. However, a high level of rice bran diet decreased mineral absorption rates.

        We identified the intake pattern and consumption propensity of milk and sought improvements to promote consumption of milk. We targeted 362 preschool children aged 5~7 years old who attended nursery school in the Bucheon area. Questionnaires were distributed and 328 questionnaires were collected. Approximately 36.2% of boys and 31.2% of gorls drank milk six times per week. A total of 32.9% of the preschool children drank more than 2 cups of milk/day. Approximately 72.9% of them currently drink white milk, and 46.0% preferred milk to processed milk. The reasons why they drink milk included ``want to be tall``(66.5%) and ``good health``(52.4%). Mothers(54.6%)and preschool children(39.3%) were the purchasers with the greatest impact on product purchases. Consumer propensity to buy milk was shown in the order of expiration date(4.80 points), and nutrition facts(4.01 points). (4.88 points) and enhanced nutrients(4.59 points) should be promoted for milk consumption. Therefore, it is thought that continuous nutrition education should be made together in order to increase consumption of milk of children and education targeting teachers and school parents should be conducted as well. And in order for children to drink milk without repulsion, the development of various products satisfying both symbolic aspects and nutritional aspects should continue to be made.
