  • This study was conducted to select pepper lines that were tolerant to excessive water injury among the pepper germplasm and investigate the genetic characteristics of those lines to contribute to the breeding of pepper cultivars with stable productivity in abnormal weather. Each of the tolerant and susceptible lines went through immersion treatment, and differentially expressed genes between them were analyzed. The tolerant line showed increased expression of the CA02g26670 gene, which is involved in the CONSTANS protein pathway and regulation of flowering by day length, but it exhibited decreased expressions of CA01g21450, CA01g22480, CA01g34470, CA02g00370 and CA02g00380. The susceptible line showed increased gene expressions of CA02g09720, CA02g21290, CA03g16520, CA07g 02110, and CA12g17910, which are involved in the inhibition of proteolytic enzyme activity, DNA binding, inhibition of cell wall-degrading enzyme, and inhibition of nodulin, respectively. Meanwhile the expressions of CA02g02820, CA03g21390, CA06g17700 and CA07g18230 decreased in the susceptible line, in relation to calcium-ion binding, high temperature, synthesis of phosphocholine and cold stress, respectively. The expressions of genes related to apoptosis and peroxidase increased, while that of CA02g16990, which functions as a nucleoside transporter, decreased in both the tolerant and susceptible lines. Based on the different gene expressions between the tolerant and susceptible lines, further studies are needed on breeding abiotic stress-tolerant lines.

  • The effect of various vegetables commonly consumed by Koreans on the induction of glutathione S-trasferase(GST) activity in mice was assessd. The extract of vegetable dissolved in propylene glycol (5ml/kg body wt.) was administered to ICR female mice 6 to 8 weeks old via gavage during 5 days. The changes of body weight and liver weight of all treated groups were not significantly different compared with control group. Hepatic protein contents of trated groups compared with control group were not significantly different except BHT treated group. The induction of GST activity in liver cytosol of mice was the greatest with broccoli, followed by radish, wild green onion, turnip, and green onion. The induction of GST activity in liver cytosol increased up to 1.5 to 1.8-folds at a dose of 24 g fresh vegetable/mouse. The induction of combination between vegetables was the highest with the combination of broccoli and radish (1.83-fold), followed by that of broccoli and green onion (1.72-fold), and that of broccoli and turnip (1.50-fold).

  • To assess diet quality by food group intake and to investigate the interrelationship of age, dietary diversity score(DDS), dietary variety score(DVS), dietary frequency score(DFS), food group intake and nutrient intake with food group intake, a dietary survey was conducted with 176 preschool children aged 1 to 6 in Busan using a 24-hr recall method. Food group intake was assessed by food number consumed and intake frequency by six food groups(grain, meat, vegetable, fruit, dairy, sweets group). The mean food numbers consumed and intake frequencies by six feed group were 3.1 and 4.0 in the grain group, 3.6 and 4.0 in the meat group, 3.5 and 4.1 in the vegetable group, 1.0 and 1.1 in the fruit group, 1.3 and 1.5 in the dairy group, 1.4 and 1.4 in the sweets group respectively. As age increased, the intake frequency of the grain group(p<0.05) increased but that of the dairy group(p<0.05) decreased significantly. The DVS and DFS didn't show significant correlations with intake frequency of the dairy group. The grain group intake had significant positive correlations with intakes of the meat, vegetable, and fruit groups. The vegetable group intake had signigicant positive correlations with intakes of the grain and meat groups. The dairy group intake had significant positive correlation with sweets group intake but negative correlations with intakes of the grain and vegetable groups. As the intake frequency of the meat group increased, the NAR(nutrient adequacy ratios) of all nutrients and NAR(mean adequacy ratio) increased significantly. NARs of provein iron, vitamin B$_1$, niacin had the highest correlation with the meat group intake and those of protein, calcium, phosphorous, and vitamin B$_2$ had the highest correlation with the dairy group intake. NARs of vitamin A and vitamin C had the highest correlation with intake of the vegetable and fruit groups respectively. Children with food number consumed and intake frequency of above 6 and 4 in the grain group or above 6 and 6 in the meat group or above 4 and 8 on the

  • Despite well established health benefits, today's children do not eat enough vegetables. The purpose of this study was to determine the association between the number of unfamiliar foods in the vegetable food group and the preference for these foods and dietary factors. Subjects were 1,072 children in 5th and 6th grades from elementary schools located in 4 cities in Gyeonggi-do, Korea. A two-page questionnaire consisted of questions asking about the subjects' preference and familiarity for 64 foods in the vegetable group, preferences for three fast foods, four types of vegetable dishes, and six tastes. Also included in the questionnaire were questions assessing subjects' adherence to national dietary guidelines. The subjects were divided into quintiles according to the number of unfamiliar vegetables; the 1st quintile (N=226) was children who had less than 14 unfamiliar vegetables and the 5th quintile (N=229) was more than 29. Compared to the children in the other quintiles, the children in the 5th quintile had a significantly lower adherence to national dietary guidelines regarding consumptions of vegetable and protein sources, regular exercise, awareness of desirable height and weight, and reading food labels, as well as total (P<0.05). The preferences for bland tastes (P<0.05), salads (saengchae, P<0.01), stir-fried vegetables (P<0.01), and several vegetable items (P<0.05) were significantly lower in the 5th quintile compared to the other quintiles. This study proposes the potential benefits of teaching children names of a variety of vegetables to improve their dietary factors such as food preferences and dietary habits.

  • Objective: This study was conducted to evaluate nutritional value and in situ degradability of fruit-vegetable byproducts and their feeding effects on performance of growing Hanwoo steers. Methods: Nutritional value and in situ degradability of cabbage, Chinese cabbage and fruit-vegetable byproducts were assessed. In vivo feeding trial was also performed for 12 weeks. Thirty-six growing steers were randomly allocated into three groups according to body weight (BW) and age in 12 pens (4 replications/treatment) and assigned to one of the three dietary treatments: control (byproduct 0%), FV-B (fruit-vegetable byproduct 20%), and CA-B (cabbage peel 15% plus Chinese cabbage peel 15%, total byproduct 30%). Results: The crude protein contents of cabbage, Chinese cabbage and fruit-vegetable byproducts were 18.69%, 20.20%, and 10.07%, respectively. Concentrations of neutral detergent fiber (NDF) were higher in cabbage (22.31%) and Chinese cabbage (28.83%) than fruit-vegetable (13.94%). Higher concentrations of non-fiber carbohydrate were observed for fruit-vegetable (66.72%) than cabbage (44.93%) and Chinese cabbage byproducts (24.69%). The effective degradability (ED) of both dry matter (DM) and NDF for fruit-vegetable byproduct (DM, 84.69%; NDF, 85.62%) was higher (p<0.05) than cabbage (DM, 68.47%; NDF, 55.97%) and Chinese cabbage byproducts (DM, 68.09%; NDF, 54.22%). The DM intake was not different among treatments because the amount of feed was kept constant according to the BW of growing steers to prevent overweight during the growing period. The average daily gain during the whole experimental period was not different among treatments (1.26, 1.25, and 1.34 kg/d for control, FV-B, and CA-B). The ED of both DM and NDF degradability of the total mixed ration (TMR) diets were very similar among treatments. Feed conversion ratio during the whole period showed no significant difference among treatments. Conclusion: This study demonstrates that fruit-vegetable and cabbage byproducts up to 20% and 30% (as fed basis), respectively can be included in TMR diets for growing beef cattle.

  • Purpose: This study examined the association of fruit and vegetable consumption with asthma in Korean adults. Methods: Data on 16,528 adults aged 19-64 were collected from the Korea National Health and Nutrition Examination Survey (KNHANES). The general characteristics of the subjects, daily food intake, and daily energy and nutrients intake were investigated according to fruit and vegetable consumption. All statistical analyses were conducted based on SAS software version 9.4. Results: The prevalence of doctor-diagnosed asthma was 2.6%, and ranged between 1.8% and 3.1% depending on fruit and vegetable consumption. As fruit and vegetable consumption increased, the individuals showed a higher average age and household income, but a lower educational level, smoking rate, and frequency of alcohol consumption. The group with higher fruit and vegetable consumption had higher intakes of all food groups without milk and dairy products and energy and nutrients than the counterpart group. For the intake rate of energy, the group with higher consumption of fruit and vegetables had a higher intake rate of carbohydrate and protein and a lower intake rate of fat. The risk rate of asthma with the third quartile group regarding fruit and vegetable consumption was 35%-40% lower than that of the first quartile group. Conclusion: The results suggest that adequate consumption of fruit and vegetable will help to improve the risk of asthma. Moreover, prospective cohort studies and clinical test research are necessary to measure the effects of fruit and vegetable consumption on the occurrence of asthma.

  • The effects of enzyme combination, pH, acid washing and enzyme treatment sequence were investigated in the hydrolysis of soy protein. Comparing Alcalase vs. Neutrase/Alcalase, it appeared that Neutrase/Alcalase was more efficient than Alcalase alone, as the highest degree of hydrolysis (DH) was seen in Neutrase/Alcalase. A surprisingly high DH (more than 60%) was observed with Flavourzyme in the second hydrolysis. The separation of insolubles from the first hydrolysis had little effect on the second hydrolysis. When the washing water from the first hydrolysis was reused in the next hydrolysis, the DH and protein recovery were increased. The addition of calcium ion showed not so much positive effects by the stabilization of Neutrase on the Protein hydrolysis. The use of carbohydrase and repeated acid washing gave positive effects on DH. The simultaneous treatment using endoprotease and exoprotease with pH adjustment improved DH significantly.

  • The purpose of this study was to propose the appropriate sizes and dish combination for nutritional-balanced lunch boxes delivered to children under the government-funded meal service program in Korea. The study was based on the 3 : 1 : 2 Meal Box Magic, a nutrition education method developed in Japan. A total of 290 lunch menus, comprising of 10 day menus from 29 organizations having delivered lunch boxes to children during summer vacation of 2008, were analyzed and used as the base data for lunch box combination. Dishes of the menus were classified into 6 groups: Rice group, Protein side dish group (including meat, fish, egg, and bean dishes), Vegetable side dish group, Kimchi group (including kimchi and jangajji), Soup stew group, and the other group. Nutrient analysis was conducted for 100 ml of these dishes by CAN Pro 3.0 utilizing volume and weight conversion data used for analysis of the Korea Health and Nutrition Examination Survey and those from the Nutrient Composition of Food for Consumers. All the possible combinations of 5 dishes, comprising of 3 dishes from Rice group, Protein side dish group, and Kimchi group, respectively, and 2 dishes from Vegetable side dish group, were made using the frequently served dishes from the respective dish group. Nutrient analysis of each combination was conducted based on the assumption that a lunch box was 600 ml and filled up to 80% by dishes using the volume ratio of 3 : 1 : 1.5 : 0.5 for Rice group : Protein side dish group : Vegetable side dish group : Kimchi group. The mean and standard deviation of energy and nutrients of all combinations calculated by weighting the serving frequency of each dish selected for the combinations were $621\pm81$ kcal for Energy, $22.1\pm5.0$ g for Protein, $120\pm45$ mg for Calcium, $4.1\pm1.1$ mg for Iron, $201\pm130\;{\mu}g$ RE for Vitamin A, $0.34\pm0.10$ mg for Thiamin, $0.27\pm0.10$ mg for Riboflavin, and $24.3\pm9.6$ mg for Vitamin C. The energy percentages from Carbohydrate, Protein and Fat were 66%, 14% and 20%. The analysis results met the nutrition standard of lunch boxes for male elementary students in grades 4 through 6 under the government-funded meal service program regarding calories, nutrients except calcium and riboflavin, and macronutrient distribution ranges. Accordingly appropriate box sizes were suggested for different age and sex groups to meet the respective nutrition standards. In addition, milk or dairy products were suggested to accompany lunch boxes to supplement calcium and riboflavin intake. The method of selecting box sizes and making dish combination suggested in this study could be useful for the organizations preparing lunch boxes under the government-funded children's meal service program where nutrition professionals are not available.

  • Korean foods sold restrant and hotel accompaines so many kinds of side dishes. The menues never considered on the nutritional standpoint nor the volume that can be eaten by customers. The purpose of this study is to simplify and improve the menu of Korean foods sold in restrant. To find out the problem and the method of the betterment Korean food sold in restrant. The survey study was made for 100 restrants in Seoul city. Ther average number of side dish of the restrant food was 23. The average amount number of the side dish was 31 and smallest number was 4. The average amount of food served was 979 grams and the average number of food taken by people was 698 grams. The average percentage of intake of food was 62%. Protein Content of the foods sold restrant was from 54% to 240% over the recommended dietary allowances. Protein intake also exceeded from 19% to 147% of recommended dietary allowances. Age of the customers were surveyed to set up the standard amount of the nutrients. About 68% of the customers were from 30 to 40 years of age in the day time (lunch), whereas about 72% were from 20 to 30 years of age in the evening (supper). From the results of the survey study, two nutritional standard were decided to be used. One is the recommended dietary allowences of 25 years of man (reference man), and the other is that of 45 years of man. The actual standards are as follows : Standard 1 (25 years of man) Calories-900~1000Cal Protein-25-30g Vegetables-200~250g (include yellow, green vegetable), Amount of food-about 800g Standard 2 (45 years of man) Calories-700~800Cal Protein-25~30g Vegetables-150~200g (include yellow, green vegetable) Amount of food-700g The kinds of food recommended to be sold in the restrant are as follows : 1. Pansang-is a formal method of korean table setting 3 types, 7 chup, 5 chup, and 3 chup were studied and made, 2. Table for the quest with drink-2 types of table setting, 9 kinds of food and 7 kinds of foods were studied. 3. free meal-in this table, one pig protein dish with kimchi, one vegetable, and one salty flsh will be served, 19 kinds of foods were studies. 4.
