  • The purpose of this study was to investigate the primary school students' and their mothers' vegetables preferences. Total of 360 students and their 360 mothers in Seoul and Gumi-si were participated in survey during July, 2011, and data of 253 students and their 253 mothers(70.3%) were analyzed by SPSS ver 12.0. The preference scores of mothers were higher than those of students in all kinds of vegetables examined, except bean sprout and laver. The preference scores of lower grader(2, 3 grade) were higher than higher graders(5, 6 grade), and those of female student were higher than male students. The preference accordance degree of students and their mothers were highest in seaweeds group, and lowest in root stalk vegetables. The onion, welsh onion, water dropwart, mustard kimchi were showed specially low student-mother preference accordance. Among the 50 vegetables investigated, all mother had chance to eat was 31 vegetables, and all students had chance to eat was 10 vegetables. The 3 kinds of seaweeds such as seastaghorn, ceylon moss and seaweed fusiforme were the foods that more than half of student had no experience to taste. Environmental variables, such as having the sibling, whether or not mother had job, the type of breakfast foods, and food and frequency of eating-out, all had no significant influences on vegetables preferences.

  • This study investigates the change of level of psychosocial factors of decisional balance, processes of change, and self-efficacy after nutrition education on vegetable and fruit intake of children in pre-action stages. Forty-seven 5th grade elementary school children in Yeongi-Gun, Chungnam-Do were categorized into pre-action stages from a total of 71 children by four-stage questions, and then finally into two stages of precontemplation and contemplation & preparation. After 6 weeks nutrition education, recognition of both of pros and cons of vegetable intake were improved in the two groups of precontemplation and contemplation & preparation. In fruits intake, however, recognition of pros was not changed after nutrition education in either stage, but recognition of cons was improved only in the precontemplation stage. However, no difference in any psychosocial variables was found between precontemplation stage and contemplation & preparation stage. After the nutrition education, the score of consciousness raising of vegetable intake belonging to cognitive process of change increased in the subjects of the precontemplation stage, wheres the scores of dramatic relief, self-reevaluation, environment reevaluation and social liberation increased in the group of contemplation & preparation. In fruit intake, however, no change was found except in the environment reevaluation in the precontemplation group. The behavioral process of change of vegetable and fruit intake did not show any change in either group after nutrition education. Self-efficacy scores of vegetable intake of keeping the foods at hand, eating the recommended number of servings and making time to eat increased in the precontemplation group, while in the contemplation & preparation group, self efficacy scores of shopping for a variety of vegetables, instead of keeping the foods at hands, as well as the scores of the rest two items of eating the recommended number of servings and making time to eat increased after nutrition education. However, in case of fruits intake, no difference was shown in the precontemplation stage except an item of keeping the foods at hand. The results indicated that the stage of change was progressed in the pre-action stage after nutrition education and the scores of many psychosocial factors increased in both pre-action stages. It is suggested that the recognition of cons as well as the cognitive process of change and self-efficacy could be best used as indicators of the assessment of nutrition education program for vegetable intake.

  • Nitrate contents of lettuce and chinese cabbage which aye consumed mostly in vegetables in Korea were $403\~6,935$ (mean 3,088), $31\~5,391$ (mean 2,412), and $310\~6,374$ (mean 3,017) mg/kg, respectively. Nitrate contents of root vegetables and fruit vegetables were lower than those of leaf vegetables. There was no different of nitrate content in vegetables by area, but the nitrate contents of summer vegetables were higher than those of winter vegetables. Nitrate contents of Danmugi, Kimchi, and Young radish Kimchi were 346, 1,411, and 3,240 mg/kg, respectively. Nitrate contents of juice of Danmugi, Kimchi, and younger radish Kimchi were 340,979, and 1,383 mg/kg, and there was no different of nitrate content by area.

  • Although bacterial outbreaks from ready-to-eat foods have increased, little information is available on microbial quality of sprouts in markets. Fifty sprouts and 30 salads were collected from wholesale markets. Total aerobic count (TAC), coliform, Escherichia coli, and some pathogens were detected. TAC for sprouts was 7.95 log CFU/g and 6.70 for salads, indicating that sprouts were more contaminated by 1 log CFU/g than that of salads. The numbers of coliform were 6.69 log CFU/g for sprouts and 5.42 for salads. E. coli was detected in 16 of 50 sprout samples at 2.38 log CFU/g and eight of 30 salads at 2.21 log CFU/g. Bacillus cereus was detected in 29 of 50 sprout samples and 16 of 30 salads, and the counts were mostly <3 log CFU/g. Salmonella, Staphylococcus aureus, Listeria monocytogenes, Campylobacter jejuni, and Clostridium perfringens were not detected. Therefore, although pathogens may not be a high risk for these foods, the high TAC and E. coli contamination require improved production and distribution methods, particularly for sprouts.

  • Cherry tomatoes, cucumbers and zuchinis stored in the far-infrared radiated chamber at 5$^{\circ}C$ or 10$^{\circ}C$ under 90% of relative humidity had been maintained in the fresh state for longer times than the control stored only in the cold chamber. Vegetables stored in the far-infrared radiated chamber showed lower values in weight loss rate, microbial colony count and decay ratio and higher ascorbic acid content than the control stored cold in the cold room through the storage period. We confirmed that vegetables stored in the far-infrared radiated chamber under low temperature and high humidity showed least changes in quality properties through the storage period and the far-infrared radiated facilities could be a good storage system.

  • Vegetables are rich sources of dietary fiber, which exhibit various health benefits. In the Republic of Korea, vegetables are consumed after cooking using different methods. However, they are most commonly eaten raw or blanched. In this study, chamnamul, sesame leaf, Fischer's ragwort, burdock root, and garlic stem from Korea were analyzed according to the Korean Food Code, and changes in dietary fiber content after blanching were compared. Blanching reduced the total dietary fiber (TDF) content in chamnamul (from 3.67±0.03 to 2.61±0.14 g/100 g), burdock root (from 4.95±0.40 to 3.89±0.10 g/100 g), and sesame leaf (from 4.32±0.12 to 3.65±0.17 g/100 g), but increased it in Fischer's ragwort (from 6.09±0.49 to 6.43±0.01 g/100 g) and garlic stem (from 4.52±0.35 to 5.09±0.04 g/100 g). Sucrose, glucose, and fructose were detected in the vegetables; however, sesame leaf did not have sucrose. Fresh burdock root had the highest sucrose content (1.71±0.07 g/100 g) whereas garlic stem had the highest glucose and fructose content (1.65±0.02 and 1.73±0.02 g/100 g, respectively) compared with other vegetables. Upon blanching, the free sugar content of vegetables decreased for all sugars except for sucrose, which increased in Fischer's ragwort (from 0.10±0.01 to 0.14±0.01 g/100 g) and garlic stem (from 0.76±0.00 to 0.83±0.01 g/100 g). These results can provide information on blanching-associated changes in the content of dietary fiber and free sugar in foods prepared using these vegetables.
