  • The purpose of this study is to investigate the properties of traditional Korean ash glazes by using locally available sources; 10 kinds of grain stems,2 kinds of husks (pod, chaff), and 4 kinds of vegetables (spinach, radish leaf and stem, pumpkin leaf and stem, pepper stem), and to develop their practical uses as ash glazes. The test results of these ash glazes indicate that these ashes can be classified into four categories. The first group, which includes perilla stem ash, sesame stem ash, black bean stem ash and red-bean stem ash, shows strong milky white due to relatively lower content of $SiO_2$, and relatively higher content of CaO and P$_2$O$\_$5/ content (10% higher than others), and their glazes were found to be suitable for opaque glaze as they show relatively stable bright greenish color. The second group includes pepper stem ash, spinach ash, pod ash, radish leaf and stem ash, and bean stem ash, and this group was found to contain even quantity of every component. And their glaze show somewhat greenish color because of especially high content of MgO and more than 2% of Fe$_2$ $O_3$. They were found to be suitable for basic glaze of IRABO glaze. The third group, which includes com stalk ash, white bean ash, pumpkin leaf and stem ash, has more $SiO_2$ and Al$_2$ $O_3$ than other ashes, and it also contains 3~5% of Fe$_2$ $O_3$. As a result of those components, this third group shows the greatest change of color and chroma, and was found to be suitable glazes as basic glaze of Temmoku and black glazes. The fourth group (reed ash, rice straw ash, indian millet stalk ash and chaff ash) has as much as 45~82% of $SiO_2$ and relatively lower content of Fe$_2$ $O_3$ and P$_2$ $O_3$. This group shows blue or greenish white color, and was found to be suitable as the basic glaze of white glaze.

  • Quantitative determination of sulforaphane, S-methylsulfinylbutyl isothiocyanate in 20 cruciferous vegetables of Korean origin was performed. Homogenate of vegetable was extracted with dichloromethane, and the extract, after drying, was subjected to GC/MS analysis, which was based on single ion monitoring (SIM) at m/z 72, 160, 55, 114 and 177. The content of sulforaphane was found to be the highest in the extract of broccoli $(80.2{\sim}617.7\;ppm)$ followed by turnip $(15.4{\sim}23.1\;ppm)$, red cabbage $(9.9{\sim}32.1\;ppm),\;radish\;(5.5{\sim}8.8\;ppm)$ and kale (8 ppm). Among various cultivars of broccoli, broccoli '1243' and broccoli 'Pilgrim' showed higher content of sulforaphane than others. Especially, in the stem of broccoli '1243' and the floret of broccoli 'Pilgrim' the amount of sulforaphane was the highest (>700 ppm). Thus, the content of sulforaphane differed according to the cultivars and the portion of the vegetables.

  • This study systemically analyzed the data on the microbial levels in fresh vegetables in Korea to identify the points to control. We scanned the studies published between 2001 and 2015 in peer-reviewed research papers on the microbial levels in fresh vegetables produced in Korea. Plant products were categorized by using the US IFSAC (Interagency Food Safety Analytics Collaboration) category. The most consumed, the non-heat treated, the epidemiological foodborne diseases sources of fresh vegetable in foodservice (KCDC data) were identified by literature review. Articles were screened using National Digital Science Library (NDSL) search engine regarding to microbial hazards in plant products. Based on the total plate count number and coliforms on the 89 data cases from 26 published articles, the total plate count number was high in the order of sprouts, leaf and stem, bulbs and roots, vine-grown, solanaceous, melons, and pome. Escherichia coli was frequently detected in leaf and stem and sprouts products. Focused on the microbial data of leek, lettuce and cabbage, the levels of total plate count, coliforms and Bacillus cereus showed the levels of 4.15~7.69 log CFU/g, 1~6.99 log CFU/g, and 0.51~3.9 log CFU/g, respectively, by 33 published papers. The levels of environmental factors affecting the microbial safety of lettuce and leek before harvest were investigated. Manure, soil, hands, scale, gloves were the major potential microbial contamination points to control. In addition, GAP (good agricultural practice), microbial testing, and improvement of irrigation methods are required to provide the safer fresh produce.

  • Current study aimed to evaluate elementary school children's perception and eating attitude towards vegetables and analyze environmental factors influencing it. Survey was conducted among elementary school students and their parents in Gangwon district, 410 subjects each(Total 742, 391 students, 351 parents). The results are as follows. Both the children(64.3%) and the parents(84.9%) showed high concern over health. 46.6% of children and 52.4% of parents admitted unbalanced eating behavior, and commonly avoided foods were mostly vegetables such as mushroom, carrot, garlic, sweet pepper-green, welsh onion, kimchi, pumpkin, or beans. Unbalanced eating habit was significantly related to health consideration in choosing what to eat(p<0.01) and interest in health(p<0.05). 70.9% of children with unbalanced eating habit showed intention for correction, and those with high interest in health had stronger intention (p<0.01). Regarding children's perception of 20 kinds of vegetables frequently used in school lunch, swiss chard leaf beet, amaranthus magistratus, and curled mallow were rarely heard of or hardly eaten before. Korean chinese cabbage, radish(62.7%), cucumber(62.1%), perilla leaves(60.4%), lettuce(58.1%), and spinach(54.5%) were among the most frequently eaten. Survey result on children's preference for the vegetables shows lettuce, cucumber, Korean chinese cabbage, perilla leaves, spinach, and radish were highly preferred and stem of garlic, crown daisy, sweet pepper-green, pepper, and curled mallow were the least preferred. There was a significant positive correlation(p<0.01, p<0.001) between children's and their parent's preference for each vegetables, implying that children's preference towards vegetables is greatly influenced by their parent's choice. Children showed negative attitude towards vegetables with strong flavor and tended to avoid vegetables that they remember as not tasty. This suggest that strong flavor and negative prior experience is what determines children's attitude in vegetable consumption. Many children said they try to eat vegetables even if they haven't had it before, and this tendency was significantly correlated with the degree of interest in health(p<0.05) and the degree of consideration of health in choosing what to eat(p<0.001).

  • This study aims to investigate the food preservation methods adopted by the Joseon Dynasty, which existed before the 17th century. A total of 232 food preservation methods were discovered in 25 books, and could be classified by their targeted food types: vegetables (84), sea foods (60), meats (41), fruits (37), and others (10). Depending on the preservation method applied, they are classified as food drying, soaking, mud cellar preservation, and other preservation. Food drying is further classified into 8 sub-types: drying, sun-drying, shadow-drying, wind-drying, dry heat, combined drying, smoking, and others. Soaking could be sub-divided into using salt, ash, dry sand, bran, fermented paste, wet distillers grains, oil, and others. Mud cellar preservation is sub-classified into installing shelf inside the mud cellar, making the mud cellar for food preservation, and making hole or underground tunnel for food preservation. Other food preservation methods include minimizing moisture loss by applying beeswax on a section of the vegetable stem, and cutting the vegetables or fruits with their branches and leaves for food preservation.

  • The purpose of this study was to evaluate the daily vegetable and fruit intake status of Korean adults and to examine the relationship of vegetable and fruit intake with bone metabolism. The vegetable and fruit intake of 542 healthy male and female adults was analyzed. Then, by selecting 51 targets from the subjects, the relation of vegetable and fruit intake with serum calcium, osteocalcin and deoxypyridinoline (DPD) excretion in urine was examined. The total vegetable intake per day was 397.7 g and 333.5 g by men and women respectively for the age group of 20-29, 366.9 g and 309.2 g respectively for the age group of 30-49, 378.4 g and 325.9 g respectively for the age group of 50-64. Of vegetable varieties, leafy and stem vegetables displayed the highest intake. The order of major intake items of vegetables and fruits was found to be Chinese cabbage kimchi, onion, radish, cucumber, and welsh onion for the age group of 20-29, watermelon, Chinese cabbage kimchi, peach, potato, and onion for the age group of 30-49 and watermelon, Chinese cabbage kimchi, tomato, potato, and peach for the age group of 50-64. Of 51 targets, ${\beta}$-carotene intake displayed a significantly negative correlation with serum osteocalcin. While caloric intake as well as protein, carbohydrate, calcium, phosphorous, zinc and total food intake displayed a significantly negative correlation with DPD excretion in urine, tuber vegetable intake displayed a significantly positive correlation with DPD excretion in urine. In the future, a study will be necessary to accurately explain the relevance of vegetable and fruit intake with bone mineral density and bone metabolism. Also, efforts will be required to increase vegetable and fruit intake.

  • This paper describes a naturally occurring case of meningoencephalitis associated with Listeria monocytogenes in a 4 month-old Korean native goat. The goat was raised in a herd consisting of seventy goats, and fed on straw and leftover vegetables including onions, cauliflower, and bean sprouts. The clinical symptoms of the goat were depression, in appetence, anorexia, circling, and recumbency before death. No conspicuous gross lesions were found except consolidation of the lung. Histopathologically, severe multifocal microabscesses and perivascular cuffings were observed in the brain stem and mid brain. In addition, mild nonsuppurative meningitis in the cerebrum were seen in this case. The organism isolated from the brain stem was confirmed as L. monocytogenes using the biochemical tests and PCR assay. Based on clinical signs, histopathology, and bacterial isolation; we confirmed that this case was a typical encephalitic listeriosis.

  • This study aimed to investigate pesticide residues in 160 stalk and stem vegetables marketed in Northern Gyeonggi-do. The QuEChERS method using GC-MS/MS and LC-MS/MS was employed to analyze the residues of 341 pesticides in the samples. The maximum or lower than the residue limit was recorded in 75 samples (46.9%), while 4 samples (2.5%) exceeded the maximum residue limit (MRL). Thirty-nine kinds of residual pesticides were detected including fungicides (14), insecticides (22), herbicides (2), and plant growth regulator (1). Carbendazim and pendimethalin were the most frequelntly detected pesticides. Fenitrothion, procymidone, and diazinon exceeded MRL in garlic chives, and Welsh onion. This indicated that these vegetables along with water celery should be constantly monitored.
