  • Pyrimisulfan is a herbicide. In order to register this new pesticide, the series of toxicity data on animal testing were reviewed to evaluate its hazards to consumers and also to determine its acceptable daily intake. Pyrimisulfan was excreted mostly by feces. It has low acute oral toxicity while it has no dermal, ocular irritation and skin sensitization (As the result of subchronic and chronic toxicity and carcinogenicity showed changes of hematology and liver.). Two-generation reproduction toxicity, genotoxicity, carcinogenicity and prenatal development toxicity were not proven. Therefore, the ADI for Pyrimisulfan is 0.1 mg/kg/ bw/day, based on the NOAEL of 10 mg/kg/ bw/day of 90-days repeated dose oral toxicity study in dogs while applying an uncertainty factor of 100.

  • The purpose of this study was to develop nutrition education program that promotes eating behavior of preschool children. 118 parents of preschool children were surveyed to understand of children's food preferences and prejudices. The preference for vegetable showed the lowest score(2.345) and fruit was the favorite food(4.11). These results imply the consequence of teaching balanced diet with emphasizing vegetables for preschoolers. Thus, nutrition education program including teaching material were developed to provide the preschoolers with cognitive, affective, and psychomotor activities in order them to the familiar with vegetables. The program were consisted of following five parts: 1. Read-A-Story includes six stories with follow-up activities. 2. Grow-A-Plant gives instructions for growing vegetables. 3. Play-A-Game stimulates children's imagination and learning. 4. Take-A-Trip suggests places to visit that grow, sell, and prepare vegetables. 5. Eat-A-Treat presents easy ways to prepare and enjoy vegetables. Twenty one-Standardized recipes for vegetable dishes were also developed for preschooler's luncheon and snack in daycare center.

  • This study was designed to examine the effect of microencapsulated iron-fortified Cheddar cheese and L-ascorbic acid as a bioavailable helper of iron on chemical and sensory aspects. Coating material was PGMS, and ferric ammonium sulfate and Lascorbic acid were selected as core materials. The highest efficiency of microencapsulation of iron and L-ascorbic acid were 72 and 94%, respectively, with 5:1:50 ratio (w/w/v) as coating to core material to distilled water. TBA absorbance was significantly lower in microencapsulated treatments than those in uncapsulated treatments during ripening. The productions of short-chain free fatty acid and neutral volatile compound were not significantly different among treatments during ripening periods. In sensory aspects, bitterness, astrigency and sourness were higher in Cheddar cheese fortified with microencapsulated iron and uncapsulated L-ascorbic acid than others. The present study indicated that fortification of iron as well as L-ascorbic acid did not show any defect problem to Cheddar cheese, and suggested the possibility of iron fortification of Cheddar cheese.

  • The AOAC Mouse Bioassay method (MBA) has been widely used for routine monitoring of paralytic shellfish poisoning (PSP) for more than 50 years. However, this method has low sensitivity and experiences interference from other components in the extract. Also, ethical issues have been raised against the continued use of this live-mouse assay. To establish an alternative method for PSP analysis, we attempted to develop PSP analysis conditions using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The LC-MS/MS analysis of reference material showed very reasonable accuracy, and the analysis time was just 15 min. However, the recovery rate of toxin spike samples using the LC-MS/MS analysis was 59.4-91.0%. We also attempted to remove the matrix effect using shellfish extracts, but recoveries of C1 and C2 did not improve. A comparison between the results of MBA and LC-MS/MS analysis revealed good correlations, with values of 0.8878 and 0.9211 for oyster and mussel matrices, respectively.

  • This study examined the traditional edible basis and ingredients of Song-gi used for Pyeon of Jong-ga ancestral ritual food. Through an investigation of references, a case study, and ingredient analysis for traditional edible basis of Song-gi, the nutritional value and availability as food material were reviewed. Among the 4 kinds of pine trees from 4,705 types of edible materials usable as food listed in the ${\ll}$Korea Food Standards Codex${\gg}$, 'Pinus radiata D. Don', in which the husk is acknowledged as an edible food, was applied in this study. This study processed the Song-gi following the method of jong-ga and divided into pine inner bark (PIB) and pine inner bark powder (PIBP) to analyze the general composition and dietary fiber. The main composition of PIB was carbohydrate, in which the content was 88.7% per 100 g. The content of dietary fiber was 73.7% per 100 g and the insoluble dietary fiber reached 92.3% in total dietary fiber. In conclusion, the edibility of Song-gi, which has a considerable amount of insoluble dietary fiber caused constipation because it absorbed the moisture in the intestine due to the lack of nutrients but may be developed as a functional food that helps the digestive activation of the intestine and improve the health of the intestine if taken with balanced nutrition.

  • Changes in contents of free sugars, amino acids, and fatty acids of legumes were analyzed for each phase of in vitro digestion. In addition, contents of resistant starch in raw and digested pulses were compared. Soybeans, kidney beans, cowpeas, and chickpeas were analyzed. An in vitro digestion model was used to analyze contents of nutrients using LC-MS and GC-MS. Stachyose in kidneybean, cowpea, and chickpea increased as the digestion phase progressed. In four types of legumes, raffinose slightly decreased or showed no significant difference between the Oral phase and the BBMV phase. Content of glucose, a monosaccharide, increased during the BBMV phase. During the digestion phase, levels of free amino acids and free fatty acids also increased. Content of resistant starch was reduced compared to that in the raw material. It was 0.01g/100 g food in soybean, 1.06 g/100 g food in red kidney bean, 0.77g/ 100g food in cowpea, and 0.76 g/100 g food in chickpea. It was confirmed that nutrients in the in vitro digestion model were liberated at each digestion phase with changes in the content of resistant starch. These results are expected to be used as fundamental data for obtaining bioavailability of nutrients.

  • In this study, liquid culture of Tricholoma matsutake mycelia was performed via biomass production, and its inhibitory effects on melanin biosynthesis were evaluated. The Tricholoma matsutake mycelia extract inhibited 38.6% of tyrosinase activity at 100 ppm, which is higher than that of extracelluar medium at same dose. In addition, when 100 ppm of Tricholoma matsutake mycelia extract was treated to melan-a cells for 3 days, 19% of melanin production was reduced without cell toxicity. These results suggested that cultured Tricholoma matsutake mycelia might be useful as a skin depigmenting material.
