  • The present study was performed to assess nutritional status of thiamin in 104 elementary school children, living in rural areas of Chungbuk. Dietary intake was obtained by 24 hour recall method and blood was collected to analyze the transketolase activity in erythrocytes. Average dietary intake of thiamin was found to be adequate (1.l5mg, 109.2% of RDA), even though dietary intake of energy was not more than 1,719kcal, 81.5% of RDA. Transketolase activity in erythrocytes was distributed in the range of 0.294-0.744mU/mgHb and the mean value was 0.540mU/mgHb. The mean value of TPP effect was 7.9% and the range was 0-77.4%. It appeared that 7.7% of children were deficient in thiamin, severely or marginally. There were no significant correlations between transketolase activity and dietary thiamin intake, and between TPP effect and dietary thiamin intake. Mean DVS (Dietary variety score) of the children was 14.2${\pm}$3.2 and DVS was apparently correlated with thiamin intake.

  • Korean foods have the strengths to addresssome of the health problems of modern man. To assess the properties of Korean noodles, daily value %, DVS, DDS and energy density were compared between many kinds of noodles from around the world. Using a variety of reference materials, a nutritional database of noodles was built for this study. For carbohydrate, lipid, vitamin A, vitamin K, vitamin C, niacin, zinc, and copper, the daily values % of western noodles were significantly higher. Also, the serving size of Korean noodles was significantly small. Comparing the average energy density of the noodles, they showed $1.87{\pm}0.93kcal/g$ (Korean noodles), $2.42{\pm}1.08kcal/g$ (western noodles) and $1.84{\pm}0.84kcal/g$ (other noodles). The dietary fiber, polyphenols, and flavonoids content of the noodles showed no significant difference. Neither DVS nor DDS showed a statistically significant difference. In the Korean noodles, the GMDFV pattern showed a diverse choice of food groups. Korean noodles show a lower energy density, and the small serving size to have favorable for the prevention of obesity. Thus, Korean noodles are an excellent choice in terms of diversity and energy density.

  • The purpose of this study was to investigate the nutrition knowledge of kindergarten teachers and their attitude toward kindergarten lunch and snack service programs. Self-administered questionnaires were completed by 293 kindergarten teachers from January to February 1995. The results were as follows : 77.8% of the kindergarten teachers were taking part in the school meal service program. Most teachers were interested in the special training in child nutrition management, however, only 34.0% of the respondents had taken the nutrition related courses. The average score of nutrition knowledge of kindergarten teachers was 15.9$\pm$2.9 out of possible 28 points. They had better knowledge on such subjects as nutritional physiology and food choices for children, but had lower scores on practical subjects as calorie and nutrient value of food, cooking and nutrition management for children. When they chose snack items for children, teachers highly considered the nutritional value of snacks. Milk, cornflakes & milk, steamed potato, boiled egg, orange, apple and gimbap were their favorite choices for children's snacks. Other factors to be considered included children's preference, convenience in food service, and price of snack.

  • The effect heat treatment (autoclave) on nutritional value of winged bean as compared to soybean has been investigated. The winged bean and soybean were obtained from local cultivar grown in Indonesia. The beans were autoclaved at $120^{\circ}C$ for 15, 30, 45, 60 or 90 minutes, respectively before being ground for chemical analysis. Trypsin inhibitors of winged bean and soybean decreased (p < 0.05) along with decreasing of urease activity as heating time increased from 0 to 90 minutes. Heat treatment significantly (p < 0.05) reduced protein solubility in 0.2% potassium hydroxide of winged bean as well as soybean. In vitro protein digestibility was significantly (p < 0.05) improved by heating treatment (15 to 60 min of autoclaving), however, excessive heating (90 min of autoclaving) decreased the digestibility of winged beans. Excessive heating had adverse effect on lysine, cystine and methionine contents of winged beans. The results of this study suggested that autoclaving at $120^{\circ}C$ within 45 minutes should be adequate to remove protease inhibitors and could improve protein digestibility of winged beans.

  • In order to examine the possibility that oil seed rape could be used as a forage fodder crop and to select the most suitable variety of forage rape at the southern area of Korea, two varieties of oil seed rape currently grown for oil production and six introduced varieties of forage rape with relatively high yield and high nutritional value were grown at the same condition and their nutritional value were observed. Generally, rape was considered as a useful forage fodder crop with high content of crude protein and low contents of NDF, ADF, hemicellulose, cellulose and lignin. Differences in mean values of the above characters between two groups of rape were not statistically significant. Velox showed significantly higher content of crude protein and significantly lower contents of NDF, ADF, hemicellulose, cellulose and lignin compared with other varieties of forage rape. Rape was relatively high in IVDMD compared with other forage fodder crops, and forage rape was more or less higher in IVDMD and DDMM than oil seed rape. Velox was the highest in IVDMD and DDMM among the varieties of forage rape in this experiment.

  • Probiotic products have long been recognized for their health benefits. Additionally, milk has held a longstanding reputation as a dairy product that offers high-quality proteins and essential micronutrients. As awareness of the impact of food on health grows, interest in functional products such as probiotic dairy products is on the rise. Fermentation, a time-honored technique used to enhance nutritional value and food preservation, has been used for centuries to increase nutritional value and is one of the oldest food processing methods. Historically, fermented dairy products have been used as convenient vehicle for the consumption of probiotics. However, addressing the potential drawbacks of fermentation has recently led to increase in research on probiotic dairy drinks prepared without fermentation. These non-fermented dairy drinks have the advantage of maintaining the original flavors of milk drinks, containing potential health functional probiotics, and being an alternative dairy product that is helpful for probiotics intake. Currently, research on plant-based dairy products is rapidly increasing in the market. These developments might suggest the potential for novel forms of non-fermented dairy beverages with substantial prospects in the food market. This review aims to provide an overview of milk-based dairy beverages, both fermented and non-fermented, and discuss the potential of non-fermented dairy products. This exploration paves the way for innovative approaches to deliver probiotics and nutrition to consumers.

  • Fermented kale juices using four types of lactobacilli were produced in the present study. After 48 h of fermentation time, viable cell counts of all ferments reached an above $10^9CFU/mL$. The viability of the ferments after cold storage in the refrigerator for 4 weeks showed $10^8CFU/mL$ in all ferments. Among four types of fermented kale juices, the ferment of Lactobacillus acidophilus IFO 3025 indicated a good nutritional composition, including neutral sugar ($1,909.76{\mu}g/mL$), reducing sugar ($564.00{\mu}g/mL$, P<0.05), and protein contents ($160.06{\mu}g/mL$, P<0.05). The results of mineral composition analysis had the highest potassium value in all ferments ($854.16{\sim}895.07{\mu}g/mL$), particularly in the ferment of Lactobacillus brevis FSB-1 (P<0.001), which is necessary to sustain osmotic pressure, prevention of high blood pressure, and protein synthesis. Moreover, calcium, phosphorus, and magnesium contents related to bone health were generally sufficient in all ferments. Consequently, in this study, fermented kale juices may be suggested as a healthy fermented beverage with essential nutrients. However, the acceptability of the fermented kale juice to the Korean taste should be further investigated with a trained taste panel to determine whether inoculated fermentation could be an option for the consumers.

  • This review provides an overview of the published data on the canola meal and its suitability for duck as an alternative plant-origin protein source to soybean meal. Canola meal is a legume origin protein source containing comparable amino acid profile to soybean meal and rich in essential minerals and vitamins. Nonetheless, it is known to contain less in energy content than soybean meal. Factors like field conditions and processing methods creates compositional variations among canola meal. Presence of anti-nutritional factors such as phenolic substances, phytate and glucosinolates which are known to reduce growth performance in livestock animals, are the major drawbacks for canola meal to be a competitive plant-origin protein source in the feed industry. This review is focused to address i) nutritional characteristics and feeding value of canola meal for ducks and ii) impacts of feeding canola meal on performances of ducks.

  • This study was conducted to assess the nutritional status of female students in the 6th grade in a rural primary school. The anthropometric data showed their mean height and weight were 149.5$\pm$6.5cm and 41.3$\pm$7.6kg, respectively, which are slightly higher than those in the Korean Standard Growth data. It was further observed that there was a wide variation in terms of physical growth and development among subjects. The mean hematocrit value was 40.3$\pm$3.3$\%$ and the mean hemoglobin concentration was 12.9$\pm$1.0gm/㎗. It was proven that 22.8$\%$ of subjects were anemic based on the WHO standards for hemoglobin level. Twenty four hour dietary recall revealed that their food intakes of subjects was appropriate, compared to the RDA except for Ca. Mean Ca intake among subjects was 381.3mg which is 47.7$\%$ of RDA. Nutrition education from mothers and the school influence nutrient intake significantly. Special nutrition education programs targeting mothers and students should be developed to provide practical assistance such as food choice and the forming of good eating habit.
