  • The influence of ginseng on the paste or gelatinization properties by amylograph and mixing properties by farinograph of wheat flour and on quality properties color cooking quality textural and sensory properties and reducing microbial population of LL(Long Life) noodles was studied. The contents of ginseng used were from 5% to 10% based on flour weight. The viscosity property of wheat flour with ginseng was increased the initial pasting temperature but the amylograph peak viscosity were decreased in vice versa. The farinograph absorption stability and breakdown were increased by ginseng. The whiteness of Ll nodles manufactured with ginseng was lower than that of control The shear extrusion force and hardness of LL noodles manufactured with ginseng were shown much higher value than those of control. At cooking quality examination of LL noodles manufactured with ginseng weight of cooked LL noodles was decreased but volum was appeared in ice versa,. Extraction amounts of LL noodles manufactured with ginseng during cooking were much smaller than those of control Total count of microorganism of Ll noodles manufactured with ginseng were decreased during storage at 3$0^{\circ}C$ Sensory properties of cooked LL noodles which was manufactured with ginseng showed quite acceptable. Based on the cooking and sensory evaluation test addition of 7.0% ginseng to wheat flour may be suitable for processing LL noodles.

  • Konjac gel is known as a low calorie food, because the main component is water. Mugwort has been used for food and medicine for a long time due to itsfunctional property, which contains a lot of vitamins and minerals. Therefore, konjac noodle-added mugwort was prepared. The konjac gel was made by from a centrifuge after adding water, alkali and mugwort power in konjac flour. The centrifuge was used to remove air in the gel. After centrifuging by heating the gel in boiling water for one hour, konjac noodle was made by pressing using a flat heating press. The results are as follows. In the drying process of mugwort freeze drying after blanching in 1% $NaHCO_3$ solution is better than other drying methods. The physical properties (hardness, elasticity, cohesiveness, gumminess) of konjac gel were measured with a Rheometer. The optimum processing conditions were decided by these measured values. The optimum condition of making konjac gel is 9% concentration of konjac flour, a ph of 12.0, $Na_3PO_4$ coagulant and 1.5% concentration of mugwort power in konjac flour.

  • The influence of organic acid dips on the quality properties, color, cooking quality, textural and sensory properties, and reducing microbial population of LL(Long Life) noodles was studied. The contents of organic acid used were 0.2% based on flour weight and LL noodles were treated by dipping in pH $2.5{\pm}0.1$ for $60{\sim}90sec$. The whiteness of LL noodles treated with dl-malic acid was higher than that of others. The shear extrusion force and hardness of LL noodles treated with dl-malic acid were shown much higher value than those of others except treated with dl-malic acid. acetic acid(=1:1). At cooking quality examination of LL noodles treated with organic acids, weight of cooked LL noodles treated with dl-malic acid was decrease but volume was appeared in vice versa. Extraction amounts of LL noodles treated with dl-malic acid, dl-malic acid : acetic acid(=1:1) during cooking were much smaller than those of others. Total counts of microorganism of LL noodles treated with dl-malic acid,dl-malic acid. acetic acid(=1:1) were disappeared during storage at $30^{\circ}C$ but treated with latic acid, acetic acid were increase during storage. Sensory properties of cooked LL noodles which was treated with dl-malic acid showed quite acceptable.

  • The purpose of this study was to examine the effect of nutrition education about the Korean food guide to middle school students on food intake measured by food frequency. Three hundred first graders were sampled from two coeducational middle schools located in the small city of Chungnam area, and divided into 167 (74 boys, 93 girls) education groups of one school and 133 (70 boys, 63 girls) non education groups of the other school. Nutrition education was given to the education group for a total of 16 hours and no education to the non education group during the same period. After education, average nutrition knowledge scores of education group increased from $6.40\pm2.17\;to\;6.81\pm1.56$ significantly especially boys with a high range of increase and girls no increase. Dietary habit scores improved significantly from $46.2\pm6.5\;to\;49.1\pm6.2$ in both boys and girls of education group. Of the knowledge and dietary habits, ability of choosing a balanced meal, biased eating to some food, and taking diverse foods at every meal improved significantly in education group. In non education group no significant increases of either nutrition knowledge scores and dietary habit scores were shown. In addition education group showed significant increases after education, in the intake frequencies of rice$\cdot$noodle$\cdot$loaf bread, kimchi, green and yellow vegetables, and soybean$\cdot$soybean curds by 0.27, 0.23, 0.40 and 0.32 servings per day, compared with non education group. These changes were greater in girls than in boys. According to these results, it can be concluded that nutrition education about the Korean food guide improved effectively not only student's nutrition knowledge and dietary habits, but also healthy food intake ability. It is necessary to prepare long-term and continuous school-based nutrition education programs for the students to get into a habit of healthy food intake.
