Meat products have become prevalent in people's diet, and sausages, with the Korean diet getting more westernized in modern times. In particular, emerged as one of the favorite and the most consumed food products in Korea. In order to attain the best recipe to maximize the sausage's sensual taste, we have attempted to experiment and to analyze the differences in characteristic tastes of the sausages with varying increments of crushed red pepper of 0%, 2.5%, 5,%, 7.5%, and 10%. The followings are our findings from our experiment. As the result shows that red pepper, instead of nitrite, added sausage has twice more red chromaticity than those not added, sausage can be colored in red solely with natural materials when sold in the market. pH and moisture decreased as more red pepper was added, it did not show large difference. Texture results showed that the original sausage became harder and its viscosity decreased as more red pepper was added. Cohesion appeared to be similar and red pepper added sausage was munchier and more flexible. In the results of sensory test, 5% of red pepper added sausage showed the highest score but did not have any significant difference. For each items, red pepper added sausage got higher scores and by supplementing it would be seen as a useful additive in developing natural color sausages.

In this study, to improve the quality of school lunch in local colleges, we conducted a survey on students who attend 2 year colleges in Jeju region. With its own unique regional characteristics and the change of its school lunch program from direct management to consignment, there were some questions about how each factor in school lunch program affects on students' satisfaction with it and we tried to present helpful data to improve school lunch programs in each region. The survey took place from May 5 to May 10, 2005 covering the colleges only in Jeju region. There were 200 sets of questionnaires issued and distributed to the students who are currently using school lunch programs. Only 168 sets were retrieved and processed statistically. 2 sets out of 168 questionnaires had to be thrown away because there were wrong entries of some questions, which made overall retrieving rate 83%. In this study, SPSS 10.0 , one of the statistical package programs, was used as an analyzing tool to make Frequency Analysis. To verify credibility, Cronbach's Alpha Element Analysis was done and T-test and ANOVA was also made. After Recurrence Analysis for elements of satisfaction regarding main factors that is considered to be important to customers, we found that importance of following factors: appearance of food, incongruity between main and side dishes, availability of seasonal food, availability of preferred menu, absence of food stock, waiting time, accessibility of food counters, space between chairs, presentation of a menu, food tray's shape, and color of food trays. The importance of those showed high but satisfaction with the same factors was low. So the primary improvement on these factors should be made to increase satisfaction. Finally we concluded that in large extent, importance of each factor definitely affects on students' satisfaction.

겔화제의 종류에 따른 겔상식품의 특성을 알아보고자 대조군인 한천첨가 양갱과 다양한 겔화제를 혼합 사용한 양갱을 제조하고 그 특성을 비교하였다. 첨가되는 겔화제의 특성은 최종 제품의 수분손실량, 색, 조직감 등의 물리적 특성에 크게 영향을 미치는 것으로 나타났다. 덜 조밀하고 가장 불규칙적인 단면특성을 보이는 gellan 첨가 양갱은 수분 손실이 가장 크고, 가장 부드러우면서도 입에 들러붙는 부착성이 큰 특성을 보였다. 반면, LBG+carrageenan 겔의 혼합은 두 겔의 상호작용으로 단단한 겔을 만들기 때문에 이를 첨가한 양갱 역시 가장 단단한 경도를 보였다. 본 연구결과 고령자들은 너무 단단하지 않으면서도 응집성이 높고 탄력성이 있어 씹을 수 있는, 그러나 입에 들러붙는 부착성이 낮은 겔상 식품을 선호하는 것으로 나타났다. 두 종류의 겔을 혼합하여 적절한 농도로 겔을 제조하면 경도, 부착성, 및 응집성 등의 조직감 특성을 다양화 할 수 있으므로 적절한 겔화제의 선택, 농도조절 등으로 고령자의 저작능력에 맞는 다양한 물성을 갖는 식품제조가 가능할 것으로 생각된다.

In this study, the traditional takju was manufactured using the finger root, which was recognized as a health functional ingredient, and analyzed the physicochemical and sensory quality characteristics according to the period of fermentation. The pH was significantly low(p<0.05) in all samples until the second day of fermentation, and the pH tended to increase again from the third day of fermentation. The pH value was decreased as the amount of finger root was decreased(p<0.05). The acidity of takju was significantly lower at 0.17~0.21 immediately after fermentation(p<0.05). The acidity of FR0 showed significantly the highest value(p<0.05). The sugar content of takju was significantly increased in all the samples until the 2nd day of fermentation(p<0.05). On the 7th day, it showed the lowest value at $11.01{\sim}12.63^{\circ}Brix$. The sugar content of FR0 was significantly lowest value(p<0.05). The alcohol content of takju was significantly increased as the fermentation proceeded, and the highest value was 11.90~13.50% at 7 days(p<0.05). The alcohol content of RF0 was significantly higher than other samples(p<0.05). As a result of organic acid analysis of finger root takju fermented for 7 days, citric acid(3.35%) showed the highest content of FR3(p<0.05). The content of fructose increased with increasing finger root amount (p<0.05). As a result of sensory evaluation of finger root takju, FR1 and FR2 samples tended to be lower in score than FR0, and FR3 showed the highest score. The overall acceptance value of FR0 was 7.5 and FR3 was 7.57.

This study was performed to provide basic data that will predict the usefulness of buckwheat sprout as food materials. The quality characteristics of noodles prepared with buckwheat sprout powder were investigated The buckwheat sprout powder was added to the noodles in 0, 2, 4, 6, and $8\%$ in proportion to the weight of wheat flour, respectively. The added amounts of buckwheat sprout powder did not affect the volume of the noodles. The weight of noodles was decreased, whereas tumidity of the soup after cooking the noodles was increased with the increment of the amount of added buckwheat sprout powder. The color of powder mixture, wet noodles, and cooked noodles was changed by the addition of buckwheat sprout powder. Lightness(L) was decreased, whereas yellowness(b) and redness(a) increased as the amount of buckwheat sprout powder increased. In the texture analysis, hardness and chewiness of wet noodles were increased significantly by the addition of buckwheat sprout powder. Hardness, chewiness, and gumminess increased significantly in the cooked noodles with more than $6\%$ substitution of buckwheat sprout powder. Other textural properties did not show any significant changes. The results of sensory evaluation revealed that the overall preference of noodles with 2 to $4\%$ substitution of buckwheat sprout powder was better than other sample groups. Therefore, the appropriate amount of addition for the buckwheat sprout noodles was 2 to $4\%$ buckwheat sprout powder in proportion to the weight of wheat flour.
