In this study, the dietary fiber content of 33 kinds of agricultural products and seaweeds was compared with that of raw products after heat treatment. To verify the total dietary fiber analysis method, the recovery rate was reviewed by measuring the total dietary fiber content for 4 standard certified substances. As a result, the recovery rate of the analysis value for the true value was 98.8%~103.1%, which was judged to be reliable. The total dietary fiber of vegetables ranged between 0.61~5.36 g/100 g for raw vegetables and 0.55~4.84 g/100 g for heat-treated vegetables. Among the 24 kinds of vegetables used in the analanalysis, the total dietary fiber content of heat-treated Korean radish (3.13 g/100 g) was the highest compared to that of raw radish (0.61 g/100 g). The total dietary fiber of beans was between 13.86~29.69 g/100 g for raw beans and 6.72~18.40 g/100 g for heat-treated beans. In particular, the total dietary fiber content of sword beans was the highest in both raw (29.69 g/100 g) and boiled (18.40 g/100 g) beans. The total dietary fiber content of the three types of seaweed was 1.93~4.85 g/100 g in raw seaweed and 0.99~5.72 g/100 g in heat-treated seaweed.

Mineral filler is used for resin compounds, because it increases the stiffness and thermal stability of a resin compound, and it also cuts down the cost. Calcium carbonate, silica, magnesium oxide, and others are used as filler materials in general, and the type of filler material, the size, and content can affect the physical properties of compounds. Those factors also influence the viscosity of resin mixtures and the workability, and should be adjusted by changing the contents of the filler, which depends on the size. In this study, five kinds of ground calcium carbonate, which were different in size, were used to produce polyester compounds ; the physical properties were compared with the filler size and contents. The mechanical properties were measured by bending strength and tensile strength, and the heat deflection temperature was obtained for thermal stability.

Traditionally, food and medicines are considered as having common roots. That is, their energies share the same source (藥食同源), which has created a unique food culture, and nurtured a unique academic area of dietary medicine (藥膳食料 學). This study aimed to develop a desirable dietary life-style based on the oriental dietary medicine theorem originated from the schema of four qi as well as five flavors of foods (四氣五味), originated from the yin-yang and five phase theory based on a clear understanding of a modern point of view, and experimental analysis of nutrients and dietary effects of clear heat effect materials. This study can promote more healthy life-styles and prevent adult diseases by following oriental dietary medicine theory. We should develop a Yack-sun theory and dietary culture that is suitable for physical and genetic health.

마늘의 주요 저장성분인 fructan을 산 가수분해시키고 열처리에 따른 폴리페놀함량과 항산화활성의 변화를 살 펴보았다. 마늘 fructan의 최적 산가수분해 조건은0.3N H2SO4으로 5분간 반응시켰을 때로 나타났다. 열처리에 의한 fructan 함량은 열처리 온도가 증가함에 따라 240.5 mg/g에서 2.0 mg/g으로 분해되어 감소하였으며, 총 폴리페놀 함량은 열처리 온도 증가에 따라 0.85 mg/g에서 13.74 mg/g으로 증가하였고, 항산화활성 (IC50)은 열처리온도가 증가에 따라 52.9 mg/mL에서 1.5 mg/mL으로 증가하였다. 열처리 후 산가수분해시 총 폴리페놀 함량 및 항산화활성은 증가하였다. 마늘 fructan을 분해하여 식품소재로서의 활용과 동시에 항산 화활성을 강화시키기 위한 열처리 조건으로는 130℃, 2 시간 처리가 적합한 것으로 판단되었다.

Peony is a medicinal herb which have utilized widely as chineses medicine. The paeoniflorin is the predominant component In peony root, monoterpene glucoside containing pinane structure. The effective components were extracted with the cold water from the intact peony roots, and effectively extracted with 70% ethanol from the dry powder of peony roots. The changes of paeoniflorin contents were investigated during the drying process of peony roots and processing of peony extract by the heat-treatment. Air-drying was the best condition for the preservation of paeoniflorin content among the drying processes of peony roots. But convective drying at 6 was recommended for the drying process of peony roots in large scale. The paeoniflorin in peony extracts was not destroyed by the treatment at 6 and 8 for 5 hrs, but destroyed 30%, 28% and 40% of paeoniflorin by treatment at 10 for 5 hrs, 115 and 121 for 10 minutes, respectively. The paeoniflorin was continueously extracted for 4 hrs from the dry pieces of peony roots(0.50.50.5cm) in boiling water but destroyed gradually after 4 hrs at 10. Paeoniflorins in 70% ethanol extracts of peony root were not destroyed at all in the process of concentration to dry powder at 60"C on vacuum.cuum.
