This study was undertaken to develop web-based nutrition information contents for the older adults. Twenty six domestic web-sites were analyzed and then 12 foreign web-sites and 4 education materials for the elderly of foreign university were benchmarked. Also a lot of literatures on elderly education program were reviewed. A card-sorting task was performed with 8 older adults to ascertain how the target audience organized information about nutrition. The results were as fellows. Among 26 domestic web-sites, 2 sites(7.7%) were only for the elderly. Main topics of information contents for the elderly included 'Importance of Healthy Eating', 'DRI', 'Dietary Guidelines'. Four of twelve foreign web-sites were for the elderly nutrition education. Topics of 'Dietary Guideline', 'Meal Program' were found in 4 sites and 'Importance of Healthy Eating', 'Diet & Disease', 'DRI, 'Food Guide Pyramid', 'Nutrition Fact Labels' were found in 3 sites. Education materials of foreign university dealt with basic information on 'nutrient needs changes related with aging', 'Heart & Bone Healthy Eating Plan', 'Food Guide Pyramid'. Also topics on 'Eating on a budget', 'Eating Out Guideline' were included for practical use for the elderly. Based on card-sorting process, contents framework for web-site was developed and 4 main menus for framework were respectively named as 'Nutrition', 'Meals', 'Foods'. 'Check up Nutritional Health' by panel discussion. Finally we developed nutrition information contents for 4 main menus. We focused on helping older adults recognize the importance of healthy eating and apply the nutrition information to practical use. We expect that the developed framework of contents can be a guideline for indentifying the information needs of older adults in developing effective nutrition intervention program. And we suggest that the survey for target people should be peformed for the web-site to be user-friendly designed and the developed contents be evaluated and revised in the near future.

Physicochemical characteristics of kochujangs prepared with the powders from 4 different red pepper varieties, were investigated during 90 days fermentation to obtain information for the industrial production of traditional kochujang. Water activities and consistencies of all varities slightly decreased during fermentation, but in consistency Jangter kochujang was higher than others. The red values in color of all sample remarkably increased after 15 days. Especially L, a and b values of Hongkwang kochujang were higher than those of others. The acidities of 4 kochujangs linearly increased during fermentation. Reducing sugar contents of kochujang increased until 30 days but thereafter decreased slightly, showing highest value for Hongkwang kochujang. Ethanol contents increased until 75 days and were higher in Kumtop and Jangter kochujang. Amino and ammonia nitrogen contents rapidly increased until 30 days. Ammonia nitrogen content was gradually decreased after 30 days. Amino nitrogen contents were higher in Hongkwang kochujang.

This study was conducted to investigate the contents of residual solvents and mineral components(11 kinds) in ginseng extracts with different extracting conditions(5 types) and commercial ginseng extract products(domestic, imported). Fine root was extracted with solution having various ethanol concentration after hexane treatment. Among 5 type extracts, residual solvent(hexane) was detected ginseng extracts treated ethanol mixed with hexane. But extracts that dried after soaked in hexane wasn't detected hexane. Mineral components(Al, Mn, Fe, Cu and Zn) were detected in fine root and 5 types of extracts. The contents of mineral components between fine root and extracts with various extracting conditions were similar, however, extracts that dried after soaked in hexane showed the lower amount in Al, Fe, Pb than the others. In comparison with commercial ginseng ex-tract products(domestic, imported), the distribution pattern of mineral was similar but the contents were a little different.

The relationship of in vitro starch digestibility and gel strength was investigated at various concentrations (10-30%) of rice cultivars with different amylose contents (27.9, 17.9, and 5.2%). As the rice flour concentration increased, predicted glycemic index decreased, but gel strength increased regardless of amylose contents. Gel strength correlated strongly with amylose content, whereas in vitro starch digestibility was more highly affected by rice flour concentration than by amylose contents. Moreover, the impact of degree of gelatinization on in vitro starch digestibility of high amylose rice was also examined in terms of structural features and rheological properties. The digestion rate of fully gelatinized flour was 1.7 times higher than that of native flour, while the disrupted structure with a different gelatinization degree during starch digestion was visually demonstrated through the X-ray diffraction and molecular distribution analysis. The rice flour changed from an A-type to a V-type pattern and showed difference in crystalline melting. The low molecular weight distribution increased with increasing degree of gelatinization during starch digestion. The apparent viscosity also increased with degree of gelatinization. These results demonstrated that the starch digestibility of rice was more affected by concentration than by amylose content, as well as by the degree of gelatinization due to structural difference.

The purpose of this study was to analyze methods and contents of global Korean food marketing. In-depth interviews were conducted from July to October in 2010 using a qualitative research approach. Government agencies and restaurant companies emphasized well-being and healthy aspects as a Korean food identity. Regarding the marketing contents, government agencies commonly included standard loanword orthography and recipes. On the other hand, restaurant companies contained their own contents differentiated from other brands. Government agencies used CF, video, book and newspaper as communication channels but restaurant companies did not have systematic communication channels. Government agencies attempted to use holding, supporting and participating expositions as communication methods, whereas restaurant companies mainly used sales promotion and point-of-purchase as communication methods.

The purpose of this study was to compare the of ash and minerals contents in different types of soybeans (Baektae, Seoritae, Heuk Tae and Seomoktae) with different cooking methods. Raw, boiled and pan-fried soybean samples were prepared by the Rural Development Administration. Samples were digested by using a microwave and analyzed using ICP-OES and ICP-MS for determining the ash and minerals contents. Ash content in four raw soybeans ranged from 5.07 to 5.59 g/100g. There was no significant difference in the ash contents in raw and pan-fried soybeans (p>0.05). However, the ash content of boiled soybeans was 9 to 14% lower than that of raw soybeans (p<0.05). The minerals contents of Baektae and Seomoktae were high and the major minerals of various soybeans were K, P, Mg, and Ca, which accounted for ash 60.80-65.61%, 20.73-24.26%, 6.90-8.46% and 5.79-8.60%, respectively. The mineral contents of soybeans were significantly different depending on the type of cultivar (p<0.05), but the tendency was not constant. Because the process of soaking and boiling of soybeans made the soluble minerals elute, the ash and mineral contents were reduced. And process of pan-frying of soybeans make Because process of soaking and boiling of soybeans make soluble minerals elute (Ed- this section is very confused and seems to have 2 sentences combined: please check your intended meaning), the ash and mineral contents were reduced. As the soybeans are cooked by pan-frying, the water in the soybeans is evaporated and the mineral content is concentrated or kept constant. These results can serve as the basic data of mineral content during processing and cooking of soybeans.

The purpose of this study was to investigate the effect of enzyme-treated radish (Raphanus sativus L.) leaves on lipid metabolism in rats fed a high fat diet. Rats were divided into four experimental groups which were composed of a high fat diet group (HF group), a high fat diet with 10% radish leaf powder-supplemented group (MA group), a high fat diet with 5% enzyme-treated radish leaf powder-supplemented group (MB group) and a high fat diet with 10% enzyme-treated radish leaf powder-supplemented group (MC group). Total dietary fiber content of enzyme-treated radish leaves were greater than untreated radish leaves. Body weight gain and food efficiency ratio (FER) of the HF group increased compared to the MA, MB and MC groups. The serum total cholesterol, LDL-cholesterol and atherogenic index contents in the radish leaf powder-supplemented groups were lower than that of the HF group, while those values for the MB and MC groups were significantly lower than that of the HF group. The serum HDL-cholesterol contents of the MB and MC groups increased compared to the HF group. The hepatic triglyceride contents of the MA, MB and MC groups decreased compared to the HF group. In fact, the hepatic triglyceride contents of the MB and MC groups were significantly lower than the MA group. The hepatic total cholesterol contents of the MB and MC groups significantly decreased compared to those of the HF group. The fecal total cholesterol contents of the MA, MB and MC groups significantly increased compared to those of the HF group. These results indicate that supplementation with enzyme-treated radish leaves increase the useful fiber contents. Furthermore, it may have a pronounced impact on lipid metabolism of serum and liver in rats fed a high fat diet.

Effect of the ingestion of porphyran extracted from Porphyra yezoensis on calcium, magnesium and potassium contents in serum and tissue was investigated using hyperlipidemic and hypercholesterolemic rats. The contents of calcium magnesium and potassium in serum of rats fed porphyran for four weeks were higher than those of the control group. The contents of calcium and potassium were decreased with increasing a porphyran level while magnesium content was increased. Liver calcium contents in an $1\%$ porphyran group were significantly (p<0.05) higher than those in the control group, and magnesium contents in a $10\%$ porphyran group were higher than those in the control group. Kidney calcium and magnesium contents in rats fed porphyran were significantly (p<0.05) high compared with the control group. However, potassium content in kidney was Increased as a porphyran level was increased in diet. Spleen calcium and potassium contents were significantly lower in the porphyran groups than those in the control group. Rats fed the $5\%$ porphyran diet had higher magnesium content in spleen than any other diets. The results showed that diets supplemented with several porphyran levels had variable effects on the contents of calcium, magnesium and potassium in serum and tissue of hyperlipidemic rats.

나트륨의 과잉섭취가 고혈압의 주요한 위험요인으로 알려져 있는데, 한국인의 성인 하루 평균 소금 섭취량은 영양 섭취기준보다 3배 이상 높다. 본 연구에서는 식품교환표를 이용하여 14일간의 식단을 작성하고 조리된 음식의 나트륨 함량을 실제로 측정한 후 식품교환표와 식품성분표에서 계산된 나트륨 추정치와 비교하여, 각각 방법의 정확성 및 문제점을 파악하고자 하였다. 그 결과를 요약하면 아래와 같다. 하루 식단의 나트륨 함량에서 식품교환표로 계산한 추정치는 실측치와 유의한 차이가 났으나, 식품성분표는 실측치와 유사하였다. 음식별 절대값의 비교에서는 식품교환표로 계산한 나트륨 추정치와 식품성분표로 계산한 나트륨 추정치가 모두 실측치와 유의한 차이가 났다. 음식군별 절대값 비교에서는 양념류의 나트륨 함량이 많은 주요리, 부식, 국물요리에서 상당히 유의한 차이가 났으며, 식품교환표로 계산한 추정치, 식품성분표로 계산한 추정치, 실측치간의 차이가 큰 음식들이 모두 주요리, 부식, 국물요리였다. 이상의 결과에 따르면, 단순히 하루 식단의 나트륨 함량 비교에서 식품교환표에 비해 식품성분표의 나트륨 함량이 더 정확하다고 생각할 수 있지만, 음식별 또는 음식군별로 추정치와 실측치간의 차이를 절대값으로 비교한 결과, 식품교환표와 식품성분표의 나트륨 함량 모두 실측치와 차이가 컸다. 특히 나트륨 과잉 섭취의 주요 원인으로 보고되는 양념류의 차이로 장류, 김치 등의 사용이 많은 한국음식에서 식품교환표와 식품성분표를 이용한 추정치와 실측치의 차이가 컸다. 따라서 고혈압 및 신장질환 환자를 위한 저염식단작성시 식품교환표나 식품성분표를 사용할 때 실제 소금량과의 차이를 고려해야한다.
