Relative crystallinities, saccharification efficiency, and diazinon(pesticide) residues of rice and rice hull puffed by hot air puffer were investigated. Crystallinities of rice starch in the puffed rice were decreased as compared to those in cooked rice, and those of rice hull were slightly decreased as compared to those in raw hull. By puffing of glutinous rice, the saccharification efficiency treated with malt amylase was higher than in cooked rice, and hydrolysis ratio of rice hull by cellulase was also increased from 14% to 30% by puffing. The residual contents of diazinon of the puffed rice and rice hull were decreased to 42.7% and 47.6%, respectively. In addition, its decreasing rate in nonglutinous rice were higher than that of glutinous rice.

The saccharification ratio and efficiency of alcohol fermentation from hot air puffed and steamed flour of husked rice and barley varieties were compared. Enzymatic hydrolysis of husked rice flour was improved by puffing, and that of glutinous rice was higher than that of nonglutinous one. By puffing of husked rice and barley, alcohol production was slightly increased, but fermentation period was reduced comparing with steam cooked husked rice and barley. Fermentation efficiencies of husked rice by puffing and rice by steam cooking were 90.72% and 87.77%, respectively. Residual reducing sugar of barley mash was higher than that of rice mash. The pH of mash was gradually increased during fermentation and was high in case of puffing treatment.

Objectives : Medical treating with eating foods is one of important therapies in East Asian traditional medical knowledge and is referred as a therapy to treat diseases through foods. Since the food cannot be separated from ordinary people living, the medical treating with eating foods is a therapy with strong locality and contains many autogenous parts. Methods : Recently, the world is showing much interest for genetic resources, and the concept of intellectual property is rapidly expanding as the field of 'new knowledge property right' as well. Thus, the knowledge of medical treating with eating foods recently draws much attention in the economic aspect beyond the scholarly interest for traditional medicine. Here, I would like to summarize and report the contents related to medical treating with eating foods on "Yi, SeikKan experience prescriptions" which was discovered before. Results & Conclusions : First, medical treating with eating porridge on "Yi, SeikKan experience prescriptions" is classified into one with nonglutinous rice as the main ingredient and the other with other grains as the main ingredient. It is differently utilized depending on the nature of the grain. Second, medical treating with eating rice on "Yi, SeikKan experience prescriptions" was born from our nation's unique way of living and is classified into one way to eat rice mixed with ground medicinal herbs, another one to cook and eat rice with mixed grains and the other way to use as the external application. Medical treating with eating rice is assumed to replace the meal. Third, "food section" was given separately and discussed in this book. There were some parts different from existing medical knowledge due to the accumulation of experience using medicinal herbs. Fourth, we should pay attention to experience a book on medicine where vibrant medical information has been recorded in order to discover and process our traditional knowledge resources as a useful form.

In order to setup the diet guideline of five grains, five meats, five fruits, and five vegetables for the diseases of five organs, I reviewed the their tastes by comparing "Naekyeong" with "Euhakibmun", "Dongeuibogam". 'Ma(麻)' in "Naekyeong" means not a hemp, a ramie or a jute, but a sesame(胡麻;참깨). 'Maik(麥)' in it means both a barley(大麥;보리) and a wheat(小麥;밀). 'Guak(藿)' in it means bean leaves(콩잎), leaves of a red-bean(팥잎) or brown seaweed(海藻;미역). 'Gyu(葵)' in "Euhakibmun Jangbujobun(臟腑條分)" is a miswritten word for 'Welsh onion' caused by similarity of shape of word. Food of a salty taste according to five elemental arrangement in "Naekyeong" is really salty according to "Euhakibmun" and "Dongeuibogam". But a barley(大麥) and a wheat(小麥) of sour taste are bitter, a chicken of sour taste or hot taste is sweet, nonglutinous millet of sour taste is sweet, an apricot of bitter taste is hot, a sesame seed of sweet taste is sour, a nonglutinous rice of hot taste is sweet, and a horsemeat of hot taste is bitter according to them. There are two ways to recommend the food for diseases of five organs. One way is to promote or control the Qi(氣) of five organs according to "Somun(素問)" and "Euhakibmun Jangbujobun", the other way is to build up the Yin(陰血) of five organs according to "Yungchu(靈樞) five tastes(五味)". The two different ways are not contradictory to each other, but complement on the view point of their substances(體) or actions(用).

Development of elderly foods that improve health among the older population is needed. The purpose of this study was to investigate the preference of specific foods for development as elderly foods. A one-to-one survey method was used for data collection from 150 elderly people attending senior welfare centers. The results of the study showed that the preferred cooking materials were vegetables, meats and fishes; and preferred cooking method was soup and stew rather than deep-frying. The elderly preferred meats and seafood but they did not eat them frequently. The results of investigating the preference of specific foods including meats, Kimchi, nuts and rice cakes indicated that old people liked broiled meats, Chinese cabbage Kimchi, walnuts and nonglutinous rice cakes the most, and they did not feel comfortable with chewing the foods. Most respondents were not familiar with the elderly foods. Moreover, the most important factors affecting their choice of elderly foods were hygiene, nutrition and flavor.

Rice cake is the most historical food which has been developed from settlement of agriculture and typical traditional food which has manufacture and food historical meaning. Because, the process of rice flour, raw ingredient of rice cake, tells remarkable food processing technology of our nation, and is original form of processed food that we has been taken before agricultural life begun. In this study, contents analysis method is used. Ingredients of rice cakes appeared in "Gyuhapchongseo" glutinous rice 12 times (42.8%), nonglutinous rice 10 times (35.7%), and the others 6 times (21.4%) used as the main ingredients of rice cake. the rice cake separated into 15 types (53.5%) of steamed rice cake, 2 types (7.1%) of pounded rice cake, 3 types (10.7%) of boiled rice cake, 7 types (25%) of sauteed rice cake, and 1 types (3.5%) of the others. it become data for knowing social and dietary culture of the time. And it is for presenting fundamental material of possibility of modern rice cake.

Rheological properties of 5% starch suspension were investigated using a capillarity tube viscometer. Nonglutinous and glutinous rice starch suspensions at $30-60^{\circ}C$, and $30-55^{\circ}C$, respectively, had no yield stress and showed dilatant flow behavior in the absence or presence of phosphate. However, flow behavior of nonglutinuous starches at $65^{\circ}C$ and glutinous starch at $60^{\circ}C$ was pseudopalastic. Flow activation energies for rice starch suspensions were 0.88-1.45 kcal/mole at $30-50^{\circ}C$ and about 45-73 kcal/mole $60-65^{\circ}C$. Flow activation energy in the presence of phosphate was 90-182 kcal/mole at $60-65^{\circ}C$. Akibare starch had the highest activation energy, and glutinous starch the lowest.

Quality characteristics of mash of takju prepared by different raw materials such at nonglutinous rice. glutinous rice, barley and wheat flour were investigated during fermentation. At the beginning stage of fermentation, ethanol content was in the range of $0{\sim}1.2%$ but it was increased to $9.8{\sim}11.6%$ after 16 day of fermentation. takju that was made of nonglutious rice with starter showed higher ethanol content than any other treatment. At the first stage, pH of takju that was made of nonglutinous rice without starter was 6.57 while other sample showed pH $5.04{\sim}5.80.$ There was no significant difference in pH value between treatments after 2 day of fermentation. Total acid was increased rapidly at the first stage of fermentation, and increased slowly after 2 day of fermentation. Takju that was made of nonglutious rice without of fermentation, and increased slowly after 2 day of fermentation. Takju that was made of nonglutious rice without addition starer showed higher total acid content than the other teratments. Total sugar contents were $19.18{\sim}20.23%$ at the beginning of fermentation, and decreased to $5.21{\sim}14.03%$ after 2-4 days of fermentation. Takju that was made of wheat flour showed higher value of total sugar during the fermentation. Reducing sugar contents of takju decreased with fermentation progressing to $0.2{\sim}0.5%$ after 16 day if fermentation. L value decreased during the fermentation. period and that of takju that was made of barley had lowest L value among the treatment. Alcohols, such as n-propanol ($nd{\sim}0.05\;mg/ml$), iso-butanol (0.02), iso-amyl alcohol ($nd{\sim}0.13$), n-hexanol ($nd{\sim}0.17$), n-heptanol ($nd{\sim}0.09$), and phenylethanol ($nd{\sim}0.02$) were detected. There were no alcohols detected at the beginning of fermentation, but their contents were increased during fermentation.

We developed a competitive indirect enzyme-linked immunosorbent assay (ciELISA) for determining the buckwheat content in processed foods by using rabbit polyclonal antibodies against buckwheat proteins (BWP). The detection limit of this assay was $0.05-100{\mu}g/mL$. The cross-reactivities of the anti-BWP antibodies toward BWP, buckwheat flour, whole buckwheat, and cereals (wheat flour, whole wheat, black bean, mung bean, red bean, brack rice, brown rice, glutinous rice, white rice, millet, African millet, nonglutinous millet, adlay, and rye) were 100, 17.9, 11.8, and 0%, respectively. Thus, the antibodies were found to be specific for buckwheat only. When buckwheat flour was heated for 30 min, the mean assay recoveries of BWP were 83.0% at $60-90^{\circ}C$ and 44.5% at $100^{\circ}C$. The spike test showed that the mean assay recoveries of buckwheat from raw noodle, boiled noodle, starch gel, and cereal flour were 99.1, 98.6, 81.1, and 104%, respectively. For the 22 commercial items tested, the qualitative coincidence ratio of assay result and the corresponding value indicated on the item's package label was 100%. However, the average quantitative coincidence ratios from 12 commercial items were 31.6%. Thus, the results suggest that ciELISA is an efficient tool to detect buckwheat in processed foods.
