Background: The Korean government launched a project in 2008, where the amount of rice used as raw ingredient in rice-based foods in 2012 was planned to increase up to 10% (470,000 ton) of the total rice production through developing various new rice-based processed foods and their commercial manufacturing technology. Among the four major rice-based processed foods, rice cakes and noodles need rice flour as their main raw ingredient. Technology in rice flour utilization and manufacturing is far behind than the technology pertinent to wheat flour in many subject areas. Purpose: This review aims to provide information on rice flour utilization and manufacturing with some fundamental subjects in the area of size reduction. Results: A variety of food items including bread, noodle, cake, cookie, muffin, pre-mix, beverage, vinegar, surimi, and artificial meat have found rice flour as their raw ingredient. Rice bread made out of 100% rice flour has been developed and is now sold in retail stores. Various noodle products made from rice flour are also on the market. Issues on product definition and labeling regulation about rice flour content of the products were explored. Generalized grinding equations available in the literature were seldom used in practice; instead, it has been a general practice to develop empirical equations from test milling data. Introductory remarks on three popular particle size measurement methods (sieving, Coulter counter, light diffraction) were explained. Mathematical expressions frequently used to describe particle size distribution and to correlate cumulative quantity of particles with particle size were represented. Milling methods used in producing rice flour were described along with their advantages and disadvantages. Because of their profound effect on functional properties of the rice flour, four rice flour milling equipments used at both laboratory experiments and commercial manufacturing plants were discussed.

China is the largest rice producer in the world, with about 28 million hectares rice-planting area. Most of the rice is consumed domestically as daily staple food, with a small proportion consumed as feed and deep-processed products. The low elastic elasticity and low profit of rice production which hampers the development of the industry, is due to the low quality of rice grain, low processing level and undeveloped rice processing technique. Promotion of high-quality species, effective quality control, adoption of modem Processing techniques, My use of low-quality indica rice, and utilization of specialty rice are considered as priorities in rice industry.

This study was conducted to find out the desirable measures for maintenance and development traditional foods when abroad, by investigating the knowledge and actual state of utilization of Americans residing in the Los Angeles on Korean traditional foods. The 308 respondents of questionnaires were taken. 96% of the respondents demonstrated interest in traditional foods. Among kinds of traditional food, the most preferable food was boiled rice(71.4%) and Kimchi(70.9%) , The that traditional foods are used were good taste(45.4%) and familiar taste(41.6%). The reason for avoiding them was, mainly, troublesome cooking methods (46.3% ). Conclusively, the Korean Americans residing in the Los Angeles have made good use of boiled rice and Kimchi a staple common food, but special foods. ceremonial foods and festival foods were hardly used. To maintain Korean traditional foods when abroad, it is necessary that older generations sometimes offer opportunity to meet with them to the coming Korean generations, and Korean food companies develop and export standardized and simplified traditional foods.

To investigate of the utilization and awareness on the traditional foods of university students in Daejeon, 104 male students(26.8%) and 282 female students(73.2%) were surveyed by the questionnaire. The traditional foods surveyed were Korean sauce, rice cake, Korean cookies, Korean soft drinks, kimchi and ritual foods. Among respondents, 56.5% answered that they had made Korean sauce at home, and 66.2% replied the reason why was because home made Korean sauce had much better tastes than other instant Korean sauces. 40.1% of the respondents answered that they would made Korean sauce at home after getting married. 61.2% of respondents answered that they liked the rice cakes and there was a significant difference between sex(P＜0.001). Most respondents(50.7%) ate the rice cakes at traditional holidays. They liked Injulmi the most(28.4%) and there was a significant difference between sex(P＜0.001)； males liked Injeolmi better and females Patsirooduk. 47.4% of respondents liked the Korean cookies and 68.3% of them replied that the reason was because they were tasty. 71.1% of respondents ate Korean cookies at traditional holidays. 53.93% of respondents ate Korean soft drinks at traditional holidays and 68.1% of them made them at home. 81.3% of respondents said that they would make Kimchi at home instead of buying at market after they married； 65.2% of them answered the reason why was because home-made ones were tastier. For ritual foods for traditional ceremony, 52.2% of respondents said they would not use order and delivery service, and if they would use them, 60.5% respondents said because it might be convenient because it took much time to prepare. There were no significant differences between sex distinctions.

Rice production in Korea began to rise significantly after 1970. Rice is the dominant food in Korea and most of the rice production (about 95%) is consumed as cooked rice. it provides over 4,000Kj of energy per capita per day. Apparent rice availability in 2000, 93.6Kg of milled rice per person annually. The non-allergenic character of rice offers a sound basis for development of products for markets for all age groups. Whole grains are washed rice, coated rice, enriched rice in Korea. Utilization of rice as food can be categorized three categories in Korea; direct food use, processed foods, and brewing. Rice for direct consumption include regular whole grain, precooked rice, brown rice and specialty products such as aseptic cooked rice, retort cooked rice and rice burger. Rice used for processed foods includes that for cereal, soup, baby food, snack, cake, noodle, brown rice tea, and minor unclassified uses. Rice use for brewing is for the production of fermented rice wine. The use of rice for direct food is by for the greatest of the three uses. Although direct food accounts for the largest domestic consumption, a significant quantity of rice is used in processed products. The use of rice by-products as human food should not be over looked. Utilization of by products(rice germ, rice bran) requires a specialized technology. Typical type of rice is black rice. When cooked, black rice gives a black color to cooked rice. Glutinous rice performs specific functions in several commercial products such as dessert, gravis, cake and snack. Rice starch production is quite limited because of the high cost of making of starch. Rice processed products in Korea are occupied small parts of total rice production compared to Japan. Rice cake (Garadog) is the principal from of rice product consumed in Korea. Rice cake and snack is usually prepared from non-glutinous milled by washing, grinding, steaming, cooling and packaging. Rice cake will be continued to be a major rice product in Korea. Rice products represent a means to study variety differences in rice grain quality, since the processing magnifies differences not normally detected from more boiling. Recently, rice processing companies in Korea are about 400 ones which uses rice about 160,000tons. New rice processed products and modified traditional products must be developed and diversified with high quality and processing properties of rice processed products are improved.

This study intended to find out what the male and female university students in Kyung-book area think about Korean traditional foods, how much they use them, and how their life styles affect their estimates on traditional foods. They evaluated the aspects of traditional foods highly in the order of nutrition(6.07), taste(5.96), appearance(5.40), color(5.33), preservation after cooking(4.82), cost(4.63), and cooking method(4.43). Female students had higher estimates on traditional foods than male students. There was no significant difference in the evaluation between the students raised in rural and urban areas if they had the same educational level. Regardless of gender, Kimchi was most preferred followed by boiled rice, pot stew, grilled fish, and beef out of 25 traditional foods. In the correlation among the evaluation factors and uses of traditional foods, those with high evaluation on traditional foods(r=0.282, p<0.01) and the families with higher income(r=0.316, p<0.01) made more use of traditional foods. For the life style, leisure-valuing type was the greatest part(39.4%) in male students and altruistic type(31.9%) in female students. The altruistic type comprised of the greatest part(34.8%) among the students raised in urban areas and the leisure-valuing type(40.0%) among those raised in rural areas. The altruistic type students put high values on taste, nutrition, appearance, color, and preservation after cooking of the traditional foods. The egocentric type gave high values on cost and cooking method. However, there were no significant differences among the types in every item. The altruistic type put the highest and the leisure-valuing type put the lowest value on traditional foods, respectively, however, it was not significantly different. The individuality-centered type made the most use of traditional foods, whereas the leisure-valuing type made the least(p<0.05).

New gluten-free food product (tarhana) was produced using rice and com flours. Chemical and sensory properties of the tarhana samples were investigated and compared with those of traditional wheat tarhana. Generally, sensory analysis results indicated that utilization of com and rice flours in tarhana resulted in acceptable soup properties in terms of some of the sensory properties. The changes in electrophoretic properties of the proteins of the tarhana samples were also studied during the tarhana production. Sodium dodecyl sulfate-polyacryamide gel electrophoresis (SDS-PAGE) results showed that relative intensities of some of the protein bands in tarhana samples generally decreased during fermentation. The decrease was more obvious at the larger molecular weight region. Corn and rice tarhana seem to be promising food products for the celiac patients who have limited choice of cereal based foods.

The effects of dietary cellulose to utilize the intake nutrients in the albino rats were investigated by the two consecutive experiments in this study. The author wanted to observe the effects of the age of animals and different level of dietary cellulose, high and low in the first experiment and the effects of dietary cellulose from three different sources, rice bran, vegetable and pure-cellulose at high level in the second experiment. The results were summarized as follows. (1) The obvious effect of dietary cellulose caused to increase feces weight. Consequently apparent digestibilities of intake nutrients in the diet decreased. It was noteworthy that fecal glucose excretion was significantly affected by cellulose intake. Since three nutrients, protein, fat and carbohydrate serve as energy sources in the body, this result can be interpreted to be lowered in the efficiency of energy utilization out of intake from the diet. (2) The nutrients loss due to dietary cellulose resulted in reduction of skeletal muscle and bone weights which lead eventually to affect in reduction of body weight. (3) The effects of dietary cellulose showed differently according to the amount of cellulose ingested, dietary nutrients composition, the kinds of dietary cellulose supplemented and the age of experimental animals. When the intake diet was proportionately imbalanced in three different energy sources, carbohydrate, fat and protein, the cellulose intake was adversely affected in the utilization of the nutrients in the body. Cellulose from rice bran decreased body weight gain, cellulose from vegetable maintained medium level in body weight and pure-cellulose increased body weight. Growing rats showed more sensitive effects of cellulose tolerance in the body than grown rats in every concerns of this experiment.

The self-sufficiency of rice production was attained in 1975 through development of Tongil-type high-yielding rices and rapid dissemination to farmers and innovation of cultivation technologies, so-called "green revolution" in Korea. It can be continued during the last twenty seven years except some years with meterological disasters. The national average of milled rice yield per ha was only 3.1 ton at the first half of 1960′s, but it drastically increased to 5.0 ton at the 2nd half of 1990′s. Also, the rice quality was highly improved through the continuous varietal improvement of high-yielding japonica rice cultivars. The amounts of rice stock will go beyond about 1.9 million tons in 2002 due to the recent continuos bumper rice crop and relatively rapid reducing in rice consumption. There are so many rice brands over 1,200 in Korea, but most of rice commodities are not enough controlled in terms of marketing quality and palatability of cooked rice. Although the most rice brands are not properly controlled in quality management, its average level of grain quality is largely improved through the continuously increased diffusion of newly-developed high-quality rice cultivars since 1991. The rapid construction of rice processing complex(RPC) since 1992 also accelerates the production and distribution of brand rices. Especially, about half of distribution amounts are covered by brand rice commodities of the agricultural cooperative associations. The rice is mainly consumed by the type of cooked rice. The amounts of rice consumption for food processing is only below 4% of total rice consumption. The processed rice foods is mainly consumed as various processed cooked rices, rice cakes, and rice wines.
