This study was conducted to develop patties by substituting a portion of meat by bamboo (Sasa borealis) leaf extract (SBE) and/or cooked rice. Four types of patty were prepared: Control, S, SI, and SII. S was the patty for which 2.5% of meat was substituted with SBE. SI and SII were the patties with 25% or 50%, of meat, respectively, substituted with cooked rice containing SBE. The moisture contents of S, SI, and SII patties were not changed. The compositions of fat, cholesterol, and protein of S, SI, and SII patties were decreased. Cooking loss of weight as well as the diameters of S, SI, and SII patties were decreased. pH was increased in S patty, hardness was reduced in SI and SII patties, and malondialdehyde values were lowered in S, SI, and SII patties, compared to control. The S, SI, and SII patties were evaluated higher for color in sensory tests and preference tests. Through preference tests of burgers with these patties, the overall taste of the SI patty was assessed highly among the 4 patties. Therefore, it may be concluded that developing a patty by substituting a portion of meat with SBE and/or cooked rice may be worthwhile.

Rice quality is considered to have two general meanings; 1) milling, cooking, and processing quality, which refer to suitability of the grain for a particular end-use; and 2) physical quality, which means cleanliness, soundness, and freedom from foreign materials. Grain type is associated with specific milling, cooking, and processing characteristics. Thus, this experiment was conducted to classify the grain type categories and marketing grades for Korean leading rice varieties. Length: width ratio of brown rice kernel ranged from 1.57 to 2.25 and most of varieties belonged to short grain except Tongil type rice varieties. Mean of length: width ratio of brown rice kernel was 1.77 and coefficient of variance was 4.79％ in short grain type varieties. Grain shape could be further classified into 5 types by length:width ratio of brown rice kernel; 1 type(less than 1.75), 2 type(1.76∼1.80), 3 type(1.81∼1.90), 4 type(1.91∼2.00), and 5 type (greater than 2.00). For 1 and 2 type of varieties, woven wire sieve having 1.7mm openings showed better whole-kernel yields for special marketing grade, and sieve having 2.0mm openings for 3 and 4 type of varieties. Grain type which classified into 5 categories was not associated with physicochemical and cooking characteristics of rice grain, but sensory evaluation of cooked rice showed better score for 1 type varieties in terms of appearance, gloss, flavor, texture, stickiness, and taste.

The purpose of this study was to investigate quantity food production practices in foodservices by analysing the menus of April, 1996, The questionnaire was developed and responded to by 96 dietitians in Sangju, Munkyung, Gumee, Kimchun, and Andong during November, 1996. The survey was performed by simple random samplings. The results were as follosw; 1. Hospitals and industry served food for thirty days and schools for twenty days. Kimchi was a select-menu for hospitals and one side dish for industry and schools. The type of menu was a single use menu which consisted of cooked rice, soups and three side dishes. 2. The most frequently used ingredients were green onions, rice, carrots, onions, Korean radish roots, pork, eggs, glutinous rice, and milk. Kimchis were served most frequently in all food services and cooked rices and soups were next. 3. The age of most of the respondents was 26 to 30.54.2% of subjects were juniou college graduates and 77.1% were single. Fifty seven point three percent of the dietitians lived with family relatives, or friends. 87.5% of the dietitians had been working for 1 to 5 years. 4. Most foodservices were self-operated. The number of meals served was determined by meal coupon counting in hospitals(37.5%), meal board counting in industry(29.2%), and attendance card counting in schools(41.1%) The cost of sales per meal was approximately 2,450 won in hospitals and was approximately 1,100 won in industry and schools. The average number of days per menucycle was 7.4 in hospitals. 10.3 in industry and 25.5 in schools. Hospitals, industry, and schools held about 118, 265 and 263 recipes respectively. The average number of dietitians was 2.6 in hospitals and 1.0 in industry and schools. Except for the number of recipes, the general practices of foodservices were significantly different(P<0.05). 5. In the general quantity food production, food and seasonings measuring was hardly done. the percentage of foodservices using chemical seasonings was higher in hospitals and industry than in schools. the most important concern was taste, Registered cooks were employed in 75% of schools but only 50.0% in hospitals and 20.8% in industry. Most of the dietitians respinded that their cooks skill was not bad. The education of unregistered cooks was performen once or two times a month in hospitals and industry, and in schools performed everyday. The problem when educating cooks was the lack of cooking skill of the dietitians in schools, and the lack of time in hospitals, and the negative attitude toward education in industry. The method for improving cooking in all foodservices was OJT, or the extension of education facilities and the development and dissemination of standard recipes. The frequency of throwing away leftovers was higher in hospitals. But in industry, the frequency of saving leftovers was higher. 6. Though all foodservices have standard recipes, the number that used them was low, Another problem is that standard recipes resulted in leftovers. The inconveniences of using standard recipes were the difficulty of applying standard recipes to various numbers of customers the complication of use, or facility insufficiency.

This was preliminary study that was to find out the developing point in military meal service to focus on seafood dishes that recently increased plate waste. This study was conducted to analyze menu patterns in military meal service. The result of this study was using to develop new seafood dishes in military meal service. On the basis of some findings, several developing points how to plan meals include many kinds of seafood dishes and to modify taste and cooking method that was more highly prefered by young military persons were suggested. This preliminary study findings were as follows: 1. Each meal was served cooked rice and 4 kinds of dishes(soup or stew, main dish, side dish and kimchi) 2. The seafood dishes was served as 28.6% in soup or stew, 35.0% in main dish and 36.4% in side dish of total serving of seafood dishes. 3. All of raw materials of seafood were supplied by frozen, several items were supplied dried material. Supplying seafood items were limited. Numbers of using seafood items were using 2.7 times per day. Laver and squid was most frequently used. 4. Seafood dishes were frequently serving in breakfast, especially seasoned & toasted laver was served 28.8% of seafood menu in breakfast because of convenience. 5. The nutrients contents of each dishes were as follows, the soup was $86.5{\pm}3.2kcal$ and $10.9{\pm}8.9g$ of animal protein, stew was $165.3{\pm}70.2kcal$ and $13.3{\pm}7.9g$ of animal protein. Nutrients content of other main dish and side dishes was different from 108.1kcal (in steaming dish) to 412.4kcal (in deep-fat frying dish) according to different cooking method. The highest animal protein dish that contented $18.9{\pm}5.1g$ of protein was pan-frying dish or grilling dish. Lowest one was $8.4{\pm}4.9g$ in braising dish. 6. Major cooking method of seafood was stew and the next was deep fat frying, stirfrying and braising. Pan-frying or grilling was seldomly used in military menu because of limitation of kitchen facilities and cooking utensils. On the basis of these findings, newely developing military seafood menus were focused on combination dish(such as seafood cooked rice or seafood fried rice) and many kinds of sauce that was applied to deep-fat frying dishes.

This study was carried out to survey the eating behaviors and the food preferences of the tourism transportation business managers in Daegu areas by age. The survey was performed from 17 to August 25, 2003 by questionnaires and the subjects were 365 males. As a general factor, the subjects of survey were male drivers in their thirties to sixties. Their education level was middle school(44.9%) and high school(45.8%) diploma. This study showed that the managers eat three meals per day with high percentage(75.9%) and a large number of managers(24.1%) eat two meals only. 77.8% of the subjects responded that their diet life were irregular due to the property of their job. Frequency of eating-out turned out to be much higher in managers aged 60 over(p<0.001). They considered taste of the food firstly, and the prices of the food secondly, but the nutritional value of the food was considered with a low percentage(22.7%). We found that their BMI were overweight from 23.5 to 26.01, their calorie and some nutrient intakes were below their RDA. The most insufficiently consumed nutrient(less than 75% of RDA) was vitamin B₂ followed by calcium. The food preferences of subjects showed that the managers preferred boiled rice to any other rice as a staple foods. Their favorite menu of one-course Korean style meal turned out to be the bibimbob(boiled rice mixed with assorted vegetable and meat). As for subsidiary foods, out of all various meat soups, beef soups and beef-rib soups were most preferred. The most preferred stew were soybean paste stew and kimchi stew, and the most preferred cooked vegetables were cooked spinach, seasoned cucumber. Baechu kimchi(white cabbage kimchi) were the most preferred kind of kimchi. For desserts there was a very high preference for the watermelons, apples, and pears. For beverages the most preferred were ginseng tea, fruit juices and dietary fiber drinks. From the results listed above, the nutritional education needed to be done to the tourism transportation business managers to set the proper menu considering the characteristics of the preference each age group of managers.

As the main objective of rice breeding programs, rice eating quality is one of critical factors directly determining the market price and the consumer preference. However, the genetic complexity of eating quality and the difficulty in accurate evaluation often constrain improvement of the eating quality in rice breeding programs. In addition, given that the rice eating quality of current cultivars has already reached some high-level, diversifying of genetic resources are demanded more than ever to improve the rice eating quality. In this study, we developed a recombinant inbred lines (RILs) population derive from Wandoaengmi6, a japonica-type Korean weedy rice with high eating quality and a high degree of glossiness of cooked rice. Year-to-year correlations between the traits in three years were shown normal distribution for major agronomic traits and physicochemical characteristics. After evaluating tested traits related to eating quality procedure, a total of ten lines were ultimately selected from the population. Increasement of the taste of cooked rice (TA) and the overall eating quality (OE) were confirmed in the selected lines, which are caused by alleles derived from Wandoaengmi6 without any linkage drag. These results indicate that the utility of wide genomic resources in Korean landrace could be of application in various rice breeding programs and countermeasure to contribute to properly response to climate change.

This study was conducted to investigate the difference of antimicrobial activity between $\varepsilon$-polylysine/grapefruit seed extract mixture and $\varepsilon$-polylysine/glyceride mixture against food-borne pathogens. The minimum inhibitory concentration (MIC) of the $\varepsilon$-polylysine/grapefruit seed extract mixture was 100 times lower than that of the $\varepsilon$-polylysine/glyceride mixture. In case of the $\varepsilon$-polylysine/glyceride mixture the MIC of Bacillus cereus (0.1 $\mu$L/mL) and Pseudomonas aeruginosa (0.1 $\mu$L/mL) were lower than that of Escherishia coli (15 $\mu$L/mL). When rices were cooked with the $\varepsilon$-polylysine/glyceride mixture the number of total microbial cell was decreased during storage at 2$0^{\circ}C$ as concentration of the $\varepsilon$-polylysine/glyceride mixture increased. The antimicrobial activity was the highest against Escherishia coli as the concentration of the $\varepsilon$-polylysine/glyceride mixture increased. Sensory terms such as taste, flavor and texture were not significantly different in cooked rices prepared with 0.5% $\varepsilon$-polylysine/glyceride mixture, but there was significantly different in cooked rices prepared with 1% (p＜0.05) in the overall acceptability, indicating that the cooked rice with 0.5% $\varepsilon$-polylysine/glyceride mixture was recommended.

I have studied the food habits of the Yi-dynasty that wrote in umsikbup as followings ; The stape foods are Bab (boiled cooked rice) 1, Myons (noodles) 4 and Mandu 5 kinds. The side dishes are Guk (soup) 3, Sinsollo 1, Jim 9, Jijim 1, Nooruemi 6, Sun 2, Po 3, Muchim 1, Jabans 3, Jockpyuns 2, Pyunyuk 1, Chae 2, and Kimchi 1 kinds. Thare are D'ock 22, Kwajung 46, Beverages 9 and alcohol are 4 kinds. There are many kinds of Dasikk of the Kwajung in the Umsikbup than no other cooking books. The seasonings are soybean sauce 5, honey 6, oil 4 and sesame seeds 3, ect. There are the description of food types in the seasonal variation and also there are the wisdom of life and avoiding food ; toxic meats, fishes, vegetables and fruits in the taboo food. There are most of Kwajung in the Chanhap (food packed in nest of boxes) in addition to beverages, D'ock, Mandu, decoration methods in the seasonal variation. There are many food making terms which are 163 kinds of prepared cooking term 27 kinds of cutting terms and 17 kinds of boiling terms. And 18 kinds of expression of taste can be seen in this book. There are 24 kinds of table were and cooking kitchen utensils, but many of them came to usefulness 12 kinds of measuring units are very non-scientific because that is not by weight but by bulk or volume.

This study was to investigate obesity and food habit of adolescents in Yosu, Chonnam area. It was surveyed using questionnaires with 551 adolescents consisted of 280 boys and 271 girls. The questionnaire included general charac-teristics, obesity index, eating behavior and snack intake pattern. The results were as follows. The proportion of obese subjects was 10% by Rohrer index but the rate of obesity by body mass index was 3.3%. The self perception of body shape were optimal (47.9%), fat (29.8%), slightly lean (14.5%), obese (4.7%) and lean (3.1%). Generally, the propor-tion of girls responded them as “fat” was greater than boys. The greater percentage of boys responded them as “lean” than girls. The subjects don't take breakfast regularly were 50.8% and the main reason for skipping breakfast was the lack of time (55.2%). The main type of breakfast was cooked rice (78.9%). The most favorite snacks hun out to be cookies (36.5%) and 45.7% of subjects take snacks during the rest. The reason for taking snacks was “feeling hungry” (52.6％) and the taste was the most important factor of snack choice. The results of this study showed that the most of subjects were not in a serious obesity condition, and their eating habits were generally satisfactory. Also, this study has found that it is necessary to educate the students the importance of regular intake of a balanced meal. (Korean J Community Nutrition 8(2) : 129∼137, 2003)

This study was focused on identifying the difference of food preference according to body size of elementary school boys in Daejeon city. In order to measure the food preference, the degree of liking by means of a 5-point Hedonic scale was asked to 198 boys of 5th grade from six schools throughout Daejeon for 144 food items in 17 food groups composed of main dish, side dish and dessert : cooked rice, noodles or breads, as main dish, kimchi, tang.guk.zzigae, gui, zzim, bokeum, fried.pan-fried, jorim, muchim.namul or jangachi, as side dish, fruits, beverage, milk, rice cake or anacks, as dessert and for best preferred taste among five basic. The survey was conducted in rune, 1997 by questionnaires. Overall food preference of the subject was inclined to be higher in most of dessert food : fruits, beverage, milk or snacks, but to be lower in side dishes of Korean conventional food : jangachi, muchim, namul, jorim, kimchi and tang.guk .zzigae. The percentage of boys preferring cocked rice to noodle or bread as main dish was as much almost double in overweight boys as those of underweight or normal weight boys. None of the food group among 17 groups was significantly different in the food preference by body size of the subjects. However, food preference score of overweight group showed a trend to be higher in 11 food groups except less calorie-dense food groups such as fruits, noodles, rice cake, cooked rice, soup and stew and braised food (jorim) than normal or underweight group, and they seemed to prefer especially high-protein and high-fat foods. Being based on 3 points of preference score as the criterion for comparison, underweight group showed higher preference only in fruits group but showed lower preferences in 12 food groups among 17 groups than other groups.
