To investigate the food choices and Dietary Preferences of College Women the number of dishes sold and the sales of the midmeal at the Student Cafeteria, Ewha Womans University were recorded for the fiscal year of 1974; and the observations were made on two consecutive days (June 3rd and 4th, 1974)on what a person has chosen which and how many dishes. The relationship between the number of the consecutive days and the number of foods chosen were treated as Chi square analysis. The results of the food choices and dietary preferences of College Women were as follows: 1. Breads and rice cakes, vegetable dishes, milk and milk products, rice dishes, soups, meat, fish, poultry and eggs, Kimchis and one dish meal were chosen highly; and beverages, stews, and soybeans and soybean products were chosen negligibly. 2. One dish meals, vegetable dishes, meat, fish, poultry and eggs, milk and milk products showed the highest sales volume during the year; rice dishes, breads and rice cakes were the second highest in sales amount; fried foods, snacks and Kimchis showed the range of $3{\sim}6%$ of the total sales; and the beverages, stews, soybean and soybean products were the lowest in sales amount. 3. Seasonal differences were noticed on some dishes. Breads add rice cakes, milk and milk products showed the high selections from March to November and the low, during December to February. Stews, Kimchis, beverages were kept low except sudden rise on February. One dish meal and rice dishes showed almost same level during the year but on February the slight increase were noticed; even level were kept on meat group except the increase to $13{\sim}16%$ on July and December. Fried foods were kept on similar level during the year except the increase on June. Snacks and fruits showed low selections on March, April, November and December and higher at summer. Vegetables, soups, soybean and soybean products showed no different fluctuations in selections during the year. 4. Rolls, salads, milk, hamburgers, fried vegetables, rice with mired vegetables(Bi-bim-bab), and Nang-myun were the single dishes chosen most frequently. 5. There is significant relationship at 0.05 level between the consecutive days and the number of foods chosen. It is concluded that about 50% of the population has taken one item of dishes. The popular combinations were one dish meal and soup or Kimchi; noodles and salads or fried vegetables. It is suggested to set up choice menus with the daily variations, cyclical variations and with the invariable ones; and to recommend one dish meal, breads, partial meals for school lunch; and to study to improve one dish meal, vegetable dishes and fried foods, which are new and inexpensive products. It is also suggested that the feeding of the college students should have to lead the people to the goal that the nutrition education is desired.

Swedish research in 2002 indicated that acrylamide formation was particularly associated with traditional high temperature cooking processes of certain carbohydrate-rich foods. Since the Swedish report, similar findings have been reported by researchers in numerous other countries. In 2003, three hundred and twenty seven domestic food products, selected on the basis of annual sales in Korea, were analyzed. The results were similar to those from other countries. In this study, the monitoring of acrylamide was expanded to include Korean traditional food products. Samples were purchased from local markets, prepared and then analyzed using LC/MS/MS methods. The categorized food products analyzed included cooked rices and porridges, soup products, fried products, boiled down products, seasoned products, roasted products and coffee. The acrylamide concentrations of the samples were $ND\~18ppb$ in cooked rices and porridges, $ND\~28ppb$ in soup products, $ND\~22ppb$ in fried products, $ND\~218ppb$ in boiled down products, <10ppb in seasoned and roasted products, and <10\~11ppb in brewed coffee and coffee drinks.

This study was conducted to develop food for the elderly, which are well-shaped and easy to chew and swallow. The amounts of water and gelatin were adjusted to facilitate breaking down of the food with the tongue. In the aging society, it is necessary to support the development of a variety of products that can ease the intake functions of swallowing and chewing, while complementing with the essential nutrients supplements; such products can be actively commercialized in the elderly industry. Various types of food, for elderly with difficulties in chewing and swallowing, were used for sensory assessment. Sensory panel consisted of 10 dietitians (10 women) in nursing care facilities. The sensory optimal composite recipes were determined by central composite design (CCD). The sensory measurements were significantly different in the appearance (p<0.01), saltiness (p<0.01) and overall quality (p<0.01). The optimum formulation of pan fried flat fish, calculated by numerical and graphical method, was 8.54 g of salt and 6.34 g of olive oil. Moisture content, hardness, and adhesiveness of pan fried flat fish were 84.77%, 250, and -1.20, respectively. The result showed that easily chewable and swallowable pan fried flat fish for the elderly will have sufficient competitiveness, considering its safety, taste, and preference. This study may provide the basic materials for the development of easily chewable and swallowable foods for elderly.

The carbohydrate characteristics and storability of two Korean traditional confections Seban-kangjeong (a Korean fried waxy-rice cookie) and starch-dashik (a Korean pressed starch cookie) were studied as compared with two Western confections fried cookie and biscuit. Seban-kangjeong showed lower contents of starch and sucrose and higher content of reducing sugar whereas starch-dashik showed higher contents of starch and sucrose and lower content of reducing sugar. Moisture content was higher in Korean confections than in Western confections. The degree of gelatinization was higher in Seban-kangjeong and fried cookie which were made through a frying process. Moisture adsorption isotherms were constructed for the four products. In storage test for 6 months under different temperature and humidity conditions, the relative humidity maintaining the initial moisture content of products was 68% for Seban-kangjeong and starch-dashik and 20% for fried cookie and biscuit. The ratio of retrogradation in storage was 15% in Seban-kangjeong, 20% in starchdashik and 28% in fried cookie and biscuit, showing the lowest progress in freezer storage.

The property of deep frying oil is one of die important factors in fried food quality. The purpose of this study is to identify die quality of deep frying oil in continuous usages for 4 days by two types of fryers: traditional and modified fryers. After frying polk cutlets, die flying oil was kept not only for several physical analyses such as color, viscosity, and water content but also for quality analyses of flying oil such as free fatty acid, double bond changes and oxidative rancidity formation. The fried oil by a traditional flyer was significantly increased in die physical values of color and viscosity than that by a modified fryer. In die acid value, the fried oil by a traditional fryer was significantly increased in free fatty acid than that by a modified fryer while die iodine value was significantly decreased in die fried oil by a traditional fryer when compared to control oil and fried oil by a modified fryer. In die peroxide value as an indicator of primary oxidation products, die fried oil by both fryers was significantly increased till die second day but decreased in die value after die third day because of unstable hydroperoxides' decomposition. In die p-anicidine value as an indicator of secondary oxidation products, die fried oil in a traditional fryer was significantly increased in die value than that in a modified fry.

The edible crab is among the rich resources that can be used as materials for food products, but living crabs and crabs marinated in soy sauce are the only widely utilized materials for food products. For seafood development, research is needed to promote the use of crabs in various products. In this study, the quality changes of fried rice prepared with crab meat, crab emulsion sauce and crab cooker effluent were investigated. The pH and acidity values did not show any significant difference at $-20^{\circ}C$. The acidity of the fried rice continuously increased during storage at 4 and $25^{\circ}C$. The VBN and TBA values of the fried rice stored at 4 and $25^{\circ}C$ were significantly higher than those of the fried rice stored at $-20^{\circ}C$ during the storage period. The viable cell count of the fried rice stored at $-20^{\circ}C$ changed little during the storage period while that of the fried rice stored at 4 and $25^{\circ}C$ rapidly increased over 2 weeks. For the fried rice stored at $-20^{\circ}C$, the overall quality did not show significant differences during the storage period. In conclusion, the best storage temperature for both quality and safety was found to be $-20^{\circ}C$. At such storage temperature, the quality of the stored instant rice using crab meat did not change, and through research the expanding possibilities of using crab materials were confirmed.
