Study on University Students′ Consumption Pattern and Preference of Korean Rice Cake
Korean journal of food and cookery science , volume 14, issue 2, 1998, Pages 133~139
The aim of this study was to assess University students' consumption pattern of Korean rice cakes and to analyze the preference of Korean rice cakes by their demographic backgrounds. The results of this study will be useful information for systematic development and wide distribution of Korean rice cake as a traditional Korean food. A self completed survey of 392 University students in Seoul was undertaken and detailed information was collected. The survey questionnaire consisted of three parts including demographic backgrounds, student's consumption pattern and preference of Korean rice cakes by type. Approximately half of the students were male (52.6%) with the average age of 21.1 years old. Most of the respondents (92.3%) were from nuclear families. The consumption frequency rate showed that 38.8% students had Korean rice cake once or twice a month followed by once a week (29.8%), once per six months (21.7%), and once per two months (8.2%). Ingeolmi received the highest preference score (4.15), whereas Duteopteok had the lowest score (0.18). The correlation coefficient for paired samples between students' preference of Korean rice cake and their knowledge of them was 0.827, showing statistically strong positive correlation between them.
Development of Buckwheat Bread: 1, Effects of Vital Wheat Gluten and Water-Soluble Gums on Dough Rheological Properties
Korean journal of food and cookery science , volume 14, issue 2, 1998, Pages 140~147
The rheological properties of dough made from composite flour containing 30% of buckwheat flour with 80% of extraction rate and 70% of wheat flour, with addition of vital wheat gluten and/or gums, were studied for the development of buckwheat bread. From the farinograph data, water absorption, development time, and stability of the dough decreased as the amount of buckwheat flour increased. However, the addition of gluten increased the water absorption and development time but decreased the weakness of the dough. The use of xanthan gum showed a stability-increasing effect. From the extensograph data, extension and strength of the dough decreased with increasing amount of buckwheat flour, but resistance to extension increased. The addition of gluten increased the extension and strength of the dough, but decreased the resistance to extension. Guar and xanthan gum added at 0.2% level had little effect on extensograph data of the dough. Overall, addition of, vital wheat gluten improved the properties of buckwheat bread dough better than water-soluble gums.
Study of the Korean Americans Housewives' Knowledge of Korean Festival Foods
Korean journal of food and cookery science , volume 14, issue 2, 1998, Pages 148~158
This study was to investigate the knowledge of Korean festival foods and the acculturation of American main traditional occasions among Korean American housewives residing in the New York and New Jersey area. Out of 400 questionnaires, the 271 respondents were taken. Of the respondents, 77.1% demonstrated the interest in Korean festival foods. The most important Korean festivals were Chusuk (52.0%), Sulnal(46.9%) and Daeborum (1.1%). In order to make the Korean festival foods to be international foods, the most vital factor was taste and flavor (39.5%), cooking method (34.7%), preservation (10.3%), sanitation (8.1%) and nutrition (7.4%). American Thanksgiving Day was the most important occasion among the Korean American housewives. The factors that keep the American traditional occasions were related to whether the respondents had an occupation or the length of stay in the U.S.A. But in case of Korean festival foods, the factors cannot be applied. On the contrary, they do still keep the tradition and the interest of Korean festival foods in U.S.A. As a result of that, the Korean festival foods in the U.S.A. are systemized for the preservation and popularization for the coming Korean generation.
Cooking Behavior for the Reduction of Food Wastes
Korean journal of food and cookery science , volume 14, issue 2, 1998, Pages 159~167
The purpose of this study was to investigate the cooking behavior of housewives in Seoul to reduce the food wastes. The obtained datas from the questionnaires were analyzed by SPSS program. Among the respondents 60.8% were 40 to 49 years old, and 50.l% had high school education background. Sixtyfive % had 3∼4 family members and 83.9% lived with their husbands and children. The income of 25.0% of the respondents was 1.5 to 2 million wens monthly Their housing environment showed that 37.7% of housing were private houses and 92.0% of kitchen were a stand-up type. Most respondents shopped at a supermarket (64.5%), and they expressed greate, concerns on the date of food production (58.4%) than its wastes (6.0%). Sixtyfour point nine% of the respondents prepared a kuk and chigae every meal and 46.2% of them prepared two meals at a time. Twentytwo point two% of the respondents ate all the kuk or chigae. The residual foods were kuk or chigae (47.6%), side dishes (42.3%), and main dishes (4.9%). Fortyfive point six% of the respondents believed that the improvement of eating habits needed for the reduction of food wastes.
Development of Buckwheat Bread: 2, Effects of Vital Wheat Gluten and Water-Soluble Gums on Baking and Sensory Properties
Korean journal of food and cookery science , volume 14, issue 2, 1998, Pages 168~176
The breadmaking characteristics of composite flour containing 30% of buckwheat and 70% of wheat with the addition of vital wheat gluten and water-soluble gums, were studied to establish the optimum formula for the development of buckwheat bread. The addition of vital wheat gluten or/and gums led to successful formation of buckwheat bread, giving loaf volume increase and improvement of sensory quality, especially texture determined by QDA (Quantitative Descriptive Analysis). Among those additives, xanthan gum showed the best volume expansion. Synergistic effects on bread quality were observed when the vital wheat gluten and xanthan gum or guar gum were used together. As buckwheat flour was substituted for wheat flour, gelatinization started early and the maximum viscosity increased measured by an amylography. The addition of gluten and gums caused the initial gelatinization to occur at a higher temperature and maximum viscosity to decrease.
The Changes of Physico-chemical Properties of the Frying Oils during Potato and Chicken Frying
Korean journal of food and cookery science , volume 14, issue 2, 1998, Pages 177~181
The changes of the physico-chemical characteristics of potato and chicken frying oil with frying number were examined. The changes in temperatures of frying oil during the potato flying were greater than that during the chicken frying. The weight loss of potato during deep frying was about 21.9% and about 12.3% for chicken. The acid values and conjugated dienoic acid values of the potato and chicken frying oils increased with increased frying number. Their values were greater in the chicken frying oil than in the potato frying oil. The peroxide values of frying oil did not change regularly as frying number increased. But iodine values of the frying oils decreased with increased frying number. Linoleic acid content of the frying oil decreased, whereas oleic acid content increased with frying number.
Changes in Sugar Content of Sweet Potato by Different Cooking Methods
Korean journal of food and cookery science , volume 14, issue 2, 1998, Pages 182~187
The changes in weight, reducing sugar content, sugar composition and enzyme activities (
-amylase and invertase) of sweet potato were studied with three kinds of cooking methods, microwave oven, gas oven, and steaming. The weights of sweet potato cooked by microwave oven and gas oven were decreased with increasing cooking time, whereas that of steaming was increased with cooking time. Reducing sugar content of sweet potato cooked by microwave oven was increased till 40 seconds, but decreased thereafter. In the cooking methods using gas oven and steaming, reducing sugar content were increased with cooking time. And reducing sugar content were 334.60 mg/g and 381.29 mg/g, respectively at 100
of cold point in sweet potato cooked by gas oven and steaming. Raw sweet potato consisted of fructose (1.56 mg/g), glucose (1.79 mg/g), sucrose (5.58 mg/g), and maltose (2.22 mg/g). The contents of fructose, glucose, and sucrose were decreased during cooking process. But maltose content was increased with cooking time. Especially, maltose contents were 24.81 mg/g and 28.10 mg/g at 100
of cold point in sweet potato cooked by gas oven and steaming. The activities of
-amylase and invertase were decreased with cooking time. Microwave oven-cooked sweet potato did not show on invertase activity.

Korean journal of food and cookery science , volume 14, issue 2, 1998, Pages 188~194
The purpose of this study was to provide those abroad with information about Korean foods and food culture by investigating the Japanese perception and preference for Korean foods. The results were as follows: 53.2% of the Japanese students had much interest in Korean foods and most of students (93.2%) were experience In eating Korean foods. On their first impression of Korean foods, 67.8% of the students answered that it was 'good', and 74.1% of answered their impression after eating Korean foods was 'good'. 83.1% of the students also answered that Korean foods suited their taste because they were 'delicious'. But 16.9% of the students answered that the Korean foods did not suit them because they were too spicey. The most well-known (99.3%) and eaten (96.3%) Korean food by Japanese stutents turned out to be Kimchi. In the preference test for Korean foods, Samgyetang was estimated the most delicious food. In the comparision between Korean Kimchi and Japanese Kimchi, the former was estimated more delicious and spicier than the latter.
Changes in Physical and Microbial Properties of Starchy Pastes Added Kimchi during Fermentation
Korean journal of food and cookery science , volume 14, issue 2, 1998, Pages 195~200
Wheat flour and glutinous rice pastes added Kimchi were fermented at 10
for 14 days. The numbers of total viable microorganisms and lactics were counted. Textural property by compression force and relevant changes in pectic composition were determined. Other physical properties such as color and viscosity of Kimchi juices were evaluated. Regarding the microorganism counts, the total cell counts of all Kimchi samples increased until 5th days but thereafter all decreased during fermentation. The number of lactics showed same tendency in all Kimchi samples. The compression force of control, wheat flour paste added Kimchi (WHFP-Kimchi) and glutinous rice paste added Kimchi (GLRP-Kimchi) decreased up to 72.0%, 77.0%, 66.5% respectively. During fermentation, hot water soluble pectin (HWSP) increased, whereas sodium hexametaphosphate soluble pectin (HXSP) and HCI soluble pectin (HCISP) decreased. The red chromaticity of all Kimchi juices decreased. The viscosity of all Kimchi samples decreased in the order of GLRP-Kimchi, WHFP-Kimchi and control.
