It's not easy to detect the high quality and functional compounds for control quality of food materials. The electronic nose was an instrument, which comprised of an array of electronic chemical sensors with partial specificity and an appropriate pattern recognition system, capable of recognizing simple or complex odors. It can conduct fast analysis and provide simple and straightforward results and is best suited for quality control and process monitoring in the field of functional foods. Numbers of applications of an electronic nose in the functional food industry include discrimination of habitats for medicinal food materials, monitoring storage process, lipid oxidation, and quality control of food and/or processing with principal component analysis, neural network analysis and the electronic nose based on GC-SAW sensor. The electronic nose would be possibly useful for a wide variety of quality control in the functional food and plant cultivation when correlating traditional analytical instrumental data with sensory evaluation results or electronic nose data.

In this study, we improved the eggshell-membrane separation process by separating the shell and membrane with EDTA solution, evaluating effects of three different extraction solutions (acetic acid, EDTA, and phosphate solution), and co-purifying multiple eggshell proteins with two successive ion-exchange chromatography procedures (CM Sepharose Fast Flow and DEAE Sepharose Fast Flow). The recovery and residual rates of eggshell and membrane separated by the modified method with added EDTA solution were 93.88%, 91.15% and 1.01%, 2.87%, respectively. Ovocleidin-116 (OC-116) and ovocalyxin-36 (OCX-36) were obtained by loading 50 mM Na-Hepes, pH 7.5, 2 mM DTT and 350 mM NaCl buffer onto the DEAE-FF column at a flow rate of 1 mL/min, ovocleidin-17 (OC-17) was obtained by loading 100 mM NaCl, 50 mM Tris, pH 8.0 on the CM-FF column at a flow rate of 0.5 mL/min. The purities of OCX-36, OC-17 and OC-116 were 96.82%, 80.15% and 73.22%, and the recovery rates were 55.27%, 53.38% and 36.34%, respectively. Antibacterial activity test suggested that phosphate solution extract exhibited significantly higher activity against the tested bacterial strains than the acetic acid or EDTA extract, probably due to more types of proteins in the extract. These results demonstrate that this separation method is feasible and efficient.

The purpose of this study was to investigate the understanding, the perception, and the preference of Korean traditional food in 487 middle school boys and girls living in urban and rural areas. The students got 6.66/10 points in the knowledge about Korean traditional food. The girl and the student from nuclear families got significantly higher scores than the boy and the student from extended families respectively. Most of the students(95%) responded that Korean traditional food must be in succession and be developed because it suits Korean tradition of our own and our tastes. However, Korean traditional food must be improved in cooking process to more convenient way and in tastes. Especially students in urban area emphasized cooking process, and students in rural area emphasized tastes. Many students(80%) answered that the households may play the most important role in succeeding and developing Korean traditional food. Most of students(82.5%) thought that the Korean traditional food needs to be made fast food because they need to take it more easily. However, hygiene, taste and nutrition have to be considered. Pulgogi, Mandoo, Rice, Ddeokgook, Chabchae are highly preferred foods while Torantang, Mookuen-Namool, Jutgal, Jeonyoouh are poorly preferred. Some students had never tasted Shinseonro, Goocheolpan, Torantang, Chokpyun and Pyunyook.

The purpose of this study was aimed to investigate the historical tends of population growth which has reflected direct effect of the ratio of food self sufficiency in Korea between the year of 1910 and 1980. Author divided the whole years between 1910 and 1980 into five different periods ; colonial period from 1910 to 1945, post colonial period from 1945 to 1950, Korean war period from 1950 to 1955, post Korean war period from 1955 to 1960, fast economic growing period 1960~1980. The ratio of national food self sufficiency has been profoundlly affected by dual factors ; rate of population group and increment of GNP which reflect the national economic development. Total food production never reached the level of population growth ratio in Korea. As a result food demand and supply has shown imbalaced condition which leads to import foods from outside contury to compensate food shortage. The increment of GNP sharply cut down the cereal consumption. The consumption of fish, milk, eggs and meat reflected to increase since 1970.

This study was to investigate dining behaviours of 420 businessmen living in urban regions (Taegu, Gumi, Young-Chon and Chang-Won) in Kyungbuk and Kyungnam. This survey was carried out by questionnaires. The results were summarized as follows; Among all respondents, dining out once a day was most frequent. Education (p<.05), age (p<.001) and marital status (p<.001) were significant. Socialization was the most frequent reason for dining out. In the choice of food, Korean food was the most frequent (68.1%). Taste (41.4%) was the most frequently cited reason for food selection followed by variety of food (18.8%) and price (8.8%). The respondents favorite foods were: Korean food; Doen Jug Soup (31.9%); Western food; Pork Cutlet (47.6%); Chinese food; Gan Ja Jang (31.2%); Flour-bared food; Kal Gook Su (55.4%), and Fast food; Ramen (26.4%). The most frequent choices of where to eat were the company cafeteria for lunch and Korean restaurant for dinner (p<.001). Responses to inquires concerning sanitation, facilities and service were mostly "normal". They wanted lower price (30.5%), a more variable menu (24.8%), and more vegetables and fruits (18.1%) in restaurant and cafeteria food. Age (p<.05) and marital status (p＜.001) were statistically significant.

Objectives: This study investigates the relationship between smartphone usage and eating behavior among elementary school students. Methods: This survey was conducted on 4th- to 6th-grade students at elementary schools in Gangneung from September 6th to September 15th, 2023. Of the 129 copies of the questionnaire that were distributed to 5 schools, 66 copies (51.2%) were returned. Results: Compared to the nationwide statistics, the smartphone ownership rate of elementary school students in Gangneung was lower, but the rate of smartphone overdependence was higher. Smartphone dependence was 21.12 points for study subjects and 26.00 points for the overdependence risk group (Org). Compared to national statistics, the self-control failure factor was higher, so study participants in Gangneung City are thought to have great difficulty with self-control. The Org's weekend smartphone use time of 7.54 hours was significantly more than the general user group (Gug)'s 4.06 hours. The number of days in which the Org consumed late-night snacks per week was 2.92 days, and the Gug had 2.15 days, but the difference was not significant. Eating fast food showed a positive correlation with eating sweet food, eating fatty food, and eating heavily seasoned food. It was found that frequent consumption of fast food is closely correlated with unhealthy eating behavior. Weekend smartphone use time showed a significant positive correlation with smartphone dependence and the number of days late-night snacks consumed per week. Conclusions: Study participants in Gangneung are more dependent on smartphones than national statistics. Smartphone dependence had a negative correlation with healthy eating behavior and a correlation with average unhealthy eating behavior.

To standardize the recipes for healthy fast food market potentiality, a sensory acceptability analysis, instrumental texture analysis and nutritional evaluation were performed on Korean style mung bean pancake (MPC) and modified MPC containing squid meat and soybean. Optimal ingredient formulation was revealed to be 34% mung bean, 49% pork and 17% vegetables for traditional MPC, and 21% pork, 66% squid meat and 13% soybean for modified MPC, using response surface methodology. Flavor and hardness correlated highly with overall acceptability, rather than appearance and color of traditional MPC. Higher squid levels raised adhesiveness, springiness and resilience of modified MPC, but the higher soybean levels decreased these textural attributes. Protein, lipid and total calories of modified MPC were lower than those of traditional MPC. Degree of gelatinization of modified MPC was superior to traditional MPC.
