  • Benzo(a)pyrene [B(a)P], one of the polycyclic aromatic hydrocarbons(PAHs) is know as a potent careinogen. As consumption of lipid food and fried food increases recently, the toxic effect of overheated lipid foods has report increasingly. This study was undertaken to measure the contents of B(a)P and other PAHs of fried chicken and frying oil. At the same time, the rancidities of frying oil and descarded oil were determined. B(a)P and other PAHs contents of all samples were measured by HPLC/UV method. The results obtained were as follows; B(a)P contents of fresh chicken and soybean oil were 0.073 and 0.146 ${\mu}$g/kg, respectively. During fried chicken at 180${\pm}$5$^{\circ}C$ and 200${\pm}$5$^{\circ}C$, B(a)P and PAHs contens decreased or increased In 20 times fried chicken, PAHs contents except Pyr and DMBA increased at 180${\pm}$5$^{\circ}C$ and PAHs contents except DMBA, DBA, and 3-MC increased at 200${\pm}$5$^{\circ}C$. In frying oils fried chicken, PAHs contents increased in 10 and 15 times frying oil at 180${\pm}$5$^{\circ}C$ and grew more increase and more increase during frying at 200${\pm}$5$^{\circ}C$. The changing pattern of PAHs contents of frying oils was remotely related that of rancidities of frying oils. In fried chicken, frying oils, and discarded oils obtained from fried chicken house at market, PAHs contents of fried chickens were lower than those of fried chicken cooked at laboratory but those of frying oils and discarded oils were higher than those of frying oils cooked at laboratory.

  • As a basic study for preparing pine sprout tea, chemical components in pine sprouts and pine needles were analyzed as follows: In proximate composition the contents of most components except for crude fat were different between in pine sprouts and pine needles. Moisture content in pine sprouts was higher than that in pine needles. Calcium and potassium were major minerals contained in pine sprouts and needles, and their contents in pine needles picked in December were higher than those picked in June. Soluble tannin and vitamin C contents in leaf part of pine sprouts were much higher than those in stem part and their contents in pine needles were increased according to their growth. Free sugars like fructose, glucose and sucrose were contained in both pine sprouts and needles, and their contents in pine sprouts were higher in stem part as compared that in leaf part. Although fourteen kinds of amino acids were detected in pine sprouts and pine needles, their contents were extremely low. Amino acid composition between pine sprouts and pine needles was different each other, but major amino acids contained in them were same, those are acidic amino acids such as aspartic acid and glutamic acid. Amino acid contents in pine needles were increased according to the growth. In fatty acid composition in leaf part of pine sprouts, saturated fatty acid contents were higher than unsaturated fatty acid contents, but in stem part unsaturated fatty acid contents were higher. In pine needles the amount of saturated fatty acid was increased with the growth, but the amount of unsaturated fatty acid was rather decreased.

  • The purpose of this study was to compare the of ash and minerals contents in different types of soybeans (Baektae, Seoritae, Heuk Tae and Seomoktae) with different cooking methods. Raw, boiled and pan-fried soybean samples were prepared by the Rural Development Administration. Samples were digested by using a microwave and analyzed using ICP-OES and ICP-MS for determining the ash and minerals contents. Ash content in four raw soybeans ranged from 5.07 to 5.59 g/100g. There was no significant difference in the ash contents in raw and pan-fried soybeans (p>0.05). However, the ash content of boiled soybeans was 9 to 14% lower than that of raw soybeans (p<0.05). The minerals contents of Baektae and Seomoktae were high and the major minerals of various soybeans were K, P, Mg, and Ca, which accounted for ash 60.80-65.61%, 20.73-24.26%, 6.90-8.46% and 5.79-8.60%, respectively. The mineral contents of soybeans were significantly different depending on the type of cultivar (p<0.05), but the tendency was not constant. Because the process of soaking and boiling of soybeans made the soluble minerals elute, the ash and mineral contents were reduced. And process of pan-frying of soybeans make Because process of soaking and boiling of soybeans make soluble minerals elute (Ed- this section is very confused and seems to have 2 sentences combined: please check your intended meaning), the ash and mineral contents were reduced. As the soybeans are cooked by pan-frying, the water in the soybeans is evaporated and the mineral content is concentrated or kept constant. These results can serve as the basic data of mineral content during processing and cooking of soybeans.

  • The purpose of this study was quantitative and qualitative contents analysis of food and nutrition section in middle school textbooks of home economics, physical education and science. As a quantitative approach numbers of sentence lines tables, figures, photos, activities, and exercises were counted. As a qualitative approach, types of explanations were categorized by 7 criteria, and commons and differences of the contents of those subjects were compared. The conclusions of this study were summarized as follows: 1) Contents of food and nutrition section were divided into nutrients. water. energy, food groups, and nutritional problems. When average sentence lines of each were compared, those of nutrients were the longest in all 3 subjects. 2) When compared the numbers of tables, figures, and photos in 3 subjects of textbooks, there were more figures in home economics and science, and more tables in physical education. 3) There were more activities and exercises in home economics an science than in physical education. 4) The D(sentences with table) or E type(sentences with figure) was adapted for the explanation of nutrients functions, recommended dietary allowance, food sources, food groups, eating habits, and weight control in home economics: nutritions functions and energy metabolism in physical education : and digestion, body constituents, energy metabolism, and detection of nutrients in science. 5) Contents about classification and functions of nutrients. food sources deficiency water, energy contents of nutrients and obesity were shown in all 3 subjects. Food groups and eating habits were explained in detail in home economics whereas digestion of nutrients in the digestive tracts were explained in detail in science. Recommended dietary allowance for Koreans and basic food groups revised in 1995 were presented in home economics, whereas those revised in 1989 were presented in physical education. To avoid confusion, recommended dietary allowance for Koreans and food groups presented in physical education tex should be updated.

  • This study investigated the food and dietary educational content in primary, middle and high school textbooks in order to provide fundamental data for the development of educational programs on Korean traditional food culture. The research objects consisted of 51 kinds of textbooks (15 kinds of primary school textbooks, 29 kinds of middle school home economics textbooks and 7 kinds of high school home economics textbooks), and the contents related to food and dietary education were counted and analyzed. The content analysis was performed using two categories: application method and subject matter. Application method included texts, cases, visual aids (pictures, photos, illustrations, chart, etc.) and activities, whereas subject matter consisted of seven types (well balanced nutrition and health, understanding of food and nutrition, cooking principles, cooking lessons, traditional foods and culture, others). The results of the application method in primary school textbooks show that visual aids were the most common in all six grades. For the subject matter, 'understanding of food and nutrition' was most abundant in primary school textbooks while 'well balanced nutrition and health' accounted for a large part of the contents in middle school textbooks. However, the contents regarding traditional foods and culture were insufficient in primary and middle school textbooks. These results suggest that educational contents on traditional foods and culture should be added to primary and middle school textbooks and covered in various subjects. Furthermore, high school 'home economics' contents need to emphasize comprehensive food and dietary education and adjust to 'science & technology for life'.

  • This study was done to analyze the contents of food and nutrition information in daily newspapers. Articles in four newspapers(Chosun, Donga, Hankook, Joongang Ilbo) published during November 2003 to April 2004 were monitored. In analysis, 216 articles were used. Classifying the articles by topics, cuisine/cooking $(19.4\%)$ and food/ nutrition related to diseases $(18.1\%)$ were most common. Articles regarding food sanitation or safety, obesity and diet accounted for $12.5\%$, respectively. Other topics in articles included food culture$(11.1\%)$, balanced meals/eating habits $(10.6\%)$ and functional foods $(7.9\%)$. About $77\%$ of articles were written for unspecified persons. Regarding the types of articles, news articles made up $44\%$ of monitored articles, followed by feature articles $(14.8\%)$, advertisement by articles $(12.9\%)$, serials by professionals $(11.6\%)$, and information of daily life $(8.8\%)$. Nineteen percent of articles did not have specific sources, while $20.8\%$ were based on interviews with professionals. Other sources of articles included research reports $(14.8\%)$, field reports $(12.1\%)$ and literature $(8.8\%)$. Contents analysis showed that four-fifth of articles were evaluated as 'contents and titles are consistent', 'not difficult to understand', 'contents are not exaggerated', and 'information is not overgeneralized'. Seventy-one percent of articles were evaluated positively on increasing awareness regarding food/nutrition, while $56.5\%$ were evaluated as providing practical information. The major problems in articles were 'intentional or indirect advertisements of specific items/companies' ($74.6\%$ of articles applicable), 'lacking in scientific basis/explanation' $(65.3\%)$, 'presenting unbalanced information due to focusing on specific area' $(46.7\%)$, 'unclearness of contents' $(38.4\%)$, and 'lacking in explanation of technical terms' $(35.2\%)$. To provide reliable information, stating the sources of articles clearly and supplementing the articles with scientific basis and balanced information on specific topics are needed. It is also necessary to explain the contents and technical terms clearly and to reduce the contents of intentional, indirect advertisement in nutrition-related articles.
